X46Cr13 / 4Cr13: Igipimo ngenderwaho cy'inganda ku mpeta nziza
X46Cr13 (DIN 1.4034, izina ry'Abashinwa 4Cr13) ni icyuma kitagira umugese cya martensitic kandi ibikoresho bikoreshwa cyane mu mpeta y'abahanga birapfa. Icyiganza cyayo si impanuka ahubwo gituruka ku buringanire bwiza bw'imiterere.
Ubukomere. Nyuma yo gukoresha ubushyuhe bwa vacuum, X46Cr13 igera kuri HRC 52 60 ku buso bw'akazi mu gihe igumana ubukomere buhagije bw'imbere. Urugero, imiterere y'inganda za Shanbao, igamije HRC 52 55, mu gihe igiciro cya Hongyang kigera kuri HRC 58 60 binyuze mu gukonjesha vacuum [2], [3].
Ubudahangarwa ku Guturika. Ingano ya chromium (hafi 13%) itanga ubudahangarwa bwiza ku bushuhe, umwuka, n'ibikoresho byo kugaburira byangiza buhoro buhoro kurusha ibyuma bya alloy. Ku biryo byo mu mazi bifite ubushuhe bwinshi, cyangwa ku nganda zikora ahantu hashyushye, ubu budahangarwa ku Guturika bwangiza butuma ubuzima bukomeza [1].
Ubudahangarwa bwo kwangirika. Uruvange rw'ibinyabutabire byinshi bya karuboni na karubide za chromium bikorerwa mu gihe cyo kuvura ubushyuhe bitanga ubuso budashobora kwangirika bukomeza imiterere y'imyobo mu gihe cy'igihe kirekire cyo gukora. Mu igerageza ryo kugereranya, X46Cr13 ring dies irarusha ibyuma bya alloy steel dies mu nkoko zishaje cyane n'ibiryo byo mu mazi [1].
Itegeko rifatika ryo guhitamo. Ku nganda zitanga ibiribwa aho uburyo bw'ibanze bwo kwangirika ari ukwangirika kw'imyobo, kwangirika kw'imbere mu buso, cyangwa gutakaza ubushobozi aho kuba ukwangirika kw'ibinyabutabire X46Cr13 ni yo mahitamo akomeye y'ibikoresho byose. Inyigo yakozwe muri Hongyang Kazakhstan yagaragaje igihe cyo gukora icyuma gifunganye cy'amasaha 880 (ugereranyije n'amasaha 600 ku mashini yasimbuwe) hamwe n'icyuma gifunganye cya X46Cr13, kigaragaza iterambere rya 46.7% [3].
Icyuma cya 20CrMnTi Alloy: Ifarashi y'akazi ihendutse.
20CrMnTi ni icyuma gikozwe mu cyuma gikoreshwa cyane mu gukora ibyuma binini mu nkoko zisanzwe, mu matungo, no mu bintu bimwe na bimwe bikoreshwa mu gutunganya ibinyabuzima aho ingaruka zo kwangirika ari nke kandi igipimo cy’ikiguzi n’imikorere ari cyo kintu cy’ingenzi kigomba kwitabwaho.
Ubukomere. 20CrMnTi itanga ubukomere bwiza cyane, bugira akamaro iyo uruganda rwa pellet rukora munsi y’umutwaro uhindagurika, iyo formula z’ibiryo zirimo uduce duto, cyangwa iyo guhindura imigozi bidashobora guhora bigumana ubuziranenge buhanitse [1].
Ubukomere. Nyuma yo gukaraba no kuzimya, 20CrMnTi igera kuri HRC 55 60 ku buso ifite igice gikomeye cy'imbere. Iyi mvange irwanya kwangirika kw'ubuso mu gihe yinjiza ibintu bishobora kwangirika [2].
Amakuru yerekeye igihe cyo gukora. Mu gihe cyo gukora, impeta ya 20CrMnTi ipfa amasaha 2.000 kugeza 3.000 ku biryo bisanzwe by’inkoko bikomoka ku binyampeke n’amasaha 1.200 kugeza 1.800 ku gukora pellet y’ibiti iciriritse. Ku bikoresho bikurura cyane nk’igishishwa cy’umuceri (ubukana bwa Mohs 7 bitewe n’umusemburo wa silica), igihe cyo gukora gishobora kugabanuka kikagera ku masaha 8.00 kugeza 1.500 [4].
Imbogamizi. Intege nke z'ibanze ni ukwirinda ingese. Mu miterere irimo ubushuhe bwinshi, umunyu, cyangwa ibice bikomoka kuri aside, 20CrMnTi ishobora kwibasirwa n'ingese n'ibinyabutabire bitera ingese ku buso bw'imyobo, bikongera gukururana, bikagabanya umusaruro, kandi bigagabanya igihe cyo gukora neza hatitawe ku mikorere ya mashini [1].
Ibikoresho NTIBIBAYE BYIZA KU GIFUBIKO BY'INGENZI BYO GUTUNGA IMPERATURE
Ni ngombwa gusobanura igitekerezo gisanzwe kitari cyo. Nubwo zimwe mu nganda zikora pellet ziyobora ibyuma bifite imiterere y’impeta (nka GCr15 / 52100) nk'ibikoresho by'impeta, ibi bikoreshwa cyane cyane mu nganda nto zikora biomass. GCr15 ifite imiterere itandukanye yo kwagura ubushyuhe kandi ntigira ubushobozi bwo kurwanya ingese n'ubukomere bukenewe ku nganda zikora peta zikora neza mu gihe cy'inganda. Inganda zikora peta zikora peta zikora peta zikora peta zigomba gukoresha icyuma cya X46Cr13/4Cr13 martensitic stainless steel cyangwa icyuma cya 20CrMnTi alloy steel kuri peta zikora peta [1].
Uburyo bwo gukora: Aho ibikoresho bihuye n'ubuziranenge
Guhitamo ibikoresho ni ngombwa ariko ntibihagije. Uburyo bwo kubitunganya bugena niba imiterere y’ibyo bikoresho ihinduka mu mikorere y’ibikorwa.
Gucura. Gukora icyuma cy'impeta cyiza gitangirana n'icyuma gikozwe mu buryo bwa "premier blank". Abakora ibikoresho by'ingenzi bakoresha icyuma gikozwe mu buryo bwa "premier blank" gifite chromium nyinshi kandi gikozwe mu buryo bwa "premier blank" (HB 180 220). Gucura neza binoza imiterere y'ibinyampeke, bigakuraho imyanda y'imbere, kandi bishobora kongera igihe cy'urupfu ku kigero cya 15% ugereranije n'ibindi bikoresho bitari iby'impeta [5].
Gucukura imbunda. Utwobo dukorwa hakoreshejwe imashini zicukura imbunda za CNC zikora ku muvuduko ugera ku 15.000 RPM. Uburyohe bw'umwobo ni ikintu cy'ingenzi mu bwiza: utwobo duto twongera ubukana, tugabanya umusaruro, kandi twihutisha kwangirika. Inganda zikora ibikoresho by'ingenzi zigera ku buso bwa Ra 0.4 0.8 μm ku rukuta rw'imbere rw'umwobo, zegera ubwiza bwa polish y'indorerwamo [5].
Uburyo bwo Gutunganya Ubushyuhe bwa Vacuum. Uburyo bwo Gutunganya Ubushyuhe ni intambwe y'ingenzi cyane. Gukomera mu buryo bwa vacuum bitandukanye n'uburyo bwo koga mu kirere cyangwa mu bwogero bw'umunyu bituma habaho ubukomere bumwe nta ogisijeni cyangwa gukuraho karubone. Ubu buryo bugamije HRC 52 60 ku buso bw'akazi mu gihe bukomeza gukomera kugira ngo burwanye no kuvunika munsi y'uburyo bwo gukurura ibintu mu buryo bw'ingufu nyinshi [5], [3].
Gutunganya CNC. Nyuma yo gukoresha ubushyuhe, icyuma gikorerwa imashini zitunganya CNC, zigahindura icyuma, zigasya icyuma cy’imbere. Gutunganya icyuma gikoresha imashini zitunganya CNC kugira ngo zibone uburyo bumwe bwo kwinjira mu mwobo, mu gihe icyuma cy’imbere gisya neza kugira ngo gishobore kubona icyuho gihamye hagati y’icyuma n’icyuma mu ruziga rwose [5].
Igenzura ry’Ubuziranenge. Abakora ibikoresho by’ingenzi bagenzura ubukana, ubushobozi bwo kwihanganira uburebure bw’umwobo (± 0.15 mm ku bikoresho bifite ubuziranenge buhanitse), imiterere y’ubuso, n’igipimo cyo gukanda mbere yo kohereza. Bamwe mu bakora ibikoresho baca igipimo cyo gukanda n’urwego rw’ibikoresho ku mubiri w’ibikoresho kugira ngo babikoreshe neza [3].
Guhitamo Ibikoresho Bikwiye: Uburyo bwo gufata ibyemezo
Uburyo bwo gufata ibyemezo mu guhitamo ibikoresho ni ubu bukurikira. Ku biryo bisanzwe by'inkoko cyangwa amatungo ahantu humutse, 20CrMnTi ni yo isabwa nk'amahitamo meza kandi ahendutse. Ku biryo by'inkoko cyangwa amatungo ahantu hakonje cyangwa hahinduka ubushuhe, X46Cr13 cyangwa 4Cr13 ni yo isabwa. Ku biryo byo mu mazi (amafi/amafi) bifite ubushuhe bwinshi, X46Cr13 cyangwa 4Cr13 ni yo isabwa. Ku biti bifite ibyago bike byo kwangirika, 20CrMnTi ni yo isabwa. Ku biryo bikonjesha cyane birimo imyunyu ngugu cyangwa silica, X46Cr13 cyangwa 4Cr13 ni yo isabwa. Ku bijyanye n'igihe ntarengwa cyo gukoresha, X46Cr13 cyangwa 4Cr13 ifite ubushyuhe bwo mu kirere kuri HRC 58 60 ni yo isabwa. Ku bijyanye n'ingengo y'imari iciriritse, 20CrMnTi ni yo isabwa.
