Q: Dab tsi yog cov qauv kev ua haujlwm txias txias rau Q235 coils?
A: Raws li GB / T 232, tsis muaj qhov tawg yuav tsum tshwm sim tom qab 180℃txias dabtsi yog khoov kuaj; lub mandrel txoj kab uas hla d=1.5a (a yog cov qauv tuab), kho raws li cov qauv khoom.
Q: Dab tsi yog qhov hardness ntau ntawm Q235 coils?
A: Kub- dov HB 100–140, tsis muaj tus qauv tsim nyog, rau kev siv nkaus xwb, tsis yog rau kev lees paub.
Q: Dab tsi yog cov txheej txheem tsim khoom rau Q235 kub -rolled coils?
A: Blast furnace ironmaking → converter steelmaking → LF / VD refining → nruam casting billet → cua sov rauv → ntxhib dov → tiav dov → laminar ntws txias → coiling → soj ntsuam → warehousing.
Q: Dab tsi yog qhov cuam tshuam ntawm coiling kub ntawm cov khoom ntawm Q235 coils?
A: Coiling kub 550-650 degree; Qhov kub qis dhau tuaj yeem ua rau muaj zog dua thiab qis dua plasticity; Qhov kub thiab txias dhau heev tuaj yeem ua rau cov qauv banded, cuam tshuam rau kev ua haujlwm txias thiab vuam.
Q: Dab tsi yog daim ntawv thov tseem ceeb ntawm Q235 coils? A: Cov vaj tse (steel structures, xim steel pobzeb puag daim hlau), machinery (txhawb, thawv), tsheb (carriage panels), cov khoom siv hauv tsev (plhaub, hauv paus), cov kav dej (welded yeeb nkab puag cov ntaub ntawv), cov khoom siv ua liaj ua teb thiab cov khoom siv dav dav.
