Zhou Kai smoked only a small half of a cigarette, and then stopped: "Master Maverick, you don't know about this, good cigarettes burn faster, if you don't smoke continuously, it will soon burn out by itself, which will cause waste, waste is tantamount to crime, it is unacceptable." ”

Niu Xiaoqiang doesn't smoke either, so he naturally doesn't know much about it. In order to shorten the distance between the two sides, he could only follow Zhou Kai's words and say: "So that's the case, if you hadn't told me, I wouldn't know yet, it seems that everything has its way, and there are still many places I need to learn." ”

When Niu Xiaoqiang said this, Zhou Kai had already smoked the cigarette to the butt. Seeing this, Niu Xiaoqiang hurriedly took out the second one and handed it over: "I still have it here, you can order it." ”

Zhou Kai was so happy, he lit the second cigarette with the cigarette butt that had not yet been burned, and took a puff before speaking: "Master Niu, whatever you want to ask, just ask, I promise to know everything and say everything." ”

Niu Xiaoqiang saw that the other party was so polite, so he stopped being polite and began to ask some details about steelmaking. Zhou Kai really knows everything, no matter what Niu Xiaoqiang asks, he will answer it one by one. By the time it was time to eat lunch, there were not a few Hongta Mountains left in the bag that Niu Xiaoqiang had stolen from Fang Dongping, and he had almost understood the problems he wanted to understand.

"Master Zhou, thank you for your in-depth guidance, I wonder if you are free after work? I still want to ask you for some help. ”

Zhou Kai smoked Niu Xiaoqiang's half-pack of cigarettes, and he had some thoughts of inheriting Niu Xiaoqiang's favor in his heart, he did not shirk, nodded and said: "I don't have anything to do after work, but I only have time after half past six." ”

Niu Xiaoqiang sighed: "In that case, then you can tell me a location, I will go to you on time at half past six." ”

Zhou Kai pointed in the direction of the factory gate: "Let's meet at the factory gate." ”

"Okay, we'll see you then. ”

"Yes, no see, no more. ”

Before parting, Niu Xiaoqiang took out another Hongtashan and handed it to Zhou Kai, this time Zhou Kai didn't smoke it, he carefully stuffed it with Hongtashan into his big harvest cigarette box and put it away. Seeing this, Niu Xiaoqiang was curious: "Master Zhou, ...... are you?"

Zhou Kai showed an embarrassed expression: "I want to keep this cigarette and enjoy it slowly, after all, there are not many opportunities to smoke well like today, I have to cherish it." ”

Niu Xiaoqiang smiled and nodded, thinking in his heart: There are so many famous smokers.

After lunch, Niu Xiaoqiang stayed alone in the workshop office and began to analyze the contents recorded from the data room one by one, trying to find the main reason for the failure of No. 3 steel production.

On the surface, there is no problem with the production record of No. 3 steel, whether it is the temperature control or the addition of catalysts, there is no anomaly, and even the subsequent cooling link is decent, and there is no difference from the specified production requirements. Niu Xiaoqiang repeatedly scrutinized and carefully compared, but he couldn't find out what went wrong with No. 3 steel, which made him quite puzzled.

If you look at the production records, it would be impossible for No. 3 steel to be scrapped, but the fact is the opposite, No. 3 steel is not only scrapped, but also produced that peculiar ferrous metal, which suggests that there must be something undetectable omission.

Niu Xiaoqiang analyzed over and over again, but he never found the problem, and as a last resort, he could only find the reason from the upstream. If there's anything else that can change the production results, it's the upstream preparation. As for the downstream pouring and finishing steps, it is impossible to have an impact on steelmaking.

"Could it be that there is a problem with the preparation of materials? For example, there is an increase or decrease in the use of certain steelmaking materials......? It seems that this is the only way to explain it. ”

Niu Xiaoqiang came to the preparation area with such an idea, he had been here yesterday, and several preparation staff recognized him, so he didn't need other people to help introduce him.

"Hello uncles, you should still recognize me, right?"

The head preparer nodded with a smile, "Of course we recognize you, you are Elder Fang's senior apprentice, what's the matter, you came here again today to do research?"

Niu Xiaoqiang took out the cigarette box with only a few cigarettes left, took out the cigarettes inside, and said with a smile: "I want to familiarize myself with the preparation work today, I wonder if you can tell me about the work process?"

A few people saw that Niu Xiaoqiang was Hongta Mountain, the smile on his face became thicker and thicker, and the head of the material preparation staff nodded again and again: "Of course, there is no problem, when it comes to the preparation of materials, in fact, there is not too high technical content, the most important thing is to be careful, serious, in strict accordance with the requirements of the bill of lading to prepare the materials, especially to strictly control the weight of the material, not overweight or short catties or less, otherwise the follow-up production link is very likely to have problems." ”

This statement is completely consistent with Niu Xiaoqiang's own analysis, his eyes lit up, and he asked: "Uncle, I wonder if there is a problem of over-delivery or under-delivery of the materials here? If this kind of problem occurs, how should you verify it?"

The preparer replied: "As long as people will inevitably make mistakes, we can't hide it, we really have the problem of excess and shortage, as for how to verify, this is relatively simple, just weigh the remaining materials." ”

Another preparer adds: "We actually take stock every week and weigh the remaining materials in the warehouse by batch, so that problems can be identified early and corrected." ”

Niu Xiaoqiang felt that he was getting closer and closer to the truth, and continued to ask: "Uncle, you should all record data when you conduct inventory, right?"

"That's for sure. ”

"Where is all the data you record?"

"It's all in the reference room. ”

"Oh, I see, thank you. ”

Niu Xiaoqiang turned his head and ran away after speaking, and several preparers looked at the Hongta Mountain in their hands, and they all showed happy smiles, and they didn't care about Niu Xiaoqiang's sudden departure at all.

Niu Xiaoqiang met with Sister Liu, and easily blended into the data room again. With the help of Sister Liu, he quickly found the inventory list.

After some searching, he found that the next week before the production date of No. 3 steel, the preparation area found that there were ten catties more coke during the inventory, which means that No. 3 steel may have put ten catties less coke in production.

Coke is a material added in the ironmaking process, which mainly plays the role of providing heat, reducing and skeleton, and there is no other material that can replace the role in the ironmaking process.
