Abstract From the Canadian patent

There are provided a continuous casting and rolling process for continuously producing a deformed fine grain solid metal composition suitable for semisolid forming. The process is characterized by high throughput due to its , continuity, and by precise control of the process parameter such as , solidification rate, rolling temperature and speed and total deformation. The solidification rate is preferred to be in a range of 10 to 150 ~C/s and the , total deformation is controlled to be larger than a Mises effective strain of 2.3 to obtain a deformed fine grain structure with enough distortion energy. A method combining the continuous casting and rolling process of preparing semisolid raw …
