Furnace safe operating procedures

The use of high-temperature furnace heating current to the furnace heating elements or heating medium, and thus the workpiece or industrial furnace for heating materials. Industry resistance furnace divided into two categories, periodic furnace operation and continuous operation furnace, tube furnace is a high-temperature furnace, a unique feature has a simple structure, temperature uniformity, easy to control, heating quality is good, no smoke, no noise, etc., but with higher fees. Use high-temperature tube furnace furnace should strictly follow safe operating procedures to do, to ensure the safety of personnel and to avoid the furnace, the workpiece damage.
First, before work processes
1, check the furnace is clean, clean up debris to ensure the furnace clean.
2, check the furnace wall, floor furnace for cracks and other damage.
3, the resistance wire and thermocouple leads to the installation of fastening rods, check the meter is normal.
4, check the resistance furnace door switch is flexible.
5, to ensure that the normal, they began to put the workpiece.
Second, the work flow
1, put the workpiece to ensure that power is off.
2, gently so as not smashed heating elements, furnace floor, etc.;
3, put a wet piece is strictly prohibited, furnace heating of the workpiece and the heating element should be kept 50-70mm distance; workpiece should be placed neatly, not stacked too high in order to avoid damage the thermowell
4, the work examine the various instrumentation and, if abnormal, timely maintenance.
5, high-temperature furnace at 700 ℃ or more, are not allowed to open the door to cool down or baked, so as to avoid quench furnace shortened lifespan.
Third, the work process.
1, cut off the power supply
2, gently work, make sure not to damage the furnace and the workpiece.
3, replace furnace, according to the above procedure is repeated.
4, clear theory within the debris to ensure clean.
5, pay attention to routine maintenance work.
