Embodiment 1

[0072] Example 1: see figure 1 , an on-line accurate measurement method for continuous casting slab width, the method comprises the following steps:

[0073] Step 1: Installation of the slab width information collection device;

[0074] 1.1 Install a laser range finder and a set of photocells for detecting the position information of the slab on both sides of the slab delivery conveyor (see the layout method). figure 1 ).

[0075] 1.1.1 Two laser rangefinders are arranged on the east and west sides of the roller table respectively, and are arranged horizontally (perpendicular to the center line of the billet roller table, equidistant) in the opposite way;

[0076] 1.1.2 In order to realize the automatic calibration of the equipment, the two rangefinders are misaligned by 40mm-60mm in the north-south direction.

[0077] 1.1.3 In order to prevent the high temperature radiation of the slab from interfering with the measurement accuracy, two rangefinders are set up to measure t...

specific Embodiment

[0129] Specific embodiment: refer to figure 1 — Image 6 , Slab continuous casting in a steel plant, the minimum width of the slab is 880mm, the maximum width is 1700mm, and the thickness of the slab is 230mm. In order to realize the accurate measurement of the slab width online and provide accurate information for the subsequent rolling, the technology provided by the method of the present invention is used. Process, its specific implementation is as follows:

[0130] An online accurate measurement system for continuous casting slab width

[0131] Step 1. Installation of slab width information collection device;

[0132] 1.1 Install a laser range finder and a set of photocells for detecting the position information of the slab on both sides of the slab delivery conveyor (see the layout method). figure 1 ).

[0133] 1.1.1 Two laser rangefinders are arranged on the east and west sides of the roller table respectively, and are arranged horizontally (perpendicular to the cent...

Abstract

The invention relates to an online accurate measurement method for the width of a continuous casting slab. The method comprises the following steps: step 1, mounting a slab width information acquisition device; 2, plate blank width data are collected; step 3, uploading width data of the plate blank; step 4, performing abnormal treatment on the width measurement data of the plate blank; 5, plate blank width data information processing; and 6, completing the online measurement and correction process of the width of the plate blank. According to the scheme, a width detection component, a communication system and a correction model are included, and multiple automatic functions such as slab online width real-time detection, information transmission, width correction and width abnormity alarm are achieved.

Description

technical field [0001] The invention relates to a measurement method, in particular to an online accurate measurement method for the width of a continuous casting slab, belonging to the technical field of iron and steel metallurgy continuous casting. Background technique [0002] As a product produced by a continuous caster, the continuous casting slab is the raw material for hot rolling. The specification information of the slab is a main content of the information transmission between the processes in the slab logistics, and the slab width is an important production control parameter in the rolling production process. Slab width refers to the final width value of the slab after cooling. The slab width specification information includes three information values: head width, tail width and information width. Because there is no width measuring device in the streamline equipment after cutting, the slab width value is derived from the casting tracking value according to the s...
