Embodiment Construction

[0051] An improved method for stretching and straightening of cold-rolled pickled strip steel, which utilizes a stretching leveler to complete the stretching and straightening work, is characterized in that it comprises the following steps:

[0052] (1) if Figure 6 As shown, the upper work roll 301 and the lower work roll 302 of the stretch leveler 3 are changed from flat rolls to tapered rolls. The diameters of the two ends of the work rolls are 80mm at one end and 78mm at the other end. The spiral effect is applied to ensure that the work rolls The horizontal movement is smooth, and the upper and lower work rolls of the same unit are arranged with the big or small ends facing each other. This arrangement is for the balance of the force on the strip 1 and the work rolls during production; the big ends of the upper and lower work rolls of the 1# unit The small heads of the upper and lower work rolls of unit 2# are opposite to each other. This arrangement is to ensure that the...

Abstract

The invention relates to the field of cold rolling and pickling processes, in particular to an improved method for stretching straightening of strip steel cold rolling and pickling. According to the method, an existing stretching straightener is improved to enable an upper roller and a lower roller to reciprocate in the width direction of strip steel when the strip steel runs, so that the edge of the strip steel passes through all parts within the effective length of the rollers. Therefore, uniform abrasion of a working roll is achieved, the problem of concentrated abrasion is solved, the problems of insufficient acid pickling and plate shape defects caused by non-uniform extension are solved, the online service life of a straightening roll is prolonged, and the problem of high consumption of the roll caused by concentrated abrasion is solved.

Description

technical field [0001] The invention relates to the field of cold-rolled pickling technology, in particular to an improved method for stretching and straightening cold-rolled pickled strip steel. Background technique [0002] In the pickling process of cold-rolled strip production, the principle of reaction between hydrochloric acid and iron oxide is used to remove the oxide scale on the surface of the hot-rolled strip, so that the strip enters the cold-rolling mill with a silver-white iron matrix surface for rolling. Modern cold-rolled In the production of strip steel, the hot-rolled strip steel before entering the pickling tank is descaled by stretching and leveling machine, as shown in the attached figure 1 As shown, it shows the positional relationship between the stretch leveler and the pickling tank in the pickling process. The function of the stretch leveler is first to break the scale, so that many fine cracks are formed on the iron oxide scale on the surface of the...
