A trip is a way for a power supply to protect itself when something goes wrong with a circuit. At this time, figuring out the faults in the circuit and solving these problems can make the circuit and power supply work normally. Sometimes, users will trip while using the electric furnace. Why does this happen? Today, the editor of Hongteng will introduce to you the reasons for the tripping of the electric furnace. 1. Overcurrent protection, one is the phenomenon that the multi-current protection circuit operates due to the low setting value of primary overcurrent protection or secondary overcurrent protection. At this time, the current protection setting value should be amplified. The other is the phenomenon that the overcurrent protection circuit operates due to circuit interference. You can try to add a smoothing reactor to the circuit to weaken the circuit interference. 2. The damage of the potentiometer of the electric furnace or the voltage failure of the potentiometer usually leads to the occurrence of this phenomenon. When this phenomenon occurs, the potentiometer should be replaced in time. 3. The load is greatly increased, but the DC equivalent resistance of the load is too small, resulting in a low DC...
As a kind of intermediate frequency heating and smelting equipment, induction furnace is mainly used for heat treatment of metals in the metallurgical industry. Let us briefly introduce the induction furnace from the composition, working principle and specific application. 1. Composition of induction furnace Aluminum shell structure: intermediate frequency power supply cabinet, compensation capacitor bank, aluminum shell furnace body and water-cooled cable, reducer, tilting furnace operation box, etc. Steel shell structure: intermediate frequency power supply cabinet, compensation capacitor bank, steel shell furnace body, magnetic yoke and water cooling cable, hydraulic station, tilt furnace control box, etc. 2. Working principle Induction furnace heating metal mainly uses the principle of electromagnetic induction heating. The current passes through the inductor coil to generate a magnetic field, and the magnetic field cuts the metal in the coil to generate eddy current and the metal itself heats up for heating. It is widely used in pre-forging heating, steel bar quenching and tempering heating and metal smelting. 2. Working characteristics (1) The induction furnace has a wide range of applications and can be used for the smelting of steel, stainless steel, copper, aluminum, gold, silver and other materials. (2) The use of intermediate frequency smelting technology...
When using the furnace, sometimes the induction coil is blocked, which affects the production capacity of the entire production line. Today, Hongteng editor will analyze the reasons and solutions for the blocking of the induction coil of the furnace. There are two common reasons. One is a foreign body blockage. The cooling water source used by the user sometimes directly extracts the river water as the cooling water for the electric furnace. There are many foreign objects in the river water. Therefore, when extracting and using the river water, the foreign objects can easily block the induction coil, resulting in blocked or blocked waterways. Another is limescale clogging. The water source used for cooling is basically natural water with relatively high hardness, and the smelting furnace will generate high temperature when it is working. At this time, when water is used for cooling, it is easy to produce scale attached to the inside of the induction coil copper tube. The composition of scale is basically calcium carbonate and magnesium hydroxide. If it is not treated for a long time, these deposits will become more and more hard. Finally, the sediment will not only block the coil and cause the water...
The furnace lining plays a very important role in the operation of the melting furnace, and there are many types of furnace linings. Common furnace linings include acidic furnace lining, neutral furnace lining, and basic furnace lining. So, is there any good way to choose suitable furnace lining materials? The editor of Hongteng made some summaries for you today. 1. The furnace lining must have a certain high temperature strength In the smelting process, the furnace wall is subject to the impact force of the metal charge, the static pressure of the molten metal, the force of the electromagnetic stirring of the molten metal, the temperature difference stress, etc., which will affect the service life of the lining of the smelting furnace, so the lining material should have A certain high temperature strength, no cracking and erosion resistance under the action of various forces. 2. The refractoriness of the furnace lining should be excellent When the smelting furnace is in operation, the temperature of molten steel can reach 1700℃ or above, and the temperature of molten iron can reach above 1500℃. Therefore, the furnace lining material should have excellent refractoriness, and the furnace lining material that meets the melting temperature...
When the induction furnace is working, sometimes the power of the equipment does not meet the standard, which will increase the time for melting and processing of the furnace body and affect the efficiency and quality of equipment production. So, do you know the factors that affect the power of the induction furnace, and is there any way to increase its power? Today we will give you a brief summary. 1. The rectifier part of the induction furnace is not properly adjusted, the rectifier tube is not fully turned on, and the DC voltage does not reach the rated value. At this time, the trigger circuit of the induction furnace rectifier circuit should be adjusted in time. 2. If the intermediate frequency voltage value is adjusted too high or too low, it will affect the power output. At this time, the intermediate frequency voltage needs to be adjusted to a suitable value. 3. Improper adjustment of the cut-off and cut-off values of induction furnace operation will also reduce the power output of the furnace body. At this time, the cut-off and cut-off values of the induction furnace should be re-adjusted. 4. Only the supporting intermediate frequency power supply and furnace...
