Arc alignment device for foot roller of continuous casting machine

Abstract

According to an arc alignment device for a foot roller of a continuous casting machine, an arc alignment sample plate is composed of an inner arc plate, an outer arc plate and a straight face arc plate which are welded in a crossed mode, an inner arc alignment working face and an outer arc alignment working face are arranged on the lower portions of the inner arc plate and the outer arc plate, anda straight face arc alignment working face is arranged on the lower portion of the straight face arc plate; the upper portions of the inner arc plate, the outer arc plate and the straight face arc plate are provided with adjusting screws located in corresponding plate faces respectively and are provided with locking nuts in an assembled mode, the upper end of the arc alignment sample plate is coaxially connected with square steel, and supporting rods are orthogonally connected to the four side faces of the square steel respectively; and a guide plate is arranged above a crystallizer upper flange, the guide plate is provided with a cross-shaped guide hole with a central round opening, locating pins used for being fixedly connected with the crystallizer upper flange are arranged below the guide plate, the square steel penetrates through the cross-shaped guide hole, and the supporting rods are located above the guide plate. The device is used for arc alignment of the foot roller of the continuous casting machine, arc alignment operation is facilitated, time and labor are saved, the arc alignment work efficiency and arc alignment precision can be greatly improved, and meanwhile the application performance of the arc alignment sample plate is improved.

Description

technical field [0001] The invention relates to a calibrating device for a continuous casting machine, in particular to an arc alignment device for foot rolls of a continuous casting machine. Background technique [0002] The mold is the most critical component in the continuous casting machine. Before using the crystallizer, align the foot roller with the copper tube of the crystallizer. The existing technology adopts single-piece, double-piece or frame-type alignment templates, which need to be held or used to position the alignment templates to measure the arcs. The work efficiency is low, the operation is inconvenient, and the accuracy of the alignment is affected. At the same time, since the arc-aligning template is a stereotyped structure, one arc-aligning template is only suitable for mold copper tubes with one taper, and its applicability is poor. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a f...
