Method for gas hardening of parts after completion of vacuum carburizing process

摘要

method of toughening gas details after completion of the coal usage in poland in jednokomorowym vacuum vacuum oven with cooling gas wysokociu015bnieniowym [hpgq] is that monitoring the surface temperature of the detail of the load via termoelementu, at 20 - 75 degrees above the transformation temperature martenzytycznej quenched gas inputsuspends the process cooling by the immediate closure of the outlet nozzles and on time from 15 to 75 seconds, depending on the cross-section of the part.
