Iyo assy idakora ikonje, ibice byera akenshi biba hejuru kandi ibice bito.
Imiterere yumunwa wera irakomeye kandi yoroheje, hamwe nimikorere idahwitse kandi byoroshye kuyikuramo.
Kubwibyo, annealing (cyangwa ibisanzwe) igomba gukoreshwa kugirango ikureho umunwa wera.Igikorwa cya annealing ni: gushyushya 550-950 ℃ kumasaha 2-5, hanyuma gukonjesha itanura kugeza 500-550 ℃ hanyuma gukonjesha ikirere.Mugihe cyubushyuhe bwo hejuru bwo gufata, cimentite yubushyuhe bwo hejuru hamwe na cementite ya eutectic yangirika muri grafite na A, naho cimentite ya kabiri na eutectoid cementite nayo yaraboze mugihe cyakonje cyakurikiyeho, bivamo inzira yo gushushanya.Bitewe no kubora kwa simaite, ubukana buragabanuka, bityo bikazamura imashini.
Ubusanzwe ibyuma byangirika
Intego yicyuma gisanzwe ni ukubona matrix ya pearlite, gutunganya ingano nuburyo bumwe, kugirango tunonosore imiterere yubukorikori bwa Dandong.Rimwe na rimwe, ubusanzwe nabwo ni ugutegura ibyuma byuma byuzura hejuru yimiterere, mubisanzwe bigabanijwemo ubushyuhe bwo hejuru busanzwe hamwe nubushyuhe buke busanzwe.Ubushyuhe bwo hejuru busanzwe ubushuhe mubusanzwe ntiburenga 950 ~ 980 and, kandi ubushyuhe buke busanzwe ubushyuhe burashyuha mubushuhe buringaniye bwa 820 ~ 860 ℃.Nyuma yubusanzwe, abantu bane basabwa guhangana nacyo kugirango bakureho imihangayiko yimbere iterwa mugihe gisanzwe.
Ubuso bukomeye
Kugirango utezimbere ubukana bwubuso, wambare imbaraga hamwe numunaniro winteko zimwe ziyobora ibiziga, kuzimya hejuru birashobora gukoreshwa.Byombi byuma byumukara hamwe nicyuma cyuma gishobora gukomera.Mubisanzwe, hejuru (hagati) inshuro nyinshi induction gushyushya hejuru no kuzimya amashanyarazi.
Agasanduku k'ubwoko bw'imyenda idakora igishishwa ikozwe na alkali phenolic resin umucanga cyangwa amazi yikirahure cyamazi.Nyuma ya matrix isanzwe hamwe na gari ya moshi iringaniye ya induction kuzimya ubushyuhe, ubukana bwubuso bugera kuri HRC48-58, kandi ubujyakuzimu bukomeye buri hejuru ya 4-6mm (HRC45).Ifite imbaraga zo kwihanganira ingaruka zikomeye no kwihanganira kwambara kubera akazi gakomeye.
