The Latest Technology of the Heavy Plate leveler

摘要

Due to a recent surge of requirements for flatness and reduction of residual stress and also due to a demand for improvement of productivity,innovative heavy gauge plate levelers (hereinafter referred to as the plate leveler or the leveler) have been developed.1) Our company has supplied as well plate levelers of our own development from 1965,and as the most advanced plate leveler,we have brought a plate leveler having a deflection correcting function of the 4th generation,which is called as dynamic crowning control system,into actual use in 1998.2) After that,we have established this deflection compensating technique and peripheral technology associated with the core technology through designing and supplying of 12 sets as of the end of 2010.In this paper,this 4th generation plate leveler technology and the peripheral technology having been established in association with it will be mainly presented.
