A few days ago, the three new heat treatment production lines of ZWZ Group Bearing Parts Branch were put into operation on schedule, realizing the automation, standardization and traceability of the whole process of bearing heat treatment processing with first-class international industry standards. The largest bearing steel heat treatment production base in Northeast China of ZWZ Group Bearing Parts Branch was put into operation.
The renovation project started in October 2021, adding a heat treatment production line consisting of 6 sets of multi-purpose furnaces, a 1250 salt bath martensitic heat treatment production line and a 1250 salt bath bainite heat treatment production line.
