Dab tsi sab hauv tsis xws luag yog tshem tawm thaum lub sij hawm annealing txheej txheem ntawm galvanized coils?
Teb: Annealing ntawm galvanized coils feem ntau tshem tawm kev ua hauj lwm hardening generated thaum lub sij hawm txias dov, tso cov residual kev nyuaj siab nyob rau hauv cov hlau, thiab txhawb grain recrystallization, uas ua rau ib tug ntau uniform thiab ruaj khov microstructure. Qhov no zoo tiv thaiv kev tawg lossis deformation los ntawm kev ntxhov siab thaum lub sij hawm tom qab galvanizing.
Yuav ua li cas annealing cuam tshuam qhov zoo ntawm galvanized coils?
Teb: Annealing tshem tawm cov hlau oxide nplai thiab roj los ntawm cov hlau strip nto los ntawm qhov siab - qhov kub thiab txias txo qhov cua, ua rau kom huv thiab qhib qhov chaw. Qhov no txhawb nqa tag nrho cov tshuaj tiv thaiv ntawm molten zinc thiab steel substrate, tsim ib txheej txheej thiab ntom alloy. Qhov no txhim kho qhov adhesion thiab nto tiav ntawm txheej, txo qhov tsis xws luag xws li plating tsis tiav lossis tev.
Dab tsi tshwj xeeb kev txhim kho annealing coj mus rau txhua yam khoom ntawm galvanized coils?
Teb: Annealing txo cov yield zog thiab tensile lub zog ntawm steel strips thaum nce lawv elongation thiab plasticity. Tom qab annealing, stamping thiab tsim cov khoom ntawm galvanized coils yog kho kom zoo dua qub, ua kom yooj yim rau kev ua haujlwm tom ntej rau hauv ntau yam duab uas tsis ua rau tawg lossis tsis sib xws vim cov khoom siv ntau dhau.
Lub luag haujlwm dab tsi ua haujlwm hauv kev tiv thaiv "kev laus embrittlement" hauv galvanized coils?
Teb: Annealing zoo tshem tawm cov pa roj carbon thiab nitrogen atoms hauv cov hlau, txo cov kev sib txhuam sab hauv los ntawm lawv cov nag lossis daus ntawm chav tsev kub. Qhov no ua tau zoo inhibits kev laus embrittlement ntawm galvanized coils thaum lub sij hawm ntev - khaws cia los yog siv, ua kom cov khoom muaj zog ruaj khov thiab cuam tshuam, thiab txuas ntxiv nws lub neej kev pab cuam.
Vim li cas thiaj yuav tsum muaj kev tiv thaiv huab cua rau kev sib tsoo ua ntej galvanizing?
Teb: Annealing nyob rau hauv ib tug hydrogen-nitrogen sib xyaw tiv thaiv huab cua tiv thaiv cov hlau strip nto los ntawm re-oxidizing ntawm kub kub thiab ib txhij txo cov oxide films uas twb muaj lawm. Yog tias huab cua zoo tib yam siv rau kev sib tsoo, cov nplai oxide tuab yuav ua rau ntawm cov hlau nplaum, ua rau muaj kev cuam tshuam hnyav rau zinc- cov tshuaj tiv thaiv hlau thiab tiv thaiv kev tsim cov txheej txheem siab - zoo. Yog li ntawd, annealing nyob rau hauv ib qho chaw tiv thaiv yog ib qho tseem ceeb ua ntej yuav tsum tau ua kom tau zoo galvanizing zoo.
