Unshaped Refractories for EAF

Production Process:

1、Gunning mass of EAF: high-quality magnesia or  forsterite as the main raw material, plus a variety of composite binders, additives are mixed and made

2、Ramming mass of EAF bottom: high-purity synthetic dolomite sand and high-purity magnesia as the main raw material, the appropriate addition of bonding agent is prepared by mixing.

3、Hot repairing mass of EAF slope: synthetic dolomite sand as the main raw material, adding binder and sintering agent by mixing.

The main purpose:

1、Gunning mass of EAF: used for spraying the EAF wall

2、Ramming mass of EAF bottom: used for beating of EAF bottom

3、Hot repairing mass of EAF slope: used for hot repair of EAF slope
