Chapter 355: The Second Chassis
But Yao Ran hasn't seen the drawings brought by Xiaoping, this kid is whimsical, he wants to open a mold casting tool, I really don't know if Xiaoping is a newborn calf who is not afraid of tigers, or a master of art is bold, but with Yao Ran's experience, how to look at this kid is the existence of the former.

Anyway, it was also a preliminary test, or when it was time to make a mold, so Yao Ran didn't rush to find Xiaoping to come back and revise the correction, but sat down and began to put a small stove on Yao's fire.
Because it was really too late after last night's lecture, and Yao Ran talked about too many things at one time, many Yao Huo didn't remember it very clearly, but fortunately there was a design drawing of Yao Ran's words, otherwise it would be even more troublesome.
It's not the kind of superman who can't forget, the strongest brain, or those seemingly logical, but very complex machines. You can't put it all in anyone's mind.
The master and apprentice talked and listened, and the morning passed unconsciously. At lunchtime, it was still as rich as yesterday, and of course Yao Huo ate it happily. But when he just started talking about the use of brake drums in the afternoon, Xiaolong, a disciple of Yao Ran who had been entrusted by Yao Huo, rushed over.
It turned out that the progress was reported, and this was also the work that Yao Ran asked Xiaolong to do, that is, when the progress of the steam locomotive reached a progress node, Yao Ran needed to check it in person.
In fact, this kind of node customization is for reorganization, even if Yao Ran once made an overall correction when assembling the chassis of the first auxiliary car, he had already told Xiaolong a lot of things that were prone to errors, and especially sorted them out.
But there is no way to avoid all the problems, whether it is negligence or equipment parts, problems are inevitable, so the first steam locomotive, Yao Ran made such a large, two parallel vehicles, one of several starting points, is also to accumulate enough experience in the production of steam locomotives.
Experience can be passed on by word of mouth, of course, it can also be applied to paper, in this way, experienced technicians, plus a brief introduction to the drawings that can be queried by text, when it comes to inspecting the machine, so that there is a regular query, then there is no need for Yao Ran to supervise when it comes to production.
And Xiaolong is the person recommended by Yao Huo to Yao Ran, Yao Ran uses it more smoothly, the steam locomotive project is not a small project, and it can be said that it is a risky act to use such a student who has just come out of school.
But where is the voice not an adventure, Yao Ran Yao Huo went out, because they didn't want to delay time, the three of them got on the alpaca car directly and went straight to the steam locomotive workshop.
After the time for tea was up, Yao Ran began to work, and the inspection work, of course, Yao Ran was doing it, but this look, it still had to be done enough, according to the instructions written by Yao Ran Xiaolong, and all the processes on the inspection and quality inspection manual.
The problems that occurred this time were far less than the last time, but the problems still existed, and there were two repeated problems, and one of the new problems was that the quality of the equipment was unqualified, and no one could check this problem except Yao Ran.
This is also a problem for the industrialization of the entire Yao clan, how to improve the quality of parts and components, of course, it is better to reduce the use of cast iron parts, and replace all steel, even if it is relatively high carbon content. It is also better than all the casts are directly cast with pig iron, and the quality of the parts is passable.
But the technology has not reached that level, including the use of alloy materials, which Yao Ran wants now, if there is a barrel, many equipment can not only reduce weight but also improve the level of production when manufacturing.
The problem is that aluminum ore and copper ore Yao Ran has been able to see trace elements in the soil unexpectedly have not been found unexpectedly, and those minerals necessary for industrial production can be seen there.
Yao Ran once again took the lead, all these problems were solved and he led someone to replace the substandard part, and when this part was replaced, Yao Ran didn't say anything, just said.
"This part needs to be changed, but you don't need to record it, you are easy to be confused by writing it down, and it is easier to understand the problem here, so you don't need to understand this." Yao Ran's words caused a lot of people to be confused, and Yao Huo was obviously stunned for a moment.
But because Yao Huo has been by Yao Ran's side for a long time, Yao Huo understands many problems, and the teacher doesn't say that it is really to prevent the people who are learning from being too confused and causing a situation that is more difficult to understand.
But Yao Huo wanted to try what the problem was, so Yao Huo jumped to the ground next to the steam engine, picked up the parts in his hand and looked left and right, and also tossed the weight in his hand, and picked up another part of similar size, and after flipping it, Yao Huo found the problem.
There is almost no difference in the size of these two parts, but the weight can make people feel the difference obviously, because there is a difference in the quality of the piece that Yao Ran replaced, and Yao Ran really forgot about this stubble.
The retina system scanned, and it was really like this, the parts with questionable quality, because when casting, it may be because the temperature of the molten iron is too low, so in the whole casting process, there are many gaps inside the parts that are not completely filled, which is also the reason why this part is lighter than other parts of the same size.
The specific gravity of this work is once again added to the inspection of parts, after all, it is still possible to avoid some problems, as long as it can reduce the existence of an error, it is already very profitable.
Yao Ran took a few people to spend an afternoon to solve all the problems again, and all of them were recorded by Xiaolong, Yao Ran and Xiaolong asked for the notepad.
I'm going to go back and sort out all the records myself, and there are caveats. Then write out a full flow chart according to the drawings one by one, precautions appendix, inspection standard diagram, respectively, by three people for re-inspection, the flow chart is of course for the installation workers to refer to and use, and the precautions are responsible for the project, can also be called the section leader to correspond.
And the last inspection standard catalogue is for those inspectors and quality inspectors, of course, there is also the overall person in charge, at present, the overall person in charge is Yao Ran, but Yao Ran as soon as he gets off a steam locomotive, the overall person in charge may be Xiaolong.
Because Yao Ran will complete this steam locomotive, after the combination of the two at the same time is completed, Yao Ran will begin to prepare for the formation of the northern slope of the Daxue Mountain in the north, and the tracked land reclamation steam locomotive behind.
