AMAKURU

Mubikorwa byo gukora, isahani yumusaya ikunze kwambarwa, bigira ingaruka kumikorere isanzwe yimisaya. Uru rupapuro rwiga ibyuma bya karuboni nkeya byuma byuma byangiza, kandi bikaganira ku itegeko rihindura ubukana bw’isahani no kwambara, kugira ngo hamenyekane ubushyuhe bwo kuzimya iyo isahani yo kwambara yageze ku rwego rwiza.

 Guhitamo ibikoresho by'urwasaya

1. Mu nganda, isahani yimukanwa hamwe nisahani ihamye ikozwe mu cyuma kinini cya manganese idashobora kwangirika, icyuma kinini cyo gutwara hamwe na eccentric bearing liner bikozwe mu mavuta ya babbitt, naho isahani y'urwasaya ikozwe mu cyuma kugira ngo itezimbere kuramba. Isahani y'urwasaya rw'urwasaya rugomba kuba muri serivisi mubihe bidashobora kwihanganira kwambara, birwanya ingaruka kandi bikomeye. Inganda zinyuranye zikoresha ibikoresho bya plaque zitandukanye, nk'icyuma kinini cya manganese, icyuma giciriritse cya manganese, icyuma giciriritse, icyuma giciriritse giciriritse giciriritse cyangirika kandi cyuma cya chromium.

2. Icyuma giciriritse giciriritse-cyuma-kirinda kwangirika kiboneka hiyongereyeho ibintu bitandukanye bivanze nka Cr, Si, Mn, Mo, V hashingiwe ku byuma biciriritse-karubone, kandi ibivanze byose biri munsi ya 5 %. Ubu bwoko bwa karubone yo hagati ya karubone nkeya-y-ibyuma-idashobora kwangirika irashobora guhinduranya neza ibirimo karubone bitandukanye hamwe nibigize ibintu bivanze, bityo irashobora guhuzwa nuburyo butandukanye bwo kuvura ubushyuhe kugirango ibone ibintu bitandukanye byubukanishi, bityo ikurura abantu benshi kandi ikabishyira mubikorwa. Muri iyi nyandiko, hasuzumwe uburyo bwo kurwanya imyuka ya karubone ntoya ya ZG42Mn2Si1REB, kandi haganiriwe ku itegeko ryo guhindura ubukana no kwambara hamwe n’ubushyuhe bwo kuzimya, maze haboneka uburyo bwiza bwo kuvura ubushyuhe.

 Tahitamo uburyo bwo kuvura ubushyuhe

Ukurikije ibiranga ibyuma bya ZG42Mn2Si1REB, imiterere ya martensite yabonetse nyuma yo kuzimya ifite ubukana bwinshi kandi irwanya kwambara neza. Ingingo eshatu z'ubushyuhe bwa 870 ℃, 900 ℃ na 930 ℃ zatoranijwe kugirango zivurwe, kandi ubushyuhe bwubushyuhe bwashyizwe hamwe kuri 230 ℃. Kuberako ibikoresho bitarimo Mo element, kugirango tumenye gukomera, 5% Nacl igisubizo gikoreshwa mugukonja.

 Ibisubizo nisesengura

1. Ingaruka zo kuzimya ubushyuhe ku gukomera no kwambara birwanya

Ubukomezi bw'icyitegererezo bwazimye ku bushyuhe butandukanye bwapimwe na metero ya HR-150A ya Rockwell, ipima amanota 5 buri mwanya hanyuma ifata agaciro kagereranijwe. Byagaragaye ko hamwe no kwiyongera kwubushyuhe bwo kuzimya, ubukana bwo kuzimya bwabanje kwiyongera hanyuma bugabanuka. Iyo ubushyuhe bwo kuzimya ari 870 ℃, ubukana ni HRC53. Iyo ubushyuhe bwo kuzimya buzamutse bugera kuri 900 ℃, ubukana nabwo buzamuka kuri HRC55. Birashobora kugaragara ko ubukana bwiyongera hamwe no kwiyongera kwubushyuhe; Iyo ubushyuhe bukomeje kwiyongera kugera kuri 930 ℃, ubukana buragabanuka kuri HRC54, kandi ushobora gusanga ubukana buri hejuru iyo buzimye kuri 900 ℃. Kubwibyo, hamwe no kwiyongera kwubushyuhe, kugabanuka ibiro biragabanuka. Iyo ubushyuhe bukomeje kuzamuka kugera kuri 930 ℃, gutakaza ibiro byiyongera kugera kuri 3.5mg. Birashobora kugaragara ko iyo yazimye kuri 900 ℃, ubukana bwayo buri hejuru kandi gutakaza ibiro birabura. Icyuma giciriritse giciriritse gike cyihanganira kwambara ZG42Mn2Si1REB gifite imyambarire myiza yo kwambara, ibyo bikaba byerekana kandi ko inzira muriki gihe aribwo buryo bwiza bwo kuvura ubushyuhe.

2. Kugereranya imyambarire irwanya imyuka yo hagati ya karubone ntoya hamwe nicyuma kinini cya manganese

Kugirango ugaragaze imyambarire isumba iyindi ya karubone ikomatanya ibyuma bya ZG42Mn2Si1REB, ibi bikoresho bigereranwa nicyuma kinini cya manganese ZGMn13. Muri byo, ZG42Mn2Si1REB yapimwe hakurikijwe imiterere y’ikoranabuhanga yavuzwe haruguru yo kuzimya 900 ℃ no gushyuha kuri 230 and, naho ibyuma bya manganeze ZGMn13 byavuwe hakoreshejwe amazi. Ibisubizo byubushakashatsi byerekana ko kwihanganira kwambara byikubye inshuro 1.5 iyanyuma, ibyo bikaba byerekana ko isahani yumusaya wicyuma giciriritse giciriritse giciriritse yakoresheje imbaraga zose z ibikoresho kandi ikagira imbaraga zo kwambara mugihe gikwiye cyo kuvura ubushyuhe.

Kubijyanye nigiciro cyibikoresho, ibyuma bya manganese birebire bigera kuri 13% Mn, bityo rero bigomba gukoresha ibintu byinshi bivanze. Ugereranije nicyuma kinini cya manganese, icyuma giciriritse giciriritse giciriritse ZG42Mn2Si1REB kirimo ibintu 3% ~ 4% gusa bivanze, kandi ntabwo birimo ibintu bya Cr na Mo bihenze cyane, kubwibyo bifite inyungu nziza zo guhatanira. Byongeye kandi, urebye uburyo bwo gutunganya ubushyuhe, icyuma giciriritse giciriritse giciriritse kizimya 900 ℃ kandi kigashyirwa kuri 230 ℃, mugihe amazi akaze yo kuvura ibyuma bya manganeze akenshi arenga 1000 ℃, bityo ubushyuhe bwo kuzimya bwa mbere buri hasi, igihe cyo gushyuha ni kigufi, kandi ingaruka zo kuzigama ingufu ziratangaje. Uburyo bwiza bwo gutunganya ubushyuhe bwakoreshejwe ku isahani ya crusher, bigaragara ko byateje imbere imyambarire, kandi uburyo bwo gusimbuza isahani ya jawusi bwongerewe kuva kuri 150d bugera kuri 225d, kandi inyungu zigaragara mu bukungu.

Binyuze mu bushakashatsi bwakozwe ku kurwanya kwangirika kw'isahani ya karubone yo hagati ya karuboni ntoya ivanze na jaw crusher, ibisubizo byerekana ko iyo yazimye kuri 900 ℃, microstructure nyuma yo kuzimya ni martensite, muri iki gihe, ubukana buri hejuru, uburemere bwo kwambara igihombo kiri hasi, kandi kwihanganira kwambara nibyiza.

Shanvim nkumuntu utanga isi yose ya crusher yambaye ibice, dukora cone crusher yambaye ibice kubirango bitandukanye bya crusher. Dufite imyaka irenga 20 yamateka murwego rwa CRUSHER YAMBARA IBICE. Kuva mu 2010, twohereje muri Amerika, Uburayi, Afurika ndetse no mu bindi bihugu ku isi.
