Title:
【発明の名称】双ロール式連続鋳造法
Document Type and Number:
Japanese Patent JP3276151
Kind Code:
B2
Abstract:
A twin-roll type continuous casting device is provided which can produce sheets having good mechanical strength obtained through uniform crystal grain refinement and smooth and low surface roughness obtained by reducing variation in the quality of material and reduce equipment costs. A temperature of a cast piece C obtained by being solidified by means of a pair of water-cooled casting rolls (2a, 2b) is regulated to fall within a temperature range where an austenite structure exists in its own matrix, and after it has been so solidified, the cast piece is then rolled by means of an inline rolling mill (5) at a temperature ranging from 850 DEG C or higher to 1350 DEG C or lower and with a rolling reduction ranging from 5 % or higher to 50 % or lower in one pass, whereby the variation in total elongation of steel material is kept within 5 % in standard deviation.
