Pre-kho spcg txias coil yog pre-kho ua ntej yuav txias dov nrog ib tug txheej txheem hu ua pickling, uas siv muaj zog acids kom tshem tawmscale thiab lwm yam impurities. Cov Cold Rolled Steel yog tom qab ntawd dhau los ntawm cov yob kom txo nws cov tuab.
Cov ntaub ntawv ntau ntxiv ntawm pre-kho spcg txias coil qhia nyob rau hauv cov lus nram qab no SPCG tshuaj muaj pes tsawg leeg
QIB | C% max | Mn% max | P% max | S% max |
SPCG | 0.02 | 0.25 | 0.020 | 0.020 |
Feem ntau qhov txias dov yuav siv qhov chaw hauv multiplepasses thiab raws li qhov loj ntawm Cold Rolled Steel yog ntxiv txo, nws lub zog thiab hardness ob qho tib si nce, tab sis pre-kho spcg txias coil ductility txo.
