Abstract: This article discusses a new type of vacuum equiaxed crystal precision casting furnace. The equipment is designed to replace the traditional vertical equiaxed crystal precision casting furnace for the production of thin-walled, large-sized and low-temperature casting parts. The furnace uses a series of innovative concepts and technologies such as horizontal layout, mould heater, coaxial water-cooled cable and coil motion devices. The furnace also has good scalability and can produce fine-grained castings by changing its functional parts.

Key words: equiaxed crystal, precision casting, mould heater, fine grain casting
