Description
技术领域
本发明涉及一种具有优异退火清净性的钢冷轧油。
背景技术
随着市场竞争的日趋激烈，冷轧带钢的表面质量占有越来越重要的位置，轧后带钢表面的残留量过多，不但需要消耗下道清洗工序的大量化工原料，而且容易形成油斑等不可逆的表面缺陷，影响退火后板面光洁度。近年来，随着对轧制油及轧制变形区内润滑状况研究的不断深入，轧制油在使用的过程中应尽可能的在轧制变形区形成连续且厚度均匀的油膜，厚度均匀的油膜有利于降低磨损，减小轧制负荷，而且有利于提高轧制后退火带钢表面清净性。具有优异退火清净性的钢冷轧油对于没有清洗线和连退工序的钢铁企业尤为重要。
发明内容
本发明的目的在于根据上述背景技术的现状，提供了一种具有优异退火清净性的钢冷轧油。
为了解决上述技术问题，本发明提供了如下的技术方案：
一种具有优异退火清净性的钢冷轧油，按重量百分比计，包括如下组分：
优选地，所述烷基化氨基苯酚为2,6-二叔丁基-4-(二甲基氨基甲基)苯酚。
本发明的钢冷轧油具有良好的润滑、防锈能力，产品在乳液使用条件下具有良好的清洗效果，保持了轧机的整洁和轧制后钢板的低残油残铁量，减轻轧钢后道工序的清洗和退火压力。且本发明的钢冷轧油在惰性气体氛围中具有较低的挥发温度和较低的碘值，使得产品在退火炉升温阶段已经大量挥发完成，降低了轧制油在高温条件下氧化高聚及碳化的可能性(带钢表面会有少量的空气夹带，导致退火炉中会有极少量氧气的存在可能)，保证了退火后的清净性。
附图说明
附图用来提供对本发明的进一步理解，并且构成说明书的一部分，与本发明的实施例一起用于解释本发明，并不构成对本发明的限制。在附图中：
图1为本发明钢冷轧油与市售钢冷轧油产品的falex扭矩对比。
图2为本发明钢冷轧油与市售钢冷轧油产品的falex不同扭矩条件下磨损温度的对比。
图3为本发明钢冷轧油与市售钢冷轧油产品在氮气氛围铁盘条件下的TGA曲线对比。
图4为采用本发明钢冷轧油与市售钢冷轧油产品轧制后，带钢在罩式退火炉中的退火结果对比。
具体实施方式
以下结合附图对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
