The atmosphere of the scene was intense, Zhang Lao waved his arms vigorously, and at the same time sighed, tilting his head to Huang Lao beside him and said, "I like this kid a little." ”

Huang Lao laughed, "Old squad leader, you can't beat him, otherwise I will have to sue my sister-in-law." ”

"Haha"

The two laughed.

Click

Not far away, Liu Lixue held a camera and recorded this warm scene.

When the singing stops, when people's passion is released, the blood is still surging in the veins.

Zhang Lao and others were also infected and tried to restore calm.

"Old squad leader, let's get down to business today."

Huang Lao looked at the people around him, and then looked at the time, he came here early this morning, and today's business is the experiment of the oxygen top blowing converter.

Zhang Lao smiled, "It's a serious matter for you, but for me, the workshop in front of me is my main business." ”

Huang Lao shook his head, "That's not good, this is for the converter experiment, if you want to use it, go back and let the machinery factory make two of them, and build a new workshop." ”

Zhang Lao pointed at Huang Lao and smiled, "You guy." ”

"Don't talk about anything else, prepare twenty tons for me this week, and it's urgent."

Huang Lao nodded when he heard this, and said to Yang Xiaotao, "Xiao Yang, did you hear it, twenty tons." ”

"Yes, chief, make sure to complete the task."

Huang Lao nodded, and added at the end, "Go out of the warehouse according to the order." ”

Yang Xiaotao was stunned for a moment, and then laughed.

Zhang Lao pointed and smiled when he heard this, "Don't worry, what should be given is definitely not a lot." ”

Then he looked at Yang Xiaotao, "Twenty tons of base, how much is the excess, how much do I want." Give it together. ”

Yang Xiaotao smiled, "Chief, don't worry, we, we're not afraid of not being able to complete the task, but we're afraid of not having a task." ”

Hahaha

Behind the crowd, after Guan Zhiyong heard it, he immediately clenched his fists and whispered to the workshop director beside him, "Did you hear it, what did the leader say, did you hear it?" ”

The director nodded excitedly, "Don't worry, the factory director will start two shifts today, not to mention twenty tons, even if it is doubled, it will be made for him." ”

Guan Zhiyong nodded with satisfaction, these are all task rewards.

I think that their steel mill has finally been able to gather wool, but they have to seize this opportunity to compare.

After the conversation, everyone set off for their destination.

Outside the converter workshop.

An Zhongsheng took Zhang Hongxian and Li Junming for the final examination.

"How is the crane ready? What happens to the blast furnace? ”

An Zhongsheng was wearing a hard hat and long-sleeved overalls, although the wind was cold, he rolled his sleeves up to his elbows and held a folder in his hand, which was unprecedentedly dignified.

"The overhead crane has been inspected correctly, and the molten iron in the blast furnace has been prepared."

Zhang Hongxian reported that although he was the head of the R&D section, he had already put this identity aside in his work during this time, coupled with An Zhongsheng's own technical ability, and he was the general person in charge of Yang Xiaotao's hand-picking, he did not hesitate to arrange An Zhongsheng.

"Has the converter lining been inspected?"

Li Lei stepped forward, "It has been checked, and everything is in good condition." ”

"What about oxygen lances, pipes, water sources?"

"It's all ready, and we have prepared a spare replacement, which can be quickly replaced if something goes wrong."

Li Lei said, An Zhongsheng nodded.

"How's the fuel pack ready?"

"It's all ready, it's all old workers, the number of operations, there will be no problems."

Li Junming also replied with a notebook, "As long as you start, the hot air in the furnace can be used." ”

An Zhongsheng nodded.

"Laborer, take care of the liquid oxygen over there."

Xiao Guo nodded, "Don't worry, there won't be a problem over there." ”

Finally, he looked at Wang Hao, who came to assist, "Section Chief Wang, is the fire rescue in place?" ”

Wang Hao nodded, admiring a capable person like An Zhongsheng, "The two fire trucks and two ambulances of An Gong are already in place, and within two minutes, we are guaranteed to arrive at the scene." ”

"Good!"

After An Zhongsheng finished speaking, he looked at the people around him and spoke again, "Let's sort out the process again." ”

"First of all, the transportation of molten iron."

An Zhongsheng said here, and everyone below listened attentively.

This is the first time for a steel mill.

It is also the first new technology to be officially used in China.

Don't dare to be sloppy.

After a while, when An Zhongsheng finished talking about the precautions, a group of people in the distance had already walked up.

An Zhongsheng saw Yang Xiaotao leading the chief over, and hurriedly led someone to greet him.

"Mr. Yang, Chief"

An Zhongsheng stood aside, and Yang Xiaotao introduced to everyone, "Chief, this is the person in charge of this experiment, Comrade An Zhongsheng. ”

Huang Lao has heard of this person, and the Metallurgical Bureau has been pulling it intermittently, and now it seems that this person is coming, and he will not lose.

"Hello chief."

An Zhongsheng stepped forward to see it, and his expression was excited.

The last time I saw Xia Lao, this time he is a leader who is even older than Xia Lao.

Behind him, not to mention Li Lei, Li Junming and others, it is clear to look at the expressions on their faces.

Surrounded by the workers of the steel mill, they are deliberately dressed up for today's sake.

After several people met, under Yang Youning's arrangement, everyone began to climb the viewing platform.

The platform is just over a meter high, with only three rows of tables and chairs.

There was a red cloth at the top, and there were big characters written with a brush sticking to it, Yang Xiaotao looked at it, and it was, "Warmly welcome and guide the test test of the new oxygen top blowing technology." ’

belch

Easy to understand.

Yang Xiaotao found An Zhongsheng, "An Gong, ready?" ”

"Mr. Yang, everything is ready."

"That's good, don't be in a hurry when you wait, just come step by step."

"Yes, understood."

After talking to An Zhongsheng, Yang Xiaotao walked to the rostrum.

In the middle of the front row are Huang Laozhang and a few people, Yang Xiaotao and Liu Huaimin and Yang Youning were sitting on the edge of the first row, but when they came up, Huang Lao called him to his side and sat next to him and Xia Lao.

The workers of the steel mill below saw it and became more clear about Yang Xiaotao's status.

As for the people in the second row, most of them were leaders who came together, as well as comrades from the machine factory.

Chen Gong, as the host of this meeting, stood at the microphone and snatched Yang Youning's words.

Looking at the group of workers below, he spoke loudly.

"Leaders, leaders, comrades, good morning."

"On this sunny day"

After Chen Gong finished his opening remarks, he began to introduce the leaders attending the meeting.

After the introduction, he went straight to the point, and Huang Lao announced the start of the test run.

As Huang Lao's order was issued, An Zhongsheng looked serious and quickly commanded everyone to start acting.

"Attention to the hoisting group, the crane starts, the molten iron is ready to be filled, all departments pay attention to cooperation, repeat, all departments pay attention to cooperation"

"Roger."

"Understood!"

The sound fell, and under the tall tower in the distance, the big crane moved slowly, ready to receive the molten iron.

On the rostrum, everyone held binoculars and looked ahead.

From time to time, there were whispered exchanges and discussions.

Xia Lao looked at it for a while, and asked Yang Xiaotao on the side, "Why didn't you go to command this time?" ”

Yang Xiaotao put down the binoculars, "Leader, this is steelmaking, and I don't understand it." ”

"Anything else you don't understand?"

Huang Lao next to him smiled, and Yang Xiaotao hurriedly said after hearing this, "I really don't know much about this." ”

Several people laughed, and then listened to Yang Xiaotao's explanation, "The main thing is that there are too few books in this area to read." ”

Now everyone laughed even more happily.

Below, the overhead crane has been loaded with molten iron and began to move under the operation of the workers.

Everyone looked intently ahead, moving as the crane moved.

Finally, the crane came to the top of the boiler and stopped.

The worker in charge of observation wiped the sweat from his head, and after confirming the alignment, he waved the red flag in his hand.

An Zhongsheng was instructed, and then shouted, "Add molten iron." ”

Crash

On the rostrum in the distance, everyone saw a blazing torrent pouring into the boiler from the big crane, like boiling water exploding, and the molten iron could be seen splashing around.

It was not until the end, when all the cranes were reversed, that they moved away.

"It's not a big boiler."

Zhang Lao asked next to him, and Yang Xiaotao stretched his head forward and explained, "This was originally a small side furnace, and it can only be used one ton at a time." ”

Zhang Lao nodded and said no more.

Below, An Zhongsheng continued to shout, "Attention to each group, the oxygen gun is covered, and it is ready to start." ”

"Oxygen lance, oxygen lance attention, the pump should continue to work, repeat, it must continue to work."

Not far away, after inspecting the liquid oxygen tank, he instructed the workers around him to turn on the water pump.

In an instant, the water flows quickly in the reserved pipe inside the oxygen lance under the action of the water pump.

"Liquid oxygen ready."

Xiao Guo looked at the power pump on the ground again, and when he was ready, he needed to inject liquid oxygen into the oxygen lance, form a high pressure, and rush it into the boiler for stirring.

With An Zhongsheng's order, the lid with the oxygen gun slowly came to the top of the boiler, and after some confirmation, the lid slowly closed.

"Side door, close."

"Understood."

Click

The entire converter slowly closed in front of everyone's eyes, and the furnace, which was still glowing with yellow flames, instantly became quiet.

"Maintain the temperature, burn the group on, liquid oxygen, turn on."

An Zhongsheng roared loudly with almost all his strength, quickly and simply.

The workers fully grasped the gist of this.

The people in the combustion group pushed the coal and began to heat it, and the oxygen gun was turned on at this moment.

Liquid oxygen is driven by the power pump, which enters directly along the pipeline from the oxygen irrigation, and then passes through the nozzle to spray high-pressure liquid oxygen.

It's just that at this high temperature, the liquid oxygen has become high-purity oxygen when it comes into contact with the liquid surface, and then under the action of pressure, a vortex is formed at the nozzle, and the originally calm furnace suddenly sinks under this pressure, and then the surface becomes undulating, and the oxygen is integrated into the molten iron in this violent stirring, so that the whole molten pool is stirred.

Outside, An Zhongsheng nervously clenched the pen in his hand, for fear that there would be an accident at this time.

Li Junming and other people from the R&D department were watching nervously around, and various sounds in the furnace came from their ears.

They need to keep an eye on the boiler and record what they see as a first-hand source of research.

Five minutes passed.

An Zhongsheng's clenched palms were already sweating.

On the rostrum, everyone picked up binoculars from time to time to look at the boiler in front of them, although they couldn't see the situation inside, they still didn't want to put it down.

Ten minutes later.

Yang Xiaotao couldn't sit still, and this kind of waiting was very painful.

Watching the combustion team continue to transport coal, and watching the observers in front of them wipe the sweat from their foreheads from time to time, I always want to come forward and take a closer look.

Fifteen minutes.

Seeing that Yang Xiaotao was a little anxious, Xia Lao smiled on the side, "Can't sit still?" ”

"That's what, look at them, there's no hurry."

As he spoke, he pointed to the workers below.

I saw that the workers at the scene were not impatient, but some people sat on the ground and watched for a long time.

Looking left and right, many people had already picked up the enamel hall on the table and started to drink water.

Yang Youning, on the other side, explained something to Guan Zhiyong, and then saw Guan Zhiyong nodding and waving behind him, and saw a group of female workers walking up with a plate of apples and starting to distribute them one by one.

"This steelmaking is not something that can be done right away."

Huang Lao also explained on the side, "Sometimes it takes half a day to smelt a pot of molten steel, and it is not used at all if the time is short." ”

"And this requires the workers to observe carefully, and sometimes the smelting is uneven, the top is blue and white, and the bottom is still yellow, which means that it still has to be refined."
