Application: It can melt all kind of steel for casting mill balls, rebar, ingot and other casting product.
Melting material: carbon steel, stainless steel, high chrome steel , high manganese steel, wild steel ect.
Melting rate:at least 2 tons per hour and temperatures of 1650°C being achieved.
Major Unite
1) steel shell furnace body
2) Hydraulic station and tilting control device
Steel Furnace Features
- Open furnace structure. The basic structure: with unique shock absorber and solid magnetic yoke, two cylinder with thick wall seamless rectangular steel tube is welded into one structure, being safer, firm, durable, high efficient. The upper end of the induction furnace can be disassembled to facilitate the replacement of the coil.
- Hydraulic tilting. Furnace can rotate around the pouring spout, and tilting with proportional control, through controlling buttons of hydraulic station and the handle of tilting control device . Its tilting angle is vertically at 95 degrees and it can stay in any position in the process of rotating, as well as to change titling speed to more quicker or more slowly. It uses the manual valve operation and double machine double pump, with remote manual control system. Some other company only have single pump control.
- Energy saving. The sensor is enclosed with a magnetic yoke, covering an area is over 65%, so the leakage is small and achieve the maximum electrical efficiency. Compared with aluminum shell furnaces, steel shell furnace can save nearly 5% power consumption.
- Furnace leakage alarm. It is equipped with an alarm device for preventing furnace from leakage, which can achieve safe production. It is a special dual leak-proof furnace alarm, when the lining getting thinner to a certain degree, a warning light will be given to alert the user that the lining needed to be replaced.
- Anti-fall protection device. During the process of tilting furnace, the anti-falling protective hood will be automatically raised to form a protective barrier to prevent the personnel from falling.
- Furnace cover & Dust collector. Furnace's cover improve heating efficiency. Dust collector can absorb dust and exhaust gas generated during melting process through air. When working with dust removal system, they can reduce the exhausted gas emission, to meet the environmental requirements.
Common Questions & Solution
1 ) How is the temperature of the furnace measured / calculated?
There are two ways to measure it.
One is artificial way. You can buy a temperature probe to measure the temperature by yourself.
Another is automactical way. Automatic Thermostatic Function is available.
You can set up temperature needed in advanced by controlling the temperature button.
2 ) Is there a measurement to determine when the furnace liner needs to be replaced?
Leakage detected system is available. which has the following two advantages:
a. In case the molten iron leaked from furnace and touch the induction coil, workers will be protect from electric shock even when they are holding a metal rod to touch the molten metal for slag removal or temperature measurement. Besides, there is no induction electricity in the melting metal during regular working.
b. Earthing and leakage condition can still be detected, though the power supply has stopped working.
3 ) Compared with gas /oil /coal fired furnace, what are your advantages?
a. High productivity. As heating fast, the material utilization of induction furnace up to 95-99%. Its oxidation loss is less than0.5%, while gas furnace loss 2%, and coal-fired furnace loss 3%. It can reduce 1.5% slag.
b. Reduce the cost of production. As uniform heating, induction furnace extends the using life of casting mould(10%-15%)
.
c. Energy saving. induction furnace use electricity as fuel, it can save 31.5% ~ 54.3% power than oil-fired furnace, 5% to 40% than gas furnaces.
d. Environmental-friendly. Workers have better working environment, and it improve company's image. Being no pollution, low energy , company can reach the targets environmental protection departments and establish a future with the forging industry trends.
