khoom piav qhia
Arc-puab refractory cib tseem hu ua arc cib. High-alumina arc bricks yog ib hom tshwj xeeb zoo li tus cib. Lub arc ntawm cov av cib yog ib nrab ncig thiab lwm qhov kawg yog qhov zawj. , Tseem tuaj yeem tsim ua lub voj voos, hom cib no yog siv hauv cov pob tawb. Cov av cib feem ntau yog siv ua txheej sab hauv ntawm lub thoob hlau. Nws siv los ua av nplaum. Tam sim no nws tau maj mam hloov los ntawm cov cib alumina siab. Cov cib alumina siab tau zoo los ntawm cov cua sov ua haujlwm tsis zoo, muaj zog tiv taus thiab muaj zog siab.
High-aluminium arc refractory bricks muaj aluminium silicate nrog Al2O3 siab dua 48% txog 75%. Qhov siab dua cov ntsiab lus txhuas, zoo dua qhov zoo ntawm qib siab-txhuas arc cib. Nws yog cov khoom tsis muaj zog acidic refractory, uas yog ua los ntawm cov khoom siv ntuj los yog khoom siv high-alumina (sillimanite, diaspore, alumina siab, thiab lwm yam). Piv nrog cov av nplaum cib, nws cov refractoriness (1750 ~ 1790 ℃) thiab thauj khoom kub ua kom sov (1420 ~ 1500 ℃) siab dua, thiab nws cov slag tsis kam thiab lub zog sib zog kuj tseem siab dua.
