Lub tshuab hluav taws xob induction yog ib qho cuab yeej siv lub hauv paus ntsiab lus ntawm electromagnetic teb induction los hloov hluav taws xob hluav taws xob rau hauv hluav taws xob hluav taws xob kom sov thiab yaj cov nqi hlau. Raws li cov qauv, nws muab faib ua ob pawg: core induction rauv thiab coreless induction rauv.
Lub coreless induction rauv muaj qhov zoo ntawm kev ua haujlwm siab, txuag hluav taws xob, tsis muaj kuab lom, hloov tau yooj yim ntawm cov khoom sib xyaw, tswj tau yooj yim ntawm huab cua, muaj zog cua sov, thiab kev ua haujlwm tsis sib xws. Lub qhov cub induction tau muab faib ua: lub hwj chim zaus induction rauv (hauv 50Hz); nruab nrab zaus induction rauv (50Hz-10000Hz) thiab siab zaus induction rauv (siab tshaj 10000Hz). Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho thiab kev ntseeg tau ntawm high-power thyristor sib txawv zaus zog mov, lub nruab nrab zaus rauv tau maj hloov lub hwj chim zaus rauv. Piv nrog rau lub tshuab hluav taws xob zaus hluav taws xob, lub tshuab hluav taws xob nruab nrab ntawm lub tshuab hluav taws xob muaj kev ua haujlwm siab thermal thiab hluav taws xob ua haujlwm, lub sij hawm luv luv melting, tsawg zog noj, thiab kev siv tau yooj yim. qhov zoo ntawm automation. Tsis tas li ntawd, qhov cub induction yog tsim nyob rau hauv cov kev taw qhia ntawm lub peev xwm loj thiab lub zog siab, uas muaj cov kev xav tau ntau dua rau cov khoom siv refractory.
Refractory hauv ob sab phlu yog ib qho tseem ceeb uas txiav txim siab qhov tso zis ntawm induction rauv, casting zoo thiab kev nyab xeeb thiab kev ntseeg siab ntawm kev tsim khoom thiab kev ua haujlwm. Txhawm rau kom tau txais cov ntaub ntawv refractory nrog cov khoom zoo thiab kev pab lub neej ntev, peb yuav tsum xub nkag siab txog cov kev siv ntawm kev siv: (1) Lub thickness ntawm refractory hauv ob sab phlu yog siab heev. Nyias, kub gradient ntawm lub hauv ob sab phlu yog loj; (2) Lub electromagnetic stirring ntawm cov hlau molten nyob rau hauv lub cub tawg ua rau txhua yam yaig ntawm lub refractory hauv ob sab phlu; (3) Lub refractory hauv ob sab phlu yog rov quenched thiab thermally cuam tshuam.
Yog li ntawd, cov ntaub ntawv xaiv refractory yuav tsum muaj: txaus siab refractoriness thiab softening kub nyob rau hauv load; zoo thermal shock stability; tsis muaj tshuaj tiv thaiv nrog hlau thiab slag; ib tug tej yam kub kub mechanical zog; zoo rwb thaiv tsev thiab rwb thaiv tsev; kev tsim kho zoo, siab filling ceev, yooj yim sintering, yooj yim txij nkawm; Cov khoom siv ntau ntawm cov khoom siv refractory raw khoom, tus nqi qis, thiab lwm yam. Txoj kev loj hlob ntawm induction rauv yog ze ze rau kev kawm txuj ci ntawm cov ntaub ntawv refractory. Kev tsim hluav taws xob loj loj zaus crucible induction rauv feem ntau pib los ntawm kev xaiv cov ntaub ntawv refractory thiab simulation simulation ntawm lub cub tawg hauv ob sab phlu. Txawm li cas los xij, kev xaiv ntawm lub tshuab hluav taws xob hauv ob sab phlu refractories yog nyob ntawm 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 thinner lub hauv ob sab phlu, qhov zoo dua yog tsis cuam tshuam rau lub neej kev pab cuam.
