Q: Dab tsi yog qhov tsis xws luag thiab ua rau SPCC coils?
A: Kos: Yob puas / taw qhia khawb → Tshawb xyuas cov khoom siv, ua kom zoo dua ntim
Oxidation xim: Tsis zoo annealing cua → Kho H₂ / N₂ ratio
Ntug waviness / Nruab nrab waviness: Tsis sib luag dov quab yuam → Fine -tune leveling zeb yob qhov sib txawv
Inclusions: Tsis txaus steelmaking huv si → Txhim kho LF refining thiab nruam casting tiv thaiv slag zoo
Q: Yuav ua li cas txiav txim siab qhov zoo ntawm SPCC?
A: Raws li JIS G3141: Qib A: Tsis pom qhov tsis xws luag; Qib B: Me me khawb / indentations raug tso cai, tsis cuam tshuam rau kev tsim.
Q: Dab tsi yog qhov ua rau thiab tuav ntawm thickness kam rau ua deviations?
A: Ua rau: Yob hnav / AGC hloov pauv; Kev tuav: Hloov cov yob, calibrate AGC, downgrade coils nrog deviations los yog xa raws li kev pom zoo.
Q: Yuav ua li cas los daws qhov teeb meem ntawm daim ntawv (xws li camber)?
A: Kho coiling nro, zoo -tune leveling zeb ua hauj lwm yob dabtsi yog khoov/hloov, thiab nyob rau hauv mob hnyav, luas ntug los yog slit.
Q: Dab tsi ua rau xeb pob ntawm SPCC coils?
A: Insufficient oiling/ineffective rust-preventive oil, storage humidity >60%, kev ntim khoom puas ua rau dej nkag; Kev Tiv Thaiv: Siv VCI xeb- tiv thaiv zaj duab xis, noo noo{2}} pov thawj ntsaws rau lub kauj, thiab tswj cov av noo ntawm 40-60%.
