含Ce2O3锰铁脱磷渣系熔化性质及黏度

 采用立式管式炉制备得到含Ce2O3锰铁脱磷渣系，分别利用HCT-2综合热分析仪和RTW-10型熔体物性仪对渣系的熔化性质和黏度进行测试分析。研究表明，碱度为1.05时，渣系的开始熔化温度和完全熔化温度随w(Ce2O3)]的增加而升高，其最大值分别为1 121.6和1 282.1 ℃；碱度为0.97时，渣系的开始熔化温度和完全熔化温度随w(Ce2O3)]的增加出现先降低后升高的趋势，当w(Ce2O3)]为3时出现最小值，分别为1 008.8和1 148.5 ℃。渣系的黏度值随w(Ce2O3)]的增加先降低后升高，当w(Ce2O3)]为3%时，黏度值最小。在碱度为1.05和0.97的脱磷渣系中，黏度最小值分别为0.378和0.308 Pa·s。因此，w(Ce2O3)]为3%时的锰铁脱磷渣系具有良好的熔化及流动特性。

Melting properties and viscosity of ferromanganese dephosphorization slag containing Ce2O3

The ferromanganese dephosphorization slags containing Ce2O3 have been prepared in vertical tubular furnace in this research. The melting properties and viscosity of slags have been achieved with TG-DTA thermal analysis instrument （HCT-2） and viscometer type （model RTW-10）， respectively. The results showed that the initial melting temperature and complete melting temperature of slags rose slightly with the increase of the content of Ce2O3 when the value of R was 1.05， and the peak values were 1 121.6 and 1 282.1 ℃， respectively. When the value ofR]was 0.97， the initial melting temperature and complete melting temperature decreased firstly and then increased with the increase ofw(Ce2O3)]and the minimum values were 1 008.8 ℃ and 1 148.5 ℃， respectively when the content ofw(Ce2O3)]was 3%. The viscosity of dephosphorization slags decreased firstly and then increased with the increase ofw(Ce2O3)]， and the minimum values were 0.378 and 0.308 Pa·s asw(Ce2O3)]was 3 % when the values ofR]were 1.05 and 0.97， respectively. The slags w(Ce2O3)]was 3 % showed good melting and fluidity properties.
