China 2021 China New Design Acid Refractory Bricks - China Glass Furnace Silica Brick from Real Factory – Rongsheng factory and manufacturers | Rongsheng

Silicate carbon brick belongs to neutral refractory, which withstands erosion of acid and alkali slags, solvents, and other chemical corrosion. Silicon carbide has characters of high strength, good anti-oxidation resistance, and no transformation at high temperature. In all raw materials of the non-oxide refractory bricks, slilica carbon brick is the most economical and most widely used in some place. which can be used in different industries, such as the stone industry, glass industry, metal industry, printing industry, and light industry. Besides, Silica carbon brick for sale has much excellent performance on resisting very bad environment erosion, such as high heat conductivity, good abrasive resistance, great thermal shock resistance, strong resistant to acid and alkali slag erosion and low heat expansion coefficient and etc.

Properties of Silica Carbide Brick

• High strength,
• High heat conductivity,
• Good abrasive resistance,
• Great thermal shock resistance,
• Excellent erosion resisting,
• Strong resistant to acid and alkali slag erosion,
• .Low heat expansion coefficient.

Composition of Silica Carbide Brick

Silicate carbide block raw materials are silicon carbide, about 72%-99%. Silicon carbide is also called the moissanite, corundum sand or refractory sand. which is made by quartz sand, petroleum coke or coal tar, and wood bits, being produced by high temperature smelting in the electric resistance furnace.

Silica Carbide Brick Manufacturing Process

Silicon carbide brick are produced from silicon carbide, a raw material synthesized in a resistance-type electric furnace at temperature exceeding 2500°C, through the reaction of silica with carbon. Silcate carbon bricks have a thermal conductivity ten times that of fireclay refractories, good corrosion and thermal shock resistance, and can be formed into complex shapes. Silica cabon brick can withstand slag attack and flame erosion.

Silica Carbide Brick Classification

Silicon carbide refractory brick can be classified into clay bonded silicon carbide bricks, Si3N4 bonded silicon carbide bricks, Sialon bonded silicon carbide bricks, β-SiC bonded silicon carbide bricks, Si2ON2 bonded silicon carbide bricks and recrystal silicon carbide bricks.
