The scrap steel crusher is a kind of crushing machine used to produce scrap steel. It is mainly used for scrapping cars, scrapping home appliances and light and thin scrap steel. The main body shell is made of extra-thick steel plate, and the inner lining is high manganese cast steel, which can be replaced. The materials are neat in shape and similar in specifications; they have a higher heap specific gravity; there are fewer attachments; and the purity is higher. The use of crushed steel for iron and steel smelting has the following advantages: high yield; stable chemical composition of molten steel and low sulfur and phosphorus content; shortened smelting cycle; longer furnace lining life; reduced air pollution and slag; electricity consumption per ton of molten steel The amount is reduced.
