Zibo Tashan Refractory Material Factory is the specialized manufacturer and supplier of refractory in China, Our products mainly include refractory bricks, refractory castable, refractory precast shape, insulating brick etc. For refractory castable and precast shape they are very popular in the Europe, North American area.

Our Refractory Brick: with high refractoriness and mechanical behavior under high temperature.

Refractory brick is the necessary material of high- temperature service, mainly use for industrial furnaces and kilns and thermal equipments.

1. Silica brick is the main refractory bricks used in glass melting furnace;its main crystal phase is Tridymite.
2. Silica brick for glass melting furnace is used in building checker chamber, chute, combustion chamber,coking chamber,and furnace arch etc.
3. Silica brick for glass furnace have following characters:
(1)High refractoriness under load.
(2)High heat conductivity.
(3)Good thermal shock resistance.
(4)Solidity stable of capacity in high temperature.
