CrWMn ishyushye izengurutswe ibyuma

CrWMn ipfa isahani ni ibikoresho byuma byuma, amavuta azimya deformasiyo ikonje ikonje ipfa ibyuma. Kwambara ibyuma, kubera guhuza igice kinini cya 1.20% ~ 1.60% bya tungsten, bikora karbide kuburyo nyuma yo kuzimya nubushyuhe buke kugira ⼀ gukomera no abrasion resistance. ifite inenge nko guturika byoroshye no gusya byoroshye bitewe no gutandukanya karbide.Kuzimya bikunda ibyuma bya karubone, kandi urwego rwo gusaba rukagabanuka. Kurwanya gukomera no gukuramo ibyuma kimwe no gukomera kwicyuma cya chromium na chromium silicon ibyuma nyuma kuzimya nibyiza, kandi gukomera nibyiza.
CrWMn ikoreshwa cyane mubyuma bya karubone ibyuma ntibishobora kuba byujuje ibisabwa mugice kinini cyambukiranya, imiterere igoye yibice bipfa, bisaba kuzimya bike.
1) Ubu bwoko bwibyuma bikoreshwa cyane mugutunganya ibyuma byoroheje, ibyuma bidafite fer, ibikoresho byibanze byumutwaro woroheje hamwe nuburyo bugoye bwo gutera kashe bipfa gupfa, cyane cyane mubice byamasaha, ibikoresho, ibikinisho ninganda zibicuruzwa, nibindi. Ingaruka za uruzitiro rwicyuma cya austenite, urupapuro rwicyuma cya silicon nicyuma gikomeye cyicyuma ntabwo ari cyiza.

2) ubunini bwibyuma burashobora gukoreshwa mugukora ibikoresho <1 mm yo gupfunyika bipfuye bigoye gukubitwa, gupfa gupfa, gushiraho, hamwe nimbaraga ⼀ imirongo ishushanya yimbitse ipfa. Umusaruro wa punch watanze ubukana bwa 58 kugeza kuri 62 HRC, naho umusaruro wububiko bwerekana ko gukomera 60 ~ 64 HRC.

3) Ikoreshwa mugushyiramo punch ipfa hamwe no kwihanganira kwambara cyane hamwe nuburyo bugoye mukunama bipfa. Gukomera kwa punch bipfa gusabwa kuba 58 ~ 62HRC na 60-64hrc birasabwa kuba 60-64hrc mugihe utumye punch ipfa

4.

5) Kubikonje bikonje bipfa kubice byumuringa naho gukuramo imbeho bipfa gupfa byuma, ibyuma bisabwa ni 62-64hrc.

6) Nyuma yo guhimbwa, irashobora gukoreshwa mugukora imashini nini zikoreshwa mumashini yumuvuduko urenga 1mm, mubisanzwe byongera ubukana bwibyuma kugeza kuri 50-55hrc. Nyamara, inenge zigaragara nkimiterere ya karbide yubatswe cyangwa chromatografiya yamazi igomba kugabanuka cyangwa kwirindwa
