According to the different requirements of each part of the cement kiln, our company has designed and developed lightweight alkali resistant castables, alkali resistant castables, high strength refractory castables, steel fiber reinforced castables, and high alumina low cement refractory castables, etc. Especially, the low cement castables have high density, low porosity, and good hot strength and thermal shock stability; remarkable refractoriness and loading softening temperature, excellent impact and abrasion resistance. Excellent impact resistance and abrasion resistance. It is very suitable for kiln head and kiln tail.
