Filtration of melt
Our company designs, manufactures and supplies filtration units with different types of heating system.
Benefits of filtration units:
- Quick start of casting and maximum use of effective surface of the ceramic foam filter due to its convection preheating with hot air
- High speed of cartridge and ceramic foam filter warming-up
- Maximum use of the effective surface of the ceramic foam filter due to convective preheating with hot air or combustion products
- Possible application of phosphate-free ceramic foam filters
- Preheating of melt during casting in filtering boxes with electrical heating system
Advantages of our products:
Possible uniform heating of two-stage filters to a temperature of 650-700⁰C
Quick warming-up. gas filters: single-stage 20 min., two-stage 30 min. single-stage electric filters 60 min.
The flexibility of technological modes settings for solving specialized customer’s tasks using several methods of heat transfer in combined heating systems
Convenience and safety of the operating personnel during the use of filter covers
Special design for operation in rough conditions: at high dust conditions, polluted air and low quality of electrical power
Unification of the automated control system: PLC and HIM based
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...
Possible design of filter box chambers for 10-23″ filters:
- Double filtration
Heating system options:
- Without a heating system
- With radiation heating system (filter box cover radiating surface always faces down)
- With convection heating system (air blowing/vacuuming tool and hot air gun are used for blowing)
- With combined heating system (radiation and convection heating)
