How steel is made is summarized in 10 parts

Why 10 parts, I'll summarize:

1.Mining or beneficiation 2Sintered or pelletized 3Blast furnace ironmaking 4Molten iron pretreatment 5Converter steelmaking 6Outside the furnace refining 7Continuous casting 8Heating furnace 9Roughing mill 10 finishing mills.

The second chapter of the second part of "How Steel is Made" summarizes the news that caused a sensation in Paul's town, and that some Bolsheviks had appeared. The rich people fled, the friends came, and the people got the allotments, but soon, the friends retreated one by one, and the enemies came, and they demanded that all the masses pay **. The rich are back.

Brother Bao met the assembler Zhu Helai, and became a good friend, Zhu Helai taught Paul a set of British boxing techniques, and often told Paul some revolutionary principles, telling Paul that some people should really fight. Paul stole ** from a neighbor's house and hid it on the beams of the house, but when he searched it, he did not find it.

Paul and his crew were transferred to build the railroad. The working conditions of the Zhuye Tanlu team were very difficult, and the harassment and disease of the bandits, as well as starvation, threatened Paul and his comrades. Paul worked selflessly.

In the cold winter, people are still working hard in the ice and snow. Once at the station, Paul also met Tonya.

When the railroad was finally completed as scheduled, Lu Zhuhe was deeply moved by their revolutionary enthusiasm and said that steel was made in this way. He also gave Paul a gun, but soon after, Paul fell ill.

The above is my understanding, I hope it can help you.

How Steel is Made is a book written by the Soviet writer N.I. Ostrovsky about the development of Soviet industry. The following content summarizes the refining process of steel in ** into five parts.

1. Blast furnace ironmaking. Pure iron is made by heating basic ironmaking products such as pig iron and cast iron to soften and collapse, and removing a variety of impurities such as magnesium and sulfur and silicon through blast furnace technology. This is the first step in the manufacture of high-grade steel.

2. Converter steelmaking. The iron obtained from the blast furnace is melted, and scrap steel is continuously added to the converter, and the impurities in the molten iron are removed by using oxides such as magnesium and calcium, and finally high-quality steel materials are obtained.

3. Continuous casting molding. By pouring the molten steel directly into the mold of the caster, it is quickly cooled and turned into steel billets, so as to simplify the process of steel production and improve the quality of steel forming.

Fourth, rolling into shape. Steel is heated from the billet state and turned into products of various shapes and sizes through the corresponding rolling process to meet the needs of different industries in various specifications of steel and iron products.

5. Surface treatment. It means that before the steel material is made into the final product, it needs to go through a series of surface treatment processes such as rust prevention, painting, and drying to reduce the corrosiveness of the steel material and increase the quality of steel products for special purposes such as plating and thermal evaporation targets.

In short, steel refining is a complex production process, which needs to go through multiple links and processes to achieve the manufacture of various steel products, and ensure product quality and specification requirements under the premise of safety, efficiency and environmental protection. <>

For the first city timber, a railway was to be built in three months. So Paul and the members of the Gongqing Filial Piety Bench were transferred to build the railway.

The working conditions of the road construction team were very difficult, and the harassment of armed bandits, disease, and starvation threatened Paul and his comrades. Paul worked so selflessly that even his boots were rotten. In the cold winter, people are still working hard in the ice and snow.

The workers vowed to build the railway on time. Once at the station, Paul also met Tonya.

When the railway was finally built as scheduled, Zhu Helai was deeply moved by their revolutionary enthusiasm and said, "This is how steel is made of clear beams." He also gave Paul a gun. But soon after, Paul fell ill.
