Ol Difrens Namel Long Kol Roling Na Hot Roling Long Ol Teknik Bilong Prosesing

Hot roling na kol roling bilong ol nikel-bes aloi em tupela bikpela wok bilong rolim, tupela i save helpim wok bilong plastik. Ol i narakain tru long sait bilong proses na prodak, na wok bilong ol i helpim narapela narapela.

 

Ol i save mekim 'hot rolling' antap long 'recrystallization temperature' (1000-1200 digri). Taim ol i yusim ol 'cast billets' o 'forged billets' olsem ol 'raw materials', em i save go insait long ol wok olsem 'homogenizing annealing', 'heating', 'multi-pass rolling' (wantaim wanpela 'pass reduction' bilong 10%-30% na spit bilong 1-5 m/s), 'rapid cooling', na 'descaling'. As tingting bilong en em long rausim ol hevi long 'casting', klinim ol 'grain', na rolim ol 'billets' i go long ol samting we i tik moa (bikpela o wankain olsem 3mm) olsem ol 'medium' na 'heavy' plet na ol 'strip billets'. Em i gat ol gutpela samting long mekim bikpela senis na mekim ol 'mechanical properties' bilong 'alloy' i kamap gutpela moa. Tasol, em i no gat gutpela kwaliti bilong pes na stretpela mak (wantaim tolerans bilong ±0.5mm) na liklik pe, na dispela i mekim em i gutpela long ol samting olsem ol 'thick-walled tube billets' bilong ol 'nuclear power plant steam generators'.

 

Ol i save mekim 'cold rolling' aninit long 'recrystallization temperature' (rum tempereja - 200 digri ). Taim ol i yusim ol hot-ol strip o ol liklik plet olsem ol 'billet', bihain long ol i mekim wok long pes bilong en, ol i save mekim 'multi-pass roling (wantaim wanpela 'pass reduction' bilong 5%-20%, na i nidim planti 'intermediate annealing' long stretim bek 'plasticity'), bihain ol i save mekim 'finish rolling', stretim, na inap long kisim laspela tritmen. As tingting bilong en em long daunim 'thickness', stretim 'dimensional accuracy' (wantaim 'tolerance' inap long ±0.005mm) na 'surface quality', na strongim strong bilong en long rot bilong wok strongim. Em inap long kamapim ol liklik plet na ol liklik hap tru (Liklik o wankain olsem 3mm). Wantaim bikpela pe, em i gutpela long ol 'precision' komponen olsem ol 'high-temperature gaskets bilong ol 'aero-engine'.
