Hluav taws xob cov steel: zus thiab siv

Zus tau tej cov no hom ntawm steel occupies ib tug leading qhov chaw ntawm lwm cov magnetic cov ntaub ntawv. Hluav taws xob cov steel - ib tug hlau hlau silicon nrog ib tug kev faib ua feem ntawm los ntawm 0.5% mus rau 5%. Thoob plaws muaj koob meej ntawm qhov no zoo ntawm cov khoom yuav tsum tau piav los ntawm lub siab electromagnetic thiab txhua yam khoom. Manufactured los ntawm steel tej chaw Cheebtsam, nyob rau hauv uas tsis muaj nyiaj tsawg. Qhov no qhia rau nws tsis muaj nqi.

Nyhuv ntawm silicon

Qhov no feem nyob rau hauv nrog hlau los tsim ib tug tuab tshuaj ntawm siab resistivity, tus nqi uas nyob rau ntawm qhov feem pua ntawm silicon nyob rau hauv lub hlau. Nyob rau hauv tus ntawm nws nyob rau ntshiab hlau, nws loses nws sib nqus. Tab sis thaum raug mus kawm college, on qhov tsis tooj, ib tug zoo feem. Lub permeability ntawm cov hlau yog nce thiab kev txhim kho ntawm lub stability ntawm cov hlau. Cov nyhuv lig ntawm silicon (Si) tej zaum yuav tau piav raws li nram no. Nyob rau hauv tus ntawm no los mus rau hauv graphite carbon xeev txoj kev hloov ntawm cementite uas muaj qis sib nqus. Lub caij Si muaj ib tug phiv ntxim rau cov yuav txo tau ntawm induction. Nws txhob ncua mus rau thermal conductivity thiab cov kev ceev ntawm hlau.

Impurities nyob rau hauv muaj pes tsawg leeg

Nyob rau hauv cov qauv hluav taws xob steel tej zaum yuav muaj lwm cov khoom xyaw: leej faj, carbon, manganese, phosphorus thiab lwm tus neeg. Cov teeb meem feem ntau sawv daws yuav - carbon (C). Nws yuav ua tau nyob rau hauv daim ntawv raws li cementite, thiab graphite. Nws muaj sib txawv los rau hauv lub hlau, raws li zoo raws li qhov feem pua ntawm cov pa roj carbon cov ntsiab lus. Kom tsis txhob pliaj inclusions caij C, steel tsis tau txias rau tom ntej no sai sai laus thiab stabilization.

Cov nyom zoo nyob rau thaj chaw ntawm cov ntaub ntawv uas muaj cov nram qab Cheebtsam: pa, sulfur thiab manganese. Lawv txo nws magnetic qualities. Kev hlau nyob rau hauv nws muaj pes tsawg leeg tas muaj impurities. Ntawm no, lawv yuav tsum tau coj mus rau hauv tus account raws li ib tug tag nrho, tsis yog raws li ib tug dawb huv hlau.

Nws yog ua tau los txhim kho thaj chaw ntawm steel uas tso npe thov purification los ntawm impurities. Tab sis qhov no txoj kev yog tsis ib txwm zoo rau cov loj-scale lawm. Tab sis los ntawm tus mob khaub thuas dov daim ntawv hluav taws xob steel ntaub ntawv ib tug sib nqus khoom nyob rau hauv nws cov qauv. Qhov no tso cai rau koj mus cuag qhov zoo tshaj plaws kev tshwm sim. Tab sis yeej ib txwm xav tau kev pab ntxiv firing.

txias ntxuag

Rau ib ntev lub sij hawm peb ntseeg hais tias pob zeb ntais tsub kom lub brittleness ntawm hlau. Qhuav coj qhov chaw tsuas yog los ntawm kub dov. Profitability txias ntxuag yog tsawg.

Tsuas yog tom qab nws tau raug pom tias tus mob khaub thuas ua hauj lwm raws li ib cov kev taw qhia tsub kom lub sib nqus ntawm cov khoom, nws tau lug siv. Lwm yam chaw tau qhia lawv tus kheej tsuas muaj qhov phem tshaj txhais tes. Khaub thuas dov ib tug nyhuv lig rau tus neeg kho tshuab zog, raws li zoo raws li kev txhim kho qhov zoo ntawm cov ntawv nto, lub waviness thiab muaj zog nws enabled Stamping.

Yus zog uas tau txais hluav taws xob steel los ntawm kev siv ntawm no ua hauj lwm muaj peev xwm yuav piav los ntawm tus tsim nyob rau ntawd ntawm crystallographic kev ntxhib los mos. Nws yog txawv los ntawm ob peb degrees. Lawv, nyob rau hauv lem, nyob ntawm seb qhov kub thiab txias thaum uas dov kis, tseem nyob rau lub thickness yuav tsum tau ntawm daim ntawv thiab nyob rau hauv raws li qhov uas nws yog crimped.

Nqi ntawm ib tug kub dov daim ntawv thickness los ua 2 lub sij hawm tsawg dua uas mob khaub thuas. Tab sis qhov no tsis zoo zoo kiag li offset tsawg tshav kub losses (ntawm tsawg tshaj ob sij hawm), kev zoo siab thiab ib tug zoo Stamping muaj peev xwm txias dov hlau. Qhov txawv nyob rau hauv cov steels - lub pob zeb ntais cov ntsiab lus. Nws npaum li cas yog hom twg los ntawm 3.3% 4.5%, ntsig txog.
