Q: Dab tsi ua cov txheej txheem tsim nyog rau SPCC?
A: Stamping, dabtsi yog khoov, ncab, shearing, vuam; S- xeev yog haum rau kev sib sib zog nqus nqus, semi- nyuaj / nyuaj yog haum rau yooj yim khoov thiab shaping.
Q: Yuav ua li cas los daws qhov teeb meem ntawm lub caij nplooj ntoos hlav ntau dhau thaum SPCC dabtsi yog khoov (xws li, 90℃txog 85℃-95 degree)?
A: ① Khoom siv: Xaiv S- xeev lossis ua ntej-annealed; ② txheej txheem: V-groove dav 6–8t, dabtsi yog khoov vojvoog Ntau tshaj los yog sib npaug rau 1t, ceev Tsawg tshaj los yog sib npaug rau 10mm/s; ③ Tuag: Nce blanking quab yuam los yog them rau lub kaum sab xis (+1℃-+3℃).
Q: Dab tsi yog qhov ua rau thiab kev tawm tsam rau SPCC tensile cracking?
A: Ua rau: Cov khoom siv hardness siab dhau lawm, kos qhov sib piv loj dhau, lubrication tsis txaus, tuag vojvoog me me dhau; Countermeasures: Hloov mus rau S-state, optimize tuag vojvoog, siv cov roj kos duab, thiab ua cov kauj ruam-los ntawm- kauj ruam kos duab.
Q: Cov txheej txheem vuam thiab kev ceev faj rau SPCC yog dab tsi? A: Txhawb nqa arc vuam, tiv thaiv vuam, thiab roj vuam; qis- carbon, yooj yim rau vuam; post-weld slag tshem tawm thiab tiv thaiv xeb (txhaj tshuaj / galvanizing) kom tsis txhob muaj hydrogen embrittlement.
Q: Yuav ua li cas degrease ua ntej SPCC nto kho? A: Siv cov alkaline degreaser + ultrasonic tu, ua raws li cov dej yaug thiab ziab, kom ntseeg tau tias Ra tsawg dua lossis sib npaug li 0.8μm los lav txheej / plating adhesion.
