technical economy
6.In this article,the author discusses the application of ball rolling technique to the process of cylinder,narrates the process and structural speciality of rolling apporatus by analysing the rule and parameters of fulfiling rolling technique. Its striking technical-economy effect is proved by operation of mathematical formula and the preparation information in process is pointed out.
