On the rostrum, everyone held telescopes and stared ahead.

From time to time, someone would communicate and discuss in a low voice.

Xia Lao watched for a while and asked Yang Xiaotao, "Why don't you take command this time?"

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

"Is there anything else you don't understand?"

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

Several people laughed, and then listened to Yang Xiaotao's explanation, "The main reason is that there are too few books in this field and there are not enough books to read."

Now everyone laughed even more happily.

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

Everyone was looking ahead intently, moving with the movement of the big crane.

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

The worker responsible for the observation wiped the sweat from his head, confirmed the alignment, and waved the red flag in his hand.

An Zhongsheng received the instruction and then shouted, "Add molten iron."

Wow

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

It was not until finally that all the overhead cranes were dumped in and moved away.

"This boiler is not big."

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

Mr. Zhang nodded and said no more.

Below, An Zhongsheng continued to shout, "Attention, all groups, the oxygen guns are blocked and ready to start."

"Oxygen gun, oxygen gun, pay attention, the water pump must continue to work, repeat, must continue to work..."

Not far away, after inspecting the liquid oxygen tank, Pang Guo instructed the workers around him to start the water pump.

Under the action of the water pump, the instantaneous water flow quickly flows in the reserved pipe inside the oxygen gun.

"Liquid oxygen is ready."

Pang Guo looked at the power pump on the ground again. He would need it later to pump the liquid oxygen into the oxygen gun to form high pressure and rush it into the boiler for stirring.

As An Zhongsheng's order was issued, the lid with the oxygen gun slowly came to the top of the boiler. After another confirmation, the furnace lid slowly closed.

"Side door, close."

"clear."

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

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

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

The workers fully understand the essentials.

The people in the combustion team pushed the coal and started heating it, and the oxygen gun was turned on at this moment.

Driven by the power pump, liquid oxygen enters directly from the oxygen tank along the pipeline, and then passes through the nozzle to spray out high-pressure liquid oxygen.

It's just that at this high temperature, the liquid oxygen has turned into high-purity oxygen when it comes into contact with the liquid surface. Then under the action of pressure, a vortex is formed at the nozzle. The originally calm furnace suddenly dents under this pressure, and then the surface becomes

The waves undulate, and oxygen blends into the molten iron during this violent stirring, causing the entire molten pool to stir.

Outside, An Zhongsheng nervously clenched the pen in his hand, for fear of an accident happening at this time.

Li Junming and other people in the R&D department were all watching nervously, and various sounds from the furnace could be heard in their ears.

They need to pay attention to the movement of the boiler at all times and record what they see as first-hand information for research.

Five minutes passed.

An Zhongsheng's clenched palms were already sweating.

On the podium, everyone picked up their binoculars from time to time and looked at the boiler in front of them. Although they couldn't see what was going on inside, they still didn't want to put it down.

ten minutes later.

Yang Xiaotao could no longer sit still. This kind of waiting was very painful.

Watching the combustion team continuously transporting coal, watching the observers in front wiping sweat from their foreheads from time to time, I always wanted to step forward and take a closer look.

fifteen minutes.

Seeing that Yang Xiaotao was a little anxious, Mr. Xia smiled and said, "Can't you sit still?"

"Where are you? Look at them, they are not in a hurry."

As he spoke, he pointed to the workers below.

I saw that the workers on site were not impatient. Instead, some people were sitting on the ground and watching at leisure.

Looking around again, many people had already picked up the enamel bowl on the table and started drinking water.

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

"This steelmaking cannot be completed immediately."

Mr. Huang was also explaining on the side, "Sometimes it takes more than half a day to smelt a pot of molten steel. If the time is short, it is useless."
Chapter completed!
