Medium frequency induction furnace production flexibility

Medium frequency induction furnace production flexibility

Induction quenching furnace in steel industry's role is irreplaceable, medium frequency induction furnace has greater flexibility in produce decorate on, melting operation has greater sensitivity. About power frequency induction furnace for discontinuously task, due to the continuous will add cold start cold start not only add the melting time and power cost, and each one must still use the boot block. And intermediate frequency furnace in for a short time, in the application is not using the boot block with a cold start, intermediate frequency furnace change is very convenient, in the charge of iron liquid and can be completely empty, the material of intermediate frequency furnace can finish within short time change, intermediate frequency furnace to produce organization arrangement. The premise for single small batch produces favor.
 Intermediate frequency furnace, for example, in the iron and steel metallurgy enterprises industry repair workshop, the first bear the required spare parts, spare parts and large iron and steel enterprise cost a yield, and is more sheet small batch production, sort is more, the material requirements often change. The fruit of the intermediate frequency induction furnace in this respect has sensitivity, compensated the power frequency induction furnace and the other the lack of smelting furnace.

The structure of the vacuum induction furnace

 The structure of the vacuum induction furnace

Induction vacuum furnace in the furnace chamber within a particular space using a vacuum system (by the vacuum pump, vacuum measuring equipment, vacuum valves and other components is assembled by meticulously) will be some material discharge furnace chamber, the furnace chamber pressure is less than a standard atmospheric pressure, and complete vacuum furnace cavity space, which is a vacuum furnace.
Vacuum induction furnace usually by host, furnace, electric equipment, sealing furnace shell, vacuum system, power supply system, temperature control system and truck outside the furnace, etc. Sealing furnace shell made of carbon steel or stainless steel welding is removable parts of joint face seal with vacuum sealing material. To avoid heated furnace shell deformation and metamorphism sealing material is heated, usually with water-cooled or air-cooled cooling furnace shell. Chamber of a stove or furnace located sealing furnace shell. According to use the stove, inside the furnace is equipped with different types of heating elements, such as resistor, inductor, electrode and electron gun. Metal smelting in a crucible furnace, vacuum furnace of some manipulator with active casting equipment and loading. Vacuum system is mainly composed of vacuum pump, vacuum valves and vacuum gauge, etc.

The working principle of vacuum induction melting furnace

The working principle of vacuum induction melting furnace

It is well known that vacuum induction melting furnace process, the metal melting, refining and the whole process of alloying was conducted under the vacuum state, thus avoiding the same gas phase interactions and pollution. Second, under the condition of vacuum, carbon has a strong deoxidization ability, the deoxidizing products CO is pumped to the system, overcome the pollution problem of using metal deoxidizer DNA. Vacuum induction melting furnace process can be precise control of chemical composition of alloy, the activity of containing oxygen, nitrogen and strong affinity of element Al, Ti, B, Zr, etc., can be controlled in the range of a few. Of low melting point metals volatile impurities, such as Pb, Bi, Sn, Sb can evaporate, which play an important part to improve the material performance. Strong induction mixing effect, can accelerate the reaction speed, for the uniform temperature of the molten pool, have the effect very much uniform chemical composition, etc.
Vacuum induction melting process has made rapid development is required for the aerospace industry and there is a close relationship between high temperature alloy material, such as aerospace, missile, rocket and atomic energy equipment needed for high temperature alloy. In not by adopting the method of vacuum smelting production of high temperature alloy, the highest working temperature is usually only 750-810 ℃; And by adopting the method of vacuum smelting production of high temperature alloy, the highest working temperature can reach 980-1090 ℃. This is mainly due to the adoption of vacuum induction melting furnace smelting nickel base and iron base, cobalt-based superalloy, O2, N2 and H2, reduces the gap elements can thoroughly remove non-metallic inclusion, as well as the removal of low melting point metal harmful impurities, such as Pb, Bi, Sb, Cu, Sn, Te, etc.
