China Factory Direct High Strength Wear Resistant Refractory Castable for Boiler
China Factory Direct High Strength Wear Resistant Refractory Castable for Boiler
Corundum wear-resistance castable is made from special grade corundum, alumina, etc. as the aggregate and segregation, added with bond, moderate heat resistance stainless steel fibre and some additive. It is of good anti-stripping and shock resistance, is the ideal wear-resistance material for circulating fluidized bedboiler.
Characters:
high cold-hot strength, good wearing resistance, thermal vibration resistance, anti-stripping and good stability under high temperature.
Corundum castable is our high quality superior product, mainly including corundum castable, corundum plastic refractory, corundum ramming mix and corundum wear-resistance material. Corundum products are of good high temperature strength, wear-resistance, anti-scouring, high thermal conductivity, thermal vibration resistance, corrosion resistance, good leakproofness, rapid hardening and reaching to using strength standard etc. They are widely used in circulating fluidized bedboiler, metallurgy, petrochemical industry and thermal power industry, etc.
Application:
Put proportional steel fibre and additive into corundum castable to produce steel fibre wear-resistance castable which is of good thermal stability and strong wear-resistance, used in heating furnace bed, steel spout, mouth of cement rotary kiln and other parts.
Customized castables and prefabs of this series castables can be processed according to customer’s drawings and requests.
Welcome to contact us if you have any request for corundum wear-resistance castable or you have any question about it. We support large number of custom-made products for all types of refractory material and customized special refractory material.
Looking forward to every cooperation with you!
