Ikhwalithi ephezulu ye-tungsten carbide ebanda ekhanda ifektri yokufa

I-cold heading die iwukufa okugxivizwayo okufakwe emshinini wokunyathelisa ukuze upuntshwe, ugobe, welule, njll.

Ikhanda elibandayo lingaphansi komthwalo onzima wokunyathela futhi indawo yayo yokufa eyi-concave ingaphansi kwengcindezi ephezulu yokucindezela.Impahla yokufa iyadingeka ukuze ibe namandla aphezulu, ukuqina nokumelana nokugqoka.Ngemva ukwelashwa ukushisa, ebusweni yethutungsten carbide ikhanda elibandayo diekufanele ibe nobulukhuni obuphezulu futhi inhliziyo ibe nokuqina okuhle, ukuze ubuso bube nokucindezeleka okuthile okucindezelayo okungasusa ukucindezeleka okubangelwa inqubo yesihloko esibandayo.Kungenza ukufa kuhlale isikhathi eside.

Ukuze kwandiswe ukusebenza kwemikhiqizo yesihloko esibandayo se-tungsten carbide, yonke yethucarbide ikhanda elibandayo dieizikhala ziyacishwa futhi zithukutheliswe ngemuva kwenqubo yokucwilisa.Inqubo yokucisha neyokushisa ukushisa izikhala zengxubevange e-sintered esithandweni sokucisha igesi esinengcindezi ephezulu ibe ngaphezu kwama-degree angu-1300 bese uzipholisa ngokushesha nangokucijile bese uzishisisa futhi ukuze zithuthe.Kule nqubo, njengoba izinga lokushisa likhuphuka, ukuncibilika kwe-tungsten carbide ku-cobalt kuyanda, futhi izinga lokushisa liphola kakhulu ukuze i-tungsten carbide ehlakazwe esigabeni se-cobalt ingaphumi ngesikhathi, futhi okunye noma konke kugcinwa.Khona-ke uthukuthele ukuqeda ubulukhuni bangaphakathi obucishayo.Ngokulawula ukubola nokusabalalisa kwesisombululo esiqinile esigcwele, ukwakheka kwe-metallurgical kanye nokuhlelwa kwe-alloy kuyashintshwa, futhi ukusebenza kuyathuthukiswa.
