Vacuum Induction Smelting Furnace

Vacuum Induction Smelting Furnace

The vacuum induction smelting furnace is mainly composed of a vertical shell, a smelting furnace, a lid and moving device, vacuum system, hydraulic system, as well as electrical control system. This product is one of these furnaces featuring cycle operations. By far, it is a dedicated furnace for smelting or ingot of cooper or cooper alloys under vacuum or protective atmospheres.
