Product usage
Mainly used in producing common magnesite brick, magnesite aluminum brick, magnesite chrome brick, gunning mix, hot patching mix for converter and EAF ect .
Product Advantage
Our factory produce the products of the Dead-burned magnesite are selected natural magnesite, it is produced by mine-selecting, purifying, calcimine in shaft kiln. It is an ideal material for unshaped refractory material, the final products are used in open hearth furnace, electric furnace bottom and furnace's lining tamping.
