How to solve the decarburization phenomenon of induction heating furnace heating metal?

The carbon in the lower layer of the metal workpiece heated by the induction heating furnace is oxidized, so that the carbon content on the surface of the workpiece is reduced, and the depth of the decarburized layer is related to the composition of the steel, the composition of the furnace gas, the temperature and the holding time at this temperature. related. If an oxidizing atmosphere is used to heat high carbon steel and steel with a high silicon content, it will be easy to decarburize, and the effect of decarburization is to reduce the strength and fatigue of the workpiece.
