Detailed Product Description:
- Hardening patch fast: Long service life
- Place of Origin: China (Mainland)
- Material: MgO-Carbon Brick
The product has the advantages of hardening patch fast, good liquidity pour into the furnace, 30 ~ 35 minutes be hardened.
The product combined with the actual situation of converter, and the successful development with scientific research units of large converter rapid hardening repair materials with hardening patch fast, good fluidity poured into the furnace, 30 ~ 35 minutes be hardened, compared to the traditional tar dolomite each fettling may be shortened by up to 30 ~ 40 minutes, furnace service life can reach 5 to 7 heats.
The performance as below:
