What is the working principle of the intermediate frequency heating furnace? What should be paid attention to when using the intermediate frequency heating furnace? -Kehua

When processing metal, it must be heated first. Among all kinds of heating equipment, intermediate frequency heating furnace is the most widely used. It has the advantages of fast heating speed and low energy consumption. Now Kehua will tell you what the working principle of the intermediate frequency heating furnace is, and what should be paid attention to when using the intermediate frequency heating furnace? Working principle of the intermediate frequency heating furnace The working principle of the intermediate frequency heating furnace Eddy current and generate heat to achieve the purpose of heating the material. The intermediate frequency heating furnace adopts 200-2500Hz intermediate frequency power supply for induction heating, smelting and heat preservation. The intermediate frequency electric furnace is mainly used for smelting carbon steel, alloy steel, special steel, and can also be used for smelting and heating of non-ferrous metals such as copper and aluminum. The equipment is small in size, light in weight, high in efficiency, low in power consumption, fast in melting and heating up, easy to control the furnace temperature, and high in production efficiency. The working principle of the intermediate frequency heating furnace What should be paid attention to when using the intermediate frequency heating furnace 1. Before starting the furnace, check whether the electrical equipment, water cooling system, inductor copper tubes, etc. are in good condition, otherwise it is forbidden to open the furnace. 2. If the melting loss of the furnace exceeds the regulations, it should be repaired in time. It is strictly forbidden to smelt in the crucible with excessive melting loss. 3. A special person should be responsible for power transmission and furnace opening, and it is strictly forbidden to touch sensors and cables after power transmission. Kehua reminded everyone that those on duty should not leave their posts without permission, and pay attention to the external conditions of the sensor and the crucible. 4. When charging, it is necessary to check whether there are inflammable, explosive and other harmful substances mixed in the charge. If it is, it should be removed in time. It is strictly forbidden to directly add cold material and wet material into the molten steel. After the molten liquid is filled to the upper part, it is strictly forbidden to add large pieces of material. , to prevent capping. 5. It is strictly forbidden to mix iron filings and iron oxides when repairing the furnace and pounding the crucible, and the pounding crucible must be dense. 6. The pouring site and the pit in front of the furnace should be free of obstacles and water, to prevent molten steel from falling to the ground and exploding. 7. The molten steel is not allowed to be too full. When pouring the hand ladle, the two should cooperate in the same way. The walking should be stable, and emergency stops are not allowed. 8. The medium frequency generator room should be kept clean. It is strictly forbidden to bring inflammable and explosive materials and other sundries into the room, and smoking is prohibited indoors. The working principle of the intermediate frequency heating furnace is not very complicated, but its working efficiency is very high. In the process of using the intermediate frequency heating furnace, you also need to pay attention to the above matters.
