Analysis of the Quality Control System for High-Manganese Steel Castings in Crusher Components
With the upgrading of domestic crushing equipment manufacturing technology, high-manganese steel castings have been widely used as core components in wear-resistant parts such as jaw plates and hammer heads—key accessories for crushers. The production of these specialized steel castings features distinct process characteristics: they are typically manufactured using a single-piece, small-batch production model, relying primarily on manual sand-mold casting techniques. Moreover, their quality-control system encompasses multi-dimensional critical factors.
