Imigoqo eyindilinga yensimbi egoqiwe engu-GCr15

I-GCr15 insimbi evamile esetshenziselwa ukukhiqiza amabhola namaringi okuthwala. Umkhiqizo unezici ze-uniform-chemical composition, iphesenti eliphansi lezinto eziyingozi, ukuhlanzeka okuphezulu, i-carbide esabalaliswe kahle, ikhwalithi enhle yendawo. Iphinde ibe nezici zobubanzi obubanzi bepulasitiki, ikhwalithi yokwelapha ukushisa ezinzile, umfaniswano, nobulukhuni obuphezulu, ukumelana nokugqoka okuphezulu, amandla aphezulu okuthinta ukukhathala. Inesakhiwo esihle kakhulu sokusebenza ngemuva kwe-spheroidize annealing. Insimbi ene-GB GCr15 iyinsimbi ye-GB ejwayelekile ye-Alloy Bearing, ingeyekhabhoni ephezulu yekhwalithi ephezulu, i-alloy chromium, insimbi ye-manganese. Izakhiwo ze-GB GCr15 ziyi-chromium, ukucaciswa kwensimbi ye-manganese alloy. I-GCr15 ilingana ne-AISI 52100, DIN 100Cr6. Izinhlelo zokusebenza eziningi zingashintshana.

Ukwakheka kwamakhemikhali

C(％)	0.95～1.05	Si(％)	0.15～0.35	Mn(％)	0.25～0.45	P(％)	≤0.025
S(％)	≤0.025	Cr(％)	1.40～1.65

Izakhiwo Zemishini

Izakhiwo zemishini yensimbi ene-GB GCr15 ene-annealed (evamile yensimbi) zivezwe kuthebula elingezansi:

I-tensile	Veza	I-modulus yobuningi	Shear modulus	Isilinganiso sikaPoisson	I-Thermal conductivity
I-MPa	Mpa	I-Gpa	I-Gpa		W/mK
520	415 min	140	80	0.27-0.30	46.6

Ukwelashwa Ukushisa Okuhlobene

• Ukufakwa kwensimbi ene-GCr15 Alloy

Kushisisa kancane ku-790-810 ℃ futhi uvumele izikhathi ezanele, vumela insimbi ukuthi ifudunyezwe kahle, Bese upholisa kancane esithandweni. Izindlela ezihlukene zokudonsa zizothola ubulukhuni obuhlukile.Insimbi ene-GCr15 izothola Ukuqina MAX 248 HB (ukuqina kweBrinell).

• Ukucisha kanye nezinga lokushisa kwe-GCr15 Alloy ephethe insimbi

Kushisisa kancane ukuya ku-860°C, Bese ukucisha ngamafutha thola ubulukhuni obungu-62 kuya ku-66 HRc. Ukushisa okuphezulu kokushisa: 650-700 ℃, kupholile emoyeni, thola ubulukhuni 22 kuya ku-30HRC. Izinga lokushisa eliphansi: 150-170 ℃, Cool  ku-ari, thola 61-66HRC ubulukhuni.

• Umsebenzi oshisayo nomsebenzi obandayo we-GCr15 Alloy bearing steel

Insimbi ye-GB GCr15 ingashisa isebenze ku-205 kuya ku-538°C, i-GCr15 Bearing steel ingabanda kusetshenzwe kusetshenziswa amasu avamile ezimeni ezivaliwe noma ezijwayelekile.

Izinhlelo zokusebenza

Insimbi ye-GB GCr15 isetshenziswa kabanzi emikhakheni ehlukahlukene esetshenziswa kumabheringi emishini ejikelezayo. Izinhlelo zokusebenza ezijwayelekile ezifana nemizimba yama-valve, amaphampu nokufakwa, umthwalo omkhulu wamasondo, amabhawudi, amabhawodi anamakhanda akabili, amagiya, injini yomlilo yangaphakathi. Izitimela zikagesi, amathuluzi omshini, ogandaganda, okokusebenza kwensimbi okugingqika, umshini oyisicefe, imoto yesitimela, kanye nemishini yezimayini yokudlulisa shaft ebholeni lensimbi, i-roller kanye nomkhono we-shaft, njll.
