Audited Supplier Product introduction
Clay refractory bricks refers to the alumina content of 30% ~ 45%, with good thermal stability, good refractoriness 1580 ~ 1750 ºC, generally for three grades respectively: N-1,N-2.N-3, for the standard.
Product characteristics
1,Bulk density: high density means good densification and high strength.
2, load softening temperature: resistance to high temperature resistance.
3, thermal shock resistance: resistance to rapid changes in temperature without being destroyed.
4, compressive strength: withstand (room temperature) the maximum pressure capacity.
5,Folding strength: the ability to withstand shear pressure.
6, abrasion resistance, impact resistance: good impact resistance, longer use.
7, slag resistance: resistance to slag erosion at high temperatures.
Application areas
Iron and steel, ceramics, cement, chemical industry, glass and other high-temperature kilns, corrosive industrial fields.

Refractory brick is the core material of high temperature industrial kiln lining, in the construction of masonry, pay special attention to the technical requirements of construction, in the masonry of industrial furnace, should be based on the masonry design, through the test to determine the consistency of the slurry and the amount of liquid to add, and at the same time to check the slurry masonry performance (bonding time) to meet the masonry requirements. The bonding time of the mud is the material of the refractory products, the size of the external dimensions of the size of the appropriate 1 ~ 1.5min. different refractory brick masonry, should choose different refractory mud masonry.
Ltd., the company's technical team has been engaged in the refractory industry for more than 23 years, to produce high-grade refractory materials and high-temperature industrial kiln refractory bricks. The company implements a modern enterprise system, its purpose is: high-tech development, high-quality products to win the credibility of excellent service to expand the market. After more than twenty years of hard work, the company has developed into a new type of high and medium-grade refractories manufacturer for petrochemicals, iron and steel plants, thermal power plants, metallurgy, non-ferrous metals, new energy, industrial kilns and other industries.
Our products are sold to Malaysia, Vietnam, Pakistan, Myanmar, Nepal, Russia, Uzbekistan, Kyrgyzstan, Egypt and other parts of the world.
