HEAT TREATMENT

Heat treatment is carried out in an electric bogie hearth furnaces or furnace-shafts which has a liningof filamentous materials. Its possible to carry out heat treatment in an inert atmosphere of nitrogen. Thefurnace temperature regime regulation is controlled by a central computer via thermal sensors withregistration and recording of the process.

Cementation of the surface is provided by controlled carburization in protective atmosphere.
