Cov khoom siv tonnage dab tsi xav tau rau stamping SPCD yob?
A: Nws nyob ntawm qhov loj thiab deformation ntawm qhov chaw stamped. Rau cov khoom me me, cov khoom siv stamped, ib lub tshuab 50-100 tuj yog txaus. Rau loj, complex stamped qhov chaw xws li tsheb chassis, ib tug 200-500 tuj loj stamping tshuab yog yuav tsum tau los xyuas kom meej tsim zoo.
Cov kev hloov pauv dab tsi tshwm sim hauv cov khoom ntawm SPCD yob tom qab annealing?
A: Annealing kiag li tshem tawm cov kev ntxhov siab sab hauv, txo cov hardness thiab yield zog, thiab txhim kho plasticity thiab toughness. Nws txhim kho lub peev xwm deformation thaum lub sij hawm stamping, zoo txo cov teeb meem xws li cracking thiab springback.
Cov ntsuas dab tsi yuav tsum tau tsom mus rau thaum lub sijhawm tshuaj ntsuam SPCD yob?
A: Cov cim tseem ceeb los tshuaj xyuas yog cov tshuaj muaj pes tsawg leeg, qhov zoo ntawm qhov chaw (tsis muaj khawb, pitting, lossis lwm yam tsis xws luag), thickness kam rau ua, txhua yam khoom (yield zog, tensile zog), thiab dabtsi yog khoov kev ua tau zoo. Cov ntsuas no ncaj qha cuam tshuam rau kev ua tau zoo thiab cov khoom tiav tiav.
Dab tsi ua rau hauv zos siab hardness hauv SPCD yob?
A: Qhov no feem ntau yog vim cov txheej txheem annealing tsis txaus, xws li tsis txaus annealing kub lossis tuav lub sijhawm, ua rau tsis tiav ntawm kev ua haujlwm nyuaj hauv qee qhov chaw. Nws kuj tseem tuaj yeem tshwm sim los ntawm qhov tsis sib xws ntawm lub zog dov thaum lub caij txias dov, ua rau tsis sib xws hardness faib.
Yuav ua li cas lwm txoj kev galvanizing tuaj yeem txhim kho corrosion kuj ntawm SPCD coils?
A: Electroplating nrog npib tsib xee, txau nrog cov tshuaj tiv thaiv -corrosion txheej, thiab lwm yam, tuaj yeem siv. Kev kho mob Passivation kuj tseem tuaj yeem ua rau tsim cov oxide zaj duab xis ntom ntom ntawm qhov chaw. Rau luv luv- siv lub sij hawm, kev tiv thaiv corrosion yooj yim tuaj yeem ua tiav los ntawm kev siv xeb- cov xim tiv thaiv.
