    • The present invention relates to a lubricant for use in the drawing and ironing of black plate steel during the manufacture of enclosed containers such as cans. In particular, the lubricant is applied to that portion of the black plate steel which ultimately becomes the outside surface of the can body. The lubricant comprises an aqueous solution of an active component, such as a major portion of molybdenum disulfide, together with minor amounts of waxes and other materials.In performing the method of the present invention, a lubricant system is employed. The lubricant system comprises a dual lubricant coating. The first, or outside, coating is applied to that portion of the black plate steel which ultimately becomes the outside surface of the can body. The outside coating is applied, such as by spraying or gravure or offset printing, at a rate of about 25 to about 200 milligrams per squre foot of steel surface. This coating is dried, as through the use of a heat source, such as infrared heat or hot air. A second, or inside, coating is applied to that portion of the black plate steel which ultimately becomes the inside surface of the can body. The inside coating may also be applied to the surface of the black plate steel in a manner similar to that used for the application of the outside coating. After the can body is produced, the outside and inside lubricants must be totally removed. Such removal may be achieved by washing the can bodies in an alkaline solution (pH about 7.5 to 11.5) having a temperature of about 140.degree. to about 160.degree. F.
    • 本发明涉及一种用于在制造封闭容器(如罐)期间黑板钢的拉丝和熨烫的润滑剂。 特别地,润滑剂被施加到最终变成罐体的外表面的黑色钢板的那部分。 润滑剂包括活性组分的水溶液,例如主要部分的二硫化钼,以及少量的蜡和其它材料。 在执行本发明的方法时,采用润滑剂系统。 润滑剂系统包括双润滑剂涂层。 将第一或外部的涂层施加到最终变成罐体的外表面的黑色钢板的那部分。 以每平方英尺的钢表面约25至约200毫克的速率施加外部涂层,例如通过喷涂或凹版印刷或胶版印刷。 通过使用诸如红外热或热空气的热源干燥该涂层。 第二或内部的涂层被施加到最终变成罐体的内表面的黑色钢板的那部分。 内部涂层也可以以与用于外涂层的方式类似的方式施加到黑色钢板的表面上。 罐体生产后,外部和内部润滑剂必须完全除去。 这种去除可以通过在温度为约140°至约160°F的碱性溶液(pH约7.5至11.5)中洗涤罐体来实现。
