Summary. Hello kiss is happy to answer for you, kiss check whether there is water leakage, whether the bottom of the furnace has been repaired, the intermediate frequency furnace with a bad grounding will have the feeling of numb hands is electromagnetic induction heating, and the charge (molten steel) will produce induced current, otherwise the charge will not melt. The operator or the person who carries the molten iron will feel numb by the electricity.

First of all, the operator must wear insulated work shoes, the ground should be kept dry, and secondly, the position of the operator station should be covered with rubber mats (the rubber skin in the shot blasting machine is the best, the thickness is enough) or thick wooden boards. I hope mine can help you. Have a great day

1. Before opening the furnace, check whether the electrical equipment, water cooling system, inductor copper pipe, etc. are in good condition, otherwise it is forbidden to open the furnace.

2. The furnace melt damage should be repaired in time if it exceeds the regulations. It is strictly forbidden to melt in a crucible that is too deeply damaged.

3. There should be a special person responsible for power transmission and furnace opening, and it is strictly forbidden to contact the sensor and cable after power transmission. Those on duty are not allowed to leave their posts without authorization, and they should pay attention to the external conditions of the sensors and crucibles.

4. When loading, it should be checked whether there are flammable and explosive harmful substances mixed in the charge, if there is any, it should be removed in time, it is strictly forbidden to add cold materials and wet materials directly into the molten steel, and it is strictly forbidden to add large pieces of material after the molten liquid is filled to the upper part to prevent the lid.

5. It is strictly forbidden to mix iron filings and iron oxide when repairing the furnace and pounding the crucible, and the crucible must be dense.

6. The pouring site and the pit in front of the furnace should be free of obstacles and no stagnant water to prevent the molten steel from falling to the ground.

7. The molten steel is not allowed to be overfilled, when the hand bag is poured, the two should cooperate consistently, walk smoothly, and do not stop in a hurry.

8. The medium frequency generator room should be kept clean, and it is strictly forbidden to bring flammable and explosive materials and other sundries into the room, and smoking is prohibited indoors.

Using the principle of electromagnetic induction, eddy currents are generated in the workpiece placed in the induction coil, so that the workpiece is heated and heated to the required temperature. The device uses series resonance or parallel resonance, so the power factor is high. Compared with the traditional heating method, it has the advantages of high efficiency and low pollution.

The equipment has a wide range of applications in industries such as forging and metal heat treatment.

(1) High melting efficiency, good power-saving effect, compact structure and strong overload capacity.

2) The temperature around the furnace is low, the smoke and dust are less, and the working environment is good.

3) The operation process is simple and the melting operation is reliable.

4) The metal composition is uniform.

5) Fast melting and heating, easy control of furnace temperature, high production efficiency.

6) The furnace has a high utilization rate and is convenient to replace the variety.

7) The long arc yoke shields the magnetic flux leakage and reduces the external magnetic resistance, the magnetic flux leakage at both ends of the shielded coil, and the inner side of the yoke with an arc cross-section is seamlessly attached to the outer wall, which increases the effective permeability area and makes the coil obtain better support. The unique positive and reverse rotation coils greatly improve the efficiency of the system. Fast heating speed, high production efficiency, less oxidation and decarbonization, saving material and forging die costs.

Because the principle of intermediate frequency induction heating is electromagnetic induction, the heat is generated in the workpiece, and ordinary workers can carry out continuous work of forging tasks ten minutes after going to work with intermediate frequency electric furnace, and there is no need for professional workers of the furnace to burn and seal the furnace in advance. There is no need to worry about the waste of heated billets in the coal furnace due to power outages or equipment failures. Due to the fast heating rate of this heating method, there is very little oxidation, and at least 20-50 kg of steel raw materials per ton of forgings can be saved compared with coal-fired furnaces, and its material utilization rate can reach 95%.

Because the heating method is heated evenly and the temperature difference between the core surface is very small, the life of the forging die is greatly increased in forging, and the roughness of the surface of the forging is less than 50um.

The working environment is superior, the working environment of workers and the image of the company are improved, no pollution, and low energy consumption.

Compared with the coal furnace, the induction heating furnace will no longer be roasted and smoked by the coal furnace under the scorching sun, and it can meet the requirements of the environmental protection department, and at the same time establish the company's external image and the future development trend of the forging industry. Induction heating is the most energy-efficient heating method in electric heating furnaces, heating from room temperature to 1100 tons of forgings, and the power consumption is less than 360 degrees.

The heating is uniform, the temperature difference between the core surface is very small, and the temperature control accuracy is high.

Induction heating: The heat is generated in the workpiece, so the heating is uniform, and the temperature difference between the core surface is very small. The application of temperature control system can achieve precise control of temperature and improve product quality and pass rate.

Medium frequency induction furnace heating device has the advantages of small size, light weight, high efficiency, excellent thermal processing quality and favorable environment, and is rapidly eliminating coal-fired furnaces, gas furnaces, oil-fired furnaces and ordinary resistance furnaces, which is a new generation of metal heating equipment.

The intermediate frequency furnace is the main equipment of the casting, forging and heat treatment workshop, and the stability, reliability and safety of its work are the guarantee for the normal and stable operation of the casting, forging and heat treatment production line of assembly operation.

1. Before opening the furnace, the operator of the intermediate frequency unit should be notified of the starter group, and at the same time, the furnace body, cooling water system, intermediate frequency power switch, tilting machinery and lifting bag running track should be checked to see if the furnace body, cooling water system, intermediate frequency power switch, tilting furnace machinery and lifting bag running track, etc. are normal, and whether the trench cover is defective and covered. If there is a problem, it should be eliminated before the furnace can be opened.

2. After the intermediate frequency unit is started, the power can be sent to open the furnace.

3 When opening the furnace, you need to put the charge into the furnace first, open the cooling water, and then close the intermediate frequency power switch. When the furnace is stopped, the intermediate frequency unit can be notified to stop only after disconnecting the intermediate frequency power supply. The cooling water should continue to be kept for 15 minutes.

4. The charge shall not be mixed with closed containers, pipes or other easy materials. The charge must be dry and free of water or ice or snow. When filling the charge, it is not allowed to hit it with a hammer, but it should be gently placed and knocked to avoid damaging the furnace. When the burning loss and thinning of the furnace exceeds the regulations, the furnace should be stopped for repair.

5 The tool should be placed in the designated place and should be baked and dried in advance when used.

6. When adding alloy materials to alloy steel, it should be clamped with pliers after preheating, slowly and in batches, and the operator's face should be avoided from the furnace mouth when joining.

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 machinery should be manipulated to pour it slowly. The ladle must be baked and dried. No stagnant water is allowed in the pit in front of the furnace.

8. Pay attention to the surrounding people when taking samples, so as not to burn people.

9. When the electrical circuit is faulty, it should be repaired in time. When inspecting trenches, induction coils, cooling water pipes and other electrical appliances, pay attention to prevent electric shock to yourself and other personnel.

10. The hoisting ladle should not be too fast, and the molten steel should not be overfilled (it should be a certain distance away from the ladle edge). If you use hand to lift the bag and pour, you should cooperate with each other when walking, and do not rush to stop and go. If molten steel is spilled, it should be put down steadily, and the bag is not allowed to be thrown.

11. When it is found that the water is stopped, the furnace is leaking, the induction ring insulation layer is broken and the 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 each other, cooperate with each other, and have a special person to command when disassembling and assembling.

13. After the furnace is stopped, the main switch of the power supply must be cut off. Close the water valve before leaving.
