Cross wedge rolling molds are very complicated and bulky. It takes a lot of time and energy to process. And the cost of the materials and the processing of the molds is expensive. If the mold is discarded, large waste will be generated. Since the center distance of the rolling mill is adjustable, the old mold can be repaired and renovated to reach a reusable state. This kind of renovation plays a pivotal and practical role in saving the cost of the mold, and it also meets the requirements of energy saving, low carbon, and environmental protection in advanced manufacturing in China.
