Dab tsi yog cov qauv ntawm silicon steel

Cov qauv ntawm silicon steel, tseem hu ua hluav taws xob steel lossis transformer steel, yog tus cwj pwm los ntawm ib qho kev qhia tshwj xeeb thiab microstructure uas muab cov khoom siv nws cov khoom sib nqus tshwj xeeb. Silicon steel feem ntau yog tsim nyob rau hauv daim ntawv ntawm nyias laminations, thiab nws cov qauv muaj cov nram qab no nta:

Grain Orientation:Silicon steel yog ua tiav kom muaj cov qauv zoo heev. Qhov no txhais tau hais tias cov nplej ntawm cov khoom yog ua raws li cov kev xav tau, feem ntau raws li cov kev taw qhia dov thaum tsim khoom. Qhov no grain orientation yog tiav los ntawm kev tswj dov thiab annealing txheej txheem. Cov txheej txheem cej luam yog qhov tseem ceeb rau kev ua kom zoo ntawm cov khoom siv hlau nplaum.

Laminations:Silicon steel yog feem ntau tsim nyob rau hauv daim ntawv ntawm nyias, ca laminations los yog nplooj ntawv. Cov laminations no tau muab tso ua ke los tsim cov tub ntxhais ntawm cov hluav taws xob hloov hluav taws xob, lub cev muaj zog, thiab lwm yam khoom siv. Kev siv cov laminations pab txo qis eddy tam sim no poob hauv cov tub ntxhais.

Insulating txheej:Txhawm rau tiv thaiv hluav taws xob luv luv ntawm cov laminations uas nyob ib sab thiab txhim kho cov khoom siv hluav taws xob rwb thaiv tsev, cov ntawv silicon steel feem ntau yog coated nrog ib txheej insulating. Cov txheej no tuaj yeem siv los ua cov txheej oxide nyias lossis cov kua roj vanish, nyob ntawm seb cov ntawv thov tshwj xeeb.

Cov ntsiab lus qis carbon:Silicon steel feem ntau muaj cov ntsiab lus carbon tsawg, feem ntau tsawg dua 0.005%. Cov ntsiab lus tsis tshua muaj carbon yuav pab txo qis hysteresis poob hauv cov khoom thaum raug hloov chaw sib nqus.

Silicon Cov ntsiab lus:Cov ntsiab lus ntawm silicon hauv silicon steel tuaj yeem sib txawv, tab sis nws yog ib qho tseem ceeb ntawm cov alloying. Silicon feem ntau tam sim no nyob rau hauv cov concentration ntawm 2% mus rau 4.5% los ntawm qhov hnyav. Qhov sib ntxiv ntawm silicon pab txo cov tub ntxhais poob thiab ua kom sib nqus permeability.

Yam tsawg kawg nkaus impurities:Silicon steel yog ua tib zoo ua kom muaj cov khoom tsis zoo xws li sulfur (S) thiab phosphorus (P), vim tias cov impurities no tuaj yeem cuam tshuam tsis zoo rau cov khoom siv hluav taws xob thiab cov khoom sib nqus.

Kev sib xyaw ua ke ntawm cov qauv coj ua, daim ntawv laminated, thiab cov ntsiab lus alloying tshwj xeeb, tshwj xeeb yog silicon, muab silicon steel nws cov khoom sib nqus zoo heev, suav nrog cov tub ntxhais uas tsis muaj qhov poob, siab sib nqus permeability, thiab siab saturation induction. Cov khoom no ua rau silicon steel cov khoom xaiv rau cov ntawv thov uas muaj zog hloov pauv thiab qhov sib nqus tsawg tsawg yog qhov tseem ceeb, xws li transformers, hluav taws xob motors, thiab generators. Kev ua tib zoo tswj cov qauv ntawm silicon steel yog qhov tseem ceeb rau kev ua tiav qhov xav tau hluav taws xob thiab sib nqus kev ua haujlwm hauv cov khoom siv no.
