High Quality and Performance Low Cement Refractory Castable

The cement content of the traditional common refractory castable is as high as 10 ~ 30%, while the matrix of low cement and ultra-low cement is prepared by replacing part or most of the cement with ultra-fine powder (particle size less than 5um) with a small amount of dispersant (water reducer) and a certain amount of delayed retarder.

Product Function

Ferrosilicon furnace is an industrial electric furnace that consumes a lot of power and is a type of submerged arc furnace. Ferrosilicon furnace includes furnace shell, furnace cover, furnace lining, short net, water cooling system, smoke exhaust system, dust removal system, electrode shell, electrode pressure release and lifting system, loading and unloading system, controller, burn-through device, hydraulic system, transformer And various electrical equipment, etc., the use of refractory materials is also quite demanding.



In 2006, Our factory was founded in Yuzhou, the raw material base.High bauxite ore is a finely divided colloidal mixture composed of aluminum hydroxides and various ratios. High-alumina bauxite in the refractory industry usually refers to bauxite ore with a calcined Al₂O₃ content greater than 48% and a low Fe₂O₃ content.
