Pit aluminum aging furnace
Pit aluminum aging furnace is energy-efficient furnace operation cycle, one belonging to Pit resistance furnace. Pit aluminum aging furnace built stainless steel draft tube. By improving air circulation, improve temperature uniformity and temperature control accuracy. Mainly for aluminum castings, aluminum die casting, alloy wheels, aluminum plates, aluminum grid plate, pistons, etc. at a high state average temperature aging heat treatment, heating, melting, solution, insulation, etc. purposes, but also for tempering process other metal parts.
Pit aluminum aging furnace is used to eliminate the post-processing of aluminum material preheated by the beginning of the special equipment. For the purpose of reducing the stress concentration in the aluminum alloy, to reduce the deformation of the aluminum alloy material of the main equipment.
The aging furnace with hot air circulation system is novel, good temperature uniformity degrees. PID temperature regulation and control instrument (see below), high precision temperature control. Easy operation, smooth running, loading and unloading of the workpiece and effort, mature technology advantages.
The aluminum structure and general aging furnace oven similar to the furnace shell, lining, door, car, heating t and temperature control system and other components.
Aging furnace shell with welded steel for frames. Inner and outer walls are made of high-quality cold-rolled steel production, thermal deformation coefficient is small, h aluminosilicate refractory fiber blanket acupuncture for insulation and insulation materials, reduce the temperature rise of the furnace wall.
Tubular heaters electric heating around the furnace, resistance Cr25Al5 high resistance alloy vice life. In order to ensure uniformity of furnace temperature, electric fan means and provided ventilation system. Ventilator device is mounted to the top of the furnace, the fan used 1Cr18Ni9Ti heat-resistant steel production, centrifugal. Ventilation system by a wind deflector and plates. Deflector mounted on top of the furnace, there are guide duct. After turning on the fan, the wind from the fan thrown by the wind blowing on the furnace tank evenly around the heater vent through the lower part of the windshield blown furnace, and then suction fan within the lower portion of the guide from the fan outlet then thrown ......, and so forth cycle, the heat generated by the heater into the furnace, the workpiece is heated evenly.
