Procedure for the production of refractory material electrofundido moldeable by colada (Machine-translation by Google Translate, not legally binding)

摘要

Process for the production of melt-cast electroflowed refractory material, consisting essentially of crystalline alumina and zirconium oxide within a vitreous matrix, characterized in that it comprises a pretreatment phase of the raw materials used in order to increase its purity, a refining phase, after melting, of zirconium minerals, then a quenching phase of the blocks after casting at a temperature varying between 1300º C and 1600º C, as a result of which the vitreous phase, which contains a considerable amount of zirconium oxide and sodium oxide, retains sufficient viscosity to allow a definitive stabilization of the crystalline and vitreous phases, and finally a controlled cooling phase.
