A single turn helical coil is used to heat the quartz tube and the tube assembly. The tube assembly is held in place inside the quartz tube by a copper fixture and hydrogen is fed into the quartz tube...
Our client had a requirement to anneal large quantities of work-hardened stainless steel crowns. Induction was suggested for its precise, controllable heating. Since oxidation is unacceptable in the finished dental product, induction heating is the appropriate choice for heating in an inert atmosphere.
The crucible is heated using an induction coil with a four turn pancake at the base that extends upward into a three turn helical coil.
Induction annealing heats steel tubes to 2000 ºF (1093 ºC) in an inert atmosphere for very small areas within precise production tolerances. A two-turn concentrator coil is used to heat the stainless steel tube. The annealing process takes place in an inert atmosphere to prevent oxidation.
To heat a steel hydraulic hose fitting in an inert atmosphere to 2200°F within 7 seconds for brazing without any carbon buildup.
To heat a copper tube assembly in an inert atmosphere to 1450°F within 45 seconds for brazing without flux or acid wash clean-up.
To use induction heating to braze a copper tube to a brass fitting using a preform braze wire.
