Arc alignment device for mold and arc alignment method

Abstract

The invention provides an arc alignment device for a mold and an arc alignment method. The arc alignment device for the mold comprises a supporting frame. The supporting frame is provided with oscillation guide centering devices, an arc alignment reference block and an offline arc alignment sample plate locating piece, wherein the oscillation guide centering devices are used for simulating a mold oscillation guide device, the arc alignment reference block is used for simulating the position of an outer arc reference surface of the mold, and the offline arc alignment sample plate locating piece is used for simulating the centering and fixing positions of an offline arc alignment sample plate of a mold centering platform. By the adoption of the arc alignment device for the mold and the arc alignment method, during arc alignment, the offline centering platform can be adjusted and fixed offline, and then a copper plate and a foot roll of the mold are centered uniformly and offline; an outer arc roller of a supporting and guiding section can be detected online, and mold oscillation guide wheels of the supporting and guiding section can be uniformly adjusted offline; and hence, automatic arc joint is achieved after the mold is in position, and exchange of the molds of all the strands of a multi-strand casting machine is achieved.

Description

technical field [0001] The invention belongs to the technical field of continuous casting machine maintenance, and in particular relates to an arc aligning device and an arc aligning method for a crystallizer. Background technique [0002] The mold is the heart of the continuous casting machine. Its installation accuracy directly affects the quality of the slab, and its alignment accuracy is an important factor affecting the surface quality of the slab. If the deviation of the alignment exceeds the limit, it will lead to serious production safety such as breakout. Accidents happen. [0003] For multi-machine and multi-strand slab continuous casting machines, the mold is arranged in an inner and outer arc. Generally, the arc alignment method of the mold is that the mold first goes online after the arc alignment is completed on the offline centering station, and then uses the arc alignment template to align the arc online, and detects the arc.

[0002] The mold is the heart of the continuous casting machine. Its installation accuracy directly affects the quality of the slab, and its alignment accuracy is an important factor affecting the surface quality of the slab. If the deviation of the alignment exceeds the limit, it will lead to serious production safety such as breakout. accident happened

[0003] For multi-machine and multi-strand slab continuous casting machines, the mold is arranged in an inner and outer arc. Generally, the arc alignment method of the mold is that the mold first goes online after the arc alignment is completed on the offline centering station, and then uses the arc alignment template to align the arc online, and detects the arc. The contact arc between the crystallizer and the support and guide section, but due to the unavoidable large off-line measurement error and equipment deformation in the production process, there is usually a deviation between the foot roller of the crystallizer and the support and guide section roller after going online. Larger need for online secondary adjustment

[0004] The problem with this adjustment method is that the workload is large and the working time is long. After the second adjustment on-line, the copper plate and the foot roller of each flow crystallizer are not in the same position as the reference. Crystallizer repair and maintenance cause great difficulties
