Ntev npaum li cas siv lub hauv ob sab hauv ntawm induction melting rauv?

1. Cov ntaub ntawv masonry rau hauv ob sab phlu ntawm lub cub tawg phab ntsa ntawm induction melting rauv yog feem ntau quartz xuab zeb thiab siab alumina cov ntaub ntawv. Cov khoom siv alumina siab dua yog tsim rau induction melting furnaces hauv qab 500kg, thiab lub cub tawg phab ntsa ntawm induction melting furnaces saum 500kg yog ua los ntawm qhuav quartz xuab zeb.

2. Quartz xuab zeb yog qhov zoo tshaj plaws rau smelting rauv. Quartz xuab zeb cov khoom yog tsim los ntawm cov ntxhia hauv ntuj, thiab nws qhov zoo yog nyob ntawm cov ntsiab lus ntawm SiO2 thiab nws cov qauv me me. Kev hloov pauv ntawm cov khoom siv hluav taws xob hauv lub tshuab hluav taws xob tuaj yeem ua rau lub cub tawg ua kom lub neej ntev. Cov kab hluav taws xob ua hluav taws xob yog cov kab hluav taws xob ua hluav taws xob ua los ntawm cov kua qaub oxide. Cov oxide siv los ua cov hauv ob sab phlu ntawm cov kua qaub rau cov phab ntsa yog SiO2. Yuav luag tag nrho cov kua qaub rauv phab ntsa hauv ob sab phlu yog ua los ntawm cov ntaub ntawv refractory raws li SiO2, uas yog tshwj xeeb tshaj yog haum rau loj-scale induction furnaces nrog lub peev xwm ntawm 5-30T. Los ntawm kev sim, thawj hom ntawm lub cev thiab tshuaj ntsuas ntawm quartz xuab zeb muaj qhov nthuav dav coefficient ntawm 7% -9%, thiab hom thib ob muaj qhov nthuav dav ntawm 0.5% -2%. Hom thib ob thiab qhov loj me me yog qhov tsim nyog rau kev siv lub tshuab ua kom sov phab ntsa ntawm lub qhov cub induction melting. .
