Product Description
High strength low cement refractory castable for steel ladlePerformance:Low cement catable is developed on the basis of clay and refractory castables by Kerui Group. It mainly includes low cement, super low cement, no cement or ultra micro powder+sol, etc. Many advantages of refractory castables gather to it, such as high density, low apparent porosity, high strength, low abrasion, thermal shock resistance, corrosion resistance, etc.
Character:The prominent character of low cement castable is high and strong densification which brings benefits of its using:
1. The CaO in it is lower, which reduces the produce of eutectic phase in material and develop its refractoriness, high temperature strength and slag erosion resistance.
2. The water used for the blending of castable during construction is only 1/3~1/2 of water for normal use, which realizes low apparent porosity and high bulk & density.
3. After moulding by casting, the cement compound produced during maintenance is less. There is no damage of large amount of hydrated bond during heating and roasting, which will reduce the medium temperature strength. But for low cement castable, the strength is increasing with the increase of heating temperature.
4. Adjusting the size composition of castable can compound self-flow castable and pump irrigation castable.
Application:Low cement castable is used in the back kilneye, wicket cover and back of cooling machine of cement rotary kiln and other thermal equipment with good performance and long service life.
