80kw 1200º C Pit-Type Resistance Furnace for Heat Treatment

Introduction
Pit furnace is a periodic work furnace, suitable for rods, long shaft parts of the heat treatment. The structure of the pit furnace is: the furnace body is a cylindrical deep well, the workpiece by the special crane vertical into the furnace heating



Precautions

1) Check the furnace door or furnace cover next to the city limit switch, should ensure that the door or furnace lid after the start, the main circuit power.

2) Pit furnace should be used before the power connector to ensure good contact. Insulation of power cord meets requirements.

3) control the atmosphere resistance furnace equipped with gas flow meter and pressure gauge, to indicate accurate and sensitive.

4) access to the flammable atmosphere of the resistance furnace, to have the furnace temperature below 760 ° C alarm and the necessary interlock to avoid the explosion.

5) The grounding bolt of the furnace body should be firm and reliable.

6) Water-cooled well-type furnace should be installed water temperature, water pressure and flow relay, there is abnormal circumstances that cut off the main circuit power supply, and issued an alarm signal.

7) control atmosphere furnace explosion-proof safety device to be flexible and reliable.

8) outside the furnace shell exposed electric heating body to have a safe and reliable protective cover.
