Abstract

The invention relates to the field of metallurgy and particularly relates to an iron ore cooled agglomerated pellet binder comprising calcium oxide, silicon dioxide, pottery clay and water glass. The binder disclosed by the invention is economic and practical and has high commercial values; and the binder is applied to the field of metallurgy and has the benefits that raw materials are saved and enterprise benefit is increased.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a binder for iron ore powder. Background technique [0002] China is a big steel producing country in the world. According to statistics, my country's annual steel output has reached 350 million tons. However, the annual output of associated secondary iron-containing resources (such as sintering dust, returning ore, blast furnace dust, steelmaking converter sludge, etc.) is also amazing, with more than 10 million tons. The iron content is as high as about 45%. In order to extract this part of ore iron, some enterprises return part of the iron-containing dust to the sintering plant for utilization, but because the material is extremely difficult to form with ordinary binders, the ball forming performance, sinter quality, and air permeability cannot reach the blast furnace According to the application requirements, it can only be put into the waste yard for accumulation in the end, whic...
