Detailed introduction of quenching furnace

Quenching furnace consists of furnace body, furnace door, heating element, ventilation organization and control system.

The furnace body is welded by section steel and steel plate. The inner wall of the furnace lining is made of stainless steel plate and connected with the furnace shell to form a whole body. The interlayer of the furnace body and furnace liner is filled with aluminum silicate refractory fiber for heat insulation.

The furnace door is planned at the lower part of the furnace body, that is to say, the work pieces enter or exit from the bottom. The lower opening of the furnace body is open, and the opening and closing action of the furnace door adopts the mechanical transmission method, which is completed through the motor, reducer, sprocket, chain, track, etc.

The heating element is made of high resistance alloy resistance tape, which is placed on both sides of the inner tank through a special hook and insulated from the inner tank.

The fan is composed of blower and air guide plate. The blower motor is electrically interlocked with the heating element. The heating element can only be powered on when the blower is connected, so as to ensure that the heating element can work under the condition of ventilation cycle. The charging basket and charging and discharging car are welded by section steel, and the horizontal center of gravity is adjusted and hoisted up and down. The electric furnace is equipped with a charging basket and a charging car to ensure that users can work in time. When feeding, the charging basket is installed on the trolley, pulled out and pushed. When entering the lower part of the furnace, the furnace door is open and the hoist works. Hook the chain, lift the charging basket into the furnace, and close the furnace door for heating. When discharging, open the furnace door, hoist action, put the charging basket into the pool for quenching treatment, then lift the basket out of the water and put it on the plane of the trolley, the chain is decoupled, the hoist is raised, and the trolley is pulled out for aging treatment.

A pool is arranged at the lower part of the furnace body so that the workpiece can enter the pool for quenching in a short time.

Some controls use silicon controlled rectifier and digital display meter to control and alarm the temperature.

The electric furnace is equipped with a limit switch on the door opening and closing organization and the loading lifting organization. This switch is connected with the power supply of the control cabinet. When the workpiece rises to the highest point, turn on the door opening and closing power supply and touch the power supply of the heating element. When the furnace door is opened, cut off the power supply of heating element and connect the power supply of lifting organization to lower the workpiece for water quenching.
