Technological Processes of Roll ManufactureProduct transfer

design – roll billet -smelting (EF+LF orEF) casting (rolling) electrode – electro-slag refining (ESR)- high-temperature diffusion annealing forging – spheroidizing+diffusion hydrogen annealing rough processing -Inspec-tion (UT flaw detection) rough turning UT flaw-detection quenching and tempering treatment – ,inspection semi-finishprocessing flaw detection – , quenching + tempering on rollneck inspection – grinding before quenching (UT flaw-detec-tion) quenching + tempering on roll body inspection . -finish processing rough grinding ,semi-finish grinding – ,(extra) finish grinding inspection (UT flaw-detection) anti-rusting – packaging delivery , storing inspection – opera-tion and maintenance exchange in site improving design.
