Wigeze utekereza kubikoresho bikoreshwa mu ndobo?Muri iki kiganiro, tuzaganira kubikoresho bikoreshwa cyane mumapine, impande, gukata impande, amazu n'amenyo yindobo.

Amabati

Ubucukuzi bwa Excavator busanzwe bukozwe muri AISI 4130 cyangwa 4140 ibyuma.Icyuma cya AISI 4000 nicyuma cya chrome molybdenum.Chromium itezimbere kwangirika no gukomera, mugihe molybdenum nayo itezimbere imbaraga no gukomera.

Umubare wambere, 4, ugereranya urwego rwibyuma nibigize nyamukuru bivanze (muriki gihe, chromium na molybdenum).Umubare wa kabiri 1 ugereranya ijanisha ryibintu bivangavanze, bivuze nka 1% chromium na molybdenum (kubwinshi).Imibare ibiri yanyuma ni imyuka ya karubone mu kwiyongera kwa 0.01%, bityo AISI 4130 ifite 0,30% karubone na AISI 4140 ifite 0.40%.

Ibyuma byakoreshejwe birashoboka ko byakorewe hamwe no gukomera.Ubu buryo bwo kuvura ubushyuhe butanga ubuso bukomeye hamwe no kwihanganira kwambara (58 kugeza 63 Rockwell C) hamwe nimbere yimbere kugirango irusheho gukomera.Menya ko ibihuru mubisanzwe bikozwe mubintu bimwe na pin.Amapine ahendutse arashobora gukorwa muri AISI 1045. Iki nicyuma giciriritse giciriritse gishobora gukomera.

Gucukura indobo kuruhande no gukata impande

Impande zindobo nicyuma mubisanzwe bikozwe mubisahani bya AR.Ibyiciro bizwi cyane ni AR360 na AR400.AR 360 nicyuma giciriritse giciriritse giciriritse cyakorewe ubushyuhe kugirango gitange imyambarire myiza nimbaraga zikomeye.AR 400 nayo ivurwa nubushyuhe, ariko itanga kwambara no gukomera kwimbaraga.Ibyuma byombi birakomeye kandi byitondewe kugirango bigere ku bicuruzwa byiza byindobo.Nyamuneka menya ko umubare nyuma ya AR ari Brinell ikomeye yicyuma.

Igikonoshwa cy'indobo

Inzu y'indobo isanzwe ikorwa muri ASTM A572 Icyiciro cya 50 (rimwe na rimwe cyanditswe A-572-50), kikaba ari imbaraga nyinshi cyane ibyuma bivangavanze.Icyuma kivanze na niobium na vanadium.Vanadium ifasha gukomeza ibyuma bikomeye.Uru rwego rwibyuma nibyiza kubishishwa byindobo kuko bitanga imbaraga nziza mugihe ipima munsi yicyuma cyagereranywa nka A36.Biroroshye kandi gusudira no gushushanya.

Amenyo y'indobo

Kugirango tuganire kubyo amenyo yindobo akozwe, ni ngombwa kumva ko hari inzira ebyiri zo gukora amenyo yindobo: guta no guhimba.Amenyo yindobo ashobora gukorwa mubyuma bito hamwe na nikel na molybdenum nkibintu nyamukuru bivanga.Molybdenum itezimbere gukomera nimbaraga zicyuma kandi irashobora no kugabanya uburyo bumwe na bumwe bwo kwangirika.Nickel itezimbere imbaraga, gukomera no gufasha kwirinda ruswa.Birashobora kandi kuba bikozwe mubyuma bya isothermal byazimye ibyuma byavuwe ubushyuhe kugirango bongere imbaraga zo kwambara no gukomera.Amenyo y'indobo yahimbwe nayo akozwe mubyuma bivangwa nubushyuhe, ariko ubwoko bwibyuma buratandukanye kubabikora.Kuvura ubushyuhe bitezimbere imikorere yimyambarire kandi byongera imbaraga zingaruka.

Umwanzuro

Indobo zicukura zikozwe mubikoresho byinshi bitandukanye, ariko ibyo bikoresho byose nibyuma cyangwa ubwoko bwicyuma.Ubwoko bwibikoresho byatoranijwe ukurikije uburyo igice cyapakiwe kandi gikozwe.
