Product Feature
The industrial vacuum cast iron furnace is mainly used for cool work & hot work steel, high speed steel, tool steel material vacuum quenching, tempering and solution-ageing process. And it is divided into horizontal and vertical types. The vertical type vacuum gas quenching furnace is especially suitable for the vacuum gas quenching process of large workpieces with easy deformation such as long rod-shaped parts, shafts and plate parts. The workpieces can keep bright and minimal deformation after heat treatment. Our industrial vacuum cast iron furnace high melting efficiency, good power saving effect,compact structure and strong overload capability. The temperature around the furnace is low,the smoke dust is less. Meanwhile, the operation process is simple and the smelting operation is reliable. It also has other advantages. For example, the metal composition is uniform, high furnace utilization and easy replacement. Our machine is an energy-saving, environmental protection, precise and efficient surface heat treatment process, which can be applied to the surface reinforcement of important parts and tools. Over the years, we have studied theplasma heat treatment technology field extensively and deeply and completed a number of major national research projects and obtained many patents. Our equipment and process technology has been successfully applied in key parts.
