SK32/SK34/SK36/SK38/SK40 Refractory Brick

2019-12-21
Bricks that can withstand high temperature above I580 ℃ are called refractory bricks. It is a finished product obtained by the following process:
1. B
lend clinker (calcined and crushed clay) with refractory clay
2. Mix thoroughly above blending material
3. Shape mixing material through pressing machine
4. Drying and firing in tunnel kiln.

There are also silica and high alumina bricks. According to the grade, it can be divided into SK32, SK34, SK36, SK38, SK40 refractory bricks. They are mainly used in equipment such as furnace linings, flues, and chimneys. According to their shapes and specifications, they can be divided into two types: standard and irregular. The size of standard refractory bricks are 230mm × 114mm × 65mm, and special-shaped refractory bricks should be processed on-site according to demand or requested by customers. 


Refractory bricks can be divided into two types according to their refractoriness: standard refractory brick (refractoriness is 1580 - 1770 ℃) and high-grade refractory brick (refractoriness is 1770 - 2000 ℃). According to their chemical properties, they can be divided into acid, alkali and neutral 3 types.

Jansincere Refractory, as a professional manufacturer of refractory bricks for more than 30 years since its establishment, mainly includes SK series refractory bricks, super-grade refractory bricks, first-grade refractory bricks, second-grade refractory bricks, and special-shaped refractory bricks. We constantly mention high technology and new technology, so that 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 the advantages of wear resistance, corrosion resistance, anti-stripping, low creep, good thermal shock stability, and 1.5 times the service life of ordinary products. They are mainly used in blast furnaces, hot blast stoves, carbon roasting furnaces, carbon calciner, coke oven, steel drum, casting system, boiler, cement kiln, glass kiln and various kiln linings and thermal equipment, etc., which are suitable for metallurgy, machinery, building materials, casting, ceramics, electricity, petroleum , Chemical and other industries.
