Abstract
Oil quenching of complex bodies with asymmetric elements is a
fi re hazardous, high-cost and out-of-control process. Joint bar is one of complex bodies with asymmetric confi guration. This type of heat treatment is applicable for it to meet the Technical requirements. Ecologically friendly technique and water regulated cooling device of joint bar have been developed by OJSC «VNIIMT». Due to using water as a coolant polluting emissions into the atmosphere has been completely eliminated, so there is no need of oil purchase, its replacement and disposal. Test-bench experiments at the pilot-production set resulted in obtaining the requirement level of mechanical properties in accordance with the Technical requirements. Joint bar linearity has been provided by water separate supply for each section of the pipeline. The presented
results have given occasion to acquisition of controlled cooling device process conditions. The proposed technique can replace successfully a conventional one – oil quenching.
