Luoyang HongtengIntermediate frequency induction furnace
Induction furnace is a kind of electric furnace that uses induction electric heat effect to heat or melt the material. The basic components of the induction furnace are induction loops wound with copper tubes. AC voltage is applied to both ends of the induction coil to generate alternating electromagnetic fields, conductive materials are placed in the induction coil, eddy current is generated in the materials due to electromagnetic induction, and electric energy is converted into thermal energy under the action of resistance to heat the materials; Therefore, it can also be considered that induction heating is a direct heating type of resistance heating. Induction heating is characterized by uneven electric heating power (current distribution) converted in the heated material, with the largest surface and the smallest center, which is called the skin effect. In order to improve the electric heating efficiency of induction heating, the power supply frequency should be appropriate. Small smelting furnaces or high-frequency electricity should be used for surface heating of materials, while large smelting furnaces or medium-frequency or power-frequency electricity should be used for deep heating of materials. The induction coil is a load with considerable inductance, and its power factor is generally very low. In...
Induction heating furnaces are also called preheating furnaces, reheating furnaces Online temperature measurement system. To ensure accurate control of the temperature of small billets and continuous cast billets during the heating process, infrared thermometers are generally arranged at the inlet and outlet of the industrial heating furnace. In addition, to compensate for the time difference in temperature measurement by the pyrometer and to improve control sensitivity, furnace body detection devices are installed at the inlet and outlet of each group of furnaces to make the heater more sensitive and reliable when maintaining low and high power switching. Increase the sorting system, in order to guarantee that the temperature of the heated billets is up to standard, you can add a sorting system at the exit of the heating furnace so that the billets with substandard temperature can be screened.

Continuous casting machines mainly include steel ladle and ladle rotary table – intermediate ladle – lead ingot device – crystallizer and crystallizer vibration device – fan section – billet cutting device (such as flame cutting machine or hydraulic shear and swing shear). The middle ladle plays the role of buffering and purifying the steel liquid, the capacity is generally 20% to 40% of the capacity of the steel ladle, the more the number of streams in the CCM machine, the larger the capacity. The crystallizer is the “heart” of the CCM continuous casting machine, requiring good thermal conductivity, structural rigidity, wear-resistance, and ease of manufacture and maintenance characteristics, generally made of forged copper or cast brass, its outer wall through the water forced uniform cooling. CCM casting machine is preceded by steelmaking equipment. Steelmaking equipment is used to produce steel liquid, the main method of steelmaking is the oxygen converter method of steelmaking. There is also the use of an industrial induction furnace for melting steel from scrap steel. The continuous casting machine process is followed by rolling, for example, the steel rebar production line: the main processes are induction heating furnace – roughing rolling mill – continuous rolling mill...
1. The metal melting furnace process is more stable, and the castings have higher mechanical strength. In the induction furnace can be melted in various compositions of iron, due to the melting process of oxidation lossless, and can be more convenient to adjust the composition and temperature of the iron liquid, the final quality of the iron liquid obtained is more stable. In recent years, new processes for the production of high-strength and low-stress castings have emerged abroad. The method is to use 40% to 80% of scrap steel in the ingredients, first obtain low-carbon raw molten iron, then heat it to 1450°C for decarburization, and make the chemical composition reach the value specified in the process, and then overheat the molten iron to keep the temperature at 1500～1550℃ for 10～30min, and strictly control the crystallization supercooling degree of the molten iron. 2. The use of induction furnaces for melting non-ferrous metals can reduce melt burnout or achieve oxidation-free melting, such as aluminium induction melting furnaces, copper induction melting furnaces and zinc melting furnaces. 3. The use of induction melting furnaces reduces environmental pollution. Because the induction electric furnace does not have energy carriers of combustion products, the discharge of...
Option A: The raw material is scrap, which needs to start with scrap steel melting. The first step is to melt the scrap steel in an induction melting furnace; the second step is to cast the billet through a column mold or CCM; the third step is to reheat the billet in an induction heating furnace, and finally to enter a horizontal rolling mill or continuous rolling mill. Option B: The raw material is billet, which we can heat directly in a reheating furnace and then feed into a rolling mill to be rolled into a rebar or other profiles of steel. As you can see, the billet-to-rebar production option saves more power and investment, so if you don’t want to invest too much in the first stage or don’t have enough power, then option B small mini rolling mill from billet to steel rebar is a better option. And if we have a lot of raw scraps and want a larger capacity rebar production line, plan A would be better. In general, plan A is more thermally efficient because the billet is still hot when it has just been cast from CCM and this will save electricity. Some continuous...
Normally there are 3 steps for steel bar production line: 1. Melting scrap steel as liquid and casting billet, the equipment in this step we need is: Industrial induction melting furnace(melting steel as liquid), closed water cooling tower(cooling the melting furnace), transformer(transfer the electricity from high side voltage to equipment voltage), and billet mold or CCM continuous casting machine ( to casting standard billet size) 2. Heating the billets to 1250 degrees. Here we need: Billet heating furnace(reheating billet) and closed water cooling tower(cooling the induction heating furnace) 3. Processing hot billets to steel rebar, here we need Hot rolling mill group(rough rolling mill, continuous rolling mills), auxiliary equipment like roller conveyor, Shear, cooling bed, and packing table, etc Here are some videos of our products for your understanding and reference, hope they can bring you help. https://www.youtube.com/watch?v=9bI_8R81ELs
