Edwin Fitch Northrup built the first prototype of a vacuum induction furnace in the United States of America in 1920. [citation needed] Medium frequency furnaces were seen soon afterwards in England and Sweden in 1927. [1] The process was initially developed to refine certain special metals such as cobalt and nickel. As these metals and alloys ...

Furnace anneals are performed by equipment especially built to heat semiconductor wafers. Furnaces are capable of processing many wafers at a time, but each process can last between several hours and a day. Increasingly, furnace anneals are being supplanted by Rapid Thermal Anneal (RTA) or Rapid Thermal Processing (RTP). This is due to the ...
Kaiser Steel was a steel company and integrated steel mill near Fontana, California.Industrialist Henry J. Kaiser founded the company on December 1, 1941, and workers fired up the plant's first blast furnace, named "Big Bess" after Kaiser's wife, on December 30, 1942.
the energies of a generation, for it required all the new machinery to be created—capital, banks, mines, furnaces, shops, power-houses, technical knowledge, mechanical population, together with a steady remodelling of social and political habits, ideas, and institutions to fit the new scale and suit the new conditions.
