Cooling systems are mostly integral spray systems, which cannot adjust the cooling rate in different areas, resulting in overcooling of small workpieces and insufficient cooling of large workpieces. Therefore, an auxiliary device for heat treatment of non-ferrous metals is needed to solve this problem. Utility Model Content
