Conclusions
-
1.
The design of retorts for chemicothermal treatment must take into account the effect of thermal deformation at high temperatures.
-
2.
Retorts exposed to oxidizing and carburizing atmospheres must have multilayer weld seams — an inner seam consitituting not over 50% of the deposit and a cover weld that is resistant to oxidation and carburizing.
