Abstract
PURPOSE: To contrive the reduction of the cost, and to excellently improve the working efficiency and product quality, etc., by carrying out the shot-blast or the injection of high pressure water including the granules, directly following to the cold rolling work, without removing the scale adhering to the surface of the hot rolled steel strip.
CONSTITUTION: The tip of the rolled steel strip 7 is uncoiled from the uncoiler 1, and is jointed by welding of the welder 2 to the tail end of the preceding hot rolled steel strip 8. The hot rolled steel strip 8 is fed into the cold rolling mill line 4 through the strip storage 3, and is cold rolled at a draft percentage above 40%. The cold rolling mill line 4 can be eithee of the single stand type mill line or the multistand type mill line. Following to the cold rolling work, the scale of the surface of the intermediate rolled strip 9 is perfectly descaled by the shot-blasting device or the injector 5 for high pressure water including granules, and is coiled by the coiler 6. For the granules for use of the shot-blast, either of steel grid, iron sand, etc., is available.
