Al2O3和Cr2O3对自蔓延冶金法制备 CuCr合金冶炼渣性能的影响

自蔓延冶金法制备CuCr合金时，合金中的Al₂O₃和Cr₂O₃夹杂物会在熔渣精炼过程中被冶炼渣溶解，改变熔渣成分，从而影响冶炼渣的熔点、黏度、密度和表面张力等性能，给精炼过程带来不利影响.使用熔体物性测定仪针对Al₂O₃和Cr₂O₃含量变化对冶炼渣的性能影响规律进行了研究，结果表明:Al₂O₃和Cr₂O₃含量的增加均可以提高熔渣的黏度、凝固温度和表面张力，Cr₂O₃对黏度和表面张力的影响较大，Al₂O₃对凝固温度的影响较大；Al₂O₃使熔体密度上升，Cr₂O₃使熔体密度先上升后下降. 

Effects of Al2O3 and Cr2O3 on properties of smelting slag used for the preparation of CuCr alloy by SHS-metallurgy method

In the preparation of CuCr alloy through SHS-metallurgy method, the Al₂O₃ and Cr₂O₃ inclusions in the alloy can be dissolved by the smelting slag during the slag refining process, thus the composition of the slag is changed, and this further affects the properties of the smelting slag, such as the melting point, viscosity, density and surface tension, which poses a hindrance to the slag refining process. The effects of Al₂O₃ and Cr₂O₃ on the properties of smelting slag were researched in this paper, and the results show that: the increase of Al₂O₃ and Cr₂O₃ content can increase the viscosity, solidification temperature and surface tension of slag; Cr₂O₃ has a significant effect on the viscosity and surface tension of the slag and Al₂O₃, the solidification temperature. Al₂O₃ increases the density of melts, and Cr₂O₃ causes the density of melts to rise first and then decrease.
