Carbon Steel Seamless Tus Hlau Tube - Royal pawg

1. Kub Rolling (Extrusion Seamless Steel Yeeb Nkab (Nrov siv hluav taws xob → Cia
Cov khoom siv raw ntawm dov seamless lub raj yog puag ncig lub raj billet, thiab ua rau lub raj hluav taws xob ntawm txog 1 me nyuam yaus tsis yog txiav Lub billet yog pub rau hauv lub cub tawg thiab ua kom sov li ntawm 1200 degrees Celsius. Cov roj yog hydrogen lossis acetylene. Qhov kub tswj tau nyob rau hauv lub cub tawg yog qhov teeb meem tseem ceeb. Tom qab puag ncig raj billet los, nws yog perforated los ntawm lub siab xuas nrig ntaus. Feem ntau, feem ntau cov perforator yog lub conical yob perforator. Qhov no perforator muaj kev ua haujlwm siab, cov khoom lag luam zoo, loj perforating diam thiab tuaj yeem hnav ntau cov hlau. Tom qab perforation, lub raj puag ncig lub raj billet tau txais txiaj ntsig zoo los ntawm peb kab pheeb ces kaum, tsis tu ncua yob lossis extrusion. Tom qab extrusion, cov yeeb nkab yuav tsum tau muab tshem tawm rau sizing. Lub caliper rotates rau hauv tus hlau embryo los ntawm kev sib tham laum ntawm kev kub ceev rau punch qhov thiab daim ntawv hlau kav hlau. Lub innera sab hauv ntawm cov yeeb nkab steel yog txiav txim siab los ntawm cov kab uas hla ntev ntev ntawm lub caliper laum me ntsis. Tom qab sizing cov yeeb nkab steel, nws nkag mus rau ntauwd txias thiab txias los ntawm txau dej. Tom qab txias cov yeeb nkab steel, nws yuav ncaj.
2. Txias-kos (dov) seamless steel yeeb nkab: cleuping → cua txias → Kev kho cua sov → Kev kho cua sov → Kev kho kom sov → Hydrostatic Kuaj (Kev Soj Ntsuam) → khij → cia.
Cov txheej txheem dov ntawm cov khaub thuas txias (dov) seamless steel yeeb nkab muaj ntau nyuaj tshaj li ntawm kub dov (extrusion) seamless steel yeeb nkab. Thawj peb kauj ruam ntawm lawv cov txheej txheem ntau lawm yog ib qho zoo ib yam. Qhov sib txawv ntawm cov kauj ruam thib plaub, hloov lub raj dawb tom qab xuas nrig ntaus, mus rau lub taub hau, annealing. Tom qab annealing, tshwj xeeb kua qaub yog siv rau pickling. Tom qab pickling, roj yog thov. Qhov no yog ua raws los ntawm kev kho cua sov tshwj xeeb ntawm cov raj rebillet tom qab ntau qhov txias txias (txias dov). Tom qab kev kho cua sov, nws yog ncaj.
