Refractory Castables
The refractory castables made from diatomite can work as the heat insulation layer of thermal equipment or as the furnace lining that will not be impacted, not be impregnated by molten metals and directly touch flames. They are known for their perfect heat preservation and insulation functions.
At Xinghui, we offer 5 models of diatomite refractory castables which can be used at 900~1200℃. These castable refractories are excellent for use in various thermal industries including metallurgy, power, oil, chemical, machinery, boilers, etc.
Features
1. Popular refractory products with small volume density, high compressive strength, small linear change on reheating and low thermal conductivity;
2. The diatomite products can enhance furnace's integrality and gas tightness, improve thermal efficiency and extend furnace's lifespan.
