Master Lin's expression was a little scary. With a cold face, he said with a hint of hatred,
"Little Song, answer me seriously. Is there someone in the black market buying this thing? Are you tempted?"
Sighing, Master Lin continued,""I've long heard that there were people in the north who were doing this, but I didn't expect you to be so insensible and participate in such a dirty thing.”
"It's not a problem to make a spoon or something, but do you know what this behavior is?”
"It's not just a robbery. It's a serious crime. Do you understand? If you catch it, you'll be finished.”
"Hurry up and take it back. I'll pretend I didn't see it today. You can't have such thoughts, understand?”
"Also, tell me, who urged you to do this? I'll report him to the security department. This kind of destructive and selfish guy has to be arrested.”
This sentence was harsh and fast, directly beating Song Qingshan into a daze.
Song Qingshan didn't understand when he heard it. What was this?
However, he understood after thinking about it for a moment.
Nowadays, some people in the north had started to do that kind of business.
No wonder Master Lin had thought of that after taking a glance.
They probably wouldn't have thought that a rookie like him was going to modify the rolling mill.
Looking at Master Lin's pained and angry appearance, she did not forget to cover up for him despite her disappointment.
If it were any other master, they might have reported it to you first.
Song Qingshan was extremely touched. This was really treating him as one of his own.
In his heart, he had already treated Master Lin as his own elder.
He quickly pointed at the blueprint.
"Master, please take a closer look." He didn't know whether to laugh or cry.”
“？？？”
Master Lin was a little surprised. Could it be that his judgment was wrong?
However, if he didn't sell it, his family wouldn't need it. He immediately picked up the blueprint and looked at it seriously.
"Yeah, it looks familiar." Master Lin muttered.
He glanced at Song Qingshan and took the blueprint to a brighter place to continue studying.
Song Qingshan smiled and didn't say anything.
After a while.
" Electric motor, gear clutch, decelerator, gear clutch, herringbone gear seat, universal joint shaft bracket, universal joint shaft, working base."
" Electric Screwdown Device, Balance Device, Working Wheel Assembly, Supporting Wheel Assembly, Racking Device, Track Seat "
Master Lin muttered.
"Are you going to modify the rolling mill?"”
"You're really amazing. You can even see through such a sloppy drawing.”
Song Qingshan said in admiration.
Time was limited, and the drawings he drew were actually quite rough.
Only the size were accurately marked out.
As expected of a veteran operator who had been around for decades. He thought he had to explain himself.
"Change the work roll shaft diameter to 250mm and 620mm?”
"The work roll shaft diameter is 310mm?”
"The diameter of the support roll is 500mm, and the diameter is 1240mm?”
"Why did you change it like this?" Master Lin asked directly.
"For the four-mixing mill, in order to reduce the rolling force, the diameter of the working spoke should be as small as possible. However, the minimum diameter of the working rod could be changed to this size due to the rotational strength of the journal and the shaft head, as well as the biting conditions.”
Song Qingshan did not show any fear and answered generously.
Master Lin thought about it and continued to ask,"Why do you need spherical cast iron?"
" Ductile iron is a new sand casting process."
"I know that. Tell me why you want to use this. How did you judge?" Master Lin interrupted this sentence and let Song Qingshan continue.
"Alright, it's the rolling force requirement of the rolling mill.”
"If the work roll and support roll become smaller, the bending capacity, the basic rated dynamic load, and the axis force. There will be changes."
"The reaction force at the work roll bearings, the radius of the friction circle, the roll driving moment, the friction coefficient, and the power of the motor also need to be changed.”
"Compared to cast iron, spherical cast iron has an absolute advantage in terms of strength.”
"Ductile iron has a strength of 60K, while cast iron only has a strength of 31K. Ductile iron had a yield strength of 40K, but cast iron did not show any yield strength.”
"The strength and cost ratio of spherical cast iron are far superior to cast iron.”
"Corrosion resistance, oxygen resistance, spherical graphene structure, and vibration reduction ability are better than cast steel. It won't break easily."
Master Lin smiled in satisfaction.
"But where are the sliding gears and rails used?" he asked with confusion. Where was he going to add this?”
When Song Qingshan heard this, he finally got to the point.
He pointed at the sliding gears and tracks on the blueprint and said with a smile,
"The rail installation station.”
" The sliding gears are used to modify the transmission and the electric motor. In addition, a part of the synchronous track belt is added. The connection and transmission can be realized through the connection between a series of transmission mechanisms driven by the electric motor."
"We can achieve the initial stage of semi-automaton.”
"In this way, the first two steps in the process of rolling the plate can be automated.”
"The production efficiency can also be greatly improved, and the precision and thickness of the plate will also be greatly improved.”
Song Qingshan quickly explained the idea of the transformation in one breath.
He was a little thirsty and was about to find water to drink.
Master Lin had already handed over the porcelain cup.
