Abstract
A method for continuously casting grain oriented electrical steel is disclosed. This method utilizes a controlled rapid cooling step, such as one using a water spray, to control the grain orientation in the finished product. The product formed not only has the appropriate grain orientation but also has good physical properties, for example, minimized cracking. In this process, after a continuously cast electrical steel strip is formed, the strip undergoes an initial secondary cooling to from about 1150 to about 1250° C., and finally undergoes a rapid secondary cooling (for example, by water spray) at a rate of from about 65° C./second to about 150° C./second to a temperature of no greater than about 950° C.
