Important aspects of operation. As liquid steel is excited by current opposite to current flowing in induction coil, it is agitated to raise its surface in the center. Surface of liquid steel is risen higher as frequency becomes lower, i.e. agitation of the liquid steel occurs stronger in low-frequency furnace than in high-frequency furnace.

Dura-Line® induction melting furnaces with an optional double-trunnion, hydraulic tilt design offers the precision pouring control you need if your induction melting and casting operation requires a precise pour into a stationary opening. This design features two separate pivot axes for a smooth and controlled pouring action.

Induction heating is a popular way of melting metals in a furnace. It relies on induced voltage to transfer energy from the power source to the metal. Current flows through the coil and creates a magnetic field. This induces voltage, resulting in an electric current that heats up the metal and melts it.

It is one of the alternative charge materials to scrap in induction furnaces. National Metallurgical Laboratory has made an attempt to melt sponge iron in induction furnaces and optimize its melting behavour. It is possible to use continuous charging arrangements for melting of sponge iron in induction furnace. Item Type:

furnace to the pouring location (Fig. 1). Fig. 1. Overview of cast iron melting and pouring processes. As a matter of fact, cast iron materials are melted chiefly in cupola or induction-type furnaces today while rotary furnaces are rarely used in this context any more. In isolated cases, such as the grey iron foundry at the

hung from the top of the furnace to the bottom and be contoured to fit against the furnace walls. The length required should equal the height of the furnace plus 5". This will allow for overlap onto the top of the furnace. The overlap cloth can be slit every 6" to allow it to contour the furnace properly.

Download reference work entry PDF. Induction furnace melting is a process of melting metal by using electromagnetic induction to produce eddy current heating in metal materials in induction furnace, also called induction melting.
