The structure of the steel shell furnace shell
The furnace shell is made of high-quality thick steel plate and welded by a squirrel-cage frame structure. The window has a detachable cover plate, and the frame bottom plate is made of high-quality thick steel plate. A contour yoke is provided in the furnace shell. The yoke shielding can reduce the magnetic flux leakage to prevent the furnace body from heating, improve the electric energy efficiency, support the induction coil at the same time, improve the strength, and can conveniently disassemble the coil and repair, observe and dissipate the coil when the yoke is not taken away.
The steel shell intermediate frequency melting furnace often adopts the following four configurations :
Each of the four configuration schemes has its own advantages and disadvantages. It is usually necessary to select the specific configuration method according to the casting process requirements of the equipment demand side, the on-site power conditions, the production target and the development scale to meet the requirements of efficient, safe and stable use of the equipment. Easy to flexibly adjust the process or scale expansion.
Scheme a single power supply;
Scheme second single power supply (series resonance) a tow two ways;
Scheme three pairs of power (parallel resonant) dual power supply;
Program four large and small power supply + double power supply switch turned furnace.;
Does the steel shell induction furnace save electricity than the aluminum shell induction furnace?
In theory, it is correct. However, since the silicon steel sheet constituting the yoke generates a large amount of heat, it needs to be cooled by water. Although a part of the magnetic field is concentrated, the loss of the silicon steel sheet is consumed, so the steel shell induction furnace does not save electricity compared to the aluminum shell induction furnace. From the point of view of energy conservation, the outer shell of the aluminum shell induction furnace does not need to be cooled by water, and the outer shell and yoke of the steel shell furnace need to be cooled by a lot of water pipes. The steel shell induction furnace is definitely wasting electric energy than the aluminum shell induction furnace. In practical use, one ton of energy-saving aluminum shell induction furnace melts one ton of steel and uses less than 500 degrees of electricity . One ton of steel shell induction furnace melts one ton of steel and uses more than 600 degrees. Power saving, because the magnetic leakage is less, the steel shell has the shielding effect of the yoke, and the magnetic field is accumulated in the center of the furnace to the greatest extent!
How to save electricity in the steel shell intermediate frequency melting furnace ? ?
1. Considering from the power supply: one is thyristor rectification, inverter. The power factor of the six-pulse rectification is low and the interference is large, and the power consumption is large. It would be better to use twelve veins.
2. Another type of power supply is a series steel shell intermediate frequency melting furnace , which is divided into 6- pulse and 12- pulse rectifiers. Generally, a 1- ton furnace adopts 12- pulse rectification, which has high power factor and saves electricity.
3. From the furnace: aluminum shell and steel shell, aluminum shell without magnetic heat, large heat, power consumption. The steel shell must have magnetic enthalpy, and the magnetic circuit has sequential power saving .
4. Before the molten steel in the furnace is full, the oven must be such that the furnace is in a full state, the compacted material, the greater the output power of the power, the faster the volume reduction, while repeatedly add materials, so they can quickly fall into the molten pool, the material can not be Suspended to prevent the molten steel below from boiling and causing the furnace to wear.
What is the difference between a high frequency melting furnace and a steel shell intermediate frequency melting furnace ?
The high-frequency melting furnace is suitable for melting gold, silver, copper and other alloys. The higher the power, the faster the melting speed, the temperature is up to 1800 °C , the high-frequency melting furnace is economical and practical, the melting is efficient, and the melting is fast . Current frequency is 100 ~ 500 kHz (kiloher), suitable for melting 1-5 KG precious metals, fast, cheap, small size, small footprint .
The steel shell intermediate frequency melting furnace includes 0.25T-10T steel shell intermediate frequency melting furnace , which is widely used in the smelting of non-ferrous metals, mainly used in smelting steel, alloy steel, special steel, cast iron and other ferrous materials and stainless steel, zinc and other non-ferrous materials. . The current frequency is between 500 and 10000 Hz (Hertz), melting 5KG-60T various metals, featuring fast speed and high efficiency .
The main factors leading to steel shell intermediate frequency melting furnace accidents ?
The causes of most steel shell intermediate frequency melting furnace accidents in metallurgical plants are:
1 . The presence of moist materials in the charge causes a steam explosion.
2 . Temperature sampling or lack of operating skills when adding alloys, causing splashes of molten metal.
3 . Injecting large metal materials into the furnace causes the molten iron to splash.
4 . Unreasonable feeding system leads to bridging.
5 . Failure to escape outside the safety line resulted in injury.
6 . Contact with the power conductor, safety interlock control failure or contact with incompletely discharged capacitors, etc., resulting in shock or death.
7 . Lack of proper safety training.
Steel shell intermediate frequency melting furnace yoke structure
A , the yoke is made of WISCO's Q140 with oriented cold-rolled thickness of 0.3mm high-quality silicon steel sheet, and clamped on both sides with stainless steel plate. Optimized by microcomputer design, precision production, the contoured arc surface structure is consistent with the outer diameter of the coil. The yoke (induction coil) covering an area of more than 70%, the yoke fixing method: the yoke close to the induction coil, with high temperature high pressure between the insulating cushion, with 5 out of M24 captive jacking screw yoke On the back of the stainless steel plate.
B. The inside of the yoke stainless steel clamping plate is equipped with a specially designed water-cooled radiator. When the electric furnace is in operation, the yoke temperature is kept at normal temperature to prevent the yoke temperature from rising and deformation, thereby strengthening the support of the induction coil and improving The overall strength of the furnace.
