The aluminum alloy quenching furnace consists of a heating furnace hood and a mobile chassis. The square (or round) furnace hood is equipped with a crane, and the basket can be hoisted to the furnace through chains and hooks. The furnace hood is supported by a profiled steel and the bottom of the oven door is operated pneumatically (or electrically). The base frame below the furnace hood can be moved along the track and positioned. The chassis carries the quenched water tank and basket. During production, the basket on the base frame is moved to the bottom of the furnace cover, the furnace door is opened, the chain and the hook are lowered, the material basket is lifted into the furnace, and the furnace door is closed and heated. The quenching is the ground. First move the sink on the bottom frame directly under the hood, then open the door and put down the chain to quench the basket (workpiece) into the water.

Equipment structure
Aluminum alloy quenching furnace consists of furnace body, furnace body steel frame, removable furnace top, furnace lining, electric heating element, circulating fan, air guide plate, furnace bottom split oven door, double speed lifting mechanism, material rack, quenching tank, Transportation vehicle, control system, distribution cabinet/control cabinet, hydraulic system, etc. The shell frame of the furnace body is welded with steel. The inner wall is made of 1Cr18Ni9Ti heat-resistant steel plate. The inner lining is made of high-quality fiber structure. A layer of rubber asbestos is attached to the inner surface of the furnace shell to provide heat insulation and protect the surface of the furnace shell from corrosion. The heating element uses a heating element made of 0Cr25AL5 alloy wire wound into a strip shape, set on the insulating porcelain tube, and is fixed on the furnace shell by a stainless steel round bar. The structure resistance band is suspended around the furnace cavity, which is favorable for heat dissipation and circulation. The hot air circulating device consists of a fan device and a wind deflector. The fan device is placed on the top of the furnace body, and the fan is made of 1Cr18Ni9Ti heat-resistant steel into a centrifugal fan blade. The air guide plate is made of 1Cr18Ni9Ti heat-resistant steel, and is fixed on the inner wall of the furnace through several bars, and the resistance band is wrapped inside. The heat generated by the resistance band is circulated through the hot air circulation system to make the temperature inside the furnace uniform. The ventilation device is made according to the volume of the furnace, ensuring that the number of hot air cycles is more than 40 times/minute.
The base frame is used for shelving furnace parts and is made of welded steel.
The door shell parts are welded by steel and the inner lining is made of high-quality, all-fiber structure.
The seal of the furnace door and furnace body is made of aluminosilicate refractory fiber material.
The electric furnace is equipped with two trolleys. The lifting mechanism is composed of a hoisting machine, a charging frame, a lifting hinge, a scroll wheel, and the like. The winch is installed on the side of the base frame, uses a low speed ratio reducer, and has a self-locking device to ensure that the loading frame stays at any position and decelerates to prevent the charging frame from rapidly hitting the quenching tank when it falls. The loading frame is made of profiled steel according to the user's requirements. The lifting device frame uses wire rope traction.
Quench the depth of the pool more than 1.5 times the charging frame, to ensure that the workpiece quenched in the quenching pool cooling, quenching the pool with another electric heating tube for heating. And through the temperature meter automatic control. The water inlet of the pool can be used to cool the water. A circulating water pump is provided inside the pool for hot water injection to make the temperature even. There is a fire-resistant fiber-cotton sand-sealing knife embedded around the furnace mouth. After the furnace door is closed, it is closely attached to the insert of the furnace mouth to ensure that there is no heat dissipation. The heating elements are strip-shaped heating elements, which are arranged on both sides of the furnace and are made of 0Cr25AL5 alloy wire, which has a long service life.
Each mechanical transmission part of the electric furnace adopts chain control, that is, it automatically cuts off the fan device and the power supply of heating elements after the furnace door is opened. After the furnace door is closed, the fan unit and the heating element can be turned on to prevent malfunctions and accidents. The system has a sound and light alarm function. Temperature control system uses PID zero trigger thyristor, smart watch temperature control. Another use of Shanghai Dahua Instrument Factory multi-point automatic recording temperature and over-temperature alarm recording dual control, to ensure that the workpiece does not exceed the temperature, the temperature controller also set up a communication port, can communicate with the central control computer, temperature control process of numerical Parameters, such as holding time, are centrally controlled and programmed by the central control computer.
