Title: Method for improving traveling of steel sheet after rolling
Inventor: NAMIDOKO NAONORI
IPC: B21B37/26
Filed: 1987-06-17
Abstract: PURPOSE:To make inertia of only the top part of a steel stock large and to improve traveling of the stock on a runout table by widening a roll gap at rear stands of a tandem rolling mill and bringing the gap after passing of the top part to a set value. CONSTITUTION:A roll gap at rear stands F6, F7 in stands F1-F7 of a tandem rolling mill 1 is initially set to a large value to roll a steel sheet 2. After the top part of the sheet 2 passes through the stands F6, F7, the gap is set to a prescribed set value and the rolling is continued. The sheet 2 is hardly affected by influences of air or contacting bodies, so that traveling of the sheet 2 on a runout table 3 is comparatively stable because the top part is thick and has a large material inertia.

Abstract: PURPOSE:To enable execution of secure simulation of various printing actions and prevent deterioration of printing quality by providing a resolution setting means for setting a resolution in accordance with printing information to be entered, a modulated frequency changing means for complying with the resolution, a focused state changing means and a scanned state changing means. CONSTITUTION:When a resolution complying with printing information which is entered into a resolution setting means C1 is set, the modulated frequency of a laser oscillator is changed by a modulated frequency changing means C2 in accordance with the set frequency and also an optical position of an optical system is changed by a focused state changing means C3. Then the scanned value of a scanning means is changed by a scanned state changing means. That is, both the beam diameter of a laser beam on a recording medium and a scanned state are controlled and printing information is recorded based on a beam diameter and a scanned state which meet its resolution. Consequently, it is possible to simulate a variety of printing actions, and also make effective use of the conventional printing information resources. Further, deterioration of printing quality and reduction of printing speed do not occur by secure execution of the simulation of printing actions.
