High Performance Ramming Mix Refractory Iron Ditch Castables 20 Mpa Compressive Strength
Introduction
Iron ditch castable is the blast furnace cast iron ditch lining used in the refractory castable, in iron ditch lining choice of castable overall casting, iron ditch castable main components are fused corundum, silicon carbide and fixed carbon, add binder and additives, through mixing and forming of unshaped refractory.
1. Strong enough to resist the scouring of molten iron and slag;
2. Short operation period before furnace, and minimize the time for furrow or repair.
3. Less amount of water, good fluidity and fast baking of castable
4. Good thermal shock resistance and oxidation resistance;
5. High filling density and volume stability;High performance ramming mix refractory iron ditch castables
6. Castable has low adhesion rate to molten iron and slag, and strong erosion resistance.
7. Effectively extend the service life of ditch lining, reduce the consumption of refractory materials.
