CARBON REDUCERS FOR THE PROCESSES OF FERROALLOY PRODUCTION IN THE ELECTRIC FURNACE

摘要

The article presents the requirements regarding the carbon reducers used in the processes of melting ferroalloys by means of electrothermal methods. The quality and the constancy of the carbon reducers' properties have a significant impact on the course of electrothermal processes of melting ferroalloys. The influence is particularly significant in the commonly used continuous processes. The paper describes the properties of such carbon reducers as: metallurgical coke, hard coal, semi-coke, petroleum coke and charcoal. The paper also presents the influence of the reducers' chemical composition and granulation on the process of melting ferroalloys in electric furnaces. The following properties of the above mentioned reducers were investigated: electric resistance, reactivity and durability.
