Heat Resistant Refractory Raw Materials Brown Fused Alumina Tilting Furnace

Heat Resistant Refractory Raw Materials Brown Fused Alumina Tilting Furnace

 

Description:

 

Brown Fused Alumina is fused in the electric-arc furnace under the high temperature of above 2250°C with high quality bauxite as raw material and matched by the carbon material and scrap iron .The degree of refractory is more than 1850°C.

 

Production process: sorting of the raw materials→electrolytic smelting→crushing→magnetic separation→filter→physical and chemical testing→packing→warehousing
