This design is resistant to mechanical damage and almost completely excludes insulation fibers and shell fragments impurities in the melt. Three months of operation proved that there are no traces of the shell, mesh or internal insulating filler destruction. Mats tightly adhere to upper clamping plates of the metal track. Read...

Practice has shown that preliminary heating ensures faultless start of casting and ceramic foam filter filtration throughout the whole area. Specifically, it is worth noting the simple and efficient heating system that enables to protect heating elements from excessive heat exposure and their further breakdown. The service life of heating elements increases considerably... In the course of operation, the covers' design proved to be convenient, balanced, and good serviceability. The steady-state compressed air cooling system has high reliability to minimize the human factor. Solutions of the kind can be duplicated to heat filters and chutes in other units. Read...
