Abstract
Description
Coal injection method of mobile electric furnace using anthracite instead of coke in pyroelectric furnace smelting technical field The invention relates to a technology and equipment in the smelting and production of pyrothermal electric furnaces, in particular to a coal injection method for a mobile electric furnace in which anthracite is used instead of coke in the pyroelectric furnace smelting. Background technique Pyrometallurgy refers to various operations that use fuel, electric energy or other energy sources to generate high temperatures, and use metallurgical furnaces at high temperatures to separate valuable metals from a large number of gangues in concentrates. Also known as pyrometallurgy, it is a metallurgical process that uses high temperature to extract metals or metal compounds from ores, and is the main method of metallurgy. In this process, no aqueous solution participates in the reaction, so it is also called dry metallurgy. It is mainly used in iron and...
