Glass production process

Glass: an amorphous solid substance obtained by cooling and hardening of a molten substance. The production process includes the preparation of raw materials – the melting of molten glass – the shaping of glass products – the annealing of glass products. The process in the glass kiln includes the mixing of glass batch materials in a reasonable It melts into a liquid phase under the temperature regime, homogenizes and clarifies it, and becomes a transparent liquid.

Silica brick

Silica bricks are refractory products with a SiO2 content of more than 93%. They are made from silica with a silicon content of >96%, adding mineralizers and binders, and then mixing, shaping, сушка, and firing. They are mainly used for coke oven carbonization. Chambers, combustion chambers and partition walls, glass kiln roofs, kiln walls, high-temperature load-bearing parts of hot blast furnaces carbon roasting furnaces, and other kilns. True density <2.35. It is an acidic refractory material, which is highly resistant to acidic slag or acidic solution corrosion, but has poor resistance to alkaline corrosion; the load softening temperature is high at 1640~1680℃; It has poor thermal shock resistance and fire resistance of 1690~1730℃.

Fused zirconia corundum brick

Fused zirconia corundum bricks are used to build kiln pool walls, flame space parapets, small furnace spouts, small furnace level gates, small furnace stacks, tongue gates, г.д. Fused zirconia corundum bricks with 41% zirconium content are used for The corners of the masonry pool wall, the liquid flow hole, and other parts where the glass liquid has the most severe erosion on the refractory material. This material is the glass industry’s most widely used fused cast refractory.
