Abstract

Abstract: Simulative study on corrosion of Al_2O_3-C refractories by mold cover flux has been carried out by means of immersion method.The results show that there fractory exhibits best resistance to the flux corrosion while the ratio of additive Al and Si is approximately equal to one.In addi- tion,ZrO_2-C specimens exhibit better corrosion resistance to mold cover.flux than Al_2O_3-C specimens.

Key words: refractoty, Al_2O_3-C, continuous casting, corrosion
