On the afternoon of the day the regiment team finished unloading the pig iron, I had asked the workshop material staff of the Third Company to come to the materials department office to check the acceptance and handover procedures of the five tons of pig iron. He had something to do and asked me to go over.
I went to Third Company and found the material staff in the workshop. I went through the relevant procedures for the acceptance and transfer of the five tons of pig iron to them. After I finished my work in the workshop office of Third Company, I stood at the door of the workshop and found a stranger. I had never seen him before, so I didn't know where he came from. I watched him in Third Company's scrap steel yard, constantly flipping a scrap iron pipe about 1 meter in diameter and 2 meters long. He couldn't help but raise his guard. He had to investigate that person's background.
So, I immediately asked a worker standing next to me,""What does that person do?"
The worker replied,"We've never seen this person before. I don't know him either." It was safe to say that there was no such person in the workshop.”
I immediately took action. I walked forward and stretched out my hand to stop the person who was flipping through the scrap iron pipe in the scrap steel yard."May I ask what you do? Who gave you permission to come here? What do you want? What do you want to do here?"
When that person saw that I was so impolite to him and asked questions like a cannon, he quickly understood me. I had already developed doubts about his background. He quickly stood up and answered me,"Don't misunderstand, I'm not a bad person. I'm looking for this component. I've been looking for this component for a long time.”
He handed me a recommendation letter. I took it and saw that it was stamped with the official seal of Chengdu City Medicinal Herbs Company.
He continued to say that they wanted to ask our factory for help and sell this iron casting to them to make a component for the production of Chinese patent medicine. Ask me if I can? Would they be able to satisfy their demands?
I immediately told him,"Please wait a moment. I don't have the final say in this problem. We need to study it immediately."”
After that, I turned around and entered the office of Third Company. I found the workshop director of Third Company and asked him if he still wanted the old cast iron pipe in the scrap steel yard.
The workshop director smiled at me and said unhurriedly,"If we want it, we'll break it and use it as scrap steel. However, that object is too big, but it's quite troublesome to break it, so we left it there and never touched it. If we say we don't want it, it's because that guy isn't an official artifact. That section of pipe was also brought over by another unit when they sent scrap iron. Why are you asking this?"
I said,"I want to say this first. If you're sure you don't want it, then I'll get rid of it.”
The workshop director answered readily,"Then you should dispose of it. Otherwise, it will always be placed in a pile of scrap steel. Such a big thing will take up quite a lot of space.”
With the words of the workshop director of Third Company, I had a little confidence in my heart. I then called the security department in the factory. I asked them to help me find the phone number and company address of the Chengdu City Medicinal Herbs Company. After a while, the security department returned a call. I made a note.
After putting down the phone, I took the recommendation letter from the person just now and looked at the phone number and company address on it. It matched the phone number and company address on the phone record. The conclusion was exactly the same. I have a plan now. That person wasn't lying. He was telling the truth.
As for whether it can be done, I think we should report to our section chief first. I can't make the decision. However, he could suggest it to the Section Chief. This was because the workshop director of Third Company had already made his stance clear. He needed to make space and sell that piece of waste pipe. He could still sell it for a few dollars. It could more or less increase the factory's income.
So, I turned around and walked out of Third Company's office. I found the person from the Chinese medicine company and told him,""I'm going to the factory now to report to the relevant departments. If there's no problem, come with me to the factory to settle the relevant procedures.”
Back at the materials department office, I stopped that person outside the door first. I entered the office first and reported what had just happened and my suggestions to my old section chief in a concise manner. I also asked for his opinion.
"Aren't you afraid that people will talk behind your back and say that you're a capitalist if you sell that scrap pipe as an iron casting?”
I replied," The factory's finance department will collect the money for the things I've dealt with. I can't get a single cent personally. The whole process is open to the public. There were no secrets to speak of. I think I can explain it clearly. The key question now is, I want your support and approval. Do you agree or not?”
At this moment, the old Section Chief said ambiguously,"Then you should do a good calculation. As long as we don't suffer losses, it's fine.”
Since the Section Chief had already said so, he did not object to doing this. He just wanted to not suffer any losses. Then I can do it openly.
Hence, he decided to do it. I went outside the door first and invited that person into the office to sit down. I brought him a cup of tea and settled him down before sitting down at my desk. I need to adjust my train of thought. He began to calculate. I didn't know how to calculate, but once I picked up the pen, I was a little confused.
As the saying goes,"When a book is used, it is hard to find it."”Moreover, there were even fewer books on geometry in that era. I'll ask Master Shang for advice on how to calculate it. Master Shang looked at me, a little unhappy. "Where's the old school?" he said disapprovingly.”
I scratched my head and said embarrassedly,"Don't scold me first." Give me a hint."
Master Shang took out a piece of paper and wrote a line of words,"The weight is equal to the area multiplied by the thickness and then multiplied by the specific gravity."”
After receiving this note, I seemed to have some ideas.
According to Master Shang's instructions, he first calculated the area. It was not easy to calculate the area. Because this section was a socket type cast iron pipe, the caliber of the water in and out was different.
I can only calculate it first. The area of the straight pipe was multiplied by pi. Subtracting the thickness of the cast iron pipe, the circumference of the straight part of the cast iron pipe was obtained. Multiply the circumference of the pipe by the length of the straight pipe. The area of the straight section of the cast iron pipe was obtained.
What was difficult to calculate was the section that was inserted into the street. The shape was like a bowl sitting on the head of the tube. Since I didn't have a manual to refer to, I had to use an area that was close to that of a sphere.
It's the outer surface of the sphere. I didn't learn this formula in school. I can only give up on this calculation method.
It seemed that this method would not work. The difficulty was too great, so he had to think of another way. He watched as Master Shang went out to handle some matters. I thought of a way to slack off. Using an approximate calculation method. Anyway, I'm only using it this once, and it won't happen again.
He began to calculate the weight of the cast iron pipe in front of the person from the Chengdu Traditional Chinese Medicine Company. Using the method of analytical geometry, he referred to the ring calculation formula and the cylinder calculation formula. He had been calculating for a while, but he still could not figure it out.
At that time, there were no calculators, so they could only calculate by hand and pen, or use an abacus. After I calmed down, I pulled open my desk and took out my brother's math textbook. Finally, I found the basic calculation formula: "(R*R-r*r)*3.14*L" he quickly copied on the paper.
According to this calculation formula, using the basic principles of algebra, the outer radius R of this section of cast iron pipe is determined to be 0.512m, and the inner radius r is determined to be 0.500m. I have used the approximate values for the outer diameter and inner diameter of this section of pipe fitting respectively, and the size is slightly controlled. The length was 2 meters. The weight of the cast iron pipe was 7.85 tons per cubic meter.
Finally, he calculated the weight of the cast iron pipe. The final cost of this cast iron pipe was calculated according to the estimated price of Wuye's materials in 1974.
The result was obvious. The price of the cast iron pipe would definitely be higher than the price of the waste pipe. No matter how they calculated it, as long as the weight was correct. He definitely wouldn't suffer a loss in this transaction.
When I finished filling in the sales list and asked the old section chief to sign it, I brought the person from the Chinese medicine company to the finance department to complete the payment procedures. I returned to the Third Company Forging Workshop and instructed the shovel driver to transfer the cast iron pipe to the roadside at the factory entrance. I marked it with the sign that it had been sold, and the people from the Chinese medicine company would pick it up themselves.
Later, Master Shang looked at the stubs left behind by the discarded pipe that I had disposed of. He took out a material manual and compared it with the main parameters of the pipe. I compared the results of my calculations with the results found in the manual. The error was within two percent. The data was basically reliable.
Later, Master Shang warned me. He had to use his brain more in the future. At that time, I didn't want to talk to you too much. Their purpose was to stop you, but you were a little rash in doing this. It was alright. Nothing had happened yet. No one said anything. This matter was over. You did get rid of the pipe. If no one comes looking for revenge, I'll let you off.
"What if the company asks you to provide a certificate of qualification?" Master Shang continued. Can you take it out? Definitely not. You don't even know where this pipe came from. How could he take out a material certificate?”
I was tongue-tied. Who didn't speak?
"What if the pipe was used by someone else and burst due to the material itself?" Master Shang continued. Who will bear this responsibility?" What if the pipe burst when someone else used it due to the material itself? Who would bear this responsibility?
I started to sweat.
Master Shang paused for a moment and continued,""Don't just look at the money and do things recklessly. Everything we do has to stand the test of time. Now is not the time for you to be a model maker. Your product is bad or wrong. If the inspection failed, the section chief, Master Yang, would not stamp the special seal for you, and it would not be passed to the next process. And now, you have all kinds of materials in your hands. Every order you sign is directly used as an important basis by others. Everything you do doesn't represent yourself. It represents our factory. Have you figured out the powerful relationship between them?”
I heard everything Master Shang said. The more he thought about it, the more afraid he felt.
Master Shang was probably tired of talking. After a pause, he continued," Thinking back, I'm really afraid for you. If something really happens in the future, our factory's reputation will be affected. Think about how much responsibility you should bear. And you're definitely not the only one who's being punished. It would involve a large number of people. You've been here for so long, and I've always been very tolerant of you. Perhaps I've spoiled you. I have to teach you a good lesson. So I said. You're too rash in this matter. It's time for you to sum up your experience and lessons.”
The lesson I learned this time was too deep. In the next few decades. I've met many students. I often tell this to my students. If they were asked to do something, they had to think carefully and look around. Don't be greedy. When doing things, one must have a basis. He had to foresee the consequences.
In October 1975, the section chief wanted to take me to the city gate of Peng County, Sichuan Province to pick up the goods. The location was an agricultural machinery repair shop on Peng County Street. The task was to pull back the oxygen cylinder cap that our factory had entrusted them to process.
