Abstract:Through the micro-sintering equipment, the effects of carbon content and basicity on FeO content in sinter were investigated, as well as on liquid formation and bonding strength. In addition, suitable carbon content and basicity aimed at low FeO sintering was discussed on the base of it. The results show that: reduction in carbon addition or increase in basicity will bring about certain drop in FeO content in sinter. As for liquid formation in sinter, liquid phase fluidity first increases then decreases with the increase of carbon addition, and got the maximum when carbon addition is 4.0%, while it keeps rising with basicity increment. Besides, the strength of the bonding phase decreases slightly when carbon addition increases, but increases as basicity increases. Therefore, low carbon addition will cause the lack of liquid phase and decrease of sintering strength. Nevertheless, liquid phase formation and bonding strength would be ensured by improving the basicity. The results of sintering pot show that, when the carbon addition is 2.92% with improved basicity at 2.1, sinter of low FeO content but high quality and quantity is got.
