What are the operating procedures and scope of use of the intermediate frequency induction furnace? This equipment is not very familiar to ordinary people. It doesn't matter if you are not familiar with it, it only takes professional people to know how to operate it. If you want to learn this operation, you can go to Kehua to learn. 1. Operating procedures of intermediate frequency induction furnace 1. Before starting the furnace, the operator of the intermediate frequency unit should be notified to start the unit, and at the same time, check whether the furnace body, cooling water system, intermediate frequency power switch, furnace tilting machine and running track of the hoisting bag are normal, and the trench cover plate Whether it is damaged, cover it up. If there is a problem, it should be eliminated first before the furnace can be opened. 2. After the intermediate frequency unit is started, the furnace can be powered on. 3. When opening the furnace, the charge should be put into the furnace first, and the cooling water should be opened before closing the intermediate frequency power switch. When the furnace is stopped, the intermediate frequency unit can be notified to stop after the intermediate frequency power supply is disconnected. Cooling water should continue for 15 minutes. 4. The charge shall not be mixed with airtight containers, pipes or other explosives. The charge must be dry and free of water or ice or snow. When charging the charge, it is not allowed to hit it hard with a hammer, and it should be lightly placed and tapped to avoid damage to the furnace. When the burning loss of the furnace exceeds the specified limit, the furnace should be stopped for repair. 5. The tool should be placed in the designated place, and it should be baked and dried before use. 6. When smelting alloy steel and adding alloy materials, it should be clamped with pliers after preheating, slowly and in batches, and the operator's face should avoid the furnace mouth when adding. 7. When the molten steel is poured into the ladle by tilting the furnace body, the power should be cut off first, and then the machine should be slowly poured. The ladle must be baked to dry. There should be no stagnant water in the pit in front of the furnace. 8. When taking the sample, pay attention to the surrounding people, so as not to burn the steel flower. 9. When the electrical circuit is faulty, it should be repaired in time. When checking trenches, induction coils, cooling water pipes and other electrical appliances, be careful to prevent yourself and others from getting electric shock. 10. The speed of lifting and transporting the ladle should not be too fast, and the molten steel should not be overfilled (it should be at a certain distance from the edge of the ladle). If pouring with hand ladle, they should cooperate with each other when walking, do not rush to stop. If molten steel is spilled, put it down firmly and do not throw the bag. 11. If it is found that the water is stopped, the furnace is leaking, the insulation layer of the induction coil is broken and water is leaking, the furnace should be stopped immediately for maintenance. 12. When dismantling the intermediate frequency furnace of more than half a ton, it is necessary to take care of it from top to bottom and cooperate with each other. There must be a special person to guide when dismantling and assembling. 13. After the furnace is stopped, the main power switch must be cut off. Leave after closing the water valve. 2. What are the application scope of intermediate frequency induction furnace? Intermediate frequency induction furnaces are widely used in the smelting of non-ferrous metals [mainly used in the smelting of ferrous materials such as steel, alloy steel, special steel, cast iron and non-ferrous metal materials such as stainless steel and zinc, as well as the smelting of non-ferrous metals such as copper and aluminum. It can heat up and keep warm, and can perform double operation with the blast furnace. ], forging heating [for bar, round steel, square steel, steel plate and other profiles for diathermy, temperature compensation, blue quenching and blanking on-line heating, local heating, on-line forging of metal materials (such as gears, half shaft connecting rods, bearings) (such as precision forging), extrusion, hot rolling, heating before shearing, spray heating, hot assembly, and overall quenching and tempering, annealing, and tempering of metal materials. ] Heat treatment [mainly for shafts (straight shafts, variable diameter shafts, camshafts, crankshafts, gear shafts, etc.); gears; sleeves, rings, discs; machine tool screws; guide rails; planes; ball joints; hardware tools, etc. Surface heat treatment of various mechanical (automobile, motorcycle) parts and overall quenching and tempering, annealing and tempering of metal materials], etc. The above is the knowledge about the operation procedures of the intermediate frequency induction furnace that Kehua introduced to you today. After the above learning, I believe everyone knows how to operate. That's it for today's sharing.
