Indlela yokukhiqiza nenqubo yebha yensimbi evuthayo evuthayo
Icebo langemuva:
Emakethe yamanje yokubuyiselwa emuva, ama-HRB400E ama-akhawunti okuthe xaxa. Indlela ye-Microalloly Exgening iyindlela esemqoka yokukhiqiza i-HRB400E emhlabeni. IMicroalloy ikakhulukazi ye-Aloy noma i-Niobium Alloy, edla izinsiza eziningi ze-alloy njalo ngonyaka. Ngenxa yezinsizakusebenza zamaminerali ezinomkhawulo eziqukethe i-vanadium ne-niobium, ukunikezwa kwalezi zinto ezenziwayo ziqinile. Ngakho-ke, uma okuqukethwe kwe-alloy yebha yensimbi ye-HRB400E kungancishiswa, kuzokhiqiza izinzuzo ezinkulu zezomnotho nezenhlalo.
In the existing technology, the double-wire rolling production line without reducing and sizing rolling mill generally adopts vanadium alloy strengthening to produce hrb400e, and the mass percentage content of vanadium is 0.035% to 0.045%.
I-Chinese Patent CN10435774a yembula uhlobo lwe-HRB400E anamandla okuzamazama komhlaba okuvimbela ukuzamazama komhlaba kanye nendlela yalo yokukhiqiza. Ngale ndlela, umkhiqizo ophelile ukhiqizwa ngokunciphisa futhi usayizi wokugoqa, ongaqinisekisa ukuthi insimbi esongwe esongelwe igingqika emazingeni okushisa aphansi ka-730 ~ 760 ℃ ukuthola imigqa yokukhiqiza ngaphandle kokunciphisa ama-ming. I-Chinese Patent CN110184516A yembula indlela yokulungiselela ye-wire ephezulu Φ6MM ~ HRB400E Screw Screw. Ngosizo lomthamo oqinile wokuqalisa kwemishini, ukugibela okushisa okuphansi kuqala kusuka ekushiseni kokufudumeza, kanye nokukhiqizwa ngaphandle kwe-microallooling kuyabonakala. Ukungathandeki kwale ndlela ukuthi izidingo zamandla kanye nokusebenza kwezimoto zemishini yokugoqa okunzima nokuphakathi kuphakeme kakhulu, ikakhulukazi ngomugqa wokukhiqiza we-Torsion Rolling, okunciphisa izindleko zokuhlola ze Imishini, kanye namandla okuvuselela ocingo oluphezulu Φ6mm ~ HRB400E coil ekhiqizwe yile ndlela yile ndlela eyengeziwe. Inani elinganele, kunzima ukuqinisekisa izinga lokusebenza kweziqu.
Izinto Zokusetshenziswa Kwezobuchwepheshe:
Ukusungulwa kwamanje kuhlose ukuhlinzeka ngendlela yokukhiqiza imigoqo yensimbi eshisiwe evulekile, ikakhulukazi indlela yokukhiqiza iminenke ekhokhelwa evulekile ye-wire ephezulu ye-φ8 φ10mm ~ hrb400e, onqoba ukushiyeka okushiwo ngenhla kobuciko odlule futhi anciphise ukukhiqizwa izindleko.
Isikimu sobuchwepheshe sokusungulwa kwamanje:
Indlela yokukhiqiza yebha yensimbi evuthayo evuthayo, ukucaciswa kwentonga yensimbi yensimbi eboshwe ngu-φ8 Φ 100Mm, kanye nenqubo yokugoqa - Ukupholisa - Ukupholisa - Ukupholisa - Ukuqeda - Ukuqeda - Ukupholisa - Ukuxubha - Ithebula le-Roller Table epholile Amaphesenti amakhemikhali akwakhemikhali ensimbi yi-C = 0.20% ~ 0.25%, si = 0.40% ~ 1.60%, i-P≤0% ~ 1.60%, i-P≤0.045%, v.015% ~ 0.020% ~ 0.020%, ezinye izinto zokunye ukungcola nezingenakugwenywa; Izinyathelo ezibalulekile zezinqubo zifaka: Ukushisa kwe-Uthando kungu-1070 ~ 1130 ~ 1130 ℃, izinga lokushisa le-Trealing Rolling lingu-970 ~ 1000 880 ℃; Ukushisa izinga lokushisa 845 ~ 875 ℃; Izinga lokushisa lokugcina lingaphansi kokushisa kabusha kokushisa kwendawo ye-Autenite; ukupholisa okusheshayo ngu fan etafuleni le-roller epholile emoyeni, ivolumu yomoya ingu-100%; Izinga lokushisa lesembozo lingu-640 ~ 660 ℃, izinga lokushisa lesembozo sokulondolozwa kokushisa lingu-600 ~ 620 ℃, nesikhathi esembozweni sokulondolozwa kokushisa ngu-45 ~ 55s.
Umgomo wokusungulwa: Ngobubanzi bezinga lokushisa 840-880 ℃, okusanhlamvu kwe-Auucenite kudluliselwe yi-rolling deformation, kepha ukucekelwa phansi kabusha akwenzeki. Kodwa-ke, amaqembu we-defformation akhiqizwa okusanhlamvu kwe-aucenite, futhi ukuphela kwamaqembu okuba yimikhawulo ngokuvamile kunemingcele yokusanhlamvu, futhi kukhona amabhendi okonakala ezindaweni ezisanhlamvu njengemingcele ebonakalayo yokuhlukanisa okusanhlamvu okugcwele ama-aucenite. Ngesikhathi sokuguqulwa kusuka ku-Aucen kuya ku-Ferrite, womabili imingcele yokusanhlamvu ephakeme ye-Aunten kanye ne-fatary ebonakalayo defformary zone zone njengezindawo ze-ncleaty ze-Ferrite, okuholela ekucongweni kweFerrite ngemuva kwenguquko. Ukugeleza kwamazinga okushisa okuphansi endaweni yokuqeda kunciphisa umthwalo wokugoqa we-routing and intermiate rolling mill
Imiphumela ezuzisayo yokusungulwa imi ngalendlela elandelayo: Ngokungeza inani elincane le-V for Microllol Ukuqinisa, Amandla Ovuthiwe athuthukiswa, v kanye c form carbides, bese uthatha indima yokuqina kwemvula ngemuva kokugoqa . Induku yocingo evuthayo yokusungulwa inamandla ashukumisayo angama-600-700MPA, amandla okuvutha angu-420-500MPA, amandla aphakathi anezithelo ezingaba ngu-450mpa, kanye ne-10%, eqinisekisa imajini eyanele. Amandla wesivuno aqinile, futhi izinga lokusebenza kweziqu zemfundo lingaphezulu kwama-99%. Ukusungulwa ngobuchwepheshe okuxazulula inkinga ukuthi i-Twist Rolling Mill kunzima ukwenza ukugingqa amazinga okushisa aphansi, kunciphisa izindleko esisesimweni sokuqinisekisa ukuthi umthamo wokukhiqiza awuncishisiwe, futhi ulethe izinzuzo zezomnotho eziphakeme.
Izindlela Ezinemininingwane
Okuqukethwe kokusungulwa okukhona kuchazwe ngokwengeziwe ngokuhlangana nama-embodiments.
Indlela yokukhiqiza yeqembu le-wire ephezulu φ8mm ~ φ10Mmhrb400e iminenke ehlanganisiwe. Inqubo yokugoqa ukuthi: Ukushisa okuphumayo Ukushisa ngo-640 ~ 660 ℃, 600 ~ 620 ℃ ukuphuma kwesembozo sokulondolozwa kokushisa, isikhathi lapho isembozo sokulondolozwa kokushisa singu-45 ~ 55s, futhi siphola ngokwemvelo. Ukwakheka kwamakhemikhali kwenduku yocingo ye-Embodiment of the ukusungulwa kwamanje kuboniswa kuThebula 1, kanye nezici zemishini zenduku yocingo yokusungulwa okukhona manje kukhonjiswe kuThebula 2.
Ukwakheka kwamakhemikhali (i-WT%) yenduku yocingo yesibonelo sethebula
Ithebula 2 Izakhiwo Zomshini Wezibonelo Zocingo
Amandla othelani ocingo oluphezulu φ8mm ~ Φ 100Mmhrb400e iminenke ehlanganisiwe ekhiqizwa yindlela yokusungulwa isezingeni le-420 ~ 500MPA, isilinganiso se-Agx singenhla kwe-10%, futhi isakhiwo se-metallographic ikakhulukazi kanye ne-pearlite. , Ukusebenza okuzinzile, amandla anele okuvuna kanye ne-agst margin, impumelelo yale nqubo ibaluleke kakhulu ekunciphiseni izindleko zokukhiqiza kanye nenzuzo eyandayo yemizila emidala ekhulayo.
Izici Zobuchwepheshe:
1. Indlela yokukhiqiza yebha yensimbi evuthayo eshisayo, ukucaciswa kwe-wire rod yi-φ8mm ~ Φ 100Mm, kanye nenqubo evulekile - Ukupholisa okuphakathi - Ukupholisa - Ukuqeda - Ukuqeda - Ukupholisa - Ukupholisa - Ukuqoqa i-Coil-Slow Cool-slow ehamba kancane, kubonakaliswa kulokho: Amaphesenti amancane wamakhemikhali e-Steel ngu-C = 0.20% ~ 0.25%, i-MN = 1.60% ~ 1.60%, p≤ I-0.045%, S≤0.045%, v = 0.015% ~ 0.020%, ezinye izinto zokungcola ezingenakugwenywa; Izinyathelo ezibalulekile zenqubo zifaka: Ukushaya okuthephayo kungu-1070 ~ 1130 ° C, izinga lokushisa langaphambi kokuqedwa lingama-970 ~ 1000 ° C, futhi ukuqedwa kokuqeda kwenziwa. Izinga lokushisa lingu-840 ~ 880 ℃; Izinga lokushisa lokujikeleza lingu-845 ~ 875 ℃; Amazinga okushisa okugcina angaphansi kokushisa okuphindaphindiwe kwendawo ye-Audenite; Iphoqelelwa ngokushesha ngumlandeli etafuleni le-roller epholile emoyeni, futhi ivolumu yomoya ingu-100%; Ithebula le-roller lifakwa ngokuvala isembozo sokufakelwa, izinga lokushisa lokufaka isembozo sokufakelwa lingu-640 ~ 660 ℃, futhi izinga lokushisa lokukhipha isembozo sokufakelwa ngu-600 ~ 620 ℃, nesikhathi esisembozweni sokufakelwa ngu-45 ~ 55s.
Isifinyezo sobuchwepheshe
Indlela yokukhiqiza yebha yensimbi evuthayo evuthayo, intwasahlobo yensimbi evuthayo yocingo eshisayo yi-φ8mm ~ φ10mm, okuqukethwe kwamaphesenti amakhemikhali okuqukethwe kwensimbi kungu-C = 0.25% ~ 0.50% , Mn = 1.40% ~ 1.60%, P≤0.045%, S≤0.045%, v = 0.015% ~ 0.020% izinto ezingcolile ze-FE nengenakugwenywa; Inqubo yokugoqa yile: Ukushisa kothando kungu-1070 ~ 1130 ℃, nokuqedwa kwangaphambi kwenziwa.
