Unit on the basis of two covers with convection heat guns for warming-up of refractories prior to casting

The unit was developed with consideration of peculiarities of the Wagstaff casting machine. It is based on 2 power-driven covers with convection heaters blowing of which is performed with the designated system developed by our company and based on the operation of the air blowing/vacuuming tool with cyclone dust cleaning. Application of the unit, along with convenient operation and even heating, allowed to avoid entering of floating crystals into products.
