Medium frequency induction heating furnace The medium frequency induction heating furnace consists of medium frequency power supply, medium frequency electric furnace body, furnace front control and other parts. The medium frequency power supply is a thyristor medium frequency power supply that converts three-phase industrial frequency AC into DC through a rectifier circuit, and then outputs single-phase medium frequency AC through an inverter circuit to supply the medium frequency induction furnace. Then, using the principle of electromagnetic induction, the workpiece is placed in an alternating magnetic field to generate eddy currents and generate heat to meet the requirements of melting and smelting. At present: the medium frequency induction heating furnace includes 1 ton medium frequency induction heating furnace, 3 ton medium frequency induction heating furnace, 3 ton medium frequency induction heating furnace, and the maximum tonnage is 40 tons medium frequency induction heating furnace Performance characteristics of medium frequency induction heating furnace: 1. Complete equipment protection The whole machine is equipped with water temperature, water pressure, phase loss, overvoltage, overcurrent, voltage limit/current limit, start-up overcurrent, constant current and buffer start, so that the equipment starts smoothly, the protection is reliable and rapid, and the operation is stable; 2. The layout of...
Induction heating furnace related Induction heating is used to heat large pieces of metal, the purpose of which is to obtain a completely uniform temperature. There, the high power intensity of induction heating is limited by the rate at which heat is conducted from the surface to the center. Surface hardening takes advantage of this “disadvantage”. The application of induction heating is very important. Although the basic principle of various induction heating methods is the same, there are great differences in the application. The figure shows an example of a part suitable for induction hardening. Examples of parts suitable for induction hardening are treated only in the areas of the part that need to be hardened. By using high frequency to obtain high power density, the heat can be quickly concentrated in a local area. Without affecting the rest of the material, only the metallurgical properties of this area are changed, resulting in a thin surface hardened layer on the part supported by a low brittle center. These maintain a certain strength in the center and high wear resistance on the surface, and there is virtually no deformation of the part during the hardening process. For example, the torsional strength...
Curved pipe anti corrosion As a manufacturer specializing in the R&D, design, and production of 3PE anti-corrosion equipment for steel pipes, Luoyang Hongteng Electrical Equipment Co., Ltd., customers should purchase the company’s 3PE anti-corrosion equipment for steel pipes, whether they want to prevent corrosion for straight pipes or curved pipes. However, there is still a big difference in the anti-corrosion operations for straight pipes and curved pipes. For the anti-corrosion of straight pipes, 3PE anti-corrosion structures are often used. The straight pipes have regular shapes, simple operations, and easy mechanized operations. The 3PE anti-corrosion layer has a three-layer anti-corrosion structure, and its anti-corrosion coating is more uniform, the three-layer adhesion is stronger, and the low-density polyethylene and adhesive layers have better isolation effects on various corrosion conditions in the soil environment, and have stronger impact resistance, deformation resistance, and waterproofing ability, which can effectively solve the anti-corrosion problem of straight pipes. spraying in large diameter steel pipe As an essential component in pipeline construction, the curved pipe has an irregular special geometric shape and cannot be batch anti-corrosion on a continuous operation line like the straight pipe anti-corrosion. Traditional curved pipe anti-corrosion technology has the defects of not matching...
Heating furnace sales This article will give you a better understanding of our professionalism Heating furnace sales. The title of this chapter is somewhat inaccurate, because it is the temperature of the charge (workpiece) that needs to be controlled, not the temperature of the furnace. Despite this inaccurate title, it is retained in its current form because it has been widely used. According to the requirements of metallurgists, the goal is to bring the surface of the charge to a given temperature and maintain this temperature until a specified temperature uniformity is achieved in the charge, or to change the temperature of the charge according to a specified heating and cooling cycle. In both cases, the uniformity of the charge temperature is required for all parts of the furnace. The interior of the charge should reach a given temperature without exceeding this temperature. The reason is very simple. For each specific process (rolling, forging, bending, extrusion, annealing, heat treatment) and for each specific material, there is a minimum temperature that must be reached for the process to proceed smoothly. Temperatures that exceed the required value by a large amount are not only a waste of heat, but also often have undesirable consequences, such as excessive oxide scale, decarburization...
induction furnace for heating billets Figure 2.9 shows the principle of an induction furnace for heating billets. An induction coil, to which an alternating current is fed, surrounds the billet to be heated. This induction coil is usually water-cooled and has a refractory lining. In practice, the induction coil is generally much longer than a billet, which is supported on water-cooled slide rails and pushed through a horizontal induction coil. The billet can be pushed into the charging end of the induction coil by a hydraulic or pneumatic push rod. A clamping mechanism or friction mechanism can also be used to allow the billet to be fed continuously. There is little advantage in filling the induction coil with billets in this way. The most expensive and least electrically efficient method of moving billets is to use a stepping mechanism. When the diameter of the steel bar reaches 38 mm or more, the billet can be fed continuously. At the discharge end, a discharge roller is usually installed, which is particularly important for continuous feeding induction heating furnaces to prevent the head of the billet from being gradually cooled. An induction coil is only suitable for workpieces within a certain diameter...
Heating furnace 2025 Until now, the old flame furnace has remained an attractive alternative heating method due to its low capital investment, and its importance is comparable to that of the penetration induction furnace when oil and gas costs are low. Because fuel costs are unstable, accurate cost comparisons can only be made for specific equipment within a specified period, but it is always important to consider other practical aspects besides the capital investment. Induction furnace 1. The time required to heat the billet in an induction furnace is much shorter than the time required to heat it in a flame furnace. Therefore, such a short heating time helps to reduce the production of oxide scale. The typical oxide scale content of flame furnace heating is 3-4%, which can be reduced to 0.5% by electric heating. Oxide scale fragments will cause accelerated wear of forging dies (one company estimates that the life of the die can be increased by 30% due to the minimal oxide scale of induction heating). 2. Since there are no combustion products in the heating zone, oxidation and decarburization of the steel parts are effectively avoided, so clean billets can be obtained by this...
