Description
Technical Field
The invention relates to the technical field of pig iron casting recovery, in particular to a surface rust removing device for a recovery type pig iron casting.
Background
In each casting shop, the recovery of pig iron castings accounts for a large proportion of the raw materials of molten iron, but the recovery type pig iron castings need to be subjected to surface treatment before being melted and poured. In particular, the surface of the recycled pig iron casting generally has a large amount of rust, the cost of carbon reduction is too high, and the quality of the formed pig iron raw material is low, so the prior art generally adopts a rust removal gun polishing mode to perform surface treatment on the recycled pig iron casting.
The needle brush of the rust removing gun belongs to a worn article, sometimes, in order to recover a little casting, particularly castings with complex surface structures, the wear rate of the needle brush is high, and therefore the rust removing method is changed.
