Low Cement Refractory Castable Introduction Low cement refractory castable mainly includes three types: high alumina refractory castable, mulite refractory castable, corundum refractory castable. This series of castable are featured with high strength, anti-scouring, anti-abrasive, and excellent performance.With these characteristics, the low cement refractory castable is widely used as linings in reheating furnace and other industrial furnaces. Application of Low Cement Refractory Castable Rongsheng Refractory has professional sales and after-sale service team who provide customers all-around service about product application, construction installation and operation technology training etc. 

Features

Refractory Castable Features  1.High compressive strength and high stability at high temperature; 2. High compressive strength; 3. Strong resistance to lag erosion and tension; 4. Good resistance to cold and heat or objective environmental changes; 5. Can resist chemical corrosion of acid slug or solution; 6. Compared with the production of refractory bricks, it does not need high temperature sintering and has low energy consumption; 7. The product has diverse performance and can be made into wear-resistant and fire-resistant, lightweight insulation, corrosion and peeling resistant, non stick aluminum, high-strength, acid resistant, alkali resistant, etc. according to usage.
