Abstract

A mill centering device for a finishing mill group is characterized by comprising a laser pen, a fixing seat, a position measuring rod and a positioning ring, the fixing seat for fixing the laser pen comprises an upper plate, a lower plate and a pen holder arranged on the lower plate, the upper plate is arranged on the pen holder, the laser pen is tightly clamped between the upper plate and the lower plate, the position measuring rod is a cylindrical rod, a sign board is arranged on the end face of the position measuring rod, a central hole is arranged on the sign board, the sign board is coaxial with the position measuring rod, the positioning ring is a circular ring, an arc groove is arranged on the outer wall of the circular ring, x-axis and y-axis coordinate signs are marked on the sign board, and the central hole on the sign board is a coordinate origin. The mill centering device is applied to detecting the deviation distance from the central line of a mill and a guide seat to a rolling line, the mill and the guide seat are adjusted according to the measured deviation distance so that the central line is overlapped with the rolling line, and the mill centering device solves the problem that a high speed wire rod mill only has a single frame guide for centering while having no centering method and device for mills of a whole finishing mill group and a guide seat.

Description

Mm finishing mill unit milling train centralising device

Technical field

The utility model belongs to the production auxiliary equipment of metallurgical production enterprise, is specifically related to a kind of mm finishing mill unit milling train centralising device.

Background technology

[0002] the finishing wire unit of smelter puts operation into production for many years, and finishing mill has the phenomenon that departs from roll line; But do not have detection means accurately, cause finishing mill frequently to pile steel, fault time is many; Percent defective is high, and the finishing mill spring leaf is disconnected repeatly more than, causes the finished size shakiness, both wastes energy; Increase cost again, also increased the stopping production handling failure time.

Summary of the invention

In order to enhance productivity, reduce the rolling mill fault rate, improve the product size precision, the utility model provides mm finishing mill unit milling train centralising device.

The utility model is made up of holder, location rod and the locating ring of laser pen, fixed laser pen, and the holder of fixed laser pen is made up of upper plate, lower plate and pen stand, and pen stand is arranged between lower plate and the upper plate; Laser pen is arranged on the pen stand, and the location rod is a cylindrical bar, and the end face of location rod is provided with sign board; Sign board is provided with centre bore; Sign board and location rod coaxial line, locating ring is a circular rings, the outer wall of circular rings is provided with arc groove.

Described sign board is marked with x axle and y axial coordinate sign, and the centre bore on the sign board is the origin of coordinates.

The method for using of the utility model is: the lower plate of the holder of fixed laser pen is fixedly mounted on the mm finishing mill unit first rolling mill entrance side leads on the seat of position; Locating ring tightly overlaps (interference fit) on the roll neck that is positioned at frame side of the roll of each tested milling train; The location rod is arranged in the arc groove on the locating ring of last rolling mill of mm finishing mill unit, and the light beam that laser pen sends projects on the sign board of location rod.

Keep the laser pen light source direction of first rolling mill constant, according to the method described above each rolling mill is measured, read the coordinate distance that departs from of each milling train and light source respectively, the distance that departs from is exactly the distance that milling train departs from roll line.Installation site according to the distance adjustment milling train that departs from.

The utility model is applied to detect milling train and leads position seat center line and roll line deviation distance; Adjust milling train and lead the position seat through the deviation distance of measuring; Center line is overlapped with roll line; Its high-speed rod-rolling mill that is through with has only single frame to lead a centering for a long time, does not have whole mm finishing mill unit milling train and the centering method and the device of leading the position seat.

The utility model made an experiment in the stainless wire rolling plants of Shanxi Taigang Stainless Steel Co., Ltd in 2010, and 19 of finishing mills are 2mm on the lower side; 21 rolling mills are 2.5mm on the lower side, the 2mm that takes back, and through the finishing mill installation site is adjusted, ten finishing mill center lines all overlap with rolling centerline fully.At least prolonged 2 times the service life of spring leaf, year has been reduced by 130 tons in waste product, has reduced the handling failure number of times effectively.
