Kuthiwani ngokusebenza kwe izitini zobumba eziphikisayo?

Izitini eziphikisayo zobumba ziyimikhiqizo ephikisayo ene-asidi ebuthakathaka, engamelana nokuguguleka kwe-asidi slag negesi ye-asidi, futhi ibe nokungazweli kahle kwezinto ze-alkali. Izitini ze-clay refractory zinezakhiwo ezinhle zokushisa futhi zimelana nokubanda okusheshayo nokushisa okusheshayo.

Ukumelana nomlilo kwezitini eziphikisayo zobumba kulingana nalokho kwezitini ze-silica, ezifinyelela ku-1690～1730℃, kodwa izinga lokushisa elithambile ngaphansi komthwalo lingaphansi kuka-200℃ kunalelo lezitini ze-silica. Ngenxa yokuthi izitini eziphikisayo zobumba aziqukethe kuphela amakristalu e-mullite ane-refractoriness ephezulu, kodwa futhi aqukethe cishe ingxenye yesigaba sengilazi ye-amorphous enephuzu eliphansi lokuncibilika.
