Results ofan on-going investigation on properties of MgO-C monolithic refractories with tar-resin as binder are presented. Furthermore,the binder is an extremely strong carbon bonding. Further significant advantages of this system are high oxidation resistance of the highly-ordered carbon structure and the excellent stress-absorbing structure. To improve the strength anderosion resistance,and to decrease evaporation during heating,a preliminary treated tar-resin with higher melting temperature and lower content of volatile component was investigated. The binder specimens were treatedat 800℃ and the mechanical properties of MgO-C re-fractories specimens treated at 200,400,and 1 200℃ were determined.展开更多
