According to the working environment of kiln( temperature, atmosphere, raw material component, condition and fuel) and damage reasons of refractory material, the fire brick used in glass kiln should be selected and made corresponding refractory material. Zhengzhou Rongsheng Refractory will introduce the fire bricks used in glass kiln.

Generally, the refractory bricks used in glass kiln include zircon corundum bricks, silica bricks, sintered mullite brick, low porosity clay bricks, light weight insulating bricks, high alumina bricks and direct-bonded magnesia-chrome bricks, etc.

Silica Brick

Silica brick is a kind of acid refractory material mainly made of tridymite, christobalite and a small amount residual quartz and glass phase. Its silica dioxide content is more than 93%, having the characteristics of resistance to acid slag erosion, high temperature, high refractoriness under load, non-deformation under the high temperature for long time, but the heat stability low.

Silica bricks are mainly used in the coke oven, hot blast heater, glass kiln and other thermal equipment. According to the different thermal equipment, silica bricks can be divided into coke oven silica brick, hot blast silica bricks and glass kiln silica bricks.

Low Porosity Clay Bricks

The main material of clay brick is flint clay clinker, clay brick with the apparent porosity below 17% is named as low porosity clay brick. Low porosity clay brick has the characteristics of high strength, high refractoriness, compact structure, low porosity, good thermal shock resistance and anti-stripping. It is widely applied to hot blast heater and glass furnace regeneration chamber. Clay brick plays an incomparable important role of various industrial kiln.

Zirconia Brick

AZS Brick is a kind of fused cast zirconia-corundum refractory brick which is short writing of abbreviation that AZS from “A” of Al2O3, “Z” of ZrO2 and “S” of SiO2. Such as No. 33 fused cast zirconia-corundum refractory brick adopts the “AZS-33#” as its abbreviation, No. 36 fused cast zirconia-corundum refractory brick adopts the “AZS-36#” as its abbreviation and No. 41 fused cast zirconia-corundum refractory brick adopts the “AZS-41#” as its abbreviation.

The structure character of AZS bricks is very important to the ability of resistance to corrosion, low pollution of vitreous humour and the service life, AZS brick is an unique type of refractory. Compared to traditional refractory material, there are great differences between them.

Sintered Mullite Bricks

The main material of sintered mullite bricks is bauxite chamotte, add small amount of clay or bauxite as anchoring agent. And it is made by molding and sintering. The high temperature performance mainly depend on the alumina oxide content and uniformity of mullite phase and glass, it mainly used in the hot blast furnace top, blast furnace shaft and bottom, glass melting furnace regenerator, ceramic high temperature furnace, dead angle furnace lining of petroleum cracking system, etc.
