1. Ordinary KGPS SCR parallel 3T intermediate frequency iron melting furnace

The advantages are: it has been the most widely used in the past few decades, low price, easy maintenance, and cheap accessories.

The disadvantage is: high energy consumption, electricity consumption per ton of molten steel is about 750 degrees or more. The power is adjusted by adjusting the DC voltage, the power factor is low ( ≤0.90 ), and there is harmonic interference, which has varying degrees of impact on the operation of the reactive power compensation capacitor in the substation.

The aluminum shell 3T intermediate frequency iron melting furnace body is low in price, easy to maintain, and convenient to observe. The disadvantage is low efficiency and no shielding of electromagnetic radiation.

1. The steel shell furnace body is sturdy and durable, beautiful and generous, especially the large-capacity furnace body, which requires a strong rigid structure. From the safety point of view of the tilting furnace, try to use the steel shell furnace.

2. The steel structure is welded, and there is a leak-proof furnace alarm device, and the sensor is enclosed by a magnetic yoke, covering an area of more than 65% . Because of its low magnetic flux leakage and high efficiency, it saves nearly 5 % of energy consumption compared to aluminum shell furnaces .

3. The existence of the furnace cover reduces the heat loss and improves the safety of the equipment.

4. Long service life, aluminum is oxidized more severely at high temperature, resulting in fatigue of metal toughness. At the foundry site, it is common to see that the shell of the aluminum shell furnace that has been used for about one year is in bad condition, and the steel shell furnace has less magnetic flux leakage, and the service life of the equipment greatly exceeds that of the aluminum shell furnace.

5. The safety performance of the steel shell furnace is much better than that of the aluminum shell furnace. The aluminum shell is easily deformed due to high temperature and heavy pressure during smelting, and the safety is poor. The steel shell furnace uses hydraulic tilting furnace, which is safe and reliable.

Fully enclosed soft water circulation cooling to prevent pipeline blockage caused by debris; avoid scale formation of electrical components, which can greatly reduce the failure rate of the intermediate frequency furnace and extend the service life of the equipment; automatic digital display temperature control, energy saving and environmental protection, easy installation and operation , Simple maintenance;

2. Pool + water pump + cooling tower The water in the pool is pressurized into the equipment through the pump, and the effluent flows back to the pool for recycling. The cooling tower dissipates the heat in the water, and the cooling tower uses strong wind to cool the circulating water, which can effectively increase the heat dissipation and reduce the user's pool;

3. Pool + water pump The water in the pool is pressurized into the equipment through the pump, and the effluent flows back to the pond for recycling. Naturally dissipate heat through flowing water;

Different power and use the device, the required cooling water is not the same; our technicians will be needed equipment . You match data pool size or capacity of the cooling tower.
