Brass tubyog ib tug nias thiab kos seamless yeeb nkab uas muaj zog thiab corrosion-resistant zog.Cov kav dej tooj dag yog cov kav dej zoo tshaj plaws thiab tau dhau los ua cov kais dej ntawm cov neeg cog lus niaj hnub hauv txhua lub tsev lag luam hauv tsev.Kev xaiv zoo heev rau cov kav dej, cua sov thiab cua txias piping installation.
Cov hauv qab no yog ib qho kev qhia luv luv rau cov txheej txheem ntawm cov raj tooj dag, nrog rau cov kev qhia tshwj xeeb thiab cov khoom siv hluav taws xob ntawm cov raj tooj dag.
Cov txheej txheem ntau lawm ntawm tooj dag raj:
1. Gas tiv thaiv melting thiab kub preservation → kab rov tav nruam casting ntawm tooj liab raj billet → milling kom tshem tawm qhov tsis xws luag → peb-roller planetary dov → on-line coiling rau hauv coils → peb-series sib txuas → disk stretching → straightening, flaw detection, sizing → Ci ntsa iab annealing → packing zoo → packing tiav
2. Upward drawing smelting → upward drawing nruam casting billet → Pilger zeb dov → online annealing coil → peb-series stretching → disc stretching straightening, flaw detection, sizing → muaj zog convection ci annealing → Joint xov → Zoo soj ntsuam → lamination, ntim → tiav cov khoom
3. Melting → (semi-nruab nrab) kab rov tav nruam casting billet → extruding tshuab rau extrude billet → pilger zeb dov → online annealing coil → peb-series stretching → disc stretching straightening, flaw detection, sizing → Muaj zog convective ci annealing → ua tiav cov khoom tiav → coated tiav
Thaum lub sij hawm ua cov yeeb nkab tooj dag, dab tsi yog txoj hauv kev los tiv thaiv kev puas tsuaj ntawm tooj liab yeeb nkab?
Thaum lub sij hawm ua cov tooj liab raj thiab pas nrig, tshwj xeeb tshaj yog high-zinc tooj dag thiab silicon-manganese tooj dag, vim qhov tsis sib xws deformation, kev ntxhov siab sab hauv yuav tsim tawm ntawm lub raj thiab pas nrig.
Qhov muaj nyob hauv kev ntxhov siab yuav ua rau deformation thiab txawm tias tawg ntawm cov ntaub ntawv thaum ua, siv thiab khaws cia.
Txoj kev tiv thaiv yog ua kom muaj kev ntxhov siab sab hauv annealing hauv qab qhov kub ntawm recrystallization hauv lub sijhawm,
Tshwj xeeb tshaj yog rau cov ntaub ntawv alloy uas nkag siab rau kev ntxhov siab hauv lub cev, xws li cov zinc tooj dag, cov kev ntxhov siab sab hauv yuav tsum tau nqa tawm hauv 24 teev tom qab dov lossis ncab.
Internal stress relief annealing feem ntau yog ua los ntawm 250 ° C thiab 350 ° C, thiab lub sijhawm tuaj yeem tsim nyog ntev dua (xws li ntau tshaj 1.5-2.5h).
