Six structures of heat treatment furnace

1. The shell of the heat treatment electric furnace is made of cold-rolled steel plate, the surface is treated with plastic spraying technology, the furnace door is arranged with side open type, sensitive opening and closing.

2. Medium temperature box furnace selects closed furnace, which is made of spiral shape with electric thermal alloy wire as the heating element and encircles the four walls of the furnace, so as to extend the service life uniformly during heat dissipation.

3, high temperature tube resistance furnace selected high temperature combustion tube, with silicon carbon rod as the heating element in the furnace coat device.

4, high temperature box-type resistance furnace with silicon carbon rod as heating element, directly in the furnace installation, high heat utilization rate.

5. This series of resistance furnace insulation materials use light foam insulation brick and aluminum silicate fiber cotton, so that the heat storage and thermal conductivity of the resistance furnace can be reduced, resulting in the reduction of heat storage in the furnace heating time, surface temperature rise is low, empty furnace loss rate is small, power consumption is also greatly reduced.

6. The controller is divided into pointer type, digital display type and microcomputer multi-band control type.

Use of heat treatment electric furnace:

1. For daily use of heat treatment electric furnace, first check the boring with no difference, furnace bottom plate, resistance wire must be in good condition.

2. During the work, disconnect the power when the workpiece is coming out of the oven, and pay attention that the workpiece or tool should not collide with or contact the resistance wire.

3. Box type resistance furnace temperature shall not exceed the rated value.

4. Before the electric furnace electrification should first close the switch, then open the control cabinet button. Switch off the control cabinet first and then pull the switch.

5. Clean the oxide and dirt of all parts of the equipment (including the lower part of furnace bottom plate) regularly every month, and repair the problems in time when found.

6. Heat treatment drying box, heating furnace, electric furnace shall not exceed their rated temperature, the rest are in accordance with this procedure.
