High Quality Alumina Cement Refractory Cement For Boiler
Product Description
Refractory Alumina Cement
Description of alumina cement
Refractory cement is a kind of the refractory material use high quality corundum, alumina magnesia spinel and fused magnetite as raw materials, this refractory mate-
rial is characterized of resistance of high temperature, resistance of erode and
emersion, long life used. What's more, it can be made difference kinds of ladle as your request
