Assembling method for inner arc frame and outer arc frame of slab continuous casting fan-shaped section

Abstract

The invention discloses an assembling method for an inner arc frame and an outer arc frame of a slab continuous casting fan-shaped section. The assembling method comprises the steps that 1, a robot isadopted for batch surfacing of seat blocks; 2, a plurality of second marks are arranged on a welding platform in the length direction of a main board according to the positions of limiting parts andthe actual welding positions of the seat blocks and the main board, a first positioning component used for positioning the seat blocks is fixed to each second mark, and a first cushion block used forsupporting the main board to form an interval space between the main board and the welding platform is fixed on the welding platform; 3, the main board is placed on the first cushion block, the main board is adjusted to enable the wide edge of the main board to abut against a limiting component, and after the main board abuts against the first positioning components and the seat blocks, the main board and the seat blocks are welded; and 4, the main board is placed on second positioning components, a head frame is placed on a second cushion block, and the head frame and the main board are welded. The method has the advantages that the welding assembly technological process is simplified, the assembly efficiency is improved, and the pre-welding assembly precision is improved.

Description

technical field [0001] The invention relates to an assembly method of the inner and outer arc frames of the slab continuous casting segment. Background technique [0002] The slab segment frame is an important part of the continuous casting equipment. It is installed behind the mold of the continuous casting machine and is a key component of the continuous casting machine that supports and guides the slab during solidification. In the middle, the slab is cooled to assist in the forming of the slab. The whole set of fan section is divided into bending section, arc section, straightening section and horizontal section, and each fan section is divided into inner arc frame, outer arc frame and pinch roller frame. The structural characteristics of the inner and outer arc frames of the sector are: usually composed of 2 head frames with shaft heads and 6-8 main boards supported in the middle of the head frames. The main boards have specific angles, and each main board usually has ...

AI Technical Summary

Problems solved by technology

[0004] 1. Head frame welding, main board and head welding, seat block welding, seat block butt welding need to be carried out step by step, and the welding cycle is longer;

[0005] 2. Due to the large number of blocks and the distribution on different main boards, when welding the block and the main board, it needs to be turned over and welded many times, and the welding space is narrow, so the working hours are long, the welding process efficiency is low, and the welding process is difficult. Seam quality is not easy to guarantee;

[0006] 3. Since the processing of the surfacing surface on the seat block is carried out after the assembly and welding of the sector frame is completed, the machining of the surfacing surface on the seat block needs to be carried out on a large machine tool, which is time-consuming and costly;

[0007] 4. Due to the large volume of the main board and the head frame after welding, in the prior art, the surfacing welding on the block is carried out manually, and the surfacing welding efficiency is low and the quality is not stable.
