What is the use of high-temperature furnace note in the room? High temperature resistance furnace is the use of electric current in the furnace heating element or heating medium heat, thereby heating the material of the workpiece or industrial furnaces. Industry resistance furnace divided into two categories, cycle furnace operation and continuous furnace operation, high-temperature resistance furnace belongs to a high-temperature furnace, there are unique characteristics of simple structure, temperature uniformity, easy to control, good quality heating, no smoke, no noise, etc., but a higher fee. High temperature resistance furnace high temperature furnace operations should strictly follow safety procedures to do to ensure the safety of personnel and avoid the furnace, damaging the workpiece.
First, the work before the process
1. Check the furnace is clean, clean up debris, make sure the furnace is clean.
2, check the furnace wall, furnace floor for cracks and other damage.
3, resistance and thermocouple lead wire fastening rod installation, check the meter is normal.
4. Check resistance furnace door switch is flexible.
5, to ensure that the normal, they began to put the workpiece.
Second, the work flow
1. Make sure the power is off when you release the workpiece.
2, gently to avoid smashed heating element, furnace floor and the like;
3, non put wet workpieces, and electric furnace heating elements should be kept a distance of 50-70mm; workpiece should be placed neatly, shall not be stacked too high in order to avoid damage the thermowell
4, check a variety of instrumentation work equipment and, if abnormal, timely maintenance.
5, when the furnace temperature above 700 ℃, are not allowed to open the door to cool or baked, so as to avoid quenching furnace shortened life expectancy.
Third, the flow of work.
1. Cut off the power supply
2, gently workpiece, make sure not to damage the furnace and artifacts.
3. Replace the furnace, according to the above procedure is repeated.
4, within clear theory debris to ensure clean.
5, pay attention to routine maintenance work.
6, attention to indoor air circulation
