HYDRAULIC SYSTEM FOR HYDRAULIC ROLLING-DOWN DEVICE OF ROLLING MILL

摘要

PURPOSE: To improve the response characteristics of hydraulic system by reducing the pressure drop of hydraulic pressure on the inlet of servo valve that is generated when rapidly opening the servo valve in the hydraulic system of hydraulic rolling-down device which is used for a rolling mill for the metallic sheet of steel sheet or the like. ;CONSTITUTION: In the hydraulic system for hydraulic rolling-down device of rolling mill, an accumulator 9 with a prescribed capacity is arranged within three meters of the inlet of the servo valve 4 with which rolling reduction is controlled.;COPYRIGHT: (C)1993,JPO&Japio
