الوصف: This is an article in the field of metallurgical engineering, which proposed a new idea of mixing molten blast furnace slag with steel slag to achieve self-pulverization of steel slag, and systematically studied the influence mechanism of special components of CaF2 and CeO2 in blast furnace slag of Baotou Iron and Steel Company on the self-pulverization of steel slags. Using analytically pure CaO, SiO2, CaF2 and CeO2 as starting materials, pure C2S specimens were prepared with n ( CaO ) : n ( SiO2 ) = 2 : 1, then different mass fractions of CaF2 and CeO2 were added, respectively. The effect of CaF2 and CeO2 on the self-pulverization behavior of C2S was investigated by calcining the specimen at 1 450 °C for 1 h and cooling with the furnace. The results showed when CaF2 was incorporated into C2S and the content of CaF2 was less than 2.5%, it had little effect on the self-pulverization of C2S. However, when the content of CaF2 was more than 2.5%, the specimen had different degrees of agglomeration, which affected the self-pulverization of C2S. Considering that excessive CaF2 would affect the environment, the content of CaF2 should be controlled below 2.5%. When CeO2 incorporated into C2S and the content was 0.25%, C2S could still be completely self-pulverized, but when the CeO2 content was more than 0.5%, C2S no longer self-pulverized.Therefore, the CeO2 content must be less than 0.25 %, and the self-pulverization effect of C2S was relatively good.
