Quick - drying castable for iron trough/Used for main groove of blast furnace/Low melting rate/Resistance to erosion
Product description:
This series of products are made of corundum,high quality bauxite and silicon carbide incorporated with appropriate drying agent. These castables overcome the shortcomings of ramming mixes such as short service life, frequent maintenance, high materials consumpiton and high labor intensity, as well as overcome the shortcomings of normal castables such as long time firing. They have been widely applied at blast furnace body and waist mouth and bottom.
