1.Dab tsi yog qhov txawv ntawm cov txheej txheem ntawm lub tswb -hom annealing thiab nruam annealing?
Tswb- hom annealing: steel coils yog stacked nyob rau hauv ib lub tswb - hom rauv thiab annealed rau ib tug ncua sij hawm, ua rau ib tug ntev ntau lawm voj voog.
Nruam annealing: Sawb steel tsis tu ncua hla ntau ntu ntawm lub qhov cub tawg (cua sov, soaking, thiab txias) rau kev kho cua sov sai, ua rau muaj kev ua haujlwm siab.
2.Dab tsi yog qhov txawv ntawm kev ua tau zoo ntawm lub tswb -hom annealing thiab nruam annealing?
Tswb- hom annealing: Cov khoom yog softer, nrog zoo plasticity thiab stamping zog, tshwj xeeb tshaj yog haum rau me me steels xav tau kev sib sib zog nqus nqus nqus.
Nruam annealing: Cov khoom muaj zog dua, tab sis kuj qis plasticity. Siab- steel muaj zog tuaj yeem tsim los ntawm cov thev naus laus zis txias txias (xws li NSC-CAPL, NKK-CAL, thiab lwm yam).
3.Dab tsi yog qhov txawv ntawm qhov zoo ntawm lub tswb - hom annealing thiab nruam annealing?
Bucket annealing: Cov teeb meem xws li lo, ntug khoov, thiab carbon dub yuav tshwm sim.
Nruam annealing: Tag nrho saum npoo yog du, tab sis pitting tsis xws luag yuav tshwm sim.
4.Yuav ua li cas lawv cais raws li txheej txheem?
Recrystallization annealing: tshem tawm txias dov ua hauj lwm hardening, tso cai rau deformed nplej kom recombine thiab loj hlob mus rau hauv equiaxed nplej, thiab restores plasticity.
Incomplete annealing: ua rau theem transformation los yog recrystallization nyob rau hauv qhov chaw ntawm steel qauv, txo hardness thiab relieving kev nyuaj siab.
Tag nrho annealing: Tau txais qhov sib npaug microstructure ntawm ferrite thiab pearlite, refines nplej, thiab txo hardness.
Bright annealing: nqa tawm hauv qhov chaw tiv thaiv (xws li H₂, N₂) txhawm rau tiv thaiv oxidation ntawm steel nto thiab tau txais lub ci, oxide-dawb nto.
5.Yuav xaiv thiab txiav txim li cas?
Xaiv cov txheej txheem raws li daim ntawv thov: Xav txog koj cov kev txhawj xeeb yav dhau los txog stamping cracking thiab wrinkling, yog hais tias ib feem yog ib tug sib sib zog nqus- stamped tivthaiv (xws li automotive roj lauj kaub los yog ib tug complex appliance liner), nws yog feem ntau pom zoo kom ua ntej txias txias- dov coils tsim siv lub hood-annealing, zoo dua rau cov txheej txheem yas (BA). Rau kev khoov los yog qhov chaw tiaj tus, tsis tu ncua annealed (CAL) cov khoom tsim nyog.
Txoj kev qhia ceev ceev: Rau cov khoom siv steel hlau (xws li Baosteel thiab Maanshan Hlau & Hlau), qee zaum cov qauv coding ntawm tus lej coil lossis cov lej xov tooj tuaj yeem qhia tau hais tias nws yog ib qho txuas ntxiv los yog hood- cov khoom lag luam annealed. Tau kawg, txoj kev txhim khu kev qha tshaj plaws yog ncaj qha mus xyuas cov khoom lag luam daim ntawv pov thawj zoo, uas yuav qhia meej txog cov txheej txheem tsim khoom.
