Embodiment Construction

[0017] Such as figure 1 As shown, the processing process of the high-precision ultra-thin and extra-wide cold-rolled steel strip in the present invention is as follows: at first getting the hot-rolled strip blank with a thickness of 3 millimeters and a width of 600 millimeters, place the hot-rolled strip blank in 10% hydrochloric acid solution Medium immersion treatment, using hydrochloric acid to remove oxides on the surface of the hot-rolled strip; then the hot-rolled strip treated with hydrochloric acid is passed through a large-diameter four-roll reversing cold rolling mill with high steel strength, large rolling force, and high tension , using the four-roll reversing cold rolling mill to carry out multi-pass rolling of the hot-rolled strip, combining large reduction and small reduction, to obtain high-precision cold rolling with a thickness of 0.25 mm and a width of 600 mm. Rolled steel strip; then the high-precision cold-rolled steel strip is rewinded and degreased, and ...

Abstract

A technology for making high-precision super-thin very-wide cold-rolled steel band and the chrome-plated steel band dedicated as shield of optical cable includes treating the surface of hot-rolled raw band, cold rolling with large-diameter 4-roller reversible cold rolling mill to make its thickness to be 0.1-0.25 mm, recoiling, degreasing, bright annealing, cold rolling again to make its thickness to be 0.06-0.08 mm to obtain said high-precesion steel band, chemical degreasing, washing, electrolytic degreasing, pickling, plating chrome, washing, plating chrome again, washing, baking and coating oil to obtain the said shield of optical cable.

Description

technical field [0001] The invention relates to a high-precision ultra-thin and ultra-wide cold-rolled steel strip and its processing technology, as well as a chrome-plated steel strip specially used for shielding in optical fiber cables by using the high-precision cold-rolled steel strip and its manufacturing technology. Background technique [0002] At present, the ultra-thin steel strip produced at home and abroad is rolled by a multi-roll mill with more than six rolls, and other auxiliary equipment is used to improve its surface flatness, but the ultra-thin cold-rolled steel strip made by the existing process The belt has the disadvantages of high cost, complex manufacturing process and poor shape of the steel strip. [0003] In addition, currently used in optical fiber cables and can play a shielding role is the aluminized film, but the shielding effect is not good when the aluminized film is used for shielding. If a chrome-plated steel strip can be used for shielding,...
