Luoyang HongtengIntermediate frequency induction furnace
Today, the editor of Hongteng will summarize the knowledge about the power supply of furnace installation. Power supply equipment includes high-voltage or low-voltage switchgear, intermediate frequency power supply (intermediate frequency generator set or thyristor inverter), power transfer switch, compensation capacitor and intermediate frequency control cabinet (power distribution console in front of the furnace), etc. The electrical part of large intermediate frequency furnace is also Including crucible leakage furnace alarm system. The intermediate frequency power supply is composed of two parts: the intermediate frequency power supply cabinet and the capacitor compensation frame. With the improvement of facility power, the power supply voltage of intermediate frequency power supply is also different: at present, the common ones are 380V, 575V, 660V, 750V, 950V, 1100V; the number of power supply phases is divided into three-phase, six-phase and twelve-phase. The composition of the intermediate frequency power supply cabinet: the main switch, the rectifier thyristor, the inverter thyristor, the main control board, and the smoothing reactor. The main control board is equivalent to the human brain. At present, the constant power main control board is widely used. There are two processes of wave soldering and manual soldering. The wave soldering process is stable and the failure...
When the smelting furnace is in use, the common emergencies are the penetration of the furnace and the leakage of molten iron. If no measures are taken, the copper tube of the coil will be ruptured, and the molten iron and the coolant will contact and cause an explosion, which will result in a major equipment accident or personal injury accident. This time, Hongteng editor made some analysis on the situation that caused the smelting furnace to wear through the furnace and leak molten iron. Causes of molten iron leaking through the melting furnace: 1. The molten iron cooling time is too long and the cover is formed, and it is heated and expanded again, and the lining is squeezed to cause cracks in the furnace lining. During the melting process, the molten iron penetrates from the cracks, causing it to pass through the furnace or spray from the knot cover, resulting in a blast furnace accident. 2. With the increase of furnace age, the volume of furnace lining becomes larger. The amount of molten iron in the furnace increases, and the furnace lining is thin, which can not withstand the pressure of molten iron locally, resulting in the furnace...
As a novel casting heating and melting equipment, the smelting furnace is mainly used in the iron ore industry, which brings convenience to the production of iron ore. There are many models of furnaces, which can be designed according to the needs of users. For example, exclusively for smelting steel or exclusively for smelting aluminum. Its production capacity is also designed to be flexible, depending on the size of the furnace body, it can reach 0.5t-15t per hour. The heating process of the furnace body is realized by the induction coil, and the smelting of the metal can be completed in less than an hour. The speed is very fast and the work is very stable. The medium frequency magnetic field has a magnetic stirring effect on the molten metal, which is beneficial to the uniform composition and scum. The power supply of the melting furnace adopts IGBT power devices, the output power reaches more than 90%, the heating and heat permeability are good, the temperature is uniform, and it can work continuously for 24 hours, effectively ensuring the production capacity. When in use, there is no noise during operation, which meets environmental protection standards. After the metal is smelted,...
Melting furnace is a mechanical equipment used for thermal processing in the metal processing industry. It has the advantages of good performance and reliable operation. While the market for furnaces is transparent, furnace prices vary widely. Today, the editor of Hongteng will introduce the impact of some mechanical components on the price of the melting furnace. Generally, the parts that can affect the price of the melting furnace are: 1. SCR Thyristor is one of the main components of power supply equipment. Generally speaking, the thyristor materials produced by various manufacturers are basically the same. The difference in price mainly exists in quality fluctuations. The quality of products of large-scale manufacturers fluctuates relatively. smaller. 2. Furnace shell There is a big difference in the price of furnace shells, because the difference of furnace shells can directly affect the heat transfer rate, etc. The price difference from general steel furnace shells, stainless steel furnace shells, and aluminum furnace shells is about double. 3. Copper bars and copper pipes The price difference between bronze medals and copper pipes is mainly due to the material. The type of copper, the purity of copper, etc. are all factors that affect the price difference of...
In the process of using the smelting furnace, in order to avoid accidents such as furnace penetration and leakage, safety management is very important. Below, the editor of Hongteng will analyze these common safety problems for you. The cause of the accident through the furnace 1. The molten iron cooling time is too long and the cover is formed, and it is heated and expanded again. During the melting process of the furnace lining, the molten iron penetrates out of the crack, causing it to pass through the furnace, or spray out from the knot cover, resulting in a blast furnace accident. 2. With the increase of furnace age, the volume of the furnace lining becomes larger, the amount of molten iron in the furnace increases, and the furnace lining is thin, which can not withstand the pressure of molten iron locally, which leads to the penetration of the furnace. 3. When the furnace lining is knotted, some parts do not meet the requirements or some impurities are brought in and are not found, especially ferromagnetic substances, which cause the above defects to pass through during smelting. 4. The furnace lining is rapidly cooled to produce cracks, and the molten...
When using the electric furnace, the knotting material is a very important process step. Today, Hongteng editor will introduce some good knotting material construction methods to you. First of all, we need to build the bottom of the furnace. Fill the bottom of the furnace with the asbestos cloth and add the mixed crucible material. After tamping with an air pick, the thickness is 80-100mm. Rake the surface and add another layer. 40-60mm building charge, and then tamping. Repeat these operations until the building charge reaches the specified height. (It is flush with the induction coil of the second layer at the bottom, and the thickness of the furnace bottom is 150-180mm). After the bottom of the crucible is knotted, put on the crucible mold (welded with 5-8mm thick steel plate to form the inner shape of the crucible), set the position so that the center of the crucible coincides with the center of the induction coil, and correct the center position. Place three wooden wedges at a 120-degree orientation to prevent the crucible from skewing, and place a weighted iron or heavy object in the crucible to fix it to prevent the mold from being lifted when the furnace...
