Abstract

The invention relates to the field of metal solidification and continuous casting, in particular to an integrated-shaft and three-roller corner rolling device for continuous casting billet corner rolling. The device comprises a middle positioning roller (1), an upper chamfer roller (2-1), a lower chamfer roller (2-2), a roller shaft and a roller supporting frame (4); the roller shaft comprises a middle roller shaft section (3) and chamfer roller shaft sections (6) at the two ends; the chamfer roller shaft sections (6) and the middle roller shaft section (3) are arranged in an alpha angle manner; the middle positioning roller (1) is mounted on the middle roller shaft section (3); the upper chamfer roller (2-1) and the lower chamfer roller (2-2) are respectively mounted on the chamfer roller shaft sections (6); the chamfer roller shaft sections (6) are connected with the roller supporting frame (4); the alpha angle is 0-45 degrees; a roller surface slant angle beta of each chamfer roller is 30-70 degrees; and the alpha angle is less than or equal to the beta angle. The device effectively avoids the defects of shear cracks arising from shear rolling, an optimized casting billet corner chamfer shape can be obtained, and split or surface upwarping of the edge of a plate is eliminated.

Description

technical field

[0001] The invention relates to the fields of metal solidification and continuous casting, in particular to an integrated shaft three-roller corner rolling device for corner rolling of continuous casting slabs. Background technique

[0002] In the production technology of plate and strip in the modern world, the defects of straight edge cracking or warping are common. Defects are also further away from the edges of the sheet and further towards the center. Iron and steel enterprises have to adopt the method of increasing the amount of trimming and reducing the yield to remove the above-mentioned defects and meet the quality requirements. This results in a substantial increase in production costs for the enterprise.

[0003] For this reason, in addition to optimizing the quality of molten steel, secondary cooling technology, and reasonable rolling, metallurgists have adopted a major technical measure to adopt crystallizer technology with chamfering. In the ...
