Coke

[Product Specifications]: Various specifications of sand, powder

[Production capacity]: 50,000 tons / year

[Scope of application]: 1. The production series of refractory materials are ideal materials for manufacturing high-quality refractory bricks, kiln castables, daily ceramics, clay crucibles, push plates, box bowls, and precision casting sands 2. New materials for aluminum electrolytic cells In the production of advanced refractory materials, manufacturing ceramics, aluminum silicate refractory fiber production and military industries.

【product description】:

The cokestones (hard clay clinker) produced by our company have the characteristics of white appearance, high bulk density, stable physical and chemical indicators, good fire resistance, and standard processing particle size. Coke gems have the characteristics of stable volume, high strength and low water absorption after calcination at high temperature. The indicators for measuring the sintering degree of coke gemstones are generally true specific gravity, bulk density, porosity, water absorption, and shrinkage. Good sintered cokestone has a water absorption of less than 5% and a bulk density of more than 2.55g / cm3.

Cokestone is a mixture of aluminosilicates. The main chemical components are two oxides of Al2O3 and SiO2. The impurities are mainly oxides of alkali, alkaline earth, iron, titanium, and some organic substances. Various oxides play a role of fluxing, which will reduce the fire resistance of the raw materials. Therefore, the lower the content of impurities in cokestone, especially the Na2O + K2O content, the higher the fire resistance. The closer the Al2O3 / 3SiO2 ratio is to the theoretical value (A / S = 0.85), the higher the purity of coke gemstone. The larger the A / S, the higher the fire resistance of the cokestone, and the wider the sintering and melting range. The refractory of high-quality cokestone can reach above 1750 ℃. ...
