Core Reason: Plasticity siam that leh a, a crack loh nan
1. Hnathawh khauh zawk
Stainless steel raw material (a tlangpuiin coiled material) hian factory atanga a chhuah veleh chakna leh khauhna engemaw zat a nei a, chubakah ductility tha tak a nei bawk. Mahse, phurh chhuah, dahkhawm, a tir lama blanking leh stamping-naah te chuan thil chu plastic deformation engemaw zat a tawk a ni. Hetiang deformation hian metal lattice chu a tidanglam a, dislocation density a tisang a, chu chuan a chakna leh a khauhna a tipung a, mahse plasticity leh toughness a ti tlahniam thung. He thil thleng hi "work hardening" tia hriat a ni.
2. Deep Drawing lama harsatna awm thei
Sheet flat, round tak chu barrel-shaped inner liner thuk takah hrual chu plastic deformation process dramatic leh complex tak a ni. Material flow langsar tak, inang lo tak a mamawh a ni. "work hardened" tawh material khauh takah deep drawing tih a nih chuan, chu material-a inherent ductility chu hetiang deformation lian tak hmachhawn tur hian a tawk lo. Chumi avang chuan drawing process chhung hian hmun chak lo ber (a tlangpuiin corner emaw base emaw) ah "crack" a awm ang.
Annealing-in a chanvo: Material State chu "Resetting" a ni
Annealing hi heat treatment process a ni a, chu chuan material microstructure chu heating leh cooling hmangin a tidanglam thin. Hetah hian thil tum ber chu work hardening tihbo vek hi a ni. A tir lama deformed stainless steel workpiece chu a recrystallization temperature (304 ang austenitic stainless steel tan chuan a tlangpuiin 1040-1120 degree) aia sang thlengin an vawt a, he temperature-ah hian hun engemaw chen an vawn a, chutah chuan controlled condition-ah an vawt a ni.
Microscopic hmanga inthlak danglamna:
Annealing heating process chhung hian cold-deformed, distorted crystal lattice chuan "recrystallization" process a paltlang a, chu chuan grain te tak te, stress-free, equiaxed thar a siam a ni. Cold work-in a rawn thlen dislocation leh internal stress zawng zawng chu a bo vek a ni.
Macroscopic atanga a chhuah dan:
Material chakna leh khauhna nasa takin a tlahniam a ni.
Material plasticity leh ductility chu a optimal state-ah a kir leh a, "soft" tak a ni ta a ni.
Hetih lai hian stainless steel sheet chu dough ang mai a ni a, awlsam tak leh thuk takin a inzawm khawm thei a, a chhe lo

What Machine hian Stainless Steel Pot atana annealing process a siam thin
Induction Annealing Machine - Localized heat treatment atan a tha, stainless steel pot ang chi
Hnathawh dan: Induction coil hian magnetic field danglam tak a siam a, stainless steel pot chhungah eddy current a siam a, chu chuan a ti lum ta a ni. He machine hian a tlangpuiin pot chhunga hmun bik (stretching mamawhna hmun ang chi) chu a ti lum nghal vat thin. Hei hi stainless steel pot siamna atan a tha hle. Secondary stretching process kan tih hmain stainless steel pot 7-8 cm opening chu kan anneal hmasa phawt a ngai a ni.
A thatna pawimawh tak tak:
1. Heating speed chak tak: Annealing temperature hi second sawm chhungin a thleng tlangpui.
2. Energy efficiency: Energy hi hnathawhna hmunah direct-a dah a ni a, chu chuan thermal efficiency sang tak a siam a ni.
3. Production line-a awlsam taka inzawmkhawm: Workpiece pakhat zel in{1}}line processing chak taka hman theih turin machine bik siam theih a ni
