An Online Adjustment Method of Vertical Looper Roll System

Abstract

The invention relates to an online adjusting method of a vertical loop roller system. The technical problem of tin plate surface black ash defects can be solved. Unit shutdown time is used, strip steel in a loop is firstly drawn out, a moving trolley of the loop is fixed in the rolling line direction, a filler gauge is used for correcting the clearance amount between loop side guide wheels, the side guide wheels and a rail, the numerical control is controlled within 2 mm, a datum line introducing method is used for adjusting the mounting precision of a fixed roller and a moving roller of an outlet loop, the precision is controlled within 0.05 mm / m, and levelness crossing cannot appear between the two rollers. After the loop is subjected to threading and when a unit is started up to run, aruler is used for measuring the distances delta x between the strip steel and the two sides of the fixed loop roller, according to the detection result numerical value, the roller perpendicularity delta y is adjusted or according to the detection numerical value, the flatness delta z of the loop moving trolley is adjusted, the loop roller system precision is ensured, and the method is used for vertical loop roller system adjusting during thin plate thin material producing by a cold rolling factory.

Description

technical field [0001] The invention relates to an on-line adjustment method of a vertical looper roll system, which is used for adjusting the vertical looper roll system of thin (0.17mm-0.55mm) tin plate production in a cold rolling mill. Background technique [0002] The tinned products produced by the tinning unit of the cold rolling plant are used to make beverage and food cans, and the black and gray defects on the surface of the tinplate are one of the main quality defects. Black ash is mainly produced in the production process of tinplate. It is a highly dispersed substance. In severe cases, it is brownish-yellow mist and unevenly distributed. When it is wiped on the test paper, it becomes black powder. It not only affects the corrosion resistance and aesthetics of the product, but also seriously affects the binding force between the tin layer and the passivation film, and between the passivation film and the coating, especially after the paint is covered when the bla...
