The paper analyzes the construction,performance and working principle of SC pneumatic booster pump,and introduces its application in the hydraulic system of aluminum strip casting-rolling mill.

This article analyzes the main cause of producing of coarse grain on the cast-rolling strip according to the effect factors on grain size,put forwards the strategy of controlling and refining grain on cast-rolling strip.

The central crown of casting & rolling aluminium blank is an important parameter which has significant effect on the plate shape control in cold rolling course thereafter.
