COPPER TUBE OF EXPONENTIAL FUNCTION CRYSTALLIZER

摘要

A copper tube of an exponential function crystallizer. The copper tube of the exponential function crystallizer is a rectangular tube. One end of the copper tube of the exponential function crystallizer is a copper tube upper opening (1), and the other end thereof is a copper tube lower opening (2); and a cavity of the copper tube of the exponential function crystallizer is gradually reduced from the copper tube upper opening (1) to the copper tube lower opening (2) and changes according to an exponential function. A exponential function curve is used to describe the face taper and diagonal line taper of the copper tube, which conforms more to a solidification shrinkage rule of a casting blank in the longitudinal direction, and ensures uniform distribution of temperature and stress of the casting blank in the peripheral direction, thereby ensuring stable high-speed continuous casting.
