Steel melting furnace is an induction furnace using steel 200 ~ 2500Hz frequency power supply for induction heating, power 200kw-20000 KW, according to the tonnage divided into: small, medium, large steel furnace.
The steel furnace is mainly used for the induction furnace which is also used for casting, induction furnace steel making and melting steel.
The whole set of steel furnaces consumes about 550 ± 5% kW.h/t of water per ton of steel. The equipment includes intermediate frequency power cabinet, compensation capacitor, furnace body (two) and water-cooled cable, and tilting mechanism . The furnace body is composed of a furnace shell, an induction coil, a furnace lining, a tilting furnace mechanism , and the like. The furnace shell is made of a non-magnetic material, and the induction coil is a spiral cylinder made of a rectangular hollow tube, and the cooling water is passed through the tube during smelting. The coil leads out the copper row and communicates with the water-cooled cable. The furnace lining is close to the induction coil and is sintered by quartz sand. The tilting of the furnace body is directly rotated by the tilting mechanism to pour out the molten iron .

What are the advantages of using steel furnace steelmaking and induction furnace steelmaking ?
1. The electricity consumption of steel smelting tons under normal working conditions is 550-600KW.h ;
2 , the power factor is maintained above 0.96 , no additional compensation device is required;
3. Effectively control high harmonics, do not interfere with surrounding electrical equipment, and do not pollute the power grid;
4 , the frequency adapts to a wide range, and always maintains the best resonance state during the melting process;
5 , zero voltage scanning soft start mode, can be started or stopped at any time in any state, no impact on the power supply;
6 , rapid smelting, low production costs; low pollution, in line with national environmental requirements;
7. It can be directly melted from the cold furnace, and the solution can be completely emptied. It is convenient to replace the melt material;
8. Power adjustment is flexible and convenient, and can be continuously and smoothly adjusted; temperature is uniform and easy to control, oxidation loss is small, and metal composition is uniform;
9. The furnace shell adopts steel structure or cast aluminum alloy, and the floor space is small; the furnace body is easy to turn over and tilt, and manual, electric and hydraulic tilting furnace modes are available;
10 , leaking furnace alarm device, timely and effective protection of personal and equipment safety;
11. The furnace lining and ejection mechanism makes it quick and efficient to replace the furnace lining and improve production efficiency;
12 , wide frequency adaptation range, rapid melting, low production cost, uniform temperature and easy to control;
13 、The furnace body is easy to turn over and the metal composition is even;
14 , small footprint, effective management of higher harmonics.
What is the power consumption of induction furnace steelmaking ?
The power consumption of induction furnace steelmaking is related to many factors, such as the size of the steel furnace , the quality of the scrap, and the skill and laziness of the furnace. Generally speaking, the power consumption is between 550 and 750 degrees, the power consumption of the large tonnage furnace is lower, and the small tonnage is higher.
What are the characteristics of induction furnace steelmaking ?
Induction furnace steelmaking is not called steelmaking. It is to melt steel. The impurities in the steel cannot be removed. This is a disadvantage. The advantage is that some elements in the original steel are not lost, which can reduce the amount of precious elements added and reduce costs.
Steelmaking is the process of getting the pig iron into a steelmaking furnace and melting it according to a certain process. According to the survey online, steel products include steel ingots, continuous casting billets and direct casting into various steel castings. Generally speaking, steel generally refers to steel that is rolled into various steel materials. Steel is a ferrous metal but steel is not exactly equal to ferrous.
