1. The Concept of Inductotherm Furnace for Sale
An inductotherm furnace for sale is a device that converts three-phase power frequency alternating current into direct current after rectification. And then converts the direct current into the adjustable current to supply the alternating current flowing through the capacitor and induction coil. It generates high-density magnetic lines in the induction coil and cuts the metal material contained in the induction coil, creating a large eddy current in the metal material. This type of eddy current also has some properties of current. Or we can say the free electrons of the metal itself flow in a resistive metal body to generate heat, which is the heat generated by the heating of the induction furnace itself.
2. Heating Capacity of Inductotherm Furnace
The heating capacity of an inductotherm furnace for sale is the magnitude of the heating power, which is directly related to the metal material being heated, heating temperature, heating time, heating efficiency, material specifications, and the heating weight of the metal material. Different heating processes and requirements have differences in heating power and frequency.
3. Heating Conditions of Inductotherm Furnace for Sale
Inductotherm furnace heating generally follows the heating principles of ring effect, Horn effect, skin effect, and proximity effect.
Ring effect: When the current passes through cylindrical, circular or helical cylindrical tubular parts, the large current density distribution is concentrated on the inner side of cylindrical parts, that is, the current density inside the ring is large. This phenomenon is called the ring effect.
Horn effect: Put sharp corners (edge angle) or irregularly shaped parts in a toroidal inductor. If the height of the part is less than the height of the inductor, during induction heating, the sharp corner or edge part of the part will be heated intensely. Due to the strong eddy current, the temperature will rise in a very short time, causing overheating. This phenomenon is called the horn effect.
Skin effect: When current passes through a conductor, the current density along the surface of the conductor increases, and the current density decreases towards the center, which is the skin effect.
Proximity effect: When the current direction of two current-carrying conductors is the same, the intermediate frequency power current flows through the outer side of the two conductors, resulting in a low current density on the adjacent surfaces of the conductors. On the contrary, if the direction of the current is opposite, the current flows from the inside of the two conductors, indicating a high current density on the adjacent surfaces of the conductors. This phenomenon is called the proximity effect of high-frequency current. The higher the frequency, the closer the two conductors are, and the more significant the proximity effect.
