为了更好地了解轻质Al2O3-MgO浇注料在炼钢过程中的动态炉渣/耐火相互作用，并避免离心力的影响，将测试棒以不同的转速浸入炉渣中。结果表明，溶解是由Al2O3反应物质通过界面处的炉渣的传输控制的。无论转速如何，轻质 Al2O3-MgO 浇注料的腐蚀速率几乎与传统 Al-2 O-3-MgO 浇注料相同。因此，可以制造出重量更轻的精炼钢包，并保持与普通浇注料相同的使用寿命。 (C) 2015 Elsevier Ltd 和 Techna Group S.r.l.版权所有。
In order to better understand the dynamic slag/refractory interaction of a lightweight Al2O3-MgO castable during steel refining and to avoid the effect of centrifugal force, test bars were immersed in slag at different rotation rates. The results showed that the dissolution was governed by the transport of reaction species of Al2O3 through the slag at the interface. The corrosion rate of the lightweight Al2O3-MgO castable remained almost the same as that of conventional Al-2 O-3-MgO castables, regardless of rotation speed. Thus a refining ladle can be fabricated that weighs less and retains the same lifetime as common castables. (C) 2015 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
