Gunning mix for hot metal mixer

The usual maintenance of the metal mixer is mainly spray cleaning. The working nature of the mixed iron furnace determines the harshness of spray cleaning environment.

The hot metal mixer is a thermal equipment for storing molten iron in a steel mill to homogenize the temperature and composition of the molten iron. The lining material of hot metal mixer is easy to be damaged due to the action of molten iron scouring, slag erosion, temperature change and large load vibration for a long time. In particular, the slag line, the corner of the front wall and the exit area are weak links, which can easily lead to partial abnormality of hot metal mixer, even forced to stop the overhaul, which seriously affects the normal production of steel making, so the maintenance in peacetime is very important.
