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.

The preparation and production of induction melting furnace before use operation procedures

Preparation of the induction melting furnace before use
1. Check each distributor is normal.
2. Check the water, water pressure and flow rate is in line with the requirements.
3. Check the vacuum pump and vacuum system is normal.
4. Check the control cabinet and temperature measuring meter and the indicator light is normal.
5. The processed workpiece cleaned thoroughly with alcohol or gasoline
6. Artifacts in furnace, tooling, material basket, etc shall be clean and dry.
7. Vacuum cleaning furnace scale and sundry.
8. Use silk or wool fabric dipped in alcohol or gasoline wipe the oven door and furnace cover seal.
9. The workpiece is put should smooth and may not be in the running and scattered and crooked blowing process.
Induction melting furnace production operation procedures
1. The starting power supply, set the switch control cabinet in automatic control location.
2. Input the parameters of the process planning into the computer.
3. The workpiece with charging car smoothly away in furnace.
4. Close the oven door and lock (cover), to ensure the seal.
5. According to the technological requirements to choose good cooling medium and cooling method and pressure.
6. Press the cycle start button, equipment execution procedures: vacuum heating _ _ cooling automatically.
7. Check the equipment each system operation is normal, if there is any abnormal timely report the captain.
8. Before, we should restore the normal pressure in the furnace, the light is normal after open the oven door (cover).
9. When discharging, carefully operation, workpiece and tooling shall glory hole collision.

Several advantages of medium frequency furnace

Medium frequency furnace has the following advantages:
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.

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.
