Isiphumo sesicelo se-polymer quenching medium cooling in izixhobo zokucima

Isiphumo sokusetyenziswa kwezixhobo zokucima Uninzi lwamacandelo acinyiweyo aphakathi kwekhabhoni yentsimbi kunye nentsimbi yesakhiwo se-alloy ephantsi kunye nephakathi, kunye nokusetyenziswa kwe-polymer quenching medium kuzuze iziphumo ezilungileyo. Ngokomzekelo, kwimiqulu edibeneyo eyenziwe nge-48CrMo yensimbi, ubunzima be-roll tooth surface kufuneka bube ngu-≥58HRC, kwaye ubunzulu bobunzima kufuneka bube ≥1mm. Ngaphambili, xa amanzi ayesetyenziswa njengendawo yokupholisa yokucima, ingxaki yokucima ukuqhekeka kwenzeka. Ukusetyenziswa kwe-JY8-20 i-polymer quenching medium cooling for ultra-frequency and medium-frequency quenching of corrugated rolls inokusombulula ngcono ingxaki yokucima iintanda. Idayamitha yangaphandle yenxalenye ecinyiweyo yomqulu othile wamalahle yi-360.96mm. Emva kokucinywa kwe-induction nge-JY8-20 i-polymer quenching medium, ubunzima bomhlaba yi-58-62HRC, kwaye ubunzulu bomaleko obunzima yi-3mm. Zingaphezulu kwama-5,000 iziqwenga zemiqulu eyahlukahlukeneyo eyenziwe ngamatye yalungiswa ngokuqiniswa kwe-induction ngaphandle kokuqhekeka.
