Ukwelashwa kwendawo okunembayo kwepayipi lensimbi kuwukushintsha ukunemba kokwelashwa kokushisa kwethishu yensimbi ukuze kuguqulwe indawo eyodwa.

Ukuqina kwesakhiwo sobuso beshumi nanye kuyashintsha, ngaphandle kokushintsha ukwakheka kwamakhemikhali okwelashwa kokushisa okungaphezulu. Ingasetshenziswa i-high-frequency, i-intermediate frequency noma i-frequency currents induction induction heat noma izindlela zokushisa ilangabi. Isici sabo esivamile ukuzama ukunemba steel surface is ukushisisa ngokushesha ukuze izinga lokushisa quenching, futhi lapho ukushisa ingakafiki ezingxenyeni zenhliziyo unit, ke ngokushesha selehlile, ukuze high surface ubulukhuni, ukuqina kanye nenhliziyo Ministry namanje okusezingeni eliphezulu.

Izinguquko ekwelapheni ukushisa kwamakhemikhali ukwakheka kwamakhemikhali nokuhleleka kwensimbi okunembe nanye. Ukwelashwa ngamakhemikhali ngokuhambisana nokunemba amashubhu ensimbi angena ebusweni bezakhi ezihlukene angahlukaniswa abe yi-carburizing, i-nitriding, i-carbonitriding, i-alloying nezinye izindlela. Thuthukisa futhi uthuthukise ukumelana kwayo nokunemba kokugqoka kwensimbi, ukumelana nokugqwala, ukumelana nokukhathala kusebenza kakhulu. Ekuthuthukisweni okusheshayo kwamanje kokwelashwa ngamakhemikhali, ukusetshenziswa kobuchwepheshe obuningi obusha.

Ebunjiniyela bemishini, izingxenye eziningi zomshini, njenge-crankshaft yenjini evuthayo yangaphakathi, amagiya, i-cam shaft kanye nesinciphisi segiya kubalulekile, akudingi nje ukuthi ingxenye eyinhloko inokuqina okwanele, i-ductility namandla aguquguqukayo, futhi idinga ukushuba okuthile. kobuso obungaphakathi bobunzima obuphezulu, ukumelana nokugqoka okuphezulu namandla aphezulu okukhathala. Ukwelashwa kokushisa okuhlukahlukene okungenhla kunzima ukwanelisa ngesikhathi esisodwa izimfuneko zokusebenza ezingenhla, kuyilapho ukusetshenziswa kokwelapha ukushisa okungaphezulu kuyindlela ephumelela kakhulu yokufeza lezi zidingo zokusebenza.
