Refractory Raw Materials-Sintered Spinel Materials

Product Description:

It's made of industrial alumina and high purity caustic magnesia powder as raw materials. Sintered in super high temperature rotary kiln, characterized by big hardness , small coefficient of thermal expansion etc, it's ideal raw material of ladle castable and magnesia-spinel bricks.
Specification

Application

It's extensively applied to the lining of converter, glass kiln, open hearth, casting ladle etc.

 In the same condition, using manganese or silicon to deoxidize separately, the burn out rate are 46% and 37%, but it is only 29% if using manganese alloy to deoxidize. So, it is used widely to smelting steel and its output increases faster than ferroalloy's, so has become an indispensable composite deoxidizing and alloy additives in steel industry. The silicon-manganese which contains carbon below 1.9% still is used to produce medium/low-carbon ferromanganese and semi-finished products of electro silicothermic process manganese metal.
