How many reasonable vacuum induction furnace quotation?

Vacuum induction furnace belongs to a kind of vacuum furnace, mainly by the effect of electromagnetic induction, creates an electric current in metal furnace charge itself, and then rely on the resistance of the metal charge itself, according to the joule - lenz's law, the electric energy into heat energy, thus melting metal. Because the vacuum induction furnace without pollution, environmental benefits is better, therefore, it is very popular with the consumers in the market. When consumer is buying the vacuum induction furnace, besides will focus on the quality of the products, for the product price is also very the attention of the market price of vacuum induction furnace above? Vacuum induction furnace reasonable price?
Now, vacuum induction furnace above the market price is very chaotic, there are some bad suppliers use inferior materials product, thereby reducing the product cost, thereby lowering the price of vacuum induction furnace, as a result, some consumers will choose cheaper products, thus caused the chaos on the market of vacuum induction furnace, the product quality is uneven, the price of the good and bad are intermingled. The market the vacuum induction furnace above the price is reasonable? How much is the vacuum induction furnace?
Actually, because the quality of the vacuum induction furnace and cost issues, in general, the vacuum induction furnace quotation above market should in 4-100000 yuan or so, but there is some price is thousands or even hundreds of, these products are advised consumers to choose carefully, because the quality of these products may have some defects, and, of course, can also be second-hand products, so consumers need to consider carefully.

Several advantages of medium frequency furnace steelmaking

1 simple, intermediate frequency furnace equipment. Compared with electric arc furnace, intermediate frequency furnace itself does not need large furnace equipment, don't need a large furnace equipment (such as hydraulic pressure, rotating mechanism, etc.), also don't require a lot of water cooling system, so its monomer equipment investment is relatively low, the equipment is simple and easy to master.
2, only has the function of the steel because of intermediate frequency furnace, no oxygen blowing in steelmaking process, so don't oxygen generator and other large equipment, it can also save money.
3, due to the small size, medium frequency furnace height is low, so the factory also was much lower than other steelmaking workshop, therefore, its cost in the factory building construction is also less than other types of steelmaking plant.
4, small and intermediate frequency furnace capacity, production arrangement is more flexible, especially suitable for small single piece casting production.
5, in addition, power frequency furnace and its related technology level is low, short-term easy to grasp.
6, the most low-end products in the market demand is not high, intermediate frequency furnace comprehensive cost is lower than other steelmaking process.

Nine items that should pay attention to maintenance of vacuum induction furnace

Yet how many people know that vacuum induction furnace correct maintenance method? The following is to detailed introduction:
1, after the work, needs to keep in vacuum induction furnace 133 pa vacuum.
2, there is dust or not clean inside the equipment, application of alcohol or gasoline wet silk cloth to wipe clean and dry.
3, sealing parts, parts disassembling, application of aviation gasoline or alcohol to clean, dry vacuum grease on besmear after reload.
4, equipment outside surface should often wipe, clean clean. The same is true of the use of vacuum tempering furnace.
5, electric control system of electric connection should be kept clean, fastening, in each furnace should check before fastening electric connection.
6, should check the insulation resistance of the furnace, when insulation resistance less than 1000 euro, should carefully check the electric heating element, electrode and isolation layer thermal resistance, etc., and troubleshoot rear can furnace.
7, mechanical transmission parts in accordance with the requirements of general equipment lubricating oil or oil change on a regular basis.
8, vacuum unit, valves, instruments and meters and other accessories, all press products are vacuum furnace maintenance with the specifications.
9, vacuum furnace maintenance should be a power outage maintenance, in the case of charged maintenance, must ensure that the operating personnel, maintenance personnel and equipment is absolutely safe.

Aluminium scrap melting equipment - induction melting furnace

Common induction melting furnace, the core and has two kinds of core, the advantage of this furnace is:
(1) breathe in less and less oxidation burning loss, general metal aluminum burning only around 0.5%. Raw material broken hours is not 1%, up to 5% for aluminium scrap.
With a strong magnetic field lines (2) when the melt mixing, uniform composition, melting fast, very favorable for broken material.
(3) the unit power consumption is little, high thermal efficiency. In general, power consumption is 380 ~ 450 KWH/tons, thermal efficiency can reach 70%. Resistance furnace is corresponding to 430 ~ 600 KWH/t and 50%.
(4) covers an area of less, good operating environment
Defect is melting channel type induction furnace to replace the aluminum melting trench must be clear, when the species difficult. Followed by melting trench polluted by molten aluminum washout flake refractory in the melt.

Induction melting inject new vitality for casting production

Medium frequency induction furnace is the main equipment in the foundry, stability, reliability and security of its work is flow process of casting production line ensure normal and stable work. At present, the induction melting furnace has been developed rapidly, has gradually replaced the cupola.
Induction furnace except to smelting in the atmosphere, can also in a vacuum and argon and helium protection atmosphere such as smelting, to meet the requirements of special quality. Compared with other melting furnace, in addition to the melting principle, have the following features:
(1) using electromagnetic induction heat the material directly, high thermal efficiency.
(2) due to the melting is not used in the air, burning less elements, less impurities mixed with.
(3) the operation is simple, composition adjustment, easy to add trace elements and temperature control.
(4) around the furnace heat and less smoke generates low, improve the working environment, good for the environment protection.
(5) cover an area of an area small.
(6) current density is high, suitable for high temperature melting.
(7) easy to realize automatic control, especially can use computer to process control.
(8) frequency magnetic field of molten metal has magnetic stirring effect, beneficial ingredients evenly, and dross, uniform composition and temperature of liquid metal.
The application of the induction heating technology in China, originated in the 1950 s, the technique of inductive heating almost entirely from the former Soviet union and the Czech republic and other countries, is mainly used in machine tools, textile machinery, automobile, tractor and other manufacturing industries. Induction heating power supply amount applied to industrial production is in the 1980 s.
