Product Description

The agglomeration method uses an open electric furnace that can move on tracks and the upper section of the furnace body is detachable, and carbon is used as the reducing agent. The mixed charge composed of refined tungsten ore, pitch coke (or petroleum coke) and slagging agent (bauxite) is added to the furnace in batches. The metal refined in the furnace is generally viscous. As the thickness increases, the lower part gradually solidification. When the furnace is full, stop the furnace, pull out the furnace body, and remove the upper section of the furnace body to allow the agglomerates to condense. Then take out the clot, crush and finish it; pick out the edges, slag and unqualified parts and return them to the furnace for remelting.

Ferro Silicon used coke quartz(or silica)as raw material is made by electric furnace, because silicon and oxygen are easily
compound into SiO2, the Ferro Silicon is often used as deoxidizer in steeling. It also can be used as a suspended phase in the mineral processing industry and coating for welding electrodes in the electrode manufacturing. According to the content of Silicon, this product can be divided into FeSi with the Si content: 75%,72%,70%,65%,60%,45%.
