Yiziphi ububanzi bezinto ezibonakalayo ezingasongwa yi-Multi Stand Reducing Rolling Mill

        II-I-I-Multi Stand Reducing Rolling Milliyimishini ebalulekile emigqeni yokuqeda ipayipi lensimbi engenamthungo. Ngokuqhubekayo yehlisa ububanzi bangaphandle bamashubhu abhoboziwe ashisayo noma akhishwe ngaphandle ngezitendi eziningi eziginqikayo ngaphansi kwengcindezi elawulwayo. Enye inzuzo enkulu yale mishini ilele ekuguquguqukeni kwayo nezimo kuzinto ezihlukahlukene zensimbi. Ngokulungisa izinga lokushisa eliginqikayo, ukushuba kwesimo, ukuklanywa kokudlula kanye nezinto ezigoqayo, umshini wokugaya ungacubungula i-spectrum ebanzi yamabanga ensimbi nezinto ze-alloy zokusetshenziswa kwamapayipi embonini ahlukene.

I-Material Range ye-I-I-Multi Stand Reducing Rolling Mill

1. Insimbi Yekhabhoni

       I-Carbon steel iyinto evame ukucutshungulwa ezigayweni zokunciphisa izitendi eziningi.

       Insimbi ye-carbon ephansi: I-ductility eshisayo enhle kakhulu, ukusebenza okuzinzile kwe-rolling. Isetshenziselwa kakhulu amapayipi okulethwa kwamanzi, amashubhu ensimbi esakhiwo, amapayipi emishini ejwayelekile.

       I-Medium carbon steel: Idinga ukulawulwa kwezinga lokushisa okuqinile ngesikhathi sokuginqika. Kusetshenziswa ezingxenyeni zemishini, izingxenye zepayipi lokucindezela.

       Insimbi ye-carbon ephezulu: Ukumelana nokuguquguquka okuphezulu. Kudingeka ukulawulwa okuqinile kokuqina kanye nokugcotshwa okuhle ukuze ugweme ukonakala kwendawo. Ifanele amashubhu emishini ekhethekile.

2. Insimbi Ephansi Yengxubevange

       Insimbi ye-alloy ephansi yengeza amanani amancane ezinto ezihlanganisiwe ukuze kuthuthukiswe amandla, ukuqina kwezinga lokushisa eliphansi kanye nokumelana nokugqwala. Amabanga ajwayelekile afaka uchungechunge lwe-Cr-Mo, insimbi ye-Mn-V.

       Lezi zinto zisetshenziswa kabanzi kumapayipi obhayela, emikhunjini yokucindezela, amapayipi okuthutha uwoyela negesi. Ngesikhathi sokugingqika, umshini wokugaya kufanele ulawule ukufana kokushisisa kanye nokushuba kwesimo ukuze kuvinjelwe ukungalingani kodonga kanye nokuqhekeka kwendawo.

3. I-alloy Steel (Ingxubevange Emaphakathi & Ephakeme)

       Insimbi ye-alloy emaphakathi nephezulu ifaka ukumelana nokushisa okuphezulu kwe-thermal.

       Izinto ezijwayelekile: insimbi ye-chrome alloy, insimbi ye-nickel-chromium alloy.

       Amukelwa amapayipi esevisi asezingeni eliphezulu, amashubhu okushintsha ukushisa kanye namapayipi e-petrochemical. Amapharamitha okugoqa kufanele alungiselelwe ngokucophelela, okuhlanganisa izinga lokushisa eliqala ukugoqa, ukuncishiswa kwephasi ngayinye kanye neshejuli yokupholisa. Ukungezwani okungafanele kuzodala kalula ukulimala kwepholigoni yangaphakathi kanye nokuchezuka kodonga.

4. Insimbi Engagqwali

       Insimbi engagqwali ye-Austenitic iyibanga elivamile elicutshungulwa izigayo zokunciphisa i-multi-stand. Inezici eziqinile zokuqinisa umsebenzi futhi idinga umklamo okhethekile wokudlula nokulawula izinga lokushisa.

       Isetshenziselwa amapayipi embonini yokudla, amapayipi ahambisa uketshezi lwamakhemikhali, amashubhu okushintshanisa ukushisa.

       Qaphela: Insimbi engagqwali inokumelana nokuguga okushisayo okuphezulu. Ukuncishiswa kwesitendi esisodwa ngokweqile kungase kubangele imihuzuko, ukuklebhuka kwendawo kanye nokuqina kodonga olungalingani.

5. Ama-alloys akhethekile (Ukucushwa ongakukhetha kuyadingeka)

Ngemiqulu eyenziwe ngokwezifiso, idizayini yokudlula kanye nenqubo yokushisa, umshini wokunciphisa izitendi eziningi ungagingqa amanye amashubhu alloy akhethekile:

       Ama-alloys e-Ferritic ukumelana nokushisa

       Amashubhu e-Titanium alloy (idinga ukuguqulwa kwemishini ezinikele kanye nokulawulwa okuqinile kwenqubo)

       Amashubhu e-Copper alloy (izinga lokushisa elikhethekile lokugoqa kanye nesu lokushuba)

       Isikhumbuzi: Ama-alloys akhethekile ngokuvamile adinga izinto ezigoqayo ezenziwe ngokwezifiso, isimo sokuzivikela kanye namapharamitha okucubungula, futhi awatholakali ekucushweni okujwayelekile komshini.

Izinto Ezibalulekile Ezithinta Ukuguquguquka Kwezinto Ezikuwo

       I-Hot ductility: Izinto ezinokushisa okungekuhle zinamafasitela amancane okushisa, kulula ukukhiqiza imifantu.

       Ukumelana ne-Deformation: Okuqukethwe kwe-alloy ephakeme kuletha isidingo esiphezulu samandla, okubeka izidingo eziphakeme ekuqineni kwesitendi namandla okushayela.

       Ukuzwela ku-tension: Ezinye izinto ze-alloy zizwela ukushintshashintsha kwe-tension. Ukungezwani okungafanele kubangela ukuchezuka kokuqina kodonga kanye nepholigoni yangaphakathi.

       Izici zokupholisa: Izinto ezihlukile zidinga isilawuli sokupholisa esihlukile ngemva kokuginqika ukuze kuqinisekiswe izakhiwo zokugcina zokulungisa.

Isifinyezo

       II-I-I-Multi Stand Reducing Rolling Millingagingqa iphothifoliyo yempahla ebanzi isuka ku-carbon steel evamile, insimbi ye-alloy ephansi, insimbi ephezulu yengxubevange iye ensimbini ye-austenitic. Kumapayipi akhethekile e-alloy afana nama-titanium alloys, isigayo sidinga ukwenziwa ngokwezifiso kwamaroli, amandla kanye nezinqubo zokugingqika. Lapho kukhethwa okokusebenza okuginqikayo, abasebenzisi kufanele baqinisekise ibanga lempahla, ukucaciswa kwepayipi nezimfuneko zokusebenza nomkhiqizi ukuze afane nenqubo efanele yokumisa umshini kanye nenqubo yokugingqika.
