Qhov zoo tshaj plaws aluminium dawb castable preform muab los ntawm peb lub tuam txhab yog cov khoom sib xyaw ua ke nrog ultra-nplua hmoov. Cov khoom insoluble nyob rau hauv aluminium yog ntxiv, thiab nws hardly ntub nrog txhuas kua. Yog li ntawd, lub wettability thiab permeability ntawm txhuas kua rau cov khoom yog zoo tiv thaiv. Nyob rau hauv tus txheej txheem ntawm kev siv, yuav luag tsis muaj nodule thiab txhuas, uas zoo txo qhov poob ntawm txhuas kua.
High quality aluminium dawb castable preform daws qhov teeb meem ntawm tsis hnov mob nrog txhuas kua, thiab muaj zog muaj peev xwm ntawm resisting txhuas kua corrosion thiab nkag mus. Thaum siv, nws muaj qhov zoo thermal shock tsis kam. Yog li ntawd, nws tau txais kev pabcuam zoo thiab kev pabcuam lub neej, zoo dua rau lwm cov khoom siv refractory.
