Cold Rolled lan Cold Hard Coil

Cold Rolled lan Cold Hard Coil

Cold Hard coil diduweni dening pickling lan kadhemen Rolling gulungan panas mbalek.Iki minangka jinis gulungan gulungan kadhemen.

Cold rolled coil (annealed state): hot rolled coil liwat pickling, cold rolling, hood annealing, leveling, (finishing), bisa njaluk Cold rolled coil.

Bedane antarane Cold Rolled lan Cold Hard:

1. Saka katon, piring Hard kadhemen iku werna Micro Black sethitik umume

2.Kualitas permukaan, Struktur lan Ukuran presisi Cold Rolled luwih apik tinimbang Cold Hard.

3. Ing kinerja:

Wiwit Cold Hard coil dijupuk langsung dening proses rolling kadhemen, ing proses rolling kadhemen karya hardened sak rolling kadhemen, kekuatan ngasilaken mundhak lan sawetara kaku internal tetep, lan katon external relatif hard, supaya disebut Cold Hard coil..

Cold-rolled coil (annealed state): coil hard kadhemen dipikolehi kanthi annealing hood sadurunge digulung.Sawise annealing, fenomena hardening karya lan stres internal diilangi (secara substansial suda), yaiku, kekuatan ngasilake suda nganti meh kadhemen.Sadurunge muter.

Mulane, kekuatan ngasilake: kumparan hard kadhemen luwih gedhe tinimbang kumparan kadhemen-mbalek (negara annealed), supaya kumparan kadhemen-mbalek (negara annealed) luwih sarujuk kanggo stamping.
