Luoyang HongtengIntermediate frequency induction furnace
The intermediate frequency furnace is an induction heating equipment. As one of the mainstream heating equipment in the machinery industry, it has many functions. In the forging industry, the intermediate frequency furnace can be used for pre-forging heating; in the foundry industry, the intermediate frequency furnace can be used for metal melting; in the heat treatment industry, the intermediate frequency furnace can be used for quenching and tempering heating of metals. So how can we buy the intermediate frequency furnace equipment that suits us? Today, the editor of Hongteng will give you some suggestions on purchasing an intermediate frequency furnace. 1. First of all, determine what is the purpose of using the intermediate frequency furnace. Is it metal heating? Is it quenching and tempering heat treatment? Or metal smelting? 2. You need to determine what the material of the metal to be heated by the intermediate frequency furnace is. For example: steel, iron, aluminum, copper, stainless steel and alloy steel. 3. Determine the temperature of each process link of the intermediate frequency furnace. Including: heating temperature, annealing temperature, quenching temperature, forging temperature, and melting temperature. In this part, you can communicate with the manufacturer of the intermediate frequency furnace, such...
As a metal smelting equipment, the medium frequency induction furnace is favored by many foundry manufacturers because of its flexible and simple operation, easy to control the smelting quality, fast smelting speed and high production efficiency. When the intermediate frequency furnace is in use, the sound emitted by the machine can be used as a basic condition for judging the operating state of the intermediate frequency furnace. So, how do we judge the working state of the intermediate frequency furnace from the sound of it? Luoyang Hongteng Xiaobian will introduce it to you. 1. The normal operating state of the intermediate frequency furnace: When the intermediate frequency furnace is working, the frequency of the power supply will naturally cause vibration and produce a whistling sound. This sound indicates that the intermediate frequency furnace is in good working condition and operates normally. This is the sound that intermediate frequency furnace production personnel and maintenance personnel love to hear. 2. Power supply noise of intermediate frequency furnace: When the intermediate frequency furnace is running, the reactor coil in the power supply emits noise, and it is abnormal to have such a sound. The cause may be that the coil fixing bolts are...
The SCR is the main part of the intermediate frequency furnace and the heart of the intermediate frequency power supply. Its correct use is crucial to the operation of the intermediate frequency electric furnace. SCR is generally used in industrial electric furnaces, such as intermediate frequency melting furnaces, intermediate frequency heating furnaces, etc. It is normal to occasionally damage a few thyristors during the use of an intermediate frequency induction furnace. If silicon is frequently burned, it will cause alarm. When the intermediate frequency furnace is working, the working current of the thyristor is several thousand amperes, and the voltage is usually one or two thousand volts. Good main control board protection and good water cooling conditions are necessary. The radiator structure of the thyristor: water-cooled cavity + multi-copper column support. If the circulating water is too hard, the scale will form inside the water cavity, resulting in poor heat dissipation of the machine; if the water cavity enters leaves and other sundries, it will also cause poor water flow. Overload characteristics of thyristor: The damage of thyristor is called breakdown. Under normal water cooling conditions, the current overload capacity can reach more than 110%; the factory test temperature of...
Many customers often ask us the difference between hot rolled steel and cold rolled steel. Fundamentally, there are some differences between these two metals. The difference has nothing to do with product specification or grade, but with the way, the factory processes these metals. If the temperature of the metal is above its recrystallization temperature (over 1700 degrees Fahrenheit), the process is called hot rolling. At this temperature, steel can be easily shaped and shaped and can be made to larger sizes. Generally, hot rolled steel is cheaper than cold rolled steel because it is usually manufactured without any processing delay. Hot-rolled production lines, such as rebar production lines, angle steel production lines, deformed bar production lines, remanufacturing of scrap steel bars, hot rolling steel bar, angles are generally used in welding and construction industries, such as the manufacture of rails and I-beams. Hot rolled steel is used when precise shapes and tolerances are not required. If the temperature of the metal is below its recrystallization temperature, the process is called cold rolling. Essentially, cold-rolled steel is hot-rolled steel that has been further processed. Steel is processed in a cold rolling mill, where the material is cooled (at room temperature)...
When shopping for a new industrial furnace, you will probably see a number of different brand names and several popular features. But there’s something important you should know. In China, induction furnace manufacturers are concentrated in Luoyang, so you will want to say, which one should Luoyang choose for so many furnace manufacturers? 1.Is it a real factory? In order to get a better price 2. In this industry, whether it is in the head position or not, the manufacturers in the head position usually have better service in order to maintain their position. 3. Whether they have the ability of independent research and development, manufacturers committed to independent research and development usually have better scientific and technological standards. 4. What percentage of products are exported? Manufacturers who mainly export are better able to understand the demand abroad. Here Luoyang Hongteng brand is your best choice. We are a real factory, with more than 20years experience. we are at the top in this machinery industry. We have the ability to develop independently. 80% of our products are exported. And the price, we are super reasonable. Here are some videos of our products for your understanding and reference, hope they can...
(1) Electromagnetic induction heating. Due to the different heating methods, the induction furnace does not have the graphite electrodes necessary for arc heating, and there is no local overheating area under the arc, thus eliminating the possibility of electrode carbonization. Electric induction furnaces can smelt steels and alloys with a very low carbon content that are difficult to smelt in electric arc furnaces, creating favorable conditions for obtaining products with low gas content. (2) There is a certain intensity of electromagnetic stirring in the melting pool. The metal stirring caused by electromagnetic induction promotes uniform composition and temperature, and the inclusions in the steel merge, grow, and float. The burning loss of alloying elements in the induction furnace smelting process is less, so the predicted composition is more accurate, which is conducive to composition control and shortening the smelting time. (3) The specific surface area of the melting pool is small. This is beneficial to reduce the loss of easily oxidizable elements in the molten metal pool and reduce the inhalation, so the induction furnace creates relatively good conditions for smelting high-alloy steels and alloys, especially those containing elements such as titanium, aluminum, or boron. . However, it is easy...
