Problems solved by technology

Due to the inconsistent damage of each mating surface, there are many liners with different thicknesses and sizes, which is inconvenient for production and use. Moreover, when the number of processing is too many, it will affect the strength and rigidity of the frame archway.
Second, repair welding machine addition: After the mating surface is surfacing, machining is performed to restore accuracy. The choice of materials and processes is relatively simple. The repaired mating surface will wear again under impact and corrosion, which cannot fundamentally solve the wear problem.
[0005] The threaded hole is repaired by the following methods: 1. Tapping the threaded hole is simple; 2. Fill the threaded hole with electric welding, and then drill and tap. This method generally uses ordinary carbon steel that is soft and easy to drill. The filling of the welding material is consistent with the mechanical properties of the base material. For short-term use, if it is filled with high-strength welding materials, it will be difficult to complete drilling and tapping on site,

Abstract

The invention discloses a detection device for a matching surface of a bending roller cylinder of a plate and strip rolling mill. The detection device comprises reference plates, a Y-axis ruler, an X-axis ruler and a Z-axis ruler; the reference plates comprise a first reference plate and a second reference plate, and the first reference plate and the second reference plate are arranged in parallel. The Y-axis ruler comprise a first Y-axis ruler and a second Y-axis ruler, the first Y-axis ruler is fixed on the first reference plate and is parallel to the first reference plate, and the second Y-axis ruler is fixed on the second reference plate and is parallel to the second reference plate; one end of the X-axis ruler is connected with the first Y-axis ruler, the other end of the X-axis ruleris connected with the second Y-axis ruler, and the X-axis ruler can slide along the first Y-axis ruler and the second Y-axis ruler; and the Z-axis ruler is arranged on the X-axis ruler and can slidealong the X-axis ruler. The invention further discloses a method for detecting and repairing the matching surface of the roll bending cylinder of the plate and strip mill. By detecting the matching surfaces, the damage amount of each matching surface is obtained, and a basis is provided for repairing.

Description

technical field [0001] The invention relates to the technical field of material restoration, in particular to a detection and repair method and detection device for the mating surface of a bending roll cylinder of a strip rolling mill. Background technique [0002] The roll bending cylinder is fixed on the frame archway of the strip mill to control the roll profile of the work rolls of the strip mill to ensure the shape and accuracy of the rolled plate. There are matching surfaces corresponding to multiple spatial positions of the bending cylinder on the frame archway, which has a complex structure and high precision requirements. Due to the severe vibration impact and variable load during rolling, after a certain period of work, the matching surfaces and threaded holes will The wear gradually increases and the accuracy is lost, which affects the stability of the steel rolling operation and affects the product quality and safe production. [0003] Due to the long-term humid...
