1.7 × 1.7m aluminum alloy quenching furnace
Aluminum alloy quenching furnace is a periodic operation type resistance furnace, which is mainly used for solid solution treatment such as rapid quenching and tempering of aluminum alloy. The quenching furnace for aluminum alloy castings is standardized after quenching and solid solution through this equipment. The heating rate is controlled to rise to a certain temperature for a certain period of time and cooled at a certain speed to change the structure of its alloy. Its main purpose is to improve the alloy. Mechanical properties, enhanced corrosion resistance, improved processing, and dimensional stability. Rapid solution treatment. After the constant temperature time is over, the transfer speed of the workpiece is within 10 seconds.
The quenching furnace for aluminum alloy castings is mainly composed of a heating furnace body, a lifting mechanism, a charging trolley, a mobile quenching water tank, a quenching material rack, and a temperature action control. The furnace body is mainly composed of a shell, a furnace lining, a heating element, a hot air circulation and diversion device, a material rack and a material rack lifting mechanism, a furnace bottom door and a pneumatic opening device. The furnace lining consists of two parts, and the furnace body part adopts a composite structure composed of ultra-lightweight energy-saving bricks and aluminum silicate fiber boards. The top part of the furnace is movable, and high-quality aluminum silicate needle felt is used as the thermal insulation material. The structure is reasonable in design, has good thermal insulation performance, low temperature rise of the furnace wall, energy saving and consumption reduction. The heating element is made of 0cr25al5 iron-chromium alloy in a spiral shape and evenly distributed on the wire bricks around the west of the furnace wall to make the temperature in the furnace uniform.
In order to make the temperature uniformity in the furnace meet the requirements of the quenching process of aluminum alloy workpieces, a powerful centrifugal fan is also set on the top of the furnace body. The centrifugal fan can effectively circulate the hot air flow under the action of the furnace's diversion system. The flow system is made of high-quality heat-resistant stainless steel plate. In order to prevent deformation in the furnace, the deflectors are installed in a suspended manner. Its structural performance is stable and reliable, and the equipment requires no maintenance for long-term work.
The lifting of the material rack is completed by a hoisting hoist provided outside the furnace, and the hoisting system is provided with a two-speed driving loading. After the furnace door is opened, the hoist automatically lowers quickly, and the material rack full of workpieces is quickly quenched into the water. When the material rack is ready to enter the furnace again, the hoist lifts the material rack at a slow speed to effectively prevent the workpiece from inertia. Ensure smooth operation without damaging the seals and insulation of the furnace mouth.
Furnace door When it is necessary to open and close the furnace door, the manual point machine opening and closing switch is completed by the worm chain speed governor and the motor. The furnace door is dropped from the furnace mouth, onto the slide rail and returned to the outside of the furnace mouth, so that the workpiece can be quickly quenched into the groove from the furnace. The mobile quenching tank is mainly composed of a feeding station and a water tank. The quenching tank is provided with a driving mechanism, and the tank is provided with a heating system and a quenching medium circulating cooling device.
