How steel is made, how steel is made

Introduction: This book tells the story of the protagonist Paul Kochagin's journey from a poor boy struggling at the bottom of society to a proletarian revolutionary fighter who has fought all his life for the cause of the motherland and the people. The young Paul used to be a clerk and was bullied; stole a pistol from the Germans and was imprisoned for saving Zhu Helai; tossing and turning on the battlefield filled with gunpowder, struggling on the death line many times; After the victory of the revolution, he devoted all his body and mind to the construction of the people......In this process, Paul showed the noble character of perseverance, courage and selfless dedication of a true proletarian revolutionary fighter, he gave his precious youth to the party and the people, and bravely took up the pen to serve the people even though he was paralyzed.

Paul's spirit is an eternal banner, and Paul's deeds and character are an example for every young person in the 21st century to learn from.

How Steel Is Made depicts Paul Kochagin's life as the son of an ordinary worker, who lived through the rigors of the First World War, the October Revolution, the Civil War, and the recovery of the national economy, transforming the spontaneous rebellion against the old life into a conscious class will. Paul's growth is not "the self-development of character", but, as the author recalls his own life: "Steel is a ...... made in a raging fire and a sudden cooling."Our generation has also been tempered through struggle and arduous trials.

Paul's heroism was the rational sincerity of the early Bolsheviks, and individual values and collective causes were in conceptual harmony. Not only does he portray this protagonist through one dilemma after another, but he also expresses this sincerity through stirring monologues and thought-provoking aphorisms. Once, when Paul came to the martyr's tomb to mourn his comrades who died for the revolution, he silently thought:

The most precious thing for a human being is life. It is given to us only once. This is how a person's life should be lived:

When he looks back, he does not regret that he wasted his time, nor is he ashamed of his inaction. So that at the moment of his death, he could say: "I have devoted my whole life and all my energies to the most glorious cause of all—the struggle for the liberation of mankind."

The love entanglement with Tonya, the friendship with Lida, and the sincere feelings for Daya also show the purity of Paul's spiritual world and the special qualities of the character.

The author uses himself as the prototype of the protagonist, but it is not autobiographical. He said; "My long story is first and foremost a work of art, and in this long story I use fictional rights. The author's intention was "to create in the work a typology, a typology of the young revolutionaries of our time, the epoch of the proletarian revolution." ”

Are you asking about that book or real steelmaking?

Iron and steel is made from mineral raw materials such as ore, coke, and coal through smelting, solidification, refining and other processes.

1. Smelting: Mineral raw materials such as ore, coke, and coal are put into the blast furnace to rise, heated and smelted, so that the chemical reaction occurs, and the mineral raw materials are converted into molten iron. The raw materials used in steel refining are scrap iron or iron ore, and scrap iron is obtained from the first, while iron ore comes from nature, and the refining methods of different raw materials are different.

2. Coagulation: The molten iron is solidified to make it solidify into iron ingots. The slag discharge or slag removal operation taken in the smelting process according to different smelting conditions and purposes in the electric arc furnace steelmaking.

If the single slag method is used for smelting, the oxidized slag must be picked at the end of oxidation; When the double slag method is used to make the reducing slag, the original oxidized slag must be completely released to prevent phosphorus return.

3. Refining: The iron ingot is refined to remove the impurities in it and make it steel. This process is to purify the molten steel obtained from electric furnace (or blast furnace) steelmaking, remove impurities, and obtain relatively pure molten steel.

The continuous casting machine pours the steel billet, the molten steel refined through the above process, the billet is obtained after pouring into the casting mold to cool and solidify, the large-scale production of steel in modern industry generally uses the continuous casting machine, which can continuously pour the molten steel and continuously output the billet, and the steelmaking process has been completed at this time.

4. Processing: The steel is processed, and the billet obtained is rolled, drawn or machined according to its use to obtain various shapes of steel, or made into a variety of steel products of different specifications. At this time, Heshu steel is a commonly used steel raw material in the market.
