Embodiment Construction
[0011] Such as figure 1 Shown: the rolling mill installation control measuring net of the present invention puts the method for setting, and it comprises:
[0012] Step 1: From the continuous rolling mill to the transverse center line and based on the F4 rolling mill, measure the transverse center of the rolling mill respectively, and make a straight line parallel to the rolling line at the position of ±0 on the transmission side of the rolling mill, 5m away from the rolling line;
[0013] Step 2, place the instrument at control point 1, measure 90° with control 2 as the backsight, place it 5m along the side of 90°, and place the instrument on control point 2 after determining point 1′, with point 1 as the The rear view side is 90°, and point 2' is placed along the 90° side, so that there are two points 1' and 2', and through these two points, an auxiliary line parallel to the rolling line is formed. This straight line is parallel to passing through 1, 2 a straight line betwe...

Abstract
The invention relates to installation of a rolling mill, and discloses a rolling mill installation control measuring net placing method. The method comprises the following steps that transverse centers of rolling mills are measured correspondingly according to transverse center lines of the continuous rolling mills by taking the rolling mill F4 as a basis, and a straight line parallel to a rollingline is made at a position away from a rolling line by 5 meters and at the rolling mill transmission side + / - 0 positions; an instrument is arranged at a control point 1, 90 degrees are measured by taking a control point 2 as the back vision, 5 meters are set along the 90-degree edge, a point 1' is determined, then the instrument is placed on the control point 2, 90 degrees are measured by takingpoint 1 as the back vision, a point 2' is set along the 90-degree edge, and then an auxiliary line parallel to the rolling line is formed through the point 1' and the point 2'; the instrument is arranged at the intersection point of the auxiliary line and the rolling mill F4 for 90-degree measurement; after the transverse line of the rolling mill F4 is determined, the instrument is used for orientation on the auxiliary line, measuring points of the transverse center line of each rolling mill are measured along the orientation line, then the instrument is placed on each point, and the transverse line of each rolling mill is determined in sequence. According to the method, the investment of labor force is reduced, the working efficiency is improved, and the potential safety hazard is reduced.
Description
technical field [0001] The invention relates to the installation of a rolling mill, in particular to the placement of a rolling mill installation control measuring net. Background technique [0002] Rolling mill is one of the main production equipment of metallurgical enterprises, and its installation quality is an important guarantee for the quality of rolled steel produced in the future. Usually a metallurgical enterprise has more than one rolling mill, and more than five has become the norm. The quality of its installation is especially important. Taking the 1780 hot rolling mill as an example, its transverse centerline is 5.8m. If there are seven rolling mills, the total length of the foundation can reach 40m. The length of the transverse centerline of the rolling mills to be measured is more than 50 meters. Since the longitudinal center of the rolling mill is 90°, the instrument must be placed at the intersection of the longitudinal line and the transverse center. How...
