Bath Type Low Pressure Casting Holding Furnace
Bath Type Low Pressure Casting Holding Furnace Equipment Characteristics ◆ The furnace body bears high pressure and high strength. The furnace shell is welded by high strength steel plate. When the test pressure is 0.25 MPa, there is no deformation on the shell. ◆The sealing performance of the furnace body is great. The furnace cover, door and rod connection are reliably sealed with the furnace body, and there is not gas leaks. ◆ No crucible loss. Non-metallic aluminium melt pool, no crucible loss, low use and maintenance costs. ◆ Liquid aluminum does not increase iron. Non-metallic molten pool, aluminum liquid without iron hyperplasia and other pollution. ◆ The melt pool has a long service life. The molten pool is casted with low cement castable for aluminum alloy, which is resistant to aluminum liquid erosion and has a service life of more than 3 years. ◆ Good insulation performance. The lining insulation adopts high-quality insulation materials such as silicon-calcium plate and nano-plate, and the temperature rise of the furnace shell surface is less than 60 °C. ◆ High temperature control precision. With the intelligent temperature control instrument and aluminum temperature thermocouple, the double loop control of aluminum liquid and furnace temperature is realized, and the temperature control accuracy reaches ± 2℃.
Bath Type Melting Furnace Equipment Features ◆ The molten pool is formed by integral injection molding with non-infiltrative and high-strength injection-resistant material (Allied Mineral), and the molten pool does not adhere to aluminum, which slows down the formation of corundum tumor. ◆ Non-metallic molten pool, liquid aluminum without iron hyperplasia and other pollution. ◆ The melt hearth service live is more than 3 years. ◆ The furnace village adopts multi-layer anti-leakage technology, without the consideration of aluminum liquid ' string leakage ' lining. ◆ The furnace cover has a cylinder rotating lift, which is convenient for molten pool cleaning, slag removal operation, furnace cover and electric heating element maintenance. ◆ It has a variety of safety protection such as aluminum liquid over-temperature alarm and furnace over-temperature alarm.
Count Pressure Casting Holding Furnace
Count Pressure Casting Holding Furnace The electrical type counter pressure furnace is made of high-quality electrical resistance wire as heating element. The furnace lining is composed of fiber module and fiber blanket, which has less heat storage and good heat preservation performance. The crucible furnace is suitable for graphite crucible. The crucible has good high temperature oxidation resistance and can be used for melt insulation before differential pressure casting. The crucible furnace is equipped with a power plug, which can be conveniently, safely and reliably connected with the power socket on the counter pressure casting machine.
