Induction Heating and Heat Treatment
Special Applications of Induction Heating
The historical use of induction heating relating to glass melting gives some insight into its use in today's glass manufacturing industry. A patent search on induction heating provides historical information about how induction heating was used in the glass melting industry, from both a direct fired or a susceptor/container approach. This article provides review of historical patents, following an introduction to conductivity in glass and electrical heating. The purpose is to show that induction heating has been and is being used in the glass melting industry.
Induction heating for glass melting is an alternative to resistance heating element furnaces. This article provides information on the basics of glass fabrication process. It focuses on crucible melt furnace for small-scale glass melting and the induction melting process. It also describes induction glass forming (forming from the melt) and glass forming by induction heating (post-melt). The article compares the benefits of using induction heating and refractory-lined resistance heating.
