Aluminum alloy aging furnace is a special equipment used to eliminate preheating of aluminum alloy materials after initial processing. The main equipment used to reduce the stress concentration and deformation of aluminum alloy materials.
Characteristics of aluminum alloy aging furnace:
1. The hot air circulation system is novel and the temperature uniformity of the furnace is good. 2, temperature PID adjustment control, high temperature control accuracy. 3. Trolley-type furnace bottom, convenient operation, stable operation, labor saving loading and unloading.
Use of aluminum alloy aging furnace:
Aluminum alloy aging furnace is an energy-saving cycle operation furnace, mainly for aluminum alloy castings, aluminum alloy die castings, aluminum alloy wheels, aluminum profile wires, aluminum alloy plates, aluminum alloy grid plates, pistons, etc. Heat treatment.
Brief introduction of aluminum alloy aging furnace structure:
It consists of furnace shell, lining, furnace door, trolley, heating element, ventilator device and temperature control system.
The electric furnace shell is welded with profiled steel as the frame. The inner and outer walls are made of high-quality cold-rolled steel plates, and the coefficient of thermal deformation is small. The inner lining is made of aluminosilicate refractory fiber needle punched blankets as heat insulation and insulation materials to reduce the temperature rise of the furnace wall.
The charging trolley is universal with the quenching furnace.
The furnace door shell is also welded with steel as the frame, the outer wall is also made of cold-rolled steel plate, and the inner lining is also made of aluminosilicate refractory fiber needle blanket for heat insulation and insulation.
The rubber asbestos packing is embedded around the furnace mouth. After the furnace door is closed, it is in close contact with the rubber asbestos packing at the furnace mouth to ensure no heat emission.
Electric furnace heating elements adopt tubular heaters, which are arranged on both sides of the furnace and the surface of the trolley. The resistance wire is made of 0Cr25Al5 high resistance alloy wire, and the outer tube is made of titanium tube, which has a long service life. In order to ensure the uniformity of the furnace temperature, the electric furnace is provided with a ventilator device and a wind guide system. The fan device is installed on the top of the furnace body, and the fan is made of 1Cr18Ni9Ti heat-resistant steel, which is a centrifugal type. The wind deflection system consists of a wind deflector and a wind deflector. The air deflector is installed on the top of the furnace and has an air deflector. When the fan is turned on, the wind is thrown out of the fan, blown evenly to the heaters on both sides of the furnace through the air guide groove, blown into the furnace through the vent at the lower part of the windshield, and then sucked into the fan through the air guide at the lower part of the fan Inside, and then throw it out ..., in this reciprocating cycle, the heat generated by the heater is brought into the furnace, so that the workpiece is evenly heated.
