Overview

Melting metals with induction heating is usually accomplished by heating the metal in a crucible made from a non-conductive refractory material. The charge of metal within the crucible is melted down to liquid form.

This process is commonly used to produce high quality steels and nonferrous alloys for casting operations. The liquified metal is poured into a cavity having the desired shape. The metal solidifies with a minimum of shrinkage, after which the mold is removed to reveal a finished, machinable product

Using Induction

Induction heating provides:

• reliable

• repeatable

• non-contact

• energy-efficient

• flameless

heat in a minimal amount of time. Very small areas are heated within precise production tolerances without disturbing individual metallurgical characteristics. Parts are brazed with induction under a controlled atmosphere without flux or any additional cleaning steps.

Both ferrous and non-ferrous alloys can be melted in induction furnaces. The flexibility and cleanliness of induction melting cannot be duplicated by conventional steel mill and foundry methods.

Typical induction furnaces for melting range from 1 to 250kW, depending on the metal and application requirements.
