Large vacuum heat treatment furnace detailed introduction:
Large vacuum heat treatment furnace vacuum heat treatment is a comprehensive technology that combines vacuum technology and heat treatment. It means that all or part of the heat treatment process is carried out under vacuum. The vacuum heat treatment furnace has high thermal efficiency, can achieve rapid heating and cooling, can achieve no oxidation, no decarburization, no carburization, can remove phosphorus chips on the surface of the workpiece, and has the functions of degreasing and degassing, so as to achieve the effect of surface brightening and purification.
Safe operation of large vacuum heat treatment furnace
1. Vacuum heat treatment furnace is an advanced heat treatment equipment that has been greatly developed in recent years. The workpiece is heated and cooled in an ultra-low pressure space. It has the advantages of good quality, energy saving, safety and less pollution.
2. The heating element of the vacuum furnace uses low-voltage electricity, but the power supply voltage is still 380V, and safe electricity is still required during operation.
3. When manufacturing a vacuum furnace, it should be ensured that there is no air leakage or water leakage. The seals of the vacuum furnace body and furnace cover are made of rubber parts, so they need to be cooled with a water interlayer. If water leaks into the furnace, the furnace temperature will be very high and may cause an explosion. The surface oil stains of the workpieces processed by the vacuum furnace should be cleaned, and the oil vapor in the quenching oil tank should be prevented from entering the furnace. These oil vapors will form an explosive atmosphere when mixed with air, and an explosion will occur once there is an open flame or electricity is turned on. Therefore, the furnace door should be closed after the vacuum furnace is loaded, and the furnace chamber should be evacuated before it can be powered on for heating.
