|
摘要
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。
The ferromanganese dephosphorization slags containing Ce_2O_3 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 Ce_2O_3 when the value of R was 1.05,and the peak values were 1 121.6 and 1 282.1 ℃,respectively. When the value of R was 0.97,the initial melting temperature and complete melting temperature decreased firstly and then increased with the increase of w(Ce_2O_3) and the minimum values were 1 008.8 ℃ and 1 148.5 ℃,respectively when the content of w(Ce_2O_3) was 3%. The viscosity of dephosphorization slags decreased firstly and then increased with the increase of w(Ce_2O_3),and the minimum values were 0.378 and 0.308 Pa · s as w(Ce_2O_3) was 3 % when the values of R were 1.05 and 0.97,respectively. The slags w(Ce_2O_3) was 3 % showed good melting and fluidity properties.
