Product Description

Pure calcium aluminate cement is using metalurgical grade aluminium oxide and high purtiy calcium oxide as raw mateiral, fired in high temperature furnace then grinding into fine.It is mainly used as binder of high grade unshaped refractory materials which has demand of high load softing temperature, high temperature strenght,good slag resistance and strong reducing gas resistance.Such as for steel plants of ladle cover,oxygen gun and various grade tubes of oil &chemical industries.
