Kub Rolled Rina Steel Phaj

Cov txheej txheem txheej txheem thiab kev txheeb xyuas tus nqi ntawm Kub Rolled Rina Steel Phaj

Kub-dov Rina Steel Phaj plays lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam vim nws cov khoom zoo heev thiab kev ua haujlwm zoo. Nkag siab txog cov txheej txheem kev ua haujlwm ntxaws ntxaws uas ua haujlwm hauv nws cov khoom tsim, nrog rau kev txheeb xyuas tus nqi cuam tshuam, yog qhov tseem ceeb rau kev txaus siab rau nws qhov kev ua tau zoo thiab kev siv peev xwm.

Kev tsim cov txheej txheem ntawm Kub Rolled Rina Steel Phaj pib nrog kev xaiv cov khoom zoo raw khoom. Cov no feem ntau suav nrog cov hlau ore, coke, thiab limestone, uas tau ua tib zoo xaiv los xyuas kom meej cov tshuaj muaj pes tsawg leeg ntawm cov khoom hlau kawg. Txawm li cas los xij, tus nqi ntawm cov khoom siv raw tuaj yeem hloov pauv raws li kev ua lag luam thiab qhov zoo thiab muaj cov peev txheej.

Thawj kauj ruam yog txheej txheem hlau. Nyob rau hauv ib lub qhov cub tawg, cov ntaub ntawv raw yog rhuab thiab reacted los tsim molten hlau. Cov hlau molten no ces xa mus rau lub cub tawg steel, qhov twg impurities raug tshem tawm thiab cov muaj pes tsawg leeg raug kho los ntawm kev ntxiv cov ntsiab lus alloying raws li cov cai tshwj xeeb ntawm Rina Steel Phaj. Kev siv hluav taws xob thiab kev saib xyuas cov khoom siv hauv cov theem no ua rau tag nrho cov nqi tsim khoom.

Tom ntej no los ntawm kev nruam casting theem. Lub refined molten hlau yog poured rau hauv ib tug nruam casting tshuab, uas ua rau nws mus rau hauv ntev slabs los yog billets. Cov txheej txheem nruam nruam no ua kom lub microstructure zoo ib yam thiab txo qhov tshwm sim ntawm qhov tsis xws luag. Tus nqi ntawm cov khoom siv nruam nruam, nrog rau cov pwm thiab cov khoom siv coolant, yuav tsum tau muab xam rau hauv.

Cov txheej txheem kub dov yog theem tseem ceeb hauv kev tsim cov Kub Rolled Rina Steel Phaj. Cov slabs los yog billets yog reheated rau qhov kub thiab txias, feem ntau saum lub recrystallization kub ntawm cov hlau. Qhov no reheating ua rau cov hlau ntau malleable thiab yooj yim rau cov duab. Lub zog yuav tsum tau ua kom rov ua dua thiab hnav thiab tsim kua muag ntawm cov dov mills nce tus nqi tsim khoom.
 

Cov khoom siv rhuab yog tom qab ntawd dhau los ntawm cov dov mills. Qhov kev pib dhau los suav nrog roughing mills uas maj mam txo cov thickness ntawm slab los yog billet. Tom qab ntawd, xov mills yog siv los ua kom tiav qhov kawg xav tau thickness thiab meej qhov ntev ntawm cov phaj steel. Tus nqi ntawm cov dov mills, hloov cov yob, thiab cov neeg ua haujlwm koom nrog txhua tus pab txhawb rau tag nrho cov nuj nqis.

Thaum lub sij hawm kub dov txheej txheem, kev tswj cov tsis xws li dov kub, dov ceev, thiab txo qhov piv ntawm qhov tseem ceeb tshaj plaws. Cov kev ntsuas no ncaj qha cuam tshuam rau microstructure thiab mechanical zog ntawm steel phaj. Qhov kub dov ntau dua tuaj yeem txhim kho lub formability ntawm cov hlau, tab sis nws yuav tsum tau tswj nyob rau hauv ib tug tsim nyog ntau yam kom tsis txhob overheating thiab detrimental los ntawm cov khoom. Kev ua tiav thiab kev tswj xyuas cov kev pom zoo no yuav tsum muaj kev tswj hwm qib siab thiab cov neeg ua haujlwm txawj, ntxiv rau tus nqi.

Tom qab kub dov, lub phaj hlau yuav dhau los ua cov kauj ruam ntxiv txhawm rau txhim kho nws cov khoom. Ib kauj ruam uas nquag yog tswj kom txias. Los ntawm kev tswj xyuas qhov txias txias, qhov microstructure ntawm cov hlau tuaj yeem ua kom zoo dua qub, ua rau cov khoom siv kho kom zoo dua qub xws li lub zog thiab tawv. Tus nqi ntawm cov khoom siv cua txias thiab lub zog siv rau kev ua kom txias yuav tsum tau txiav txim siab.

Kev kho cua sov kuj tseem yuav ua haujlwm nyob ntawm qhov tshwj xeeb ntawm daim ntawv thov. Annealing, normalizing, los yog quenching thiab tempering yuav siv tau los hloov lub microstructure thiab ua tiav qhov xav tau sib npaug ntawm hardness, lub zog, thiab ductility. Tus nqi ntawm kev kho cua sov rau cov cua sov, cov roj cua lossis cov khoom siv siv, thiab lub sijhawm thiab lub zog siv thaum lub sijhawm ua haujlwm no ua rau tag nrho cov nqi.

Kev kho saum npoo yog lwm qhov tseem ceeb. Cov hlau phaj tuaj yeem ua tiav cov txheej txheem xws li descaling kom tshem tawm cov txheej txheem oxide thiab txhim kho qhov chaw tiav. Qhov no pab txhim kho cov tsos thiab corrosion kuj ntawm lub phaj. Tus nqi ntawm cov tshuaj kho deg, khoom siv, thiab kev ua haujlwm yuav tsum suav nrog.

Thoob plaws hauv tag nrho cov txheej txheem, kev tswj xyuas kev ua tau zoo yog siv rau txhua theem. Cov kev kuaj tsis yog kev puas tsuaj xws li kev kuaj ultrasonic thiab kev tshuaj xyuas cov khoom sib nqus yog siv los kuaj xyuas cov teeb meem sab hauv lossis qhov chaw. Kev kuaj thiab kev ntsuas tshuab kuj tseem ua tiav los xyuas kom meej tias cov phaj hlau ua tau raws li cov qauv nruj thiab cov lus qhia tshwj xeeb tau teeb tsa los ntawm Rina (Registro Italiano Navale). Tus nqi ntawm cov txheej txheem kuaj thiab tshuaj xyuas no, nrog rau cov khoom siv thiab cov neeg ua haujlwm koom nrog, yog ib feem tseem ceeb ntawm cov qauv nqi tag nrho.

Hauv kev xaus, kev tsim khoom ntawm Kub Rolled Rina Steel Phaj cuam tshuam nrog cov txheej txheem ua tiav thiab meej. Kev tswj xyuas kom zoo ntawm txhua kauj ruam, los ntawm kev xaiv cov khoom siv raw mus rau qhov kawg kev kho mob, xyuas kom meej tias cov phaj steel muaj cov khoom xav tau thiab zoo. Cov nqi cuam tshuam, suav nrog cov khoom siv raw, kev siv hluav taws xob, khoom siv, kev ua haujlwm, thiab kev tswj kom zoo, txhua yam yuav tsum tau soj ntsuam thiab tswj xyuas kom muaj kev lag luam zoo thiab kev sib tw ntawm cov khoom lag luam. Kev tshawb fawb tsis tu ncua thiab thev naus laus zis hauv kev ua haujlwm txuas ntxiv txhim kho cov txheej txheem kev ua haujlwm thiab cov nqi ua haujlwm tau zoo, ua rau muaj txiaj ntsig zoo dua Kub Rolled Rina Steel Phaj.
