Indtherm is one of the leading manufacturers of Induction Furnace, based in Kolkata (India).
There is hardly 1.5 to 2.0% loss in induction melting of steel but even it can be also avoided with the help of covering of crucibles. just open it at the time of charging only is the best practise to avoid oxidation & heat losses for Induction melting for steel.
for oil fired furnace it is 4% , n for induction billte heater it is around 1%.
As magnetic field is changed sinusoidally the Foucault currents induced in the metallic body heats the body and melts it. This is the principle of induction furnace
Thyristor is used for Rectifiying and inverting the power supply in induction furnace. The parallel Resonance Coils (Current Control Furnaces) Control the Furance power up to 40% by controlling the firing angle of the rectifier inverter and remaining 60% controlled by inverter thyristor control. In rectifier they are varying the thyristor firing angle from 15 deg to 45 deg. (in sin wave)
Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, where eddy currents are generated within the metal and resistance leads to Joule heating of the metal.induction heater including high frequency induction heating machine and middle frequencey heating machine. Induction heating applications for an induction furnace include induction welding, induction brazing, induction hardening, induction melting, quenching, forging, soldening, induction annealing and other forms of heat treatment. Induction heating is often used to heat graphite crucibles (containing other materials) and is used extensively in the semiconductor industry for the heating of silicon and other semiconductors. Induction heating can produce high power densities which allow short interaction times to reach the required temperature. That translates into lots of energy transferred into a material right now, with a very rapid rise in temperature.
Induction
Yes. It can be
1250V
allu will consume 570 - 600 kwh/ton for meltin in induction furnace in normal working conitions.
You can read how to install an induction furnace on various sites. A better way to get an idea of how to install it is by viewing a Youtube video which details a step by step process of how its installed.
soderberg electrode is silicon carbide to induction furnace
SiO2 refractory
An induction furnace is an electrical furnace in which the heat is applied by induction heating of a conductive medium (usually a metal) in a crucible placed in a water-cooled alternating current solenoid coil.
slag of induction furnace having 49% of feo . is it higher side
It means the Phase anlge is not matching with control board phase angle or more capacitor connected in the furnace line. we have to Remove some tank capacitor.
Read the tag on your furnace for the input/output rating. American Standard and all other manufacturers make more than one size furnace.
simply by measuring the coil voltage, coil current & power factor.
