Product introduction of aluminum alloy quenching furnace
The aluminum alloy quenching furnace is composed of a heating furnace cover and a mobile chassis. A crane is mounted on the top of the square (or round) furnace hood, and the basket can be hoisted to the furnace through a chain and a hook. The furnace cover is supported by section steel, and the bottom has a pneumatic (or electric) operated furnace door. The bottom frame located under the furnace hood can be moved and positioned along the track, and the bottom frame carries a quenching water tank and a basket. During production, move the basket on the bottom frame directly under the furnace cover, open the furnace door, lower the chain and hook to hang the basket into the furnace, close the furnace door and heat. Quenching is ground. First, move the water tank on the bottom frame directly under the furnace cover, then open the furnace door, lower the chain, and quench the material basket (workpiece) into the water.
Features of the equipment (1) Temperature uniformity To achieve the temperature uniformity required by the user, it is related to the design of the circulating fan, air hood, furnace structure, electric heating power distribution, electric heating element layout, control method and process, and furnace door structure. To guarantee.
(2) The advanced nature of advanced mechanical systems is guaranteed by design, component selection and quality, and manufacturing quality. The mechanical system runs smoothly and reliably, and the equipment is in a low noise and low vibration working state.
(3) The perfect control system is reflected in that 100 ~ 650 ℃ can achieve precise temperature control, the system is stable and reliable, easy to operate, avoiding human error operation, and complete functions.
(4) The quenching transfer time is fast, the adjustable furnace bottom facing door, double-speed lifting mechanism, and advanced hydraulic mechanical system make the quenching transfer fast and reliable, and the time can be adjusted according to the user's process requirements.
Aluminum alloy quenching furnace is suitable for solution treatment and aging treatment of large and medium-sized aluminum alloy product parts.

Equipment structureAluminum alloy quenching furnace consists of furnace body, furnace body steel bracket, detachable furnace roof, furnace lining, electric heating elements, circulating fan, air deflector, furnace bottom open-type furnace door, double-speed lifting mechanism, material rack, quenching It is composed of tank, material truck, control system, power distribution cabinet / control cabinet, hydraulic system, etc.
The furnace shell frame is welded with profiled steel, the inner wall is made of 1Cr18Ni9Ti heat-resistant steel plate, the inner lining is made of high-quality all-fiber structure, and the inner surface of the furnace shell is attached with a layer of rubber asbestos board, which acts as heat insulation and protects the surface of the furnace shell from corrosion.
The heating element is made of 0Cr25AL5 alloy wire wound into a strip shape. It is sheathed on an insulating porcelain tube and fixed to the furnace shell by stainless round steel. This structure resistance band is suspended around the furnace chamber, which is conducive to heat dissipation and circulation.
The hot air circulation device consists of a fan device and a wind deflector. The fan device is placed on the top of the furnace body. The fan is made of 1Cr18Ni9Ti heat-resistant steel into a centrifugal air blade. The air deflector is made of 1Cr18Ni9Ti heat-resistant steel. It is fixed on the inner wall of the furnace through several shelves. The resistance band is wrapped inside. The heat emitted by the resistance band is thermally circulated through the hot air circulation system to make the temperature in the furnace uniform. The ventilation device is made according to the volume of the furnace to ensure that the number of hot air cycles is more than 40 times / minute.
The base frame is used to place the furnace parts, and is welded by profile steel.
Furnace door shells are welded with steel and the inner lining is made of high-quality all-fiber structure.
The furnace door and furnace body are sealed with aluminum silicate refractory fiber material.
The electric furnace is equipped with two trolleys.
The lifting mechanism is composed of a hoist, a loading frame, a lifting hinge, and a rolling wheel.
The hoist is installed on the side of the base frame, adopts a low speed ratio reducer, and has a self-locking device, which can ensure that the loading frame stays at any position and runs at a reduced speed, and prevents the loading frame from hitting the quenching tank quickly when it is lowered.
The loading frame is made of profiled steel according to user requirements.
The hoisting device frame is drawn by steel cables.
The heating element adopts strip-shaped electric heating elements, which are respectively arranged on both sides of the furnace. The material is 0Cr25AL5 alloy wire, which has a long service life. Each mechanical transmission part of the electric furnace adopts chain control, that is, the fan device and the power supply of the heating element are automatically cut off after the furnace door is opened. After the furnace door is closed in place, the power of the fan device and heating element can be switched on to prevent malfunction and accidents due to misoperation. The system has sound and light alarm function.
Temperature control system adopts PID zero-crossing triggering thyristor and intelligent meter to control temperature. In addition, the multi-point automatic recorder of Shanghai Dahua Instrument Factory is used to record the temperature and the over-temperature alarm to ensure that the workpiece is not over-temperature. The temperature controller is also equipped with a communication port to communicate with the central control computer. The temperature control value of the process The parameters such as heat preservation time are uniformly programmed and managed by the central control computer. The depth of the quenching pool is 1.5 times higher than the loading frame, which can ensure that the workpiece is quenched and cooled in the quenching pool. The electric heating pipe is used for heating in the quenching pool. And automatically controlled by temperature measuring instrument. The pool has a water inlet to cool the water temperature, and a circulating water pump is set in the pool for hot water spray circulation to make the temperature uniform.

Refractory fiber cotton sand sealing knives are embedded around the furnace mouth. After the furnace door is closed, it will be in close contact with the knife at the furnace mouth to ensure no heat emission.
