Problems solved by technology

In use, it is found that the long arc plate type needs to align the arc plate to all the rollers in the entire bending section when aligning the arc. The disadvantage is that the arc plate is long and easy to deform, resulting in a decrease in accuracy. Aligning so many rollers at the same time requires personnel to enter the bending section. Arc alignment operation is not only dangerous but also time-consuming
The arc alignment device of the horizontal ceremony only aligns one roller in the crystallizer and the bending section, and the arc alignment is measured by the perpendicularity of two points. The disadvantage is that any garbage or depression on the rollers will cause extreme arc alignment. Large error, the measurement also requires personnel to enter the bending section to clean the rollers to ensure the measurement accuracy, and the safety of the operation is not good

Embodiment Construction

[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Please combine Figure 1 to Figure 3 As shown, the arc alignment device between the crystallizer and the bending section of the continuous casting machine provided by the present invention includes several pairs of rollers 2 arranged on both sides of the bending section 1, and also includes an arc alignment support 3 and an arc alignment plate 4.

[0031] Preferably, the arc-aligning support 3 is arranged between the rollers 2 on both sides of the bending section 1, and includes a bottom plate 301, a bevel 302 and a bottom plate positioning support plate 303. The bottom plate 301 is arranged in a rectangular shape, and in the longitudinal direction of the bottom plate 301 At the center position of the arc plate 4, a guide positioning groove 304 is cut out for the passage of the arc plate 4. The length of the guide posi...

Abstract

The invention discloses an arc-aligning device and an arc-aligning method used between a crystallizer and a bending section of a continuous casting machine. The arc-aligning device comprises multiplepairs of rollers arranged on the two sides of the bending section, and further comprises an arc-aligning support and an arc-aligning plate; the arc-aligning support is arranged among the rollers at the two sides of the bending section, the arc-aligning support comprises a bottom plate, inclined wedges and a bottom plate positioning backup plate, the bottom plate is arranged to be in a rectangularshape, a guide positioning groove for allowing the arc-aligning plate to penetrate through is formed in the longitudinal central position of the bottom plate, a pair of inclined wedges are arranged and are symmetrically arranged at the parts, on two sides of the guide positioning groove, of the upper surface of the bottom plate, a plurality of hoisting holes are formed in the bottom plate, and thebottom plate positioning backup plate is arranged at the rear end of the lower surface of the bottom plate; and the arc-aligning plate is arranged to be in a rectangular strip shape, a hoisting holeis formed in the upper end of the arc-aligning plate, and a pair of symmetrical arc plate supporting shafts are further connected to the two side faces of the arc-aligning plate. According to the arc-aligning device and the arc-aligning method, during arc-aligning operation, a person does not need to enter the bending section, meanwhile, the arc plate can be automatically attached to the surface of the roller needing to be measured, the operation efficiency is improved, and the arc-aligning operation of straight and bent sections can be safely and quickly carried out.

Description

technical field [0001] The invention relates to the field of straight and curved continuous casting machines, and more specifically relates to an arc alignment device and an arc alignment method used between a crystallizer and a bending section of a continuous casting machine. Background technique [0002] The continuous casting machine for continuous steel casting is mainly straight and curved. The straight and curved continuous casting machine is mainly composed of three parts: mold, bending section and fan section. The alignment accuracy between these three parts is very important, especially the alignment between the mold and the bending section, which has a decisive impact on the quality of the continuous casting slab. [0003] When the mold and the bending section are installed on the casting machine, and after casting for a certain period of time or related quality problems occur, it is necessary to measure and adjust the alignment between the mold and the outer arc r...
