Zircon Fire Bricks for Glass Firing

Fireproof zircon products – these are acidic materials, which are made from natural zircon sand (ZrSiO4). Zircon fire bricks have good slag resistance, low coefficient of thermal expansion, thermal conductivity, which decreases with increasing temperature, high softening temperature under load, high wear resistance and good resistance to thermal shock and have become important in industry. high temperature material.

What factors are taken into account when choosing materials for glass firing??

Molten glass and flammable materials in the glass furnace will cause certain erosion and damage to the refractory material, What, in turn, will affect the service life of the glass melting furnace. Besides, need to avoid and reduce contamination of molten glass. Thus, The choice of refractory materials is also of great importance for the service life of the glass furnace and the quality of the glass.

How zircon fire bricks are made?

Zircon bricks for glass furnaces are made from zircon as the main raw material with the addition of binders and additives, selected in a certain proportion, and fired at high temperatures after mixing, kneading the dough, molding and drying. Zircon fire bricks are produced according to the production process, and according to physical and chemical indicators they are divided into high-density and dense in density.

Where dense zirconium bricks are mainly used for glass kilns?

Zircon fire bricks are used as the working layer of glass firing pool walls, which have high density and high ability to resist erosion by liquid glass as the working layer of the pool wall.

Properties of zircon refractory bricks for glass firing

1. High fire resistance and high softening point.
2. High resistance to erosion by slag liquid and strong acid resistance.
3. High compressive strength.
4. Good thermal shock resistance.

Method for increasing slag resistance of zircon bricks

1. Products with low porosity and breathability can be obtained, by adjusting the particle composition and changing the molding method, but at the same time this will lead to a decrease in resistance to thermal shock
2. Add additives to improve the viscosity of the brick-slag interaction product
