Product Desciption
Fused cast mullite series is made of high grade mullite grog. It is cast and moulded by electrode arc furnace with high temperature.
Application
Fused cast mullite series is supposed to be mainly used in positions required good wear-resistance and high temperature resistance, such as sliding rail blocks of pusher-type reheating furnace and steel tapping spout of step-type heating furnace and garbage incinerator lining.
Characteristics
Fused cast mullite series has high refractoriness to more than 1790ºC and good abilities of Refractoriness under load, cold crushing strength and thermal shock resistance.
