Luoyang HongtengIntermediate frequency induction furnace
Price: Vertical casting molds are more expensive. Open mold is cheaper. Quantity: Small melting furnaces are generally equipped with 1-4 vertical casting molds; The number of open molds is calculated according to the steel melting furnace output. Weight of molten steel per batch/weight of billet = number of molds required. Structure: The structure of the billet vertical casting mold is more complicated. The outer shell is ductile iron, and the inner crystallizer is a copper tube, needs water cooling. There are mechanical lever that can release the billet. In addition, considering the uniformity of the billet during the casting process, the Vertical mold is better equipped with a vibrating platform. Open billet mold, made of nodular cast iron, simple structure, manual demoulding, no maintenance, no water cooling, convenient operation, low cost In summary, it is generally recommended to consider the open billet mold for a small casting line of 1-3T. The size of the billet can also be customized for the open mold. The section shape of the open mold is trapezoidal, and the length of the upper edge is different from the length of the bottom. Vertical casting mold: The section of the cast billet is also trapezoidal. For...
The induction coil of Luoyang Hongteng’s electric induction furnace, i.e. the induction furnace coil, is made of a rectangular copper tube with the purity of 99.98% T2 copper tube and wall thickness of 6㎜ wounds on a special mold, with turn spacing error no more than 2mm, and the coil group is welded and then treated with stress cancellation. The upper and lower parts of the induction coil are equipped with stainless steel water-cooling rings to ensure that the furnace lining is heated evenly during the process of metal melting and metal heating. The upper and lower ends of the electric furnace coil need to be equipped with a Faraday short-circuit ring to fully absorb the magnetic flux leakage from the upper and lower ends to prevent the induction furnace body from heating up. The induction electric furnace body is connected to the electricity using a high-quality water-cooled cable with a large cross-section, and the lead-in line is in the form of a side lead-in line. The coil pressing device uses a stainless steel rod to pull up and down. The coiling water main pipeline has pressure, differential pressure, and temperature protection at the same time to ensure the water...
Thyristors: The quality of thyristors used by various manufacturers generally varies. A good quality thyristor has good temperature sensitivity, fast response, and a low failure rate. So a good quality melting furnace should choose thyristors from well-known manufacturers with reliable quality and stable performance. The power cabinet of the induction furnace: the size and specifications of the power cabinet of regular manufacturers are standard. The reactor is placed inside the power cabinet. The induction furnace power supply of regular manufacturers is equipped with a low-voltage switch, the user does not need to configure the voltage switch cabinet. Some informal manufacturers, however, do not install low-voltage switches inside the power supply. Invariably, this increases the cost to the user. Capacitors for medium frequency induction furnaces: The capacitor cabinet for reactive power compensation must be equipped with a sufficient number of capacitors. And choose capacitors from regular manufacturers. Reactors: The main material of the reactor is silicon steel sheets, and new products from regular manufacturers should be chosen, and recycled second-hand silicon steel sheets should not be used. Water pipe clamps: In the IF melting furnace sets, there are a large number of water pipe connections. High-quality melting furnaces should use stainless...
Depending on the materials, the main materials presented in this article are induction furnace shells, magnetic yokes and copper tubes. Regarding the choice of aluminium shell furnace housing, a high-quality aluminium shell furnace casing should have sufficient weight standard, for example, a standard 1-ton aluminium shell furnace casing is a cast aluminium alloy with a weight of 400Kg and a thickness of 40mm. The choice of magnetic yoke: the same model of steel shell furnace magnetic yoke selection is different, the price difference is very large, general high-quality steel shell induction furnace should choose high permeability of cold-rolled silicon steel sheet, silicon steel sheet in 0.3 mm, super thick structure, concave surface and induction coil of the same outer arc, so that the magnetic yoke can be close to the side of the induction coil, combined with the coil outward dispersion of magnetic field lines, magnetic yoke by stainless steel plate and stainless steel plate clamped on both sides, fixed with welding The yoke is clamped by stainless steel plate and a stainless steel plate on both sides, fixed by welding, and cooled by water. Induction furnace copper tube: the core of the industrial melting furnace is the induction coil,...
Some customers had confused about which induction furnace is better? Actually, we choose which electric furnace depending on the production capacity and material we use. Here we analyze the condition: Frequency: IGBT belongs to the high-frequency power component and its working frequency is more suitable for > 8KHz; SCR belongs to medium frequency power component and its working frequency is more suitable for < 5KHz; Material Size: IGBT is suitable for material dia
It takes many processes to turn iron ore into steel rebar. After beneficiation, sintering, and blast furnace smelting, molten iron (or scrap steel) is smelted into molten steel by industrial electric furnace, then changed into casting billet by continuous casting machine, and then rolled into corresponding steel by rolling mill (wire rod mill, rebar rolling mill, hot rolling mill, billet mill and TMT rolling mill). Billets from steel mills are only semi-finished products and must be rolled in steel rolling mills before they can become qualified products. The continuous casting billet sent from the steelmaking plant first enters the heating furnace, then enters the finishing mill after repeated rolling by the blooming mill. Steel rolling belongs to metal pressure processing. Steel rolling plates are like noodles. After repeated extrusion and advancement by a rolling pin, the noodles become thinner and thinner. In the hot rolling production line, the rolled billet is heated and softened and then sent to the rolling mill by the roller table. After Sui, it is rolled to the size required by the user. Rolling is a continuous and uninterrupted operation, with a fast running speed of steel strip on roller table, high automation degree of equipment,...
