Bricks that can withstand high temperatures above I580 °C are called refractory bricks. It is a finished product obtained by mixing refractory clay with clinker (calcined and pulverized clay), stirring, pressing and molding, drying and calcining.
There are also silica and high alumina bricks. According to the grades, it can be divided into SK32, SK34, SK36, SK38, SK40 refractory bricks. Refractory bricks are mainly used in furnace linings, flues, chimneys, etc. According to their shapes and specifications, they can be divided into two categories: standard and special-shaped. The specifications of standard refractory bricks are 230 mm x 114 mm x 65 mm, and special-shaped refractory bricks can be processed on-site or supplied by the manufacturer as required.
Refractory bricks can be divided into two types according to their refractory degree: ordinary type (refractory degree of 1580-1770℃) and advanced refractory brick (refractory degree of 1770-2000℃). According to their chemical properties, they can be divided into acid, alkaline and neutral. 3 types.
Our company is a professional manufacturer of refractory bricks that has been established for nearly 30 years, mainly including SK series refractory bricks, super-grade refractory bricks, first-class refractory bricks, second-class refractory bricks, and special-shaped refractory bricks; we continue to improve new technologies and new processes; The product quality meets the needs of different customers; the National Ceramics and Refractory Product Quality Supervision and Inspection Center regularly supervises and inspects to ensure the stability of product quality.
The refractory bricks produced by our factory have wear resistance, corrosion resistance, peeling resistance, low creep, good thermal shock stability, and the service life is 1.5 times that of ordinary products; mainly used in blast furnaces, hot blast stoves, carbon roasting furnaces, and carbon calcining. Furnaces, coke ovens, ladles, casting systems, boilers, cement kilns, glass kilns and various kiln linings and thermal equipment, etc., suitable for metallurgy, machinery, building materials, casting, ceramics, electric power, petroleum, chemical industry, etc. industry.
