Product Description 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.

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.
