| Abstract: | This paper discusses the necessity, possibility and economic benefits to improve the yield rate of wide and heavy plate ,analyzes the major influencing factors of yield rate of wide and heavy plate ,puts forward the proposal to maintain the rectangularity of wide and heavy plate plan view pattern by means of side edging, short stroke control and broadsiding compensation techniques on the basis of evolution law of wide and heavy plate plan view pattern, proves the effect of combined application of the above three roiling techniques on the improvement of wide and heavy plate rectangularity and yield rate from both theory and practice on the basis of finite element simulation and practical application. |
