A method for installing a continuous casting crystallizer

Abstract

The invention relates to a method for installing a continuous casting crystallizer, and belongs to the field of installation construction of steel making equipment. The method is characterized in thatthe embedded part is accurately positioned in the construction process of civil engineering, the installation precision of the embedded part is ensured, and the offline detection and on-line installation of the crystallizer are realized, so that the whole installation effect of the crystallizer is guaranteed; in the installation process of the crystallizer, installation of the embedded part is carried out firstly, and the embedded part is installed by the aid of the tool support, after the concrete is poured, secondary grinding is carried out on the embedded part, and the combination of the crystallizer vibrating table and the embedded part is guaranteed; the online accuracy of the crystallizer is ensured through off-line detection of the crystallizer, the crystallizer only needs to be installed on line without secondary verification; the method for installing a continuous casting crystallizer comprises the following construction steps of 1, matching the civil engineering, burying theembedded part of the crystallizer vibration device; 2, installing a bottom plate of a crystallizer vibration device; 3, installing a crystallizer vibration table; 4, installing a crystallizer and a crystallizer cover; 5, installing air, water and a hydraulic medium pipeline, so that the installation progress is improved, the precision is improved, and the cost is reduced.

Description

technical field [0001] The invention belongs to an installation and construction method of steelmaking equipment, and in particular relates to an installation method of a continuous casting machine. Background technique [0002] Continuous steel casting is cast through the ladle rotary table through the crystallizer to the fan-shaped section of the continuous casting secondary cooling section. The mold is the heart of the continuous casting machine. The molten steel is initially condensed into the shape of the billet in the mold to form a certain thickness. The slab shell is continuously pulled out from the lower mouth of the crystallizer and enters the secondary cooling zone; its function is to ensure the thickness of the slab shell at the highest possible pulling speed to prevent leakage, so that The molten steel solidifies rapidly, so the wall of the crystallizer should have good thermal conductivity, water cooling conditions, non-bonding of the inner wall and sufficient ...

AI Technical Summary

Problems solved by technology

[0003] The mold is mainly composed of the embedded parts of the crystallizer vibrating table, the mold vibrating table, the mold and the cover plate. The mold is matched with the fan-shaped section and connected with the subsequent fan-shaped section to form a whole. The mold controls the formation of molten steel. The mold is installed in a narrow environment, and the connection and installation quality of the installation process of the embedded parts and the vibrating table directly affect the normal production of continuous casting. How to ensure fast, Efficient installation is the focus of mold construction and installation control; at present, the general continuous casting mold is installed in a top-down manner, that is, the embedded parts are welded on the embedded plate of the civil structure, and then the mold is installed. The installation of the crystallizer vibration device bottom plate and embedded parts, crystallizer vibration table does not perform offline calibration, there are problems that the crystallizer vibration device bottom plate cannot effectively connect the upper and lower processes, and frequent crossover, repeated operations, and low efficiency; The installation method of the continuous casting crystallizer has been searched in the Chinese national patent data, and no relevant information has been retrieved yet.
