furnace lining material/srapid hardening repair material for all kinds of furnaces
1) High purity and high active magnesium oxide
2) Good liquidity and rapid hardening ability
3) High adhesive property
The most easily eroded part is the steel tapping hole of the electric furnace and converter, because of its special place, it is hard to repair, need more time and labor. Even may not get the most effectiveness. Our rapid hardening repair material just can make up for the disadvantages. It is made of high purity magnesium raw material together with vitrified bonded, become the new type of alkaline amorphous refractory. It is of many advantages:
1) High purity and high active magnesium oxide
2) Good liquidity and rapid hardening ability
3) High adhesive property and durability
4) Slag corrosion resistance
5) Operate easily
It can apply to the cold condition, to reach its efficiency, customers can adjust the water addition themselves according to the furnace temperature and actual repairing condition.
