Iinzuzo zethu ngamaxabiso aphantsi, iqela lokuthengisa eliguqukayo, i-QC ekhethekileyo, iifektri ezomeleleyo, iimveliso ezikumgangatho ophezulu kunye neenkonzoChina 42CrMo Steel Pipe, Amava ethu asenza sibaluleke emehlweni ethu abathengi.Umgangatho wethu uyazithetha ngokwawo kwiipropathi ezinje ukuba awujiki, uphalaze okanye uwohloke, ukuze abathengi bethu bahlale bezithembile ngelixa bebeka iodolo.

Ayinayo i-brittleness ecacileyo yomsindo, i-deformation encinci ngexesha lokucima, umda wokudinwa okuphezulu kunye nokuchasana kweempembelelo ezininzi emva kokucima kunye nonyango olushushu.Umbhobho we-alloy we-42CrMo ongenamthungo unefuthe elihle lokuqina kwiqondo lobushushu eliphantsi kunye namandla anyukayo aphezulu kunye namandla okunyamezela kwiqondo lobushushu eliphezulu.Ukucima umphezulu emva kokucinywa kunye nokufudumeza ngokuqhelekileyo kusetyenziswa njengeskimu sonyango lobushushu kwimibhobho yealloy engenamthungo ye-42CrMo.

Ingxubevange yentsimbi ekhethekileyo:41Cr4,25CrMo4,30CrMo4,34CrMo4,42CrMo4

OD: 20-660mm WT: 2.3-100mm L: 5.8M, 6M, 11.8M, 12M okanye nabuphi na ubude obuchaziweyo.

Isicelo: Umatshini, ubunjineli ngokubanzi, ingalo yecrane, amahlathi, ii-Cylinders ezahlukeneyo, ii-Conveyor Rolls, i-Hollow Shafts, i-Hollow Parts kunye nezixhobo, iiNti, iiringi, njl.

Ukusetyenziswa kwepayipi ye-alloy ye-42CrMo engenamthungo: insimbi ekhethekileyo esetyenziselwa iibhulorho "42CrMo", intsimbi ekhethekileyo yeegidi zemoto "42CrMo", kunye nentsimbi ekhethekileyo kwiinqanawa zoxinzelelo "42CrMo".Olu hlobo lwensimbi luphucula iimpawu zemishini yensimbi ngokulungelelanisa umxholo wekhabhoni (c).Ngoko ke, ngokubhekiselele kumxholo wekhabhoni, olu hlobo lwensimbi lunokwahlulwa lube: intsimbi ephantsi yekhabhoni - umxholo wekhabhoni ngokuqhelekileyo ungaphantsi kwe-0.25%, njenge-10 kunye ne-20 yensimbi;Insimbi ye-carbon ephakathi - umxholo wekhabhoni uphakathi kwe-0.25 kunye ne-0.60%, njenge-35 kunye ne-45 yensimbi;Intsimbi yekhabhoni ephezulu - umxholo wekhabhoni ungaphezulu kwe-0.60%.Olu hlobo lwentsimbi alusetyenziswanga ukwenza imibhobho yentsimbi.

Usetyenziso oluqhelekileyo
Ifanelekile ukwenza iimbumba zeplastiki ezinkulu kunye neziphakathi ezifuna amandla athile kunye nokuqina.

Ukunyamezela Ubude:
Xa Ubude bulingana ne-6000mm, Ukunyamezela 0/+10
Xa 6 000 < L = 12 000, Ukunyamezela 0/+15
Xa > 12 000,Ukunyamezela 0/+ ngesivumelwano
Ukucaciswa kwenkqubo kunye neempawu ezibonakalayo ze-42CrMo zentsimbi yombhobho
I-42CrMo ipayipi yensimbi, umxholo wekhabhoni: 0.38 ～ 0.45%, i-silicon: 0.17 ～ 0.37%, i-manganese: 0.50 ～ 0.80%.

I-42CrMo yentsimbi yombhobho yentsimbi eyomelele kakhulu, inamandla aphezulu kunye nokuqina, ukuqina okuhle, akukho brittleness ecacileyo yokudinwa, umda wokudinwa okuphezulu kunye nokumelana neempembelelo ezininzi emva kokucima kunye nonyango olushushu, kunye nokuqina okuhle kobushushu obuphantsi.

Intsimbi ifanelekile ukuvelisa iimbumba zeplastiki ezinkulu kunye neziphakathi ezifuna amandla athile kunye nokuqina.I-brand yayo ehambelana nemigangatho yezizwe ngezizwe: i-42CrMo4 ihambelana ne-brand yaseJapan: i-scm440 ihambelana ne-brand yaseJamani: i-42CrMo4 ihambelana malunga ne-brand yaseMelika: iimpawu ze-4140 kunye nobubanzi besicelo: amandla aphezulu, ukuqina, ukuqina okulungileyo, ukuguqulwa okuncinci ngexesha lokucima, amandla aphezulu kunye amandla okunyamezela kwiqondo lokushisa eliphezulu.Isetyenziselwa ukwenza iifogi ezinamandla aphezulu kunye nokucinywa okukhulu kunye nokutshisa okunqamlezayo kune-35CrMo yentsimbi, efana negiya enkulu ye-locomotive traction, igiya yokuhambisa ye-supercharger, i-axle yangasemva, intonga yokudibanisa kunye ne-spring clamp enomthwalo omkhulu, i-drill pipe edibeneyo kunye isixhobo sokuloba i-oyile nzulu kakuhle ngaphantsi kwe-2000m, kunye nokungunda kumatshini ukugoba.
