27 simamashubhu ensimbi angenamthungo, isib27SiMn amashubhu ensimbi angenamthungo, zingenye yezinto zokwakha amashubhu ensimbi angenamthungo.Okuqukethwe kwekhabhoni kuphakathi kuka-0.24 no-0.32%.Umugqa owodwa we-simn kungenxa yezakhi ezinhlanu (i-carbon C, i-silicon Si ne-manganese).Ku-Mn, i-phosphorus P, ne-sulphur S, okuqukethwe kwe-silicomanganese cishe ku-1.10 kuya ku-1.40%.Ipayipi elingenamthungo le-27simn lilungele isitshalo samandla, isitshalo esibhayela, imboni yamakhemikhali, imoto, izesekeli zomkhumbi.
27simn insimbi engenamthungo ithiyori yensimbi yesisindo ifomula yensimbi engenamthungo ngemitha ngesisindo W=0.02466*S(DS)
Incazelo Yophawu: D = Ububanzi bangaphandle S = Isibonelo sokubala ukujiya kodonga: Epayipini lensimbi elingenamthungo elinobubanzi obungaphandle obungu-60mm nogqinsi oluyi-4mm, bala isisindo nge-m.
Isisindo m=0.02466*4*(60-4)=5.52Kg

Intengo yamashubhu ensimbi angenamthungo icishe ibe ngu-500-800 yuan/ton ephakeme kunaleyo yamashubhu ashiselwe ngomthungo oqondile, futhi intengo yamashubhu ensimbi angenamthungo ingaphezu kuka-800-1200 yuan/thani ngaphezu kwamashubhu ensimbi angenamthungo.Inqubo yokukhiqiza ipayipi lensimbi engenamthungo |Ipayipi lensimbi elingenamthungo litholakala ngokuyinhloko ngokunciphisa ukungezwani, futhi inqubo yokunciphisa ukungezwani kuyinqubo eqhubekayo yokugingqa lapho isisekelo sensimbi esingenalutho singenayo i-mandrel.Ngokwesisekelo sokuqinisekisa ikhwalithi yokushisela kweshubhu likamama, inqubo yokunciphisa ukushuba kwepayipi elishiselwe ukushisa lonke ipayipi elishiselwe libe ngama-degrees Celsius angama-950 noma ngaphezulu, bese kuba ngamadayimitha ahlukahlukene angaphandle nezindonga isinciphisi sokungezwani (ingqikithi yamaphasi angama-24 wesinciphisi esilula).Ishubhu eliqediwe eliwugqinsi, ishubhu lensimbi eligoqiwe elishisayo elikhiqizwe yile nqubo kanye nepayipi elishiselwe imvamisa ephezulu ahlukene kakhulu.Ngemuva kokushisa esithandweni sokushisa, isakhiwo se-metallographic kanye nezakhiwo zemishini ye-weld kanye nensimbi yomzali ingahambisana ngokuphelele.Ukugingqika kwesibili kokunciphisa ukungezwani nokulawula okuzenzakalelayo kwenza ukunemba kobukhulu bepayipi (ikakhulukazi ukuzungeza kwepayipi nokunemba kokuqina kodonga) kube ngcono kunepayipi elifanayo elingenamthungo.Amashubhu e-Fluid namashubhu obhayela akhiqizwa emazweni athuthukile emhlabeni amukele inani elikhulutube ashiselwe izinqubo Seamless.Ngokuthuthuka komphakathi, amashubhu ashiselwe ezifuywayo ashiselwe kancane kancane athathe indawo yamashubhu angenamthungo.
Ipayipi lensimbi elingenamthungo liwuhlobo lwensimbi ende enengxenye engenalutho futhi engenamthungo nxazonke.Insimbi inengxenye engenalutho, inqwaba yamapayipi asetshenziselwa ukuthutha uketshezi, njengokulethwa kukawoyela, igesi yemvelo, igesi, amanzi nezinye izinto eziqinile njengamapayipi.Ipayipi elingenamthungo lihlukaniswe ngamashubhu agoqelwe ashisayo, amashubhu agoqelwe ngabandayo, amashubhu adonswa abandayo, amashubhu akhishiwe, ukugqekezwa kwamapayipi.Ipayipi lensimbi elingenamthungo lokudlulisa uketshezi lisetshenziselwa ukuthutha amanzi, uwoyela, igesi nolunye uketshezi ngokuvamile oluvamise ukuthuthwa ipayipi lensimbi elingenamthungo.Ipayipi lensimbi engenamthungo eliphansi neliphakathi lisetshenziselwa ukwakhiwa kwezinhlaka ezahlukene zamapayipi esisi esishisayo naphakathi nendawo, amapayipi amanzi abilayo kanye neshubhu elishisayo le-steam locomotive, ipayipi lentuthu, ipayipi elincane kanye nepayipi lezitini le-arch elinekhwalithi ephezulu. Isakhiwo sekhabhoni Ipayipi lensimbi elishisayo eligoqiwe nelidonswa ngokubanda elingenamthungo.Umehluko phakathi kwamashubhu ensimbi angenamthungo oketshezi kanye namashubhu ensimbi angenamthungo kumabhoyela anengcindezi ephansi naphakathi: Umehluko phakathi kwe-GB/T8163-1999 namashubhu ensimbi angenamthungo wamashubhu ensimbi angenamthungo kanye namabhayela anomfutho ophansi nophakathi Amashubhu ensimbi angenamthungo awuhlobo lwe ithubhu lensimbi elingenamthungo elinengxenye engenalutho ngaphandle kokuzungeza Umcu omude wensimbi.Insimbi inengxenye engenalutho, inqwaba yamapayipi asetshenziselwa ukuthutha uketshezi, njengokulethwa kukawoyela, igesi yemvelo, igesi, amanzi nezinye izinto eziqinile njengamapayipi.Ipayipi elingenamthungo lihlukaniswe ngamashubhu agoqelwe ashisayo, amashubhu agoqelwe ngabandayo, amashubhu adonswa abandayo, amashubhu akhishiwe, ukugqekezwa kwamapayipi.Ipayipi lensimbi elingenamthungo lokudlulisa uketsheziisetshenziselwa ukuthutha amanzi, uwoyela, igesi nolunye uketshezi ngokuvamile olungenamthungo lwepayipi lensimbi.Ipayipi lensimbi engenamthungo eliphansi neliphakathi lisetshenziselwa ukwakhiwa kwezinhlaka ezahlukene zamapayipi esisi esishisayo naphakathi nendawo, amapayipi amanzi abilayo kanye neshubhu elishisayo le-steam locomotive, ipayipi lentuthu, ipayipi elincane kanye nepayipi lezitini le-arch elinekhwalithi ephezulu. Isakhiwo sekhabhoni Ipayipi lensimbi elishisayo eligoqiwe nelidonswa ngokubanda elingenamthungo.
