Saray Pandumaan na Cold Rolling tan Hot Rolling ed Saray Teknika na Panproseso

Say hot rolling tan cold rolling na nickel-based alloys et duaran importantin proseso na panag-roll, ya parehon manseserbi ed panagproseso na plastik. Mandumaan iran maong no nipaakar ed proseso tan produkto, tan mantutunosan so kimey da.

Say hot rolling et gagawaen ed tagey na temperatura na recrystallization (1000-1200℃). Diad pangusar na cast billets odino forged billets bilang raw materials, ondalan itan ed saray proseso a singa say homogenizing annealing, heating, multi-pass rolling (ya walay single pass reduction ya 10%-30% tan kapeles ya 1-5 m/s), maples ya panagpalemew, tan panag-descaling. Say gagala to et pian naekal iray depekto ed panag-cast, napino iray bukel, tan na-roll iray billet pian magmaliw ya mas makapal (Mas baleg nen say 3mm) a singa say medium tan heavy plates tan strip billets. Walay bentaha to ya makapanggawa na baleg ya deformation tan mamaaligwas ed mekanikal iran kablian na alloy. Balet, makapuy so kalidad na tapew to tan say inkasusto na sukat to (ya walay tolerance ya ±0.5mm) tan abeba so gastos to, kanian matukoy itan ed saray senaryo a singa saray makapal a dingding na tubo na nuclear power plant steam generators.

Say cold rolling et gagawaen ed silong na temperatura na recrystallization (temperatura na kuarto - 200℃). Diad pangusar na hot-rolled strips odino manipis iran plato bilang billets, kayari na surface treatment, sikatoy ondalan ed multi-pass rolling (ya walay single pass reduction ya 5%-20%, ya mankaukolan na dakel ya intermediate annealing pian nipawil so plasticity), insan say finish rolling, straightening, tan posiblin unor ya panagpainit. Say gagala to et pian nabawasan so kapal, napaaligwas so inkasusto na sukat (ya walay tolerance ya anggad ±0.005mm) tan say kalidad na tapew, tan napaaligwas so biskeg diad panamegley na work hardening. Makagawa itan na manipis iran plato tan ultra-manipis iran strips (Makulang odino mipara ed 3mm). Lapud atagey so gastos to, matukoy itan parad saray eksakton kabiangan a singa say atagey a temperatura na saray gasket na aero-engines.
