Product Descripton of Rongsheng High Temperature High Quality Low Cement Castable For Kiln
The refractory product range includes low cement castable of different Alumina content (Al2O3 varying from 45% to 90%) with service range between 1450 °C to 1800 °C. These are characterized by Al2O3 content and specific low Fe2O3 and low CaO content. Also water requirement for casting is less than 5%. These castables have very short curing time requirement. These are suitable for use in places where very quick setting is required thus reducing the downtime of Furnaces.
Rongsheng Refractory have been the Leading manufacturer, Supplier & Exporter of top-quality shaped and unshaped refractory materials for more than 20 years. Our Low and ultra-low Cement Castables mainly includes three types: high alumina refractory castable, clay refractory castable, corundum refractory castable. They have the characteristics of small pore size, large density, good volume stability, high strength and small amount of water. They overcome the characteristics that the strength of ordinary castables decreases significantly at 800~1200 ℃, increase with the increase of temperature, and have excellent thermal shock resistance, slag resistance and corrosion resistance. The Low and ultra-low Cement Castables are high quality, competitive price, fast delivery and direct supply by manufacturer.
1.High refractoriness, high temperature strength and slag resistance.
2.Low porosity & High bulk density.
3.Low water content.
4.High strength.
5.High thermostability.
High Alumina Low Cement Castable is developed based on refractory castable bonding clay, which has the varieties of low cement castable, ultra low cement castableb, non-cement or submicron powder and soild binder.
1.High density.
2.Low porosity.
3.High strength.
4.Low abrasion.
5.Thermal shock resistance.
6.Resistance to erosion.
7.Good using effect.
Low cement and ultra low cement castable’s service temperature is higher than the same materials common refractory castable.
1.Low cement castables are used for linings of iron runner for blast furnace, iron notch for iron-melting furnace, pretreatment of hot metal monolithic powder gun.
2.Clay and high alumina low cement castable can be used for all kinds of thermal treatment furnace of heating furnace and soaking pit and rotary kiln linings.
3.Corundum and Zirconia-corundum low cement castable refractory material can be used for pats’ linings of molten steel furnace refining device.
4.Mullite low cement catable can be used for linings of high temperature nozzle and water-cooled tube binding lings of heating furnace.
