Intengo Yesaphulelo 20CrNiMo Seamless Alloy Steel Pipe
Incazelo emfushane:
I-20CrNiMo iyinsimbi yesakhiwo se-alloy yekhwalithi ephezulu enezakhiwo ezinhle kakhulu zemishini, ukumelana nokugqwala nokumelana nokugqoka.Isetshenziswa kakhulu emikhakheni yemishini, yobunjiniyela, ezokwakha kanye nezokuvikela imvelo.Amandla ayo aphezulu, ukuqina okuhle kanye ne-ductility kuyenza ikwazi ukugcina impilo ende yesevisi ezindaweni ezinokhahlo futhi imelane nemithwalo ephezulu, ihlinzeka ngokusekela okuqinile ekuthuthukisweni kwemboni yesimanje nobunjiniyela.
Njengoba sisekelwa iqembu le-IT elithuthuke kakhulu nelichwepheshile, singahlinzeka ngosekelo lwezobuchwepheshe ekuthengisweni kwangaphambilini nangesevisi yangemuva kokuthengisa Ngenani Lesaphulelo 20CrNiMo Seamless Alloy Steel Pipe, Sizozama ukugcina isimo sethu esihle njengabahlinzeki bezixazululo abangcono kakhulu. emhlabeni.Uma unemibuzo noma imibono, qiniseka ukuthi uxhumana nathi ngokukhululekile.
Ngokusekelwa iqembu le-IT elithuthuke kakhulu nelichwepheshile, singahlinzeka ngosekelo lobuchwepheshe ekuthengisweni kwangaphambilini nangesevisi yangemuva kokuthengisaChina 20CrNiMo Ingxubevange Ipayipi Seamless Steel, Ukusebenza kanzima ukuze uqhubeke nokwenza inqubekelaphambili, ukusungula izinto ezintsha embonini, yenza yonke imizamo ebhizinisini elisezingeni lokuqala.Sizama konke okusemandleni ethu ukwakha imodeli yokuphatha yesayensi, ukufunda ulwazi oluningi lochwepheshe, ukuthuthukisa imishini yokukhiqiza ethuthukisiwe nenqubo yokukhiqiza, ukwakha imikhiqizo yekhwalithi yokuqala, intengo enengqondo, ikhwalithi ephezulu yesevisi, ukulethwa okusheshayo, ukukunikeza ukudala. inani elisha .

I-20CrNiMo ekuqaleni yayiyinombolo yensimbi 8620 kumazinga aseMelika e-AISI kanye ne-SAE.Ukusebenza kokuqina kufana nalokho kwensimbi ye-20CrNi.Nakuba okuqukethwe kwe-Ni ensimbi kuyingxenye yensimbi engu-20CrNi, ngenxa yokwengezwa kwenani elincane le-Mo element, ingxenye engenhla ye-austenite isothermal transformation curve iya kwesokudla;futhi ngenxa yokwanda okufanele kokuqukethwe kwe-Mn, ukuqina kwale nsimbi kusekuhle kakhulu, namandla Ibuye iphakeme kunensimbi engu-20CrNi, futhi ingashintsha insimbi engu-12CrNi3 ukuze kukhiqizwe izingxenye ze-carburized kanye nezingxenye ze-cyanide ezidinga ukusebenza okuyisisekelo okuphezulu.I-20CrNiMo ingakwazi ukumelana nezinga lokushisa elithile ngaphezu kwezakhiwo ezinhle eziphelele ngoba iqukethe i-molybdenum.
1. Embonini yokukhiqiza, kuvame ukusetshenziselwa ukwenza izingxenye ezingaphansi komthwalo omkhulu, ukucindezeleka okukhulu, nokugqokwa okuphezulu, njengamagiya, ama-shafts, ama-bearings, njll. Amandla azo aphezulu kanye nokuqina okuhle kwenza lezi zingxenye zigcine impilo ende yesevisi ezindaweni zokusebenza ezinzima.Ngaphezu kwalokho, iphinde ibe nokumelana nokukhathala okuhle kakhulu nokumelana nokugqwala, okungamelana ngokuphumelelayo nokuguguleka kwemvelo yangaphandle nokuqinisekisa ukusebenza okuzinzile kwemishini.
2. Emkhakheni wokwakha, le nsimbi isetshenziswa kakhulu ekwakhiweni kwezakhiwo ezinkulu ezifana namabhuloho nezakhiwo eziphakeme ngenxa yamandla ayo aphezulu kanye ne-ductility enhle.Kulezi zakhiwo, zingakwazi ukumelana nokucindezela okukhulu nokungezwani, ziqinisekise ukuphepha nokuzinza kwesakhiwo.
3. Ngaphezu kwalokho, ngokuthuthukiswa kokuqwashisa ngemvelo, izicelo emkhakheni wokuvikelwa kwemvelo ziya ngokuya ziba ziningi.Isibonelo, ezimotweni zamandla amasha, ingasetshenziswa ukwenza izingxenye ezibalulekile ezifana namamotho kanye nezinciphisi, okunomthelela ekuhambeni okuluhlaza.Iphinde idlale indima ebalulekile emishinini yokuvikela imvelo efana nokuhlanza indle kanye nokwelashwa kwegesi engcolile, ukunikeza ukwesekwa okuqinile kokuthuthukisa izinga lemvelo.
1. Izingxenye ezibalulekile zesakhiwo, njengegiya lokuhlala ezindizeni, amathangi nezingxenye zemoto yezikhali.
2. Izixhumi nezixhumi ezinamandla aphezulu.
3. Amagiya okulayisha aphezulu nama-bearings.
Ukucisha 850ºC, amafutha abandayo;Ukushisa ku-200ºC, ukupholisa umoya.
Ukulethwa ekwelapheni ukushisa (okujwayelekile, ukuthuthwa kwe-anneal noma ukushisa okuphezulu) noma kungekho isimo sokwelashwa kokushisa, isimo sokulethwa sizoboniswa kwinkontileka.
Njengoba sisekelwa iqembu elithuthuke kakhulu nelichwepheshile, singahlinzeka ngosekelo lobuchwepheshe ekuthengisweni kwangaphambilini nangesevisi yangemuva kokuthengisa.
