Problems solved by technology

At present, electromagnetic stirring is widely used in industry, but electromagnetic stirring not only consumes a lot of energy, but also produces bright white bands in the solidification structure of the billet, component segregation, and sometimes ring segregation, which is difficult to solve the center of the billet. Shrinkage cavity and central porosity, and the equipment investment of electromagnetic stirring is also very large

Embodiment Construction

[0013] The basic structure of the continuous casting machine feeding belt stirring equipment is shown in the figure.

[0014] The molten steel in the tundish 1 enters the crystallizer 3 through the nozzle 2 for continuous casting.

[0015] The body 11 is provided with a rotatable strip coil 8 through a bracket, and a vibrator 6 and a driving device 7 are arranged in sequence on the side of the body 11 close to the crystallizer 3. After the metal belt 5 passes through the driving device 7 and the vibrator 6, it is guided The guard is vertically inserted into the molten steel 4 of the crystallizer. The function of the driving device 7 is to move the metal strip to the direction of the crystallizer 3 according to the power provided by the electric control device 9 at a set feeding speed, and has a straightening function. The driving device 7 has a variety of mechanical structures to choose from, such as the structure of upper and lower double driving rollers; the belt feeding sp...

Abstract

A band feeder of conticasting machine for vertically feeding a metallic band into the molten steel in crystallizer is composed of a machine body, a coiled band on a supporting frame, a vibrator, a band driver, and a guider. It features that the metallic band is fed into molten steel at a certain vibration frequency and a certain speed for improving the intrinsic quality of conticast billet.

Description

technical field [0001] The invention belongs to the technical equipment field of continuous steel casting in the metallurgical industry, and in particular relates to belt feeding equipment for a continuous casting machine which directly interferes with the internal quality of a billet. Background technique [0002] The solidification process of molten steel plays an important role in the quality of steel. In the production process of continuous steel casting, the molten steel is rapidly cooled in the crystallizer to form a slab shell first, and the cooling process is from the edge to the inside, and the temperature in the center is high, resulting in a high temperature difference along the section of the slab, and the crystallization process In the middle, internal defects such as element analysis and central porosity are formed in the central area of ​​the slab. Practice has proved that this problem is a typical difficult problem in the continuous casting production proces...
