Research on Baking Preheating Technology of Ladle and Scrap
This paper studies the problem that the temperature of molten iron drops too much after molten iron is added to scrap and the temperature is low after molten iron reaches steelmaking,and expounds the preheating and baking system of molten iron and scrap independently developed by Shaogang.Through the application of this technical achievement,the loss of molten iron energy caused by the addition of iron ladle and scrap steel has been eliminated,the average temperature of molten iron in steelmaking has been increased by 22 ℃,the ratio of iron to steel has been reduced to 750 kg/t,and the annual economic benefit has reached more than 5 million yuan.
