Abstract

Ferro-coke is an iron-containing novel kind of coke, to clarify its behavior of CO2 gasification under Zn recirculating condition in the blast furnace is very important for its practical application in BF production. In this paper, the weight loss of ferro-coke was determined with a thermogravimetric balance, the variation in exhaust gas composition at several different temperatures were measured with a gas analyzer. The results revealed that zinc has catalytic effect on CO2 gasification in respect to the decrease in starting gasification temperature and the increase of burning-off degree. And also for ferro-coke, the reactivity increased while the post-reaction strength decreased along with the zinc content increasing. Generally speaking, the impact of zinc on ferro-coke thermal properties is weaker than potassium.
