DETERMINATION OF OXYGEN POTENTIAL FOR PANZHIHUA IRON ANK STEEL Co. BLAST FURNACE METAL ANK SLAG

The oxygen probe made specially,sealed by refractory cement and adopting ZrO₂ base solid electrolyte tube, reference electrode with Cr.Cr₂O₃ powders,Mo electrode lead wire,has a good measuring stability.By experiments,the oxygen potential for high TiO₂ containing blast furnace slag is determined,successfully.It shows,by the measured results, that the oxygen partial pressure of Panzhihua Iron and steel Co. blast furnace slag is about 1.01325×10^-9pa and is round 100 times higher than general blast furnace slag.
