Ithonya Lendawo Eshisayo Ku-Austenitic Stainless Steel Pipe

Ekhiqizweni lokwelashwa kokushisa, ukuze kucishwe ishubhu lensimbi engagqwali ukuthola yonke i-martensite, ithubhu yensimbi e-austenitic kufanele ipholile ngesilinganiso sokupholisa esilingana noma ngaphezulu kune-V, ukuze ithubhu yensimbi engagqwali i-austenitic nayo ibesezingeni lokushisa ngamakhala . Ngaphambi kokuthi ibole, i-austenite iguqulwa ibe yi-martensite ize ipholile ngaphansi kwephoyinti likaNks. Imvamisa inani eliphansi lokupholisa i-Vk lepayipi lensimbi elingenasici elinamasondo amakhulu libizwa ngokuthi izinga lokupholisa elibucayi.

Ngale ndlela, i-Vk enikezwe ijika le-C lamamaki wensimbi ahlukene iyisisekelo esiyinhloko sokuthola indlela yokuqeda bese ukhetha indlela yokuqeda, kepha ungayithola kanjani i-Vk kusuka kujika le-C? Uma izinga lokupholisa ngesikhathi sokupholisa okuqhubekayo lifakwe phezulu kujika le-C lokupholisa okungajwayelekile, kungukulinganisa kuphela ukunquma i-Vk, ngoba ijika lika-C lokupholisa i-isothermal lihlukile ekuguqulweni kwepayipi le-austenitic lensimbi elingenasici ngesikhathi sokupholisa okuqhubekayo. Okuhlukile (ijika le-c kufanele ligudliselwe kwesokudla ngesikhathi sokupholisa okuqhubekayo). Ngaphezu kwalokho, kudinga ukucatshangelwa lapha ukuthi ngesikhathi sokucima nokupholisa, ukwehla kwezinga lokushisa kuyalingana nesikhathi, khona-ke kukhona ubudlelwane obulandelayo: kepha i-V ebaliwe ihlale iphindwe cishe ama-1.5 amakhulu kune-Vk yangempela elinganisiwe, ngakho ukulungiswa ingezwe kwifomula Nge-coefficient ka-1.5, isilinganiso esibucayi sokupholisa siyatholakala.

Imvamisa kunzima ngokwengeziwe ngobuchwepheshe ukucacisa umdwebo oqhubekayo wokuguqula ukupholisa kunejika le-isothermal C. Ngakho-ke, ijika le-isothermal C lingasetshenziselwa ukulinganisa inqubo yenguquko kanye nemikhiqizo yamapayipi wensimbi engagqwali ngaphansi kwezimo zokupholisa eziqhubekayo.

Le ndlela ukupholisa ishubhu lensimbi engagqwali enobubanzi obuthile obusebenzayo (noma ukujiya) kuma-ejenti ahlukile acimayo, imbondela ijika elipholile elilinganisiwe kujika le-isothermal C, bese ubheka iphoyinti lokuhlangana nejika le-isothermal C ukunquma ngokufanelekile Ukuguqulwa izinga lokushisa nemikhiqizo yale nsimbi enobubanzi obuthile kuma-ejenti ahlukile wokucima kusiqondise ukuthi sakhe inqubo yokupholisa yokwelashwa kokushisa, okuyi-C curve yensimbi engagqwali yensimbi kanye ne-75CrNiMoV steel-deform ekhubazekile yensimbi, futhi ibeka phezulu entshonalanga ku it. Ijika elipholile lobuso nengqikithi yengxenye lapho isampula le-20mm selipholile emafutheni nasemoyeni. Njengoba kukhonjisiwe kuMdwebo 10-18, ipayipi lensimbi elingenalutho elinobukhulu bodonga obungu-20mm lizoba sebangeni lika-650-600 ℃ uma lipholile emoyeni. Zonke izingxenye zangaphakathi ziguqulwa zibe yizicubu ze-pearlite, futhi ubulukhuni bumayelana ne-HRc26 kuphela.

Uma icishiwe emafutheni, ingxenye yale ngxenye izoguqulwa kancane kancane ibe yisakhiwo se-pearlite cishe ngo-590 ℃, futhi inani laso lizobalwa cishe libe ngu-15% ngokuhlaziywa kwe-metallographic, kuyilapho yonke enye ithubhu yensimbi engenazinsimbi engenantambo izoguqulwa esakhiweni se-pearlite esingaphansi kuka-240 ℃. IMartensite, ukuze kutholakale isakhiwo esihlanganisiwe se-martensite (85%) ne-pearlite (15%) ebusweni, ngobulukhuni obucishe bube yi-HRc59. Inhliziyo iguqulwe ngokuphelele ibe izicubu zohlobo lwe-pearlite eziphakathi kuka-660-530 ℃, ngobulukhuni be-HRc37 kuphela. Lokhu kukhombisa ukuthi izinga lokupholisa lomoya no-oyela alizange lenze ithubhu lensimbi engagqwali engu-420 mm ifinyelele ezingeni elibucayi lokupholisa ukucisha. Njengoba i-carbon steel iyinsimbi eqiniswe ngamanzi, noma iyiphi into enezinga lokupholisa elingaphansi kwamanzi nakanjani izothola iphesenti elithile lesakhiwo se-pearlite esakhiweni salo, ngakho-ke alikwazi ukuqedwa ngokuphelele.
