Daqin: Check in at the beginning of 18 and ask Zulong to abdicate

"Is everything clear?" Ying Zigao imparted the salt industry production technology to the salt industry officials without reservation and patience.

Then he asked seriously.

"Your Majesty, all the ministers are clear." The salt industry official said hurriedly.

"This is the flow chart of the new salt production technology drawn by myself."

Ying Zigao nodded, handed a roll of silk cloth to the eunuch, and said, "This drawing clearly shows every step of salt production!

Take it with you to the East China Sea Salt Fields, and teach the local artisans to build the salt fields for me as soon as possible! "

"Wei Chen understands!" The sales official hurriedly took the silk cloth and said loudly!

"From now on, you are the supervisor of Daqin's Donghai Salt Factory! An official who is more than two thousand stones!"

Ying Zigao then said loudly: "Let go and do it! As long as the Donghai Salt Field can be successfully completed and put into operation on time, you will make great contributions to the imperial court! I will reward you well!"

"Thank you, Your Majesty!"

The salt industry official hastily agreed loudly.

Under Ying Zigao's personal care and guidance, and the huge energy of the court, the government-run iron smelting workshop was successfully completed in just one month!
On the day of commissioning, Ying Zigao brought Dongfang Bubai, Yuhuatian, Liu Bowen and other important court officials to attend the commissioning ceremony in person.

Ying Zigao asked the official in charge with a serious face: "How is the preparation for production going?"

"Your Majesty, according to the operating procedures you have formulated, we have organized the craftsmen to conduct simulation exercises eight times, and they have all reached proficiency in operation, so as to ensure that there will be no operational errors during the ironmaking process!"

The official in charge of the iron-making workshop said hastily.

Ying Zigao then asked, "What about the equipment? Have you checked everything carefully?"

"Don't worry, Your Majesty, I have done sufficient inspection work in strict accordance with the process regulations formulated by Your Majesty!"

The official in charge quickly said: "The blast furnace has been baked at low temperature for eight days, and after careful inspection, there is no suspicious crack;

Pulley blocks, flywheels, water wheel bearings, pulleys, piston bellows and other moving parts, after the workers simulated drills, they tried to run idling four times, and the conditions were very good every time. A little blocking! "

"These few days." Ying Zigao nodded and said.

Immediately, the commencement ceremony was held on time.

Ying Zigao gave a concise speech at the ceremony.Emphasis is placed on the importance of iron production to the national economy and people's livelihood of the Great Qin Dynasty.

Immediately afterwards, he announced loudly: "Light it up!"

With an order, the officials of the Ministry of Industry came to Ying Zigao holding a torch, bowed and saluted, and said, "Your Majesty, this ironmaking workshop, especially this blast furnace, was built under your personal guidance and care. .

This is the first fire, I should invite you to order it! "

"You are the heroes of this iron workshop!"

Ying Zigao laughed loudly and said nonchalantly, "You, the official in charge, will order some!"

"Thank you, Your Majesty!"

The official in charge secretly became excited, and hurriedly agreed to order to pick up the turpentine torch and throw it into the blast furnace through the tap hole at the bottom.

After the groundbreaking ceremony, Ying Zigao left the ironmaking site and had lunch with the officials in charge.

"Your Majesty, after we finish our meal, it's time to go back."

While eating, Yu Huatian said seriously: "The imperial court still has many things to deal with."

"That's not in a hurry." Ying Zigao said with a smile, "I still have to wait to see the first furnace of molten iron come out!"

Hearing this, Yuhuatian and Liu Bowen couldn't help but frown.

"Your Majesty, it took a lot of time to smelt iron!"

Yu Huatian hurriedly said: "It will take at least one day and one night!"

"Yes, Your Majesty!" The official in charge of the iron smelting workshop also said hastily: "What the Prime Minister said is right. It will take a day and a night at the fastest to smelt molten iron from ore!"

"Your Majesty, let's go back to the palace after eating."

Liu Bowen also hurriedly said: "The officials in charge of the iron-making workshop are very serious and responsible. You can rest assured that you will leave the iron-making to them!"

"It's not that I'm worried about them, I really want to see this first batch of molten iron come out!"

Ying Zigao said confidently: "The current production technology is new, and it only takes two hours for the first batch of molten iron to come out!"

Seeing Ying Zigao's confident expression, Yu Huatian, Liu Bowen, and the officials from the Ministry of Industry still didn't believe it in their hearts.

But he didn't dare to question it face to face.He had no choice but to promise and start eating properly.

The lunch lasted for more than an hour, and when it was about to end, the responsible officials of the on-site management rushed to the banquet hall!

"How did you come?"

Seeing the little official sweating profusely, his official uniform covered in dust, and sweaty all over, the officials from the Ministry of Industry couldn't help but frown!

"It's too fast! My lord, go and see, it's already turned into molten iron!"

The little official said excitedly!

"Molten iron has been trained so quickly?" The officials of the Ministry of Industry couldn't help being surprised!
You know, iron smelting in the past was also a government-run workshop, and it took at least a day and a night to smelt iron ore into molten iron!

Now, in only two hours, the iron ore has not been heated red before, and it has been smelted into water here!

Ying Zigao smiled confidently.His iron and steel smelting technology is at the level of Song Dynasty technology.

I made improvements with reference to modern smelting technology, adopted hydraulic blowers, replaced charcoal with coke, and added regenerators and preheating air devices!

The efficiency of smelting will naturally be greatly improved!
"The first furnace of molten iron has been trained?"

Ying Zigao smiled confidently and said, "I want to go and see for myself!"

At this time, in the iron smelting workshop, the smelting craftsman observed carefully from the observation port on the side of the blast furnace, and shouted to the big craftsman: "Master, the molten iron has gathered at the bottom of the furnace, and the color is as red as an orange, and the red is shining brightly." !"

The master craftsman immediately waved the command flag: "Open the furnace and cast iron!"

The craftsman in front of the furnace, wearing heavy linen overalls, quickly opened the blast furnace door, and the orange-red molten iron immediately rushed out like magma.

The flowing molten iron flowed into the prepared casting molds along the prefabricated grooves, and quickly cast large iron ingots one by one!

At this time, the ministers and entourage brought by Ying Zigao have also arrived at the ironworks!
"Your Majesty, 200 large iron ingots have been cast from this blast furnace pig iron!"

Yuhuatian counted the cast iron ingots carefully, and he couldn't help being surprised!
"How much does this iron ingot weigh?" Ying Zigao asked with great interest.

"Your Majesty, each iron ingot weighs 300 catties!" the Ministry of Industry official said hastily.

Hearing this, Yuhuatian, Liu Bowen and all the ministers, as well as the craftsmen and officials in charge of the scene were shocked!
The largest iron-smelting furnace before the Great Qin Dynasty only produced 3000 catties of iron in one furnace, but the ones placed in the ground weighed more than 6 catties!
