Before tempering the workpiece into the furnace, power to the distribution box, turn back the trolley out, check whether the instrument is normal, whether the instrument is normal (set temperature value), fan motor, heater, etc., whether intact. When loading, it is required to place evenly and not tilt. After entering the furnace, the height should not be connected with the power supply in the furnace, the spacing should be 100mm. When the car enters the furnace, go slowly, check whether the car enters the furnace smoothly, whether the power line is blocked, close the furnace door after entering the furnace, heat the fan motor, adjust the temperature, and correct the temperature with a thermometer.
After tempering, first close the heating switch, and then close the fan motor, and then open the door, the car out. When the product is finished in the loading and unloading furnace, check whether the thermocouple can be inserted into the furnace (thermocouple is the data value of temperature measurement), do not touch the thermocouple (the workpiece is not allowed to contact the thermocouple). The man on duty must check the stove every hour during his work. Turn off the switch to extinguish the fire when the circuit fails or fires due to a fault. When the furnace is on fire, immediately open the furnace door and pull out the car, turn off the switch to extinguish the fire. When the electrical system fails, it is repaired by an electrician. Non-electrical personnel are prohibited to repair by themselves. Tempering furnace is a periodically running tempering furnace, which is used to stop tempering ordinary metal parts after quenching, as well as the quenching, annealing and aging of aluminum alloy die castings, pistons, aluminum plates and other light alloy parts.
