摘要： In a lubricant composition suitable for use in the manufacture of aluminum alloys comprising a lubricant base, the improvement wherein the lubricant composition further comprises: an effective amount of water, surfactant, and a high viscosity organic material having a low vapor pressure. It is believed that this mixture provides a method for uniformly distributing the surface oxide at the meniscus for casting applications and increasing meniscus stability. Uniform distribution of the oxide and increased stability at the meniscus reduces vertical fold formation that can lead to cracks in the aluminum ingot. In addition, the mixture promotes uniform heat transfer around the mold. Uniform heat transfer around the mold allows the solidifying aluminum alloy to stay in contact with the mold longer and form stronger ingot shells. A process for continuous or semi-continuous casting of aluminum alloys via the use of this lubricant composition is also disclosed.

摘要翻译： 在适用于制造包含润滑剂基底的铝合金的润滑剂组合物中，改进之处在于润滑剂组合物还包含：有效量的水，表面活性剂和具有低蒸气压的高粘度有机材料。 据信该混合物提供了用于在用于浇铸应用的弯月面均匀分布表面氧化物并增加弯液面稳定性的方法。 氧化物的均匀分布和在弯月面的增加的稳定性减少了可能导致铝锭裂纹的垂直折叠形成。 此外，混合物促进模具周围的均匀热传递。 模具周围的均匀传热允许固化铝合金与模具保持更长的接触并形成更强的锭壳。 还公开了通过使用该润滑剂组合物连续或半连续铸造铝合金的方法。
