Embodiment 1

[0082] Embodiment 1—The vibrating part hits the support roller through the vibrating box, and the gas path structure with a reversing valve

[0083] Such as figure 1 As shown, a continuous casting rotary support roll with vibrating parts includes: supporting roll body 1, end covers 2 on both sides of the roll body, bearing housing 3, bearing 4, support shaft 5, vibration box 6, vibrating parts 7. Shaft end seat 8, elastic support seat with guiding device 9, elastic body 10, base frame 11, first air intake channel 12, second air intake channel 13, upper air intake hole 14, lower air intake hole 15, air outlet Matching hole 20 , air outlet channel 21 of inner and upper cavity, air outlet channel 22 of inner and lower cavity, outer air outlet channel 16 and reversing valve 17 . Structurally, the support roller body 1 is connected with the end covers 2 on both sides of the roller body by means of bolts and pins to facilitate disassembly and maintenance. The support shaft 5 and...

Embodiment 2

[0087] Embodiment 2—The vibrating member directly hits the support roller, and the gas path structure with a reversing valve

[0088] One end of the vibrating member 7 can be exposed from the vibrating box 6, and strikes against the inner wall of the supporting roller body 1 to generate vibration. Also vibration box body 6 can be made to close, see figure 2 , the vibrating member 7 performs reciprocating periodic vibration in the vibration box 6, and knocks the front and rear end covers of the vibration box 6 to generate vibration force.

Embodiment 3

[0089] Embodiment 3—The elastic part of the continuous casting rotary support roll is a structure of leaf spring

[0090] see image 3 , the elastic member of the continuous casting rotary support roll may also be a structure of a leaf spring 19 arranged under the entire support roll.

Abstract

The invention relates to a rotary supporting roller provided with a vibrating part. The rotary supporting roller comprises a supporting roller body (1), a supporting shaft (5), a shaft end base (8) and a base body rack (11), wherein the rotary supporting roller comprises at least one vibrating unit and an elastic supporting base (9); the vibrating unit comprises a vibrating box body (6) and the vibrating part (7); the vibrating box body (6) is of a hollow structure and is arranged inside the supporting roller body (1); the vibrating part (7) is driven by a fluid power source so as to do reciprocating motion along the inner wall of the vibrating box body (6); and the vibrating part (7) can make a blank housing of a casting blank (18) be stressed and generate vibration perpendicular to the surface of the casting blank by virtue of a protruding vibrating head. The rotary supporting roller provided by the invention realizes grain refinement of a continuous casting blank and effectively improves the quality of the continuous casting blank.

Description

technical field [0001] The invention belongs to the technical field of metal solidification and continuous casting, and in particular relates to a continuous casting rotary support roll with vibrating parts. Background technique [0002] With the development of metallurgical technology in the world, modern continuous casting technology continues to improve, and the types of castable steel continue to expand. Some high-alloy, high-quality special steels have been continuously produced in the continuous casting production process of large iron and steel enterprises. In order to solve the above problems, metallurgical scientific and technological workers have developed many patents and technologies in this technology for a long time. At present, there are mainly electromagnetic stirring technology and soft pressing or casting and rolling technology at the end of solidification that are widely used in industrial production. [0003] The application of electromagnetic stirrer is...
