Izinto ezithinta isikhathi sokubamba se-workpiece ku- isithando somlilo sikagesi sokuhlola

1. Ukushisa kokushisa

Ngaphansi kwezimo ezijwayelekile, idatha ye-empirical ivamise ukusetshenziselwa ukubala ezithandweni zokuhlola zikagesi. Isibonelo, i-carbon steel ivame ukubalwa ku-1min/1mm, kuyilapho insimbi ye-alloy ingu-1.3 kuya ku-1.8 izikhathi ze-carbon steel. Isizathu siwukuthi insimbi ye-alloy inokuqukethwe okuphezulu kwezakhi ze-alloying. Kodwa ekushiseni okuphezulu (1000 ℃), uma ukushuba okusebenzayo kukhulu, umkhawulo ophansi wale coefficient usetshenziswa, futhi umkhawulo ongaphezulu wokushuba okusebenzayo mncane.

2. Umehluko emabangeni ensimbi

Ngensimbi ye-carbon steel nensimbi ephansi ye-alloy, isikhathi esidingekayo sokuqedwa kwe-carbides kanye ne-homogenization ye-austenite sifushane kakhulu, ngakho-ke ngokwesimo, ukucisha ukugcinwa kokushisa “zero” kungasetshenziswa, okunganciphisa umjikelezo wenqubo futhi kunciphise imifantu yokucisha. Ngensimbi ye-alloy ephezulu, ukushisa okucishayo kanye nesikhathi sokubamba kufanele kunwetshwe ngokufanelekile ukuze kuqinisekiswe ukuqedwa kanye nokuqinisekiswa kwe-carbides. Ingalinganiselwa ku-0.5 kuya ku-0.8min ngemilimitha ngayinye ngesikhathi sokubamba. Lapho umkhawulo ongaphezulu wokushisa okucisha ungu-0.5min, izinga lokushisa lokucisha lincike kokuthi Thatha i-0.8min emkhawulweni ophansi.
