Embodiment Construction

[0027] figure 1 Among them, the vibration support roll device is composed of a vibration support roll 1 that is closely attached to the four walls of the continuous casting slab, and a vibration transmission pipeline 2 and a vibration generation source 3 connected to it.

[0028] figure 2 In this process, the vibrating support roller 1 that is closely attached to the four walls of the continuous casting slab keeps rotating synchronously with the surface of the solidification shell 4 of the continuous casting slab, and at the same time, driven by the vibration source 3, it is perpendicular to the thickness direction of the slab or parallel to the drawing High-frequency and small-amplitude vibration in the billet direction, and transmit this vibration to the solidified shell 4 with the liquid core 5 through contact. The dendrites 6 growing at the solidification front of the solidification shell will be broken and broken under the action of this vibration. The vibration amplit...

Abstract

The present invention belongs to the field of continuous metal blank casting technology, and is especially the method of raising continuous cast blank quality and the vibrating support roller apparatus. While the vibrating support roller closely contacting the casing of the continuously cast blank casing rotates synchronously with cast blank, it vibrates in the direction perpendicular to the cast blank thickness or in the direction parallel to the blank drawing under the drive of the vibration source, and the vibration is transferred to the solidifying shell of the liquid core via contact. The vibrating support roller apparatus consists of vibrating support roller, vibration transferring pipeline and vibration generating source. The present invention can improve the quality of the continuous cast blank obviously.

Description

technical field [0001] The invention belongs to the field of continuous casting of metals, in particular to a method for improving the quality of continuous casting slabs and a vibrating support roller device. Background technique [0002] In the existing continuous casting production technology of steel, the central quality of continuous casting slabs is reduced due to separation and crystallization, especially the central segregation, central shrinkage cavity, and central porosity caused by high alloy steel and high carbon steel continuous casting slabs. The problem is the core problem that affects the quality of the rear rolled material. In order to solve the above problems, many patents and technologies have been developed in this technology for a long time. These patents and technologies are mainly divided into two categories: one is electromagnetic stirring technology; the other is soft pressing or casting and rolling technology at the end of solidification. Chinese P...
