High Temperature Refractory Castable Cement for Steel Mill
Benefits:
1) Good performance to thermal stability, slag and abrasion resistance.
2) Good fluidity and convenient to install and maintain
3) Less installation and drying/sintering time
4) Efficiently reduced the production stoppages & downtimes
5) Labor and cost saving by prolonging campaign length.
