1000 cooling chungchangah . Decorative stainless steel pipe siam chhuahna kawngah hian hetah hian technical requirements hman a sang hle. Entirnan, temperature control a tha lo a, chu chuan 316 thermal stress leh structural stress a siam a nih chuan steel pipe chu a chhe thei a, a chhe thei bawk. Dawtchiah, HAGAO Tech (Seko Machinery) chuan cooling atan decorative stainless steel pipe siam chhuah dan hriatna chu chipchiar takin a rawn tarlang dawn a ni:
Processing laiin internal tension redistribution a awm avangin decorative stainless steel tube chu a chhe vek dawn a, processing accuracy pawh a awm thei dawn lo. Chu bakah, hmun lian tak tak enkawl hi residual stress a thlen awlsam hle bawk. Heng stainless steel decorative tube zawng zawng hian rough machining hnuah stress relief a titawp vek tur a ni. Internal stress annealing lakchhuah hi stainless steel tube chei nan a ni tlangpui. 500-550°C-ah chuan a hmain room temperature-ah minute 50 atanga 100 chhung, darkar 3 atanga darkar 5 emaw a aia tam (furnace dah zat a zirin) chhung rei tak chhung boruak tension awm reng turin hman a ni. Natural aging an ti a, mahse he method hi a sei lutuk a, a tlangpuiin hman a ni lo.
Stainless steel decorative tube chu a lum chuan a chung leh a hmun te thenkhat chu a tlangpuiin a dum, a khauh, a hring hring a siam chhuak thin. Chuvangin, stainless steel decorative tube pangngai chu casting defect awm lohna turin annealed emaw standardized emaw a ni tur a ni. Annealing emaw normalization temperature hi 850 leh 950°C inkar a ni tlangpui. Temperature chu darkar 1-2 chhung a awm a, cementite chu graphite leh austenite (graphitization stage hmasa ber) ah siam a ni. Kan Online continuous bright annealing furnace hian a pui thei che a ni. Preheating a mamawh lo, a tan hnu second 10 chhungin ideal annealing temperature a thleng thei.
Chubakah, PLC system nen a inzawm a, direct-in real-time data, real-time monitoring of air pressure, water flow, working temperature, speed te chu i hmu thei bawk. Furnace cooling period lo awm tur chhung hian secondary cementite leh eutectoid cementite te chu graphite-ah siam a ni ang (chu chu graphitization stage pahnihna) a ni ang. A tawp berah chuan perlite chu ferrite emaw ferrite matrix emaw-ah dahin, casting-a harsatna leh chakna a tihziaawm theih nan. Chu bakah, cementing process chu 850-950°C a ni a, mahse standardization process-a cementite, decorative stainless steel tube hardness-a cooling time tihtlem thei chuan pearlite matrix chakna leh hardness engemaw zat a hmu thei bawk.
