The process was invented in Hanau, Germany in 1917. Heraeus Vacuumschmelze and Dr. Wilhelm Rohnapplied for a patent on vacuum melting on 12 January 1918 and were granted a German patent DE 345161. E.F. Northrup built the first prototype of a vacuum induction furnace in the United States of America in 1920. Medium frequency furnaces were seen soon afterwards in England and Sweden in 1927. The process was initially developed to refine certain special metals such as cobalt and nickel. As
An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. Induction furnace capacities range from less than one kilogram to one hundred tonnes, and are used to melt iron and steel, copper, aluminum, and precious metals.. The advantage of the induction furnace is a clean, energy-efficient and well-controllable melting process compared to most
Jul 23, 2019· Vacuum furnace Last updated July 23, 2019. A vacuum furnace is a type of furnace in which the product in the furnace is surrounded by a vacuum during processing. The absence of air or other gases prevents oxidation, heat loss from the product through convection, and removes a source of contamination.This enables the furnace to heat materials (typically metals and ceramics) to
Nov 25, 2019· Vacuum induction melting Last updated November 25, 2019. Vacuum induction melting (VIM) utilizes electric currents to melt metal within a vacuum.The first prototype was developed in 1920. [1] Induction heating induces eddy currents within conductors.

Induction Vacuum Melting. Because induction heating is accomplished using a magnetic field, the work piece (or load) can be physically isolated from the induction coil by refractory or some other non-conducting medium. The magnetic field will pass through this material to induce a voltage in the load contained within.
