Lub cub tawg induction yog ib lub cuab yeej uas siv lub hauv paus ntsiab lus ntawm electromagnetic field induction los hloov hluav taws xob mus rau hauv lub zog cua sov kom sov thiab yaj cov hlau. Raws li cov qauv, nws muab faib ua ob pawg: lub cub tawg induction core thiab lub cub tawg induction coreless.
Lub cub tawg induction tsis muaj lub hauv paus muaj qhov zoo ntawm kev ua haujlwm zoo, txuag hluav taws xob, tsis muaj kuab paug, yooj yim hloov kho cov khoom sib xyaw, yooj yim tswj huab cua, muaj peev xwm ua kom sov tau zoo, thiab ua haujlwm tsis tu ncua. Lub cub tawg induction muab faib ua: lub cub tawg induction fais fab zaus (hauv 50Hz); lub cub tawg induction nruab nrab zaus (50Hz-10000Hz) thiab lub cub tawg induction siab zaus (saum toj no 10000Hz). Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho thiab kev txhim kho kev ntseeg siab ntawm lub zog siab thyristor hloov pauv zaus fais fab mov, lub cub tawg zaus nruab nrab tau maj mam hloov lub cub tawg zaus fais fab. Piv nrog rau lub cub tawg zaus fais fab, lub cub tawg zaus nruab nrab muaj kev ua haujlwm thermal zoo thiab hluav taws xob zoo, lub sijhawm yaj luv luv, kev siv hluav taws xob tsawg, thiab kev siv yooj yim. qhov zoo ntawm kev ua haujlwm tsis siv neeg. Tsis tas li ntawd, lub cub tawg induction tab tom txhim kho hauv kev coj ntawm lub peev xwm loj thiab lub zog siab, uas muaj cov kev xav tau ntau dua rau cov ntaub ntawv refractory.
Cov ntaub thaiv hluav taws xob yog ib qho tseem ceeb uas txiav txim siab qhov tso zis ntawm lub cub tawg induction, qhov zoo ntawm casting thiab kev nyab xeeb thiab kev ntseeg siab ntawm kev tsim khoom thiab kev ua haujlwm. Yuav kom tau txais cov ntaub thaiv hluav taws xob nrog cov khoom zoo thiab lub neej ntev, peb yuav tsum xub nkag siab txog cov xwm txheej ntawm kev siv: (1) Lub thickness ntawm cov ntaub thaiv hluav taws xob yog qhov siab heev. Nyias, qhov kub ntawm cov ntaub thaiv hluav taws xob loj; (2) Lub electromagnetic stirring ntawm cov hlau molten hauv lub cub tawg ua rau cov khoom siv hluav taws xob puas tsuaj ntawm cov ntaub thaiv hluav taws xob; (3) Cov ntaub thaiv hluav taws xob raug quenched ntau zaus thiab cuam tshuam los ntawm thermally.
Yog li ntawd, cov ntaub ntawv refractory xaiv yuav tsum muaj: siab txaus refractoriness thiab softening kub nyob rau hauv load; zoo thermal shock stability; tsis muaj tshuaj lom neeg tshuaj lom neeg nrog hlau thiab slag; ib qho kub siab mechanical zog; zoo rwb thaiv tsev thiab rwb thaiv tsev; kev tsim kho zoo, siab filling ceev, yooj yim sintering, yooj yim txij nkawm; muaj ntau cov khoom siv refractory raw, tus nqi qis, thiab lwm yam. Kev txhim kho ntawm induction cub tawg yog ze rau kev nce qib ntawm cov ntaub ntawv refractory. Kev tsim ntawm lub zog loj zaus crucible induction cub tawg feem ntau pib los ntawm kev xaiv cov ntaub ntawv refractory thiab kev sim ua qauv ntawm lub cub tawg hauv pem teb. Txawm li cas los xij, kev xaiv ntawm lub cub tawg hauv pem teb refractories yog raws li kev siv thiab kev lag luam ntawm lub cub tawg. Rau lub hom phiaj ntawm kev sib txuas nruj ntawm cov khoom siv hluav taws xob, qhov nyias dua qhov tuab ntawm lub hauv paus, qhov zoo dua nws yog yam tsis cuam tshuam rau lub neej kev pabcuam.
