Cooling Method of Medium Frequency Induction Furnace

Medium Frequency Induction Furnace,Induction Furnaces


The cooling methods of medium frequency induction furnace are mainly divided into water cooling and air cooling, among which water cooling is the most widely used cooling method. Water cooling can be divided into internal circulation cooling and external circulation cooling. Cooling methods include pool cooling, open cooling tower and closed cooling tower.


Cooling Method of Medium Frequency Induction Furnace

Water Cooling:

Internal circulation cooling:

Use pure water to form a closed cycle inside the induction coil, electrode and other components to take away heat. 

External circulation cooling:

Through spraying, heat exchange and other methods, the internal circulation cooling water is cooled to reduce the water temperature so that it can be continuously recycled. 

Cooling water requirements:

There are requirements for the water quality, pressure and temperature of cooling water. For example, the cooling water system of the induction coil and capacitor usually uses industrial pressure water, the pressure is maintained at 0.15-0.2MPa, the water temperature is maintained between 20-35°C, and the outlet water temperature is lower than 55°C, according to the Hubei Provincial Emergency Management Department. 


Air cooling:

Air cooling method: Use air convection to take away heat through fans and other equipment.

Application scenario: Air cooling is mainly used for some medium frequency furnaces with lower power, or as auxiliary cooling for water cooling system.


Others:

Various components of medium frequency induction furnace, such as main control board, thyristor, reactor, induction coil, water-cooled cable, capacitor, etc., will generate heat during operation and need to be cooled. 

Some medium frequency furnaces use water-cooled cables and form a cooling system together with induction coils. 

Some medium frequency furnace use water pool cooling, and some use open or closed cooling towers. 

Internal circulation cooling and external circulation cooling can effectively prevent medium frequency induction furnace coils and other components from being damaged due to overheating.


In summary, there are various cooling methods for medium frequency induction melting furnaces, but water cooling is the most commonly used, and usually a combination of internal circulation and external circulation is used to ensure the safe and stable operation of the equipment.

VD VOD Refining Furnace: The Working Principle

图片
  VD VOD refining furnace all operated in a vacuum environment to improve the quality of steel. VD furnaces use a five-stage steam jet pump to establish a vacuum environment so that the molten steel can be refined under negative pressure. The refining time is usually about 30 minutes.  VD refining is mainly to remove gases and impurities such as hydrogen, oxygen, and nitrogen in the molten steel to prevent air pollution and avoid steel defects. VD VOD Refining Furnace : The Working Principle The working principle of the VOD furnace is similar to that of the VD furnace, but the specific operation may be different. The VOD refining method is to place the primary molten steel in a closed tank and evacuate it, while blowing argon at the bottom of the ladle for stirring. VD Refining Furnace Vacuum Decarburization, referred to as VD, is a widely used vacuum refining furnace that can effectively reduce the hydrogen and nitrogen content in steel, remove oxygen in steel through carbon-...

Application of Medium Frequency Induction Furnace

图片
  The medium frequency induction furnace is a special smelting equipment suitable for smelting high-quality steel and alloys. It has the advantages of fast melting speed, high production efficiency, strong adaptability, flexible use, good electromagnetic stirring effect, convenient startup operation, and molten steel covered by slag (reducing atmospheric pollution to molten steel). It uses the principle of electromagnetic induction, with fast and uniform heating speed. Its widely used in metal smelting, heat treatment, forging heating and other fields. It is suitable for a variety of metals, including carbon steel, alloy steel, copper and aluminum. It has a wide range of applications, including heat treatment (such as quenching, annealing, tempering) and hot forming (such as forging, hot upsetting). Due to its energy saving, environmental protection and easy operation, the medium frequency induction furnaces has an important position in industrial production. Composition of Medium ...

Working Characteristics of Ladle Refining Furnace

图片
Ladle Refining Furnace ( LRF, LF ) is an important equipment in steel smelting. It is mainly used for secondary refining of molten steel after primary refining in converter or electric furnace to improve the purity of molten steel, adjust the composition and temperature. Its working characteristics are as follows: Features of Ladle Refining Furnace 1. Diversified functions Precise composition control: Through alloy fine-tuning, the composition of molten steel (such as C, Si, Mn, etc.) can be accurately adjusted to meet the requirements of different steel grades. Temperature uniformity: Through arc heating to compensate for temperature drop, ensure uniform temperature of molten steel (usually controlled within ±5℃) to meet continuous casting requirements. Desulfurization & deoxidation: Through the production of reducing slag (such as CaOAl₂O₃-based slag) and argon blowing and stirring, deep desulfurization (can be reduced to below 0.005%) and deoxidation. Inclusion removal: Throu...
