Abstract
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 ...
