Q: Dab tsi yog qhov ua rau khoov tawg?
A: Kev sib koom ua ke ntau dhau (xws li MnS), qhov tsis sib xws ntawm microstructure, ntug burrs / microcracks, txheej txheem txias txias tsis zoo (tso me me dabtsi yog khoov mandrel, nrawm nrawm nrawm).
Q: Yuav ua li cas los txiav txim seb Q235 coil puas zoo?
A: Tshawb xyuas daim ntawv pov thawj zoo (muaj pes tsawg leeg, txhua yam khoom, qhov ntev, qib nto); xyuas kom tsis txhob muaj qhov tsis xws luag hauv qhov tsos; ua random checks ntawm mechanical/process properties thiab dimensional tolerances raws li cov qauv.
Q: Dab tsi yog cov qauv kam rau ua rau Q235 kauj?
A: Thickness kam rau ua raws li GB / T 3524. Rau thicknesses ntawm 2-6mm, qhov dav dav precision yog ± 0.15mm; dav kam rau ua yog ± 5mm. Cov kev cai tshwj xeeb yog ua raws li daim ntawv cog lus / tus qauv.
Q: Dab tsi yog cov teeb meem ntug thiab kev daws teeb meem rau Q235 kauj?
A: Ntug tawg, burrs, thiab tapered duab; tswj qhov zoo ntawm tsis tu ncua cam khwb cia billets, optimize lub finishing dov sab qhia daim hlau thiab coiling nro, thiab luas los yog chamfer npoo yog tsim nyog.
Q: Yuav ua li cas los daws qhov teeb meem ntawm cov hlau oxide tuab heev ntawm Q235 kauj? A: Txo cov cua sov thiab lub sijhawm ua kom sov, ua kom zoo dua cov dej siab (Ntau dua lossis sib npaug ntawm 18MPa), siv cov dej siab siab - siab rau qhov nruab nrab descaling, thiab txias thiab ntim cov khoom coiled tam sim ntawd.
