Q: Dab tsi yog ua haujlwm hnyav?
A: Cov khaub ncaws txias yog txheej txheem ntawm kev txo cov phaj tuab thiab ua kom muaj zog ntxiv, thiab kev tshem tawm kom tsawg dua (Kuv {. "ua haujlwm hardening "lossis" ua haujlwm txias ua haujlwm hnyav ") .
Q: Li cas annealing tshem tawm ua haujlwm tawv?
A: Lub hauv paus ntsiab lus: Tshav kub sov-rolled steel phaj mus rau saum toj no cov recrystallization kub, thiab tom qab ntawd maj mam txias nws.
Muaj nuj nqi: Cov atoms sab hauv cov phaj steel txais lub zog thiab rov kho cov khaub ncaws tshiab (recrystallization), tshem tawm cov crystal distortion thiab dislocation ntxiv;
Lub hardness yog txo thiab cov plastonity tau rov qab, kom cov steel phaj muaj kev ua tiav zoo dua .
Q: Dab tsi txhim kho tau tiav tom qab annealing?
A: {{1.} Xaiv qhov chaw zoo
Thaum lub sij hawm txias txias, rolling roj, oxides los yog purifies stain cleaning thiab kev ua kom zoo nkauj ntawm lub galvanized txheej .
Kev sib piv: Yog tias kev sib piv tsis tau ua, seem uas muaj cov txheej txheem ntawm galvanized rau "tev" lossis "tev".
2.} tswj cov khoom siv mechanical tshuab ntawm substrate
Galvanized steel rau cov laj thawj sib txawv muaj cov cai tshwj xeeb rau lub zog thiab elongation ntawm substrate .
Annealing tuaj yeem tswj tau qhov tseem ceeb, elongation thiab hardness thiab hardness ntawm substrate los ntawm kev kho qhov cua sov cua sov thiab txias tus nqi .
Lub Hom Phiaj: Kom phim cov kev ua tau zoo ntawm cov txheej txheem nrog cov txheej galvanized kom tau raws li cov kev xav tau ntawm kev ua tiav lossis siv scenarios {}}
Q: Hom txheej txheem anealing hom?
A: {1.}} nruam annealing
Process: The cold-rolled steel plate passes through the heating section, insulation section, and cooling section in a continuous furnace, and is in a protective gas throughout the process to avoid oxidation.
Nta: Kev tsim kev ua haujlwm siab, sib zog ua tiav kev ua tau zoo, haum rau huab hwm coj kev tsim khoom xws li cov khoom siv tsheb hluav taws xob thiab cov khoom siv hauv tsev.
{{0} hood annaling
Txheej Txheem: Cov Hlau Steel yog dov rau hauv lub hood annealing rauv, thiab tom qab ntawd cov roj tiv thaiv kom maj mam sov thiab txias .
Nta: Tus nqi qis, tab sis cov khoom lag luam qis, haum rau me me thiab nruab nrab steel nrog cov kev ua tau qis.
Q: Qhov kev tsis zoo ntawm kev tsis raug cai?
A: {{1.} substrate kev ua tau zoo tsis tsim nyog
Annealing kub yog tsis txaus lossis lub sijhawm luv heev: ua haujlwm tawv heev tsis raug tshem tawm tag nrho, lub phaj steel tseem nyuaj dua tom qab galvanizing.
Annealing kub dhau los lossis lub sijhawm ntev heev: "overstrate"), lub zog muaj peev xwm cuam tshuam yog cuam tshuam {}}
{{0 {} galvanized txheej tsis xws luag
Cov txheej txheem Oxide lossis roj tseem tshuav: lub galvanized txheej muaj cov khoom tsis zoo thiab yog ib qho yooj yim poob tawm (xws li zinc txheej peeling hauv tej daim thaum khoov);
Txawv txav ntawm lub substrate: ua rau tsis sib xws ntawm cov galvanized txheej (xws li kev siv lub zos overthickness (thinnessness) .
