Mubihe bisanzwe, uburinganire bwibipimo byerekana neza ibintu byinshi nkuburyo bwo gukina, ibikoresho byo guteramo, gukora ibishushanyo, gukora ibishishwa, guteka, gusuka, nibindi. casting.Ibi biganisha ku gutandukana muburyo buringaniye bwa casting uhereye kubisabwa.Ibikurikira nimpamvu zishobora gutera inenge muburyo bufatika bwo gukina neza:
(1) Ingaruka yimiterere ya casting: a.Gutera urukuta uburebure, igipimo kinini cyo kugabanuka, urukuta ruto rwo guta, igipimo gito cyo kugabanuka.b.Igipimo cyo kugabanuka kubuntu ni kinini, kandi igipimo cyo kugabanuka ni gito.
(2) Ingaruka zo gukina ibikoresho: a.Iyo hejuru ya karubone iri mu bikoresho, ni nako igipimo cyo kugabanuka ku murongo, no kugabanuka kwa karubone, niko umuvuduko ugabanuka.b.Igipimo cyo kugabanuka cyibikoresho bisanzwe nibi bikurikira: igipimo cyo kugabanuka K = (LM-LJ) / LJ × 100%, LM nubunini bwa cavit, naho LJ nubunini bwa casting.K yibasiwe nibintu bikurikira: ibishashara ibishashara K1, imiterere ya K2, ubwoko bwa K3, gusuka ubushyuhe K4.
(3) Ingaruka zo gukora ibishushanyo kumurongo wo kugabanuka kumurongo: a.Ingaruka yubushyuhe bwo gutera ibishashara, igitutu cyo gutera ibishashara, hamwe nigitutu cyo gufata umwanya mubunini bwishoramari nicyo kigaragara cyane mubushyuhe bwo gutera ibishashara, hagakurikiraho igitutu cyo gutera ibishashara, kandi igihe cyo gufata igitutu cyizewe Nyuma yishoramari rimaze gushingwa, ifite ingaruka nke kubunini bwanyuma bwishoramari.b.Igipimo cyo kugabanuka kumurongo wibishashara (mold) ni 0.9-1.1%.c.Iyo ifaranga ryishoramari ribitswe, hazakomeza kubaho kugabanuka, kandi agaciro kayo kagabanutse ni hafi 10% yikiguzi cyose, ariko iyo kibitswe mumasaha 12, ingano yishoramari iba ihagaze neza.d.Igabanuka rya radiyo yibishashara ni 30-40% gusa yikigereranyo cyo kugabanuka.Ubushyuhe bwo gutera ibishashara bugira uruhare runini ku gipimo cyo kugabanuka ku buntu kuruta igipimo cyo kugabanuka (ubushyuhe bwiza bwo gutera ibishashara ni 57-59 ℃, Ubushyuhe bwinshi, niko kugabanuka).
.Kubera coefficient ntoya yo kwaguka, 4,6 × 10-6 / only gusa, barashobora kwirengagizwa.
