Experimental Study of Sintering Characteristics and Ore Blending of Laos'Ore Powder
Affected by the continuous increase in the price of bulk raw materials,iron and steel enterprises have high production costs,and their profit margins have been continuously compressed.Developing cost-effective minerals to replace high-priced sintering raw materials and seeking a more economical material structure have become a way to promote enterprises to reduce costs and increase efficiency.As a kind of hematite with low grade,low silicon and high burning loss,Laos'ore powder has a larger particle size than common ore,which is beneficial to improve the permeability of the mixture after mixing.However,due to the poor liquid-phase fluidity of Laos'ore powder,the vertical sintering speed in the sintering process is too fast,which adversely affects the yield of the sintering and the strength of the finished ore in the hot and cold states.The use of Laos'ore powder in sintering can improve the economy of ore blending.It is recommended to use it with ore powder with fine particle size and good liquid-phase flow performance.
