Steel zombane: imveliso kunye nokusetyenziswa

Yokuba kuveliswe le hlobo ngentsimbi ithatha indawo ephambili phakathi kwezinye izinto ngemagnethi. steel Electrical - an intsila yesinyithi kunye lesilicon kunye umyinge ukusuka 0.5% ukuya-5%. ukuthandwa olu hlobo mveliso kunokucaciswa iimpawu eziphakamileyo kagesi nobomatshini. Ezenziwa steel amacandelo oqhelekilyo, apho kungekho intsilelo. Oku kuchazela abafundi ngendleko ephantsi.

Isiphumo electronic

Eli candelo libambisene kunye nentsimbi ukwenza isisombululo oxineneyo resistivity phezulu, ixabiso elandelwayo exhomekeke ipesenti lesilicon kwi ingxubevange. Phantsi nempembelelo kwi intsimbi ecocekileyo, ithe iimpawu zayo ngemagnethi. Kodwa xa zibethwa ekholejini, ngokuchasene noko, lwaba neempembelelo ezintle. Le permeability besinyithi kuyenyuka, ukuphucuka uzinzo intsimbi. Isiphumo anenzuzo lesilicon (Si) ukuze kucaciswa ngolu hlobo. Phantsi yempembelelo lwesi sakhi siqala grafayithi carbon yenguqu imo cementite leyo eye iipropati asezantsi ngemagnethi. Isiqalelo Si onesiphumo esibi ukuncitshiswa yoqheliso. impembelelo yayo wayengabalibali conductivity thermal kunye mninzi yentsimbi.

Elimsulwa kule ekwakhiweni

Xa isakhiwo sentsimbi umbane isenokuba nezinye izithako: isalfure, carbon, manganese, iphosphate kunye nabanye. Abo kakhulu yingozi - carbon (C). Kunokuba ibe kwifomu njengoko cementite, kunye mifanekiso. It lineziphumo ezahlukileyo ingxubevange, kwakunye ipesenti umxholo carbon. Ukuthintela inclusions engafunwayo element C, intsimbi akakwazi zipholile okulandelayo ngokukhawuleza ukuguga kunye nozinzo.

iziphumo ezibi iimpawu ezibonakalayo macandelo alandelayo: ioksijini, isalfure manganese. Banciphisa iimpawu zayo ngemagnethi. intsimbi Technical kumafa yayo ngokuyimfuneko uye ukungcola. Apha, kufuneka zithathelwe ingqalelo xa iyonke, hayi nje intsimbi enyulu.

Kuyenzeka ukuphucula iipropati ngentsimbi ngokusebenzisa ukuhlanjululwa ukungcola. Kodwa le ndlela akusoloko kuluncedo imveliso ngomlinganiselo omkhulu. Kodwa iifom intsimbi zombane abandayo Iphepha lothuli indawo ngemagnethi kubume bayo. Oku kukuvumela ukuba kuzuzwe iziphumo ezingcono. Kodwa usoloko ufuna ukudubula ngakumbi.

ehlelayo ebandayo

Kangangexesha elide sasikholelwa ukuba lesilicon kwandisa brittleness kwensimbi. Production kwenzeka kakhulu ehlelayo eshushu. Inzuzo ehlelayo ebandayo uphansi.

Kuphela emva kokuba kuye kwafunyaniswa ukuba abasebenzi abandayo kunye kwicala kwandisa iimpawu kazibuthe umbandela, iye isetyenziswe ngokubanzi. Ezinye iindawo baye babonisa kuphela ngesandla embi. Ingqele erhuqa kwamnceda kwiipropati mechanical, ngokunjalo nokuphucula umgangatho umphezulu sheet, le waviness nokwanda sokunyathela yayo yenziwe.

iimpawu ezikhethekileyo elithole intsimbi kombane ukusetyenziswa yokusebenza umkhuhlane kunokucaciswa ukuyilwa kwalo of texture crystallographic. Oku zizakubalulwa izidanga ezininzi. Nabo ke, kuxhomekeke iqondo lobushushu apho nomnombo udlula, nayo kwi Ebubanzini efunekayo wetshati kwaye kubungakanani apho crimped ngalo.

Iindleko noxwebhu liqengqiwe eshushu ubukhulu baba izihlandlo-2 ngaphantsi koko ngengqele. Kodwa le mfanelo embi lisisiqalo ngokupheleleyo ilahleko ephantsi ubushushu (amaxesha ngaphantsi kwe malunga ezimbini), umgangatho ophezulu kunye nokukwazi sokunyathela elungileyo abandayo liqengqiwe, ingxubevange. Umahluko phakathi kwezi yodidi - umxholo lesilicon. imali yawo isusela ukusuka 3.3% ukuya 4.5%, ngokulandelelana.

GOST

Abavelisi bavelisa ezimbini kuphela ngentsimbi ezihambelana GOST. Uhlobo lokuqala - 802-58 "Electrical asongwe". 9925-61 "Tape roll lokulayita intsimbi sombane" GOST sentsimbi zombane - yesibini.

abizwa

Ephawulwe ileta "E", kulandele inani, amanani kuzo zinentsingiselo eyodwa:

• Umvo lokuqala ixabiso kuthetha iqondo yophawulo steel alloying nge electronic. Ukusuka olova doped ukuya intsila ephakamileyo, ngokulandelelana kumabi Amanani-1 ukuya 4. ugesi - ngensimbi yamaqela A1 no-A2. Sombane - E3 kunye E4.
• Umvo Ukumakishwa yesibini enoluhlu ukusuka ku-1 ukuya 8. ibonisa iimpawu kagesi umbandela xa isicelo ngayo phantsi kweemeko ezithile yokusebenza. Kuba oku ukumakishwa ingafumaneka apho kwiindawo ungasebenzisa enye okanye ezinye ngentsimbi.

zero Digital emva digit yesibini ibonisa ukuba sobhedu textured. Ukuba kukho amaqanda amabini, ngoko ke a textured encinane.

Ekupheleni nokumakisha ingafunyanwa le ncwadi zilandelayo:

• "A" - ilahleko izinto ezithile iphantsi kakhulu.
• "P" - izinto ezityikitywe nge amandla ephakamileyo ekugqibeleni phezulu komhlaba.

Ububanzi ukusebenza

Lahlulwe ingxubevange Application ngokwendidi ezintathu:

• alungele ukusetyenziswa kwiinkalo eziphakamileyo neziphakathi nemagnethi (neengxaki magnetic ntumbuluko 50 Hz);
• alungele ukusetyenziswa kwiinkalo neyasesekondari ezitsho ukuya ku 400 Hz;
• steel, nesetyenziswa amasimi eliphakathi kwaye ezincinane sibubona ekukhanyeni.

sheets steel zombane impahla milinganiselo ilandelayo: ububanzi 240 ukuya kwi-1000 mm, ubude ibe ukususela 720 mm ukuya 2000 mm, esinobukhulu - ka-0.1 ukuya 1 mm. Zezona lwimi zisetyenziswa kakhulu ukuba textured intsimbi, ekubeni ixabiso eliphezulu lepropati kagesi. Sheets izinto ezinjalo adla ngokusetyenziswa kubunjineli yombane.

steel Electrical - Iimpahla

yenza ingxubevange Properties

• Resistivity. Ukususela kule index kuxhomekeke ngqo kwi umgangatho eziphathekayo. Steel isetyenziswa apho kuyimfuneko ukugcina umbane ngaphakathi ngumqhubi, eyihlangula kwindawo yayo engqongileyo.
• Amandla zonyanzelo. Inoxanduva lokuphendla isakhono lo mhlaba otsalayo zangaphakathi demagnetization. Kuba izixhobo ezithile, lo msebenzi efunekayo shiyana. Xa abaguquli kunye Motors wasebenzisa izinto iziphiwo ophezulu demagnetization. Kulo mzobo iye ezantsi. Kodwa abasebenza kufuneka, phezu koko, umkhosi omkhulu zonyanzelo. Ukulungisa iimpawu owahluke ngokwemvelo, yongeza ipesenti zinqwenelekayo lesilicon kwi ingxubevange ngentsimbi.

• Ububanzi yomtya hysteresis. Eli nani kufuneka ube sezantsi kangangoko kunako.
• permeability Magnetic. Ukuba uphakamile lo mzobo, ngcono umbandela 'ngokuhlangabezana' kunye imisebenzi yabo.
• Ububanzi sheet. Kuba nokuveliswa kwezixhobo ezininzi kunye nezinto iindawo ezisetyenzisiweyo, Ebubanzini ongadluli nawethu enye. Noko ke, ukuba kuyimfuneko, isibonisi kuyehla kube ixabiso 0.1 mm.

isicelo

Kokujonga sheet kwiklasi yokuqala, ungenza iintlobo ezahlukeneyo eesekethe otsalayo ukuba baphinde kunye nabalawuli.

Electrical nawo kwiklasi yesibini ingasetyenziselwa ukubala le DC sombane kunye AC ngoku, ukuba umphakathi le rotors. Kudidi lwesithathu ziya kuba zilungele ngokusungula umphakathi ngozibuthe ngenxa abaguquli igunya, kwakunye ukubala oomatshini ezinkulu yolunye.

Ukuvelisa itheko ukuba umatshini zombane, kuyimfuneko ukusebenzisa ngentsimbi uphose apho isiqulatho carbon ayikho ngaphezulu kwe-1%. Iimveliso ezenziwe oku phantsi annealed ngcembe. Carbon steel ezisetyenziswa xa kusenziwa iinxalenye umatshini phantsi iwelding. ukwenza kwipali esingundoqo koomatshini DC ezi ntlobo zezixhobo.

Kuba ezo ndawo umatshini leyo kuthwala umthwalo iphezulu (komnyaka, rotors, imiphini iiankile) lusetyenziswa aluminium ngempahla eliphezulu ngoomatshini. Loo elayibrari avotayo-nickel, chromium, molybdenum kunye Tungsten. Singakwazi ze umphakathi kazibuthe ngentsimbi zombane. Bona zisetyenziselwa abaguquli ephantsi rhoqo - 50Hz.

intonga magnetic

Magnetic ukwabelana ngazo kwi isikrweqe kunye core. uhlobo ngamnye awohluke zawo.

Intonga: in intonga Imagnethi ezifana nkqo kwaye icandelo cross wawanqanda abhaliwe kwisangqa. Bahlela imilo ekhethekileyo zezindlu ye Ikhoyili ngemagnethi.

isikrweqe

Products le yoyilo abe imilo buxande, kunye iintonga zabo babe icandelo umnqamlezo, ukuba zicwangciswe tyaba. Olu hlobo beesekethe magnetic lisetyenziswa kuphela izixhobo ezintsonkothileyo kunye noyilo. Ngoko ke, ezi zakhiwo musani zande.

Ngoko ke, safumanisa ukuba yentsimbi lombane kwaye isetyenziswa apho.
