Just across the road from the wastewater treatment station is the power station and gas plant.

The power station is an important project in the steel industrial park, and in the completed plant, 250kw generators continuously transmit electricity to all corners of the industrial park. Next to the plant is a vacant land, where the second phase of the project will build a 16,000kw steam turbine generator set, and the strong power will provide sufficient power guarantee for the planned five-ton electric furnace steelmaking.

In the gas plant, a large cylindrical gas generator stands on a reinforced concrete base. This is to provide a steady stream of fuel for the upcoming open-hearth steelmaking and the hot-rolled steel plate after smelting, as well as gas for the canteen and gas cold storage of Taishan Iron and Steel.

Unlike the large-scale coke ovens of the Keelung Coking Plant, which have a 21st century technical level, this large-scale gas generator has a simple structure and is easy to operate, and it was directly purchased from the United Kingdom in this time and space. Although the team's mechanical port can make a more advanced gas generator, there are too many tasks for the mechanical port, so it is easier to purchase it directly.

After the coal is added to the furnace, it is ignited for dry distillation, and the air added from the bottom of the furnace reacts soundingly, that is, coal gas is generated. The tar produced during dry distillation is stored in a special tar tank and then transported to Keelung Coal Chemical Group for further refining.

The open-hearth workshop is the key target of the first phase of the steel plant, which is also located to the west of the plant.

The area of the No. 1 open-hearth workshop is 3,000 square meters, the roof structure 1 is completely welded with I-beam and triangular steel, the 6-meter-high factory column is made of reinforced concrete at one time, the lower part of the wall is a brick structure, the middle part is a prefabricated hanging board, the upper part is a half-open glass window, and the row crane beams are all special-shaped welded all-steel structures, which are specially sent from North America by Huafu Company.

Crane installation is a technical job, especially the installation of large gantry cranes is more difficult, and it is difficult for ordinary people to do it well. The open-hearth workshop is equipped with a 24-ton crane, which is much simpler.

Yesterday, the overpass track and trolley mechanism were all installed, and after He Ying's debugging, the track error was completely controlled within the specified range.

He Ying is the deputy general manager of the group and the director of Xizhi Machinery Factory. He Ying is a child of heavy steel, majoring in mechanical and automation control. Before the crossing, he was an engineer in Shougang Equipment and Structure Factory, and he was engaged in the production and installation of equipment in the steel plant.

Start installing electrical equipment today. The steam crane stretched out its long arm and lifted an electric motor steadily onto the steel structure platform of the overhead crane. He Ying took a few disciples and immediately connected the motor and began to install it.

The crane installation and commissioning area is close to the workshop gate, and there are safety officers at both ends to be responsible for guarding to prevent irrelevant personnel from entering the area by mistake and being hit by falling objects from high altitudes.

Huang Jiuyuan, the boss of the steel group, has been waiting at the scene to act as a safety supervisor.

At the beginning, when the Planning Commission designed an open-hearth workshop for a steel plant, some people thought that a 10-ton open-hearth furnace could directly pour steel ingots, and there was no need for a crane at all. Or he found Lin Youde, argued with reason, and added this equipment.

Huang Jiuyuan believes that the installation of overhead cranes in the open-hearth workshop can reduce the labor intensity of steelmaking workers, facilitate the charging of open-hearth furnaces, and make it easier to lift molten steel ladles.

“~！ ~！ The whistle sounded, and under He Ying's command, the crane began to try to move on the track.

At this time, Cheng Qing, the secretary general, took a comrade from the canteen, pushed a trolley into the workshop, and sent a large bucket of cool salt sugar water into the rest area of the workshop.

The entrance to the workshop is designated as a rest area, and there are many tables and chairs. The soldiers of the infrastructure construction regiment, the workers of the machinery factory, and the apprentices of Taiwan Iron and Steel Co., Ltd. have been working in the workshop for most of the day, and many people are tired and are sitting here to rest, and some people are holding the booklet "Open-hearth Steelmaking" and reviewing.

Seeing a large number of cool and cold drinks brought in, the people in the rest area "whooped" and all gathered around.

After half a morning, I sweated a lot in the workshop, and the salt and sugar water can not only replenish energy, but also replenish the lost salt, and the taste is also very good after being chilled.

People who were still working also stopped one after another and walked towards the rest area with water bottles.

"Go both sides, go both sides!"

Seeing that some people were in a hurry, they were about to walk under the big hook of the moving crane, Huang Jiuyuan immediately stopped them, "Don't walk under the crane!" ”

“~！”

He Ying was in a hurry, blew the whistle all of a sudden, and stopped the crane, "Where is the safety officer?" Where's the security officer? The hook is going to kill you! ”

The security officer in charge of the guard turned pale and ran from the rest area with a water bottle. He panted and explained to Huang Jiuyuan, "I saw the cold drink coming just now, so I left for two minutes, thinking it was nothing......

"Have you learned the safety manual?" Seeing that this cargo was still holding a broken kettle in his hand, Huang Jiuyuan was angry, "A second of negligence may lead to a fatal accident." ”

"I was wrong, I was wrong!" The security officer was stunned and said, "I stood all morning, and because I didn't encounter anything, I was paralyzed." ”

"By the time the accident happens, it's too late!" Huang Jiuyuan took out his notebook, "Your name?" ”

"Report to the instructor, my name is Shi Xiuchun." This guy's voice was lowered, "Instructor, can you give me a chance?" ”

Huang Jiuyuan glanced at Shi Xiuchun, "Today I will make a note of your mistakes, and next time I want to write down your merits." ”

"Yes, Instructor!" Shi Xiuchun stood upright, saluted, turned around and ran to continue the vigilance.

The test run went very smoothly, and He Ying was very happy.

Xiao Bailang's machinery factory has already produced two expansion machines, and Xizhi Machinery Factory can't always maintain steel mill equipment. He thought that if he could hold the production and installation of the overhead crane, it would be a great achievement.

"Everyone, hurry up and tighten the track nut completely!"

The steam crane that helped lift it was also moved out of the workshop, and the workers carried out the final sweep under the command of He Ying.

All right! The overhead crane is finished, and now it's up to Ge Tingwei. Huang Jiuyuan set his sights on the 10-ton twin-bed open-hearth furnace in the depths of the workshop.

This 10-ton twin hearth furnace is three meters high, the outer layer is a reinforced concrete structure wrapped in steel plates, and the furnace chamber is a groove made of refractory bricks, which is covered by a roof made of refractory bricks~.

There is a charging opening in the front wall of the open-hearth furnace from which the loader fills the charge. Close the door caused by the refractory bricks when smelting. At both ends of the furnace are stove heads, which are connected to gas pipes and oxygen pipes from the air separation plant.

At the top of the gas and oxygen pipes are a Bessemer-style spray gun, which Huafu North America bought from Bessemer.

Bessemer is a metallurgical expert of this era, and just applied for a patent for Bessemer's spray gun last year, he was approached by Huafu Company and specifically asked him to order.

Huang Jiuyuan smiled slightly, if Bessemer knew that our steelmaking equipment would definitely be eliminated and banned from the equipment he invented, would he still happily sell this Bessemer-style spray gun!

In the hearth, Ge Tingwei took six apprentices to carry out the final sweep of the lining of the hearth. He took these young men to build the hearth, brick by brick.

Ge Tingwei is the deputy general manager of the group and the director of the converter workshop, and he can drive a crane (overhead crane), forklift, and digging truck, but he can't drive a car. He was born in the armed police, has been engaged in furnace work for many years, and has always been meticulous in his work.

Building the hearth was actually the work of plasterers, and these apprentices had worked as plasterers before, and Ge Tingwei assigned them all to be his assistants.

It's just that these furnace repair assistants, the cultural knowledge of the high school has only been learned for a few days, and the drawings are very difficult to read. If it weren't for Ge Tingwei's hands-on efforts, the masonry of this hearth would have been out of shape a long time ago, and I don't know when it will be completed.

Ge Tingwei glanced at the size of the remaining gaps in the wall, "Two bricks of No. 3!" ”

"Two bricks of the third one!" Zhang Songbao turned his head and passed the word out.

Not far from the furnace, piles of refractory bricks were neatly stacked, and signs hung in front of each pile. Open-hearth hearth masonry is a type of masonry, and the composite bricks must be strictly numbered according to the group and issued according to the group.

The material clerk gently took out two refractory bricks from the No. 3 brick stacking area and passed them into the furnace one by one.

Ge Tingwei took a refractory brick from Zhang Songbao's hand, he didn't need to compare at all, he directly coated it with the mud used for the fortification, and put it in very easily. Then there was another No. 2 brick, which was coated with mud and put in it, just to fill in the gap.

Zhang Songbao said excitedly, "It's just right!" ”

With the help of the light, Ge Tingwei inspected the smelting room, furnace head, furnace wall, furnace bottom, etc., with sundries, brick chips, and mortar abounding.

He said calmly, "Now is the final stage, everyone be serious, let's tidy up this hearth from top to bottom." ”

The quality of the furnace finishing operation not only determines whether the appearance is good or not, but also has a great impact on the life of the furnace, so it must be carried out carefully.

The temporary equipment in the furnace, the remaining refractory materials, and the mud buckets used for the construction were all cleared out. Ge Tingwei led his disciples to carefully clean every brick gap with a brush, and he couldn't let go of any of the hook joints and expansion joints. Debris such as brick chips and mortar can cause various failures if they remain in the furnace, between the gaps in the bricks.

Ge Tingwei took his disciples and sorted out three times in a row, sweeping out all the sundries.

"That's it!" The disciples all smiled knowingly, as long as the door of the sludge chamber was sealed, the construction of the open-hearth furnace would be considered a complete success.

"Panic what!" Ge Tingwei stood in front of the stove, still a little uneasy.

In the past, he had only done the masonry of converters, and he had never touched open hearths. If there is a slight mistake in the masonry, it may cause pores and sand holes in the lining of the furnace, which will bring hidden dangers to the operation of the open-hearth furnace.

"Flashlight!" The lighting system has been withdrawn, and if you go in to check it out, you can only use a flashlight.

Zhang Songbao handed over the flashlight, his eyes were a little puzzled, "Instructor? ”

"You go rest first, and I'll go in and have a look!" Ge Tingwei flashed the flashlight and got into the furnace shell again.

The roof of the furnace, the flue system, the front and rear walls, the riser of the furnace head, the sediment chamber..., Ge Tingwei checked the situation of the masonry one by one. For key parts such as the bottom of the furnace and the taphole, he shook first and then vibrate, and tested the brick joints one by one.

After repeated inspections, it was finally confirmed that there was no problem, and Ge Tingwei breathed a sigh of relief and easily drilled out of the furnace.

"Instructor!" The disciples gathered around at once.

Huang Jiuyuan handed over a cold drink and asked with concern, "Can the door be closed?" ”

Ge Tingwei lazily took off the big mask covering his face, and drank a big mouthful of salt sugar water, "Seal the door!" ”

Under He Ying's command, the crane made a "toot" sound, slowly moved over, and put the steel door crane down. The crowd worked hard to build up the door frame and finally install the furnace door.

The open-hearth masonry was completed, and there was a round of warm applause in the workshop
