Medium Frequency Hydraulic Steel shell furnace KGPS-4500KW/6000kg

According to industry habits, the outer casing adopts welded steel structure. In order to avoid short circuit of the circuit, the furnace is equipped with a magnetic circuit. The induction melting furnace of the steel structure with the hydraulic cylinder as the tilting furnace is commonly called steel shell furnace, is composed by

1). Thyristor intermediate frequency converter (power supply cabinet);          2). equipped with hydraulic cylinder and magnetic steel shell body;     3). capacitor bank;      4). water-cooled cable;   5) . hydraulic station 6) furnace lining.

It is used in smelting steel, iron (cast iron), scrap metal, aluminum, aluminum and copper alloys, zinc, lead and other ferrous and non-ferrous metals. The recommended mode of operation is three shifts, but the stove can work normally in one shift if needed. They have high performance, low cost, low pollution, low noise, meet national environmental protection requirements, power control, flexible and convenient, continuous and stable control, uniform temperature, low oxidation loss, uniform metal composition; overall power factor process Maintaining above 0.96, no additional compensation is required. Our steel shell furnace can be melted directly from the cold furnace, the solution can be completely dumped, and the molten material can be easily replaced.

The advantages of steel shell furnaces compared to aluminum shell furnaces:

1. The steel shell furnace body adopts high-performance insulating material with good stability, which is beneficial to prolong the service life of the lining; the furnace is durable, beautiful and not easy to damage.

2, around the coil in the steel shell furnace, covering more than 50% of the yoke made of silicon steel sheet, the structure has a good compression effect, closer to the induction coil, fully utilizing the magnetic field steel of silicon to increase the magnetic permeability, effectively collecting magnetic The polyline enters the molten pool to prevent the furnace body from heating and improve the integrity of the effect system. The magnetic lines generated by the induction coil are shielded and emitted, the magnetic flux leakage is reduced, the thermal efficiency is improved, the output is increased, and the energy saving is about 5%-8%. . High melting efficiency, wide frequency adaptability, always maintaining the best resonance state during the melting process, durable, not easy to damage

3. The steel shell furnace will not interfere with the surrounding electrical equipment, nor will it pollute the grid.

4. The steel shell furnace has a longer service life than the aluminum shell furnace, and its normal service life is 10 years. Aluminum shell furnace is a simple structure, the service life is generally about 5-8 years, there is no magnetizer, furnace lining mechanism, refractory clay layer, its safety performance is poor, generally used for capacity below 2T. For example: a 5T medium frequency furnace, when the furnace is full of molten iron, the overall weight of the equipment reaches 8-10T. If the aluminum shell structure is selected, when the reducer rotates the furnace body to 95 degrees, the whole furnace body will lean forward, and the safety performance is very good. difference. The aluminum shell furnace is suitable for users who change production in a short time, small tonnage. Aluminum is more oxidized at high temperatures, causing metal toughness to fatigue. In the foundry industry, it is often seen that the shell of the aluminum shell furnace used for a year or so is broken, and the steel shell furnace has a much lower leakage current, and the service life of the equipment greatly exceeds that of the aluminum shell furnace.

5, steel shell furnace safety performance is much better than aluminum shell furnace, especially large capacity furnace body, need a strong rigid structure, from the safety point of the tilting furnace, try to use steel shell furnace. When the aluminum shell furnace is smelted due to high temperature and heavy pressure, the aluminum shell is easily deformed and the safety is poor. The steel shell furnace is cast at a fixed point. The hydraulic tilting device can be used to grasp the angle and speed of the dumping. It is safe and reliable. Its good characteristics are selected in steel shell furnaces with tonnage greater than 2T.
