    • In accordance with the present invention there is provided an additive for cold rolling lubricants which improves the lubricity, as well as the cooling properties, of the lubricant. According to the present invention, a polar liquid with a boiling point between 25°C and 500°C may function as an additive for cold rolling lubricants. The additive is added to a typical cold rolling lubricant such as an oil comprising of 5-10 percent fatty alcohol and 1-2 percent fatty ester in a hydrocarbon oil. The additive is added to the rolling lubricant in the proportions of about 0.1 to 10 percent, preferably about 1 to 4 percent and more preferably about 1 to about 3 percent. The additive of the present invention lowers friction at higher rolling speeds and metal reductions and exhibits an improved cooling ability. Optionally, a small amount of water may be added to the additive/lubricant composition to further increase the composition’s cooling ability. In one aspect of the present invention the additive/lubricant may also contain less than 1 percent corrosion inhibitor.
    • 根据本发明,提供一种用于冷轧润滑剂的添加剂,其提高润滑剂的润滑性以及冷却性能。 根据本发明,沸点在25℃和500℃之间的极性液体可用作冷轧润滑剂的添加剂。 将添加剂加入到典型的冷轧润滑剂中,例如在烃油中包含5-10%脂肪醇和1-2%脂肪酯的油。 添加剂以约0.1至10%,优选约1至4%,更优选约1至约3%的比例加入到滚动润滑剂中。 本发明的添加剂在较高的轧制速度和金属减少的情况下降低了摩擦,并表现出改善的冷却能力。 任选地,可以向添加剂/润滑剂组合物中加入少量的水以进一步提高组合物的冷却能力。 在本发明的一个方面,添加剂/润滑剂还可含有少于1%的腐蚀抑制剂。
