Siheyuan: Start at level 60, beat up all the animals

"Xiao Li... Engineer Li, how did you modify this top and bottom blown converter? How did you control the temperature? How did you control the time of steel production?"

"Yes, you said that the temperature of the molten steel can reach 1600 degrees. How much energy does that require? How do you get the materials for the furnace?"

"Also, your steel production speed is simply amazing! You can produce a furnace in just over ten minutes. How many times more efficient is this than the traditional open-hearth furnace?"

The experts spoke one after another, asked a series of questions, and stared at Li Yang eagerly, wishing they could dig out his brain and have a look at it immediately.

But Li Yang seemed calm and oblivious to all the noise.

He smiled and said slowly: "Dear leaders and experts, don't get excited.

In fact, the principle of this top-bottom combined blowing converter is very simple. To put it simply, it uses a combination of pure oxygen top blowing and oxygen-enriched bottom blowing to greatly improve steelmaking efficiency and molten steel quality.

As he spoke, Li Yang took out a stack of drawings and spread them out in front of everyone.

There were all kinds of lines and numbers drawn on it, with some professional terms marked next to them.

"You see, the key to the transformation lies here." Li Yang pointed to a certain place on the drawing and explained.

"First, we need to install six oxygen lances on the top of the furnace, using Lava nozzles with a flow rate of 6 cubic meters per minute. They can spray industrial oxygen with a purity of up to 200% into the molten steel at twice the speed of sound, completing decarbonization and desulfurization in an instant."

Everyone was stunned and stared in amazement, like primary school students listening to a lecture.

Just a few words outline an incredible scene.

"At the same time, we will install 12 oxygen-enriched gas nozzles at the bottom of the furnace, which will introduce 800 cubic meters of gas and 1200 cubic meters of industrial oxygen per minute to form a strong bottom blowing force, which can not only greatly increase the temperature of the molten steel, but also make the decarbonization and sulfurization reaction more thorough."

Li Yang pointed at another drawing, his eyes sharp, as if he could see through the secrets of steel.

The voice was sonorous and powerful, and every word was firm and unwavering.

"On this basis, we also need to upgrade the refractory materials of the furnace body, select high-alumina bricks and magnesia-carbon bricks to replace the original silica bricks, and increase the maximum operating temperature of the furnace lining and furnace cover from 1400 degrees to 1650 degrees to ensure that the furnace will not burn through at ultra-high temperatures."

"Finally, to realize the automation and continuous production of the top and bottom combined blowing converter, we also need to develop an automatic adjustment system for the bottom blowing gas, a precise control system for the oxygen flow, a program control system for the steel tapping time and sequence, etc. All of these require a lot of manpower and material resources to tackle the problem."

Li Yang spoke eloquently, his face shining with a thirst for knowledge and enterprising spirit.

His ideas were clear and well-organized, and everyone present was enlightened as if by his words.

Deputy Minister Zhao and the experts looked at each other in bewilderment. Only then did they realize that they not only had advanced ideas, but also had meticulous designs and thorough considerations. No wonder they could achieve such amazing results!

Thinking of this, they felt a sense of admiration for Li Yang.

He is just a young man, but he has already stood at the forefront of the times and led the revolution of the steel industry. This courage and vision are truly extraordinary!

Deputy Minister Zhao could no longer contain his excitement. He slapped the table and said loudly: "Comrade Li Yang, your design is so ingenious! Our factory must study and understand this drawing and information carefully, and strive to promote the top-bottom double-blowing technology nationwide as soon as possible! Don't worry, the factory will give you the greatest support and ensure that this revolutionary initiative will become an eternal monument!"

After that, he turned around and told the people around him: "What are you still standing there for? Hurry up and prepare the car to transport all these valuable data back to the factory! From now on, we will launch a vigorous technological innovation and let the fire of top-down and bottom-up burning on the national steel front!"

The entourage dispersed at the command, quickly put away the drawings, and carefully carried them onto the truck.

Li Yang's technical information has become a national treasure hidden in the bottom of the box. If there is any mistake, it will be talked about for the rest of your life.

Looking at the busy figures of the crowd, Li Yang smiled with satisfaction.

He knew that the seeds of top-bottom blowing had been sown in fertile soil, and it would not be long before they would branch out and become the mainstay of the country's industry.

At this moment, the door of the steelmaking workshop was pushed open again, and a tall and majestic figure in military uniform strode in.

"dad!"

Lin Xiaoxiao's surprised voice was the first to sound.

She dropped the work in her hands, ran to the man and hugged his arm.

This is none other than Lin Xiaoxiao's father - General Lin!

The purpose of his trip was also to investigate the power of the top and bottom blown converter.

As the head of the military industry, how could General Lin not attach importance to this weapon that could bring about a major breakthrough in national defense construction?

"Okay, Xiaoxiao, how do you feel about your internship at the steel mill these days?"

General Lin touched his daughter's head lovingly, his eyes passed over her shoulder and fell on the converter not far away.

"Dad, you don't know how many big things have happened during this period! Especially Li Yang, he has created a miracle!"

Lin Xiaoxiao said with great joy, unable to conceal her inner excitement.

She held her father's hand and talked endlessly about the advantages of the top-bottom double-blown converter: the steelmaking time is shortened, the quality of molten steel is greatly improved, and the energy consumption is reduced by 30%... Each one of them is amazing!

General Lin nodded frequently and praised repeatedly.

The look he gave his daughter gradually became more meaningful.

"Xiaoxiao, do you admire Li Yang very much?"

Hearing the sarcasm in her father's words, Lin Xiaoxiao couldn't help but blush.

She glared at him in reproach and whispered, "Dad, don't talk nonsense! Comrade Li Yang and I have a serious revolutionary friendship! How could it be like what you think..."

General Lin laughed and scratched his daughter's nose affectionately.

He knew that his daughter always had a unique eye for judging people. Since she praised Li Yang highly, this young man must be extraordinary.

"Alright, alright, Xiaoxiao, you're shy, how could your father not know? Don't worry, when it comes to Deputy Section Chief Li's ability, your father knows it. But now, we have to hurry up and quickly get the top and bottom double blowing technology, so that we can go back and prepare for the military industry!"

General Lin said this seriously, his eyes were as sharp as torches, revealing a strong character.

He walked quickly to Li Yang and held his hand tightly.

"Comrade Li Yang, this new technology you have developed will not only have great potential in the civilian field, but will also play a significant role in promoting the national defense industry. On behalf of the military industry, I sincerely hope that you can share some of the technical information with us, so that we can work together to contribute to the country's steel industry!"

General Lin's words were powerful and decisive.

Upon hearing this, Li Yang was stunned at first, then a look of joy appeared on his face.
