Abstract: Proceeding from the dynamic state character of straightening deformation for CCB, the MECRS method is suggested in this paper, It moans, on the basis of analyzing the deformaition pattern of MECRS, the design formulas for MECRS are obtained and has been examined by existing information too. Based on the studies in reference [1], the relationship between MECRS and continuous straightening is discussed in this paper as well According to the computation samples, the strain rates and the needed roller forces of straightening will be greatly reduced on those multi-point straightening systems which are designed by the MECRS principle.

Key words: Continuous casting, Curvature, Straightening
