Probing of Iron Ore “Plus Calcium Oxide Grade"

Abstract:

Article Preview

A new concept, “Plus Calcium Oxide Grade”, was put forward, which is the very mass percentage of iron element when Calcium Oxide addition fulfills the need of the basicity of the blast furnace slag. The “Plus Calcium Oxide Grade” and “Minus Calcium Oxide Grade” of iron ore, iron concentrate, sinter and pellet was calculated, analyzed and also compared. The results showed that: the Plus Calcium Oxide Grade can reflect the smelting value more objectively and reasonably, while the basic grade and “Minus Calcium Oxide Grade” can not. So it is suggested that the concept of “Plus Calcium Oxide Grade” can be brought into the iron ore dealing and using, and also into the area of iron concentrate, sinter, pellet and furnace mixture.
