Chapter 150 Upgrade
“Oh?”

Yu Wenzhen became interested.

He was a little curious about why Ding Shigui was looking for him.

After all, the equipment in a workshop has been renovated and everything that needs to be replaced has been replaced. What else is worth Ding Shigui personally requesting?

Ding Shigui organized his words and said, “It’s like this. Our fitter workshop is the earliest workshop established in our steel rolling mill. We use machine tools imported from Russia, such as rolling mills and converters. Other workshops use relatively new equipment. Now my workshop is always at the bottom, and I…”

Listening to Ding Shigui’s story, Yu Wenzhen gradually understood.

The simple thing is that the fitter workshop is always at the bottom of the list. Although Yang Zhiwei and other factory leaders didn’t say anything, he himself couldn’t stand it anymore.

He really couldn’t accept that the output of one workshop lagged so far behind that of other workshops.

Therefore, this time Ding Shigui came to Yu Wenzhen to ask for his help, whether it was transformation or redesign, he wanted to increase the output of a workshop.

Yu Wen Zheng frowned as he thought, his fingers tapping rhythmically on the desk.

The backwardness of the machine tools and converters in the fitter workshop is indeed a big problem, which greatly restricts the production efficiency of the workshop.

However, the equipment in a workshop is already so old that instead of wasting time on transformation and upgrading, it is better to redesign it.

He kept flipping through the knowledge in his mind.

Suddenly, his fingers hovered in the air.

I have an idea.

For a rolling mill, you can design a continuous rolling mill, but for a converter, there are two options.

One is the oxygen top or bottom blowing converter, and the other is the top and bottom combined blowing oxygen converter.

The first converter was invented overseas and is now widely used.

As for the second one, it is a steelmaking technology that was only developed in the 80s.

Compared with the first one, the second one is equivalent to an upgraded version of the first one.

Top and bottom combined oxygen converter steelmaking has the advantages of top-blown converter steelmaking, which is good slag removal and large amount of scrap steel consumption.

At the same time, it also has the advantages of good stirring of the oxygen bottom blowing converter steelmaking molten pool, less iron and manganese oxidation loss, and less metal splashing.

Yu Wenzheng turned his gaze to Ding Shigui with a smile on his face: “Director Ding, the open-hearth steelmaking method is already very backward. I do not recommend upgrading it.”

When Ding Shigui heard this, an expression of disappointment appeared on his face.

He thought Yu Wen Zheng was politely refusing him, so he nodded and was about to get up, but he didn’t expect Yu Wen Zheng to stop him.

“Director Ding, I haven’t finished speaking yet.”

Ding Shigui paused and looked at Yu Wenzhen in confusion.

Yu Wenzhen waved his hand and motioned him to sit down.

After Ding Shigui sat back down, Yu Wenzheng spoke up, “The open-hearth steelmaking method is already outdated, and there is no need to reform it, but I have two plans. Please listen to them.”

Ding Shigui nodded hurriedly.

Yu Wenzhen took a blank piece of paper, wrote “oxygen top/bottom blowing converter” on it, and then put the paper on the desk.

Ding Shigui’s eyes lit up.

He knew that this type of steelmaking equipment was a steelmaking method that had been widely used in developed countries overseas.

He asked cautiously, “Director Yu, do you have this steelmaking method here?”

Yu Wenzhen nodded and smiled without saying anything.

Ding Shigui said excitedly: “That’s great.”

“Director Ding, I know you are very excited, but please don’t get too excited yet.” Yu Wenzhen saw that if he didn’t stop Ding Shigui, he would just dance on the spot, so he quickly spoke to comfort him.

Ding Shigui smiled awkwardly, his strong expression returned to normal, and he sat upright waiting for Yu Wenzhen’s next words.

Yu Wenzhen took the paper back from the desk and wrote “Top and Bottom Blowing Oxygen Converter” on it.

When Yu Wenzhen handed the paper to Ding Shigui, his eyes became confused after he finished reading it.

He had never heard of the top and bottom blowing oxygen converter steelmaking method.

However, as the name suggests, this steelmaking method seems to combine the advantages of oxygen top blowing and oxygen bottom blowing.

Although he had some guesses in his mind, he couldn’t be sure.

He turned his gaze back to Yu Wenzheng and asked, “Director Yu, what kind of steelmaking method is this? Forgive my ignorance, I have never heard of this method.”

Yu Wenzhen smiled inwardly.

It would be strange if you have heard of it. This is a steelmaking method that was only invented in the 1980s, and people overseas haven’t even thought about it yet.

“Director Ding, you know the first method of steelmaking, so I won’t explain it in detail. As for the second method…”

Yu Wenzhen left the audience in suspense here, whetting their appetite.

Ding Shigui became anxious when he saw Yu Wenzheng didn’t say anything. He asked anxiously, “Director Yu, how about the second option?”

Yu Wenzheng grinned and explained, “It’s nothing. The technology is more advanced and more efficient than the first one.”

Ding Shigui was stunned for a moment when he heard this. The surprise came too suddenly.

He didn’t expect that he would receive such a big surprise after making up his mind to come to Yu Wenzhen for support.

If the first steelmaking method can make a workshop the most efficient workshop in the entire factory, then the second method can make a workshop at the world’s leading level.

After swallowing his saliva, Ding Shigui asked, “Director Yu, is this “Top and Bottom Blowing Oxygen Converter” too troublesome?”

What he actually wanted to ask was whether the research and development time would be too long if a top and bottom blowing oxygen converter was chosen.

But when the words reached his throat, he instantly changed his tone.

Yu Wenzheng shook his head and said, “What’s the trouble? After all, the top-bottom combined oxygen converter is just an upgraded version of the top-blown oxygen converter and the bottom-blown oxygen converter. Director Ding, I won’t hide it from you. If you choose the second option, then the first workshop will be responsible for testing the data and prepare for the future popularization of the whole factory.”

Ding Shigui frowned upon hearing this and said, “Director Yu, our workshop is responsible for the data of the continuous rolling mill, but the converter…”

Yu Wenzhen’s expression changed, and he felt that Ding Shigui was somewhat unreliable.

Ding Shigui noticed that Yu Wenzheng looked a little strange, and quickly waved his hand to explain: “Director Yu, please don’t misunderstand me. It’s like this, our fitter workshop only needs the continuous rolling mill. This converter is the equipment of the steelmaking workshop, and I can’t make the decision.”

Yu Wenzhen’s face turned dark, and a few black lines slowly descended from the top of his head.

What the hell.

This is not the equipment in your workshop, why are you wasting your time talking to me?

What do you mean?
Are you making fun of me?
Yu Wenzheng looked at Ding Shigui expressionlessly and said quietly, “Director Ding, this is not very kind of you. This is not the equipment in your workshop, but you are wasting your time talking to me.”

“no no.”

Ding Shigui waved his hands and explained, “It’s like this. At present, the converter is still working in our workshop, but some time ago, Director Yang held a meeting and said that a steelmaking workshop would be established. When the workshop is vacated, all the converters will be transferred to the steelmaking workshop, and then I will not be in charge of it. I just didn’t think of it for a while, and I didn’t mean to make fun of you.”

After listening to Ding Shigui’s explanation, Yu Wenzhen’s expression finally looked better.

But he was a little confused.

Why do we suddenly need to set up a steelmaking workshop?
He did not attend the last meeting and Yang Zhiwei did not mention this matter, so Yu Wenzhen had no idea about it at all.
