Dab tsi yuav tsum tau them nyiaj rau hauv cov txheej txheem ntau lawm ntawm seamless stainless hlau kav?
Daim ntawv thov ntawm seamless stainless hlau kav yog tam sim no nyob rau hauv lub khw loj heev. Tseem muaj ntau cov ntsiab lus uas peb yuav tsum tau txawj hais txog nws cov thev naus laus zis ua. Daim ntawv thov ntawm seamless stainless hlau kav yuav tsum tau ntxig kom meej rau peb. Cia peb tham txog dab tsi yuav tsum tau them nyiaj rau hauv kev siv cov tshuab ntawm kev ua se ntawm cov kav hlau stainless hlau?
1. Txias-kos (dov) seamless steel yeeb nkab:
Cov khaub thuas txias ntawm cov khaub ncaws txias-kos (dov) seamless steel yeeb nkab muaj ntau ntau dua li kub-dov (extruded seamless steel yeeb nkab). Thawj peb kauj ruam ntawm lawv cov txheej txheem ntau lawm yog ib qho zoo ib yam. Qhov sib txawv pib los ntawm plaub txheej txheem. Tom qab lub raj hloov root billet yog hollowed tawm, nws yuav tsum qhib thiab quenched. Tom qab quenching, nws yuav tsum tau pickled thiab passivated nrog cov kua acidic tshwj xeeb. Tom qab pickling thiab passivation, roj tau thov. Tom qab ntawd nws yog ua los ntawm kev sib nqus ntau (colding txias) thiab tom qab ntawd billet raj, ib txheej txheem kev kho cua sov tshwj xeeb. Tom qab cov txheej txheem kho cua sov, nws yuav tsum ncaj.
2. Kub Rolling (extruded seamless steel yeeb nkab):
Cov khoom siv raw ntawm cov hlau txias-dov seamless steel yeeb nkab rau hauv ib lub raj mis txiav rau hauv lub raj mis tsis siv neeg thiab xa mus rau lub cub tawg kom cua sov kom muaj cua conveyor. Lub billet xa mus rau lub rauv melting rau cua sov, thiab qhov kub thiab txias yog li 1200 degree. Lub zog hluav taws xob yog nitrogen lossis acetylene roj. Kev tswj qhov kub thiab txias nyob rau hauv lub cub tawg yog qhov mob tseem ceeb. Tom qab lub raj hloov roo billet tso tawm, nws yuav tsum tau nkaug los ntawm lub tshuab siab tho. Feem ntau, cov tshuab tho ntau dua yog lub consical cov menyuam cov menyuam txais tshuab. Hom phiaj ntawm no muaj kev ua haujlwm siab, cov khoom lag luam zoo, loj lub qhov loj nthuav dav, thiab tuaj yeem siv rau ntau yam ntawm cov qauv steel. Tom qab tho kev, lub raj hloov lub raj billet tau txais kev vam meej los ntawm peb chais, kub dov lossis extruded. Tom qab extrusion, nws yuav tsum tau muab tshem tawm ntawm lub raj thiab qhov loj me. Lub tshuab sizing siv lub conical twist laum khiav ntawm qhov kev kub ceev rau hauv cov hlau billet kom ib lub qhov chaws los ua cov yeeb nkab steel. Cov kabinal ntawm cov hlau yeeb yog txiav txim siab los ntawm txoj kab uas hla ntawm lub tshuab sizing. Tom qab cov yeeb nkab steel yog qhov loj me, nws nkag mus rau hauv cov frp txias ntauwd thiab yog txias los ntawm dej txau. Tom qab txias, cov yeeb nkab steel yuav tsum yog ncaj. Tom qab sab nraud ncaj, cov yeeb nkab steel xa mus rau cov khoom siv hlau hluav taws xob x-ray tshuab (lossis ntsuas siab) los ntawm tus qauv sab hauv qhov pom kom pom. Yog tias muaj cov kab nrib pleb, me me npuas thiab lwm yam teeb meem hauv cov qauv sab hauv ntawm cov yeeb nkab steel, lawv yuav raug kuaj pom. Tom qab kev tshuaj xyuas zoo ntawm cov yeeb nkab steel, nws kuj yuav tsum tau xaiv nruj me ntsis los ntawm kev sib ntau ntawm kev sib txua.
