Intshayelelo yegama lemveliso yokuthwala intsimbi

Ukuthwalaintsimbi isetyenziselwa ukwenza iibhola, iirola kunye namakhonkco okuzala. Ukuthwala intsimbi kunobunzima obuphezulu kunye nobunye kunye nokumelana nokunxiba, kunye nomda ophezulu we-elastic. Ukuhambelana kweekhemikhali zentsimbi yokuthwala, umxholo kunye nokuhanjiswa kwezinto ezingenayo i-metallic inclusions, kunye nokuhanjiswa kwe-carbides kungqongqo kakhulu. Ngomnye wemigangatho yentsimbi engqongqo kakhulu kuyo yonke imveliso yentsimbi.

Amagama emveliso eqhelekileyo yeukuzalaiintsimbi ziquka GCr15, AISI52100, SUJ2, njl.

1. GCr15

I-GCr15 yintsimbi ye-alloy enobunzima obuphezulu, ukumelana nokunxiba kakuhle kunye nokumelana nobushushu obuphezulu. Amacandelo ayo aphambili yiCr, Mn, Si, W, Mo, V kunye nezinye izinto. Intsimbi ye-GCr15 ihlala isetyenziselwa ukwenza iindawo ezikumgangatho ophezulu ezinje ngeebheringi ezichaneke kakhulu, iigiya, iindawo ezidityanisiweyo zendalo iphela, kunye neenjini zemoto. Isetyenziswa kakhulu kwishishini lokwenziwa koomatshini.

II. AISI52100

I-AISI52100 luhlobo lwentsimbi ye-carbon chromium ephezulu, eyaziwa ngokuba yi-high-carbon chromium alloy steel. Amacandelo ayo aphambili zizinto ezifana ne-Cr, C, Si, Mn, P, kunye ne-S. AISI52100 inamandla amakhulu, ubunzima obuphezulu kunye nokumelana nokugqwesa okugqwesileyo, kwaye isetyenziswa ngokubanzi ekwenzeni iindawo ezikumgangatho ophezulu ezifana neebheringi, ukunciphisa, iigiya, njl.

3. SUJ2

I-SUJ2 ngumgangatho woshishino waseJapan ophethe intsimbi, eyaziwa ngokuba yi-SUJ2 yensimbi kwi-JIS G 4805. Amacandelo ayo aphambili zizinto ezifana ne-Cr, Mo, C, Si, kunye ne-Mn. I-SUJ2 yentsimbi inobunzima obuphezulu, ukuxhathisa okuphezulu kunye nomthamo ophezulu wokuthwala umthwalo, kwaye isetyenziselwa ngokubanzi ukuveliswa kweebheringi ezichanekileyo, iigiya, i-universal joints, iinjini zemoto kunye nezinye iindawo.

Phakathi kwezi ntlobo zintathu zingasentla zokuthwala intsimbi, i-GCr15 yeyona nto isetyenziswa kakhulu e-China, kuba ineenzuzo zexabiso eliphakathi, ukusebenza kakuhle kokusebenza kunye nokumelana nokugqoka okuphezulu; I-AISI52100 yintsimbi esetyenziswa ngokuqhelekileyo e-United States ngenxa yenkqubo yokuvelisa ekhulile kunye nomgangatho othembekileyo; I-SUJ2 yintsimbi ethwala isetyenziswa ngokuqhelekileyo eJapan ngenxa yokusebenza kwayo okuzinzile, ukuchaneka okuphezulu kunye nobomi obude.

Isishwankathelo, ezahlukeneyoukuzalaamagama entsimbi aneempawu zawo ezizodwa kunye neenzuzo, kwaye amashishini kufuneka akhethe intsimbi efanelekileyo ngokweemfuno zabo xa ekhetha uhlobo.
