Raw materials: What are the raw materials used for carbon production? In carbon production, the commonly used raw materials can be divided into two types: solid carbon raw materials and binders and impregnants. Solid carbon raw materials include petroleum coke, pitch coke, metallurgical coke, anthracite, natural graphite and graphite crushed, etc.; binders and impregnants include…
The generation mechanism of the slag circle: The temperature of the protective slag at the meniscus near the slag crystallizer is only 1200~1300°C, and so-called slag circles often appear during casting. The formation of the slag ring is caused by the adhesion of the sintered layer and the semi-molten layer of the mold slag in…
The effect of phosphorus on the properties of steel Phosphorus exists in the form of iron phosphide in steel, generally represented by [P]. Its specific effects on steel properties are: 1) It can deteriorate the welding performance of steel; 2) Reduce the plasticity and toughness of the steel, and make the steel cold brittle, that…
In actual production, in the specific steel processing stage, the defects that affect the quality of hot-rolled strip are explored and researched, and the technical problems and the ways to solve the problems are found, which will improve the overall production quality of the steel industry. Corresponding costs and improving the qualification rate have very…
