Paper Title:
Statistical Analysis of the Effect of Na2CO3 as Additive on the Reduction of Vanadic-Titanomagnetite-Coal Mixed Pellets
  Abstract

Vanadic-titanomagnetite-coal mixed pellets with minor addition of Na2CO3 were reduced isothermally at 900°C, 945°C, 1100°C, 1255.4°C and 1300°C. The variables parameters studied are temperature, the amount of carbon and the amount of Na2CO3 as additive. The experiment was designed with the technique of orthogonal regression in order to quantitatively assess the effect of each variable and the interactional effect of different variables. It is found that temperature, the amount of carbon and the amount of Na2CO3 as additive substantially influence the degree of reduction and metallization, and the presence of Na2CO3 can increase the reducibility of the pellets. The interaction of temperature and the amount of Na2CO3 have negative influences on the degree of reduction and metallization.
