Abstract：

Ultra thin, ultra wide and high quality magnesium alloy sheets have a great market demand. However, magnesium alloy posseses poor plastic formability at room temperature, magnesium alloy sheets of horizontal continuous casting exist defects. Based on the AZ31 magnesium alloy continuous casting and rolling technology research, the result that the secondary cooling is a very effective method for controlling grain size is obtained,which improves the quality of magnesium alloy sheets. Prehat treatment before rolling and multiple rolling can make the grain dynamic recry stallized and refined, which are the prerequisite conditions for the production of high quality alloy thin sheet. By continuous casting and rolling, the ultrathin, ultra wide, high quality magnesium alloy thin sheet can be produced.
