LIGHT-GAGE COMPOSITE-COATED FLAT-ROLLED STEEL MANUFACTURE AND PRODUCT |
摘要 |
<p>New composite-coated flat-rolled steel products and new methods of manufacture in which low carbon steel (16), as received in cold-reduced continuous strip form is prepared for plating; a corrosion prevention plating (24) is applied, and a polymeric coating with lubricant (26) is applied as a finish surface. The resulting composite-coated steel substrate is cold-rolled (36) to decrease the gage of the coated substrate. Optionally, cold-rolling steps (14) and/or stress relief heat treatment steps (10,20) may be employed prior to surface treatment. This process provides for tin mill manufacture of composite-coated steel of various weights per unit area, for example, in the range of 35 to about 100 lb/bb, useful in the manufacture of can bodies.</p> |
