| Abstract: | In order to improve the oxidation resistance of low carbon MgO-C brick,the effect of the addition of Al,Si and B4C on the oxidation behavior was investigated in the present work.The weight losses of samples during heating were determined by thermogrameter and the thicknesses of samples after oxidation test were measured.Moreover,the operational mechanism of the additives was discussed and an additive proposal for low carbon MgO-C brick was proposed.The results show that compared with Al and Si,the addition of B4C can improve the oxidation resistance of low carbon MgO-C brick efficiently.The low carbon MgO-C brick with B4C addition has excellent oxidation resistance.It is expected that this kind of brick has good slag resistance and thermal shock resistance,and it can meet the industrial requirement. |
