摘要： PURPOSE:To adjust continuously in a short time the width of a slab in large quantity by compressing the slab continuously while vibrating specifically a press tool having a taper part and a straight one, in a press-type width adjusting method of slab before thickness-reducing rolling. CONSTITUTION:Both width ends of a slab 1 is compressed while vibrating it in the width direction by press tools 8 having each a taper part and a straight one in the width direction, and the slab width is adjusted by continuously pressing the slab 1 against the tools 8 in the direction of material flow. At that time, a pressing load acts in a state of being distributed to the length (l) during the stationary width adjustment of the slab 1, and the buckling in the width direction of the slab 1 is hard to occur because of the presence of materials at its front and rear sides, and the vibrational amplitude can be made larger. But when the front tip of slab 1 is situated at the taper part of the tool 8, the pressing load is concentrated at the front tip of the slab 1, which is buckled by a small load because its front end is free from said restriction. Accordingly the amplitude (a') is made smaller than the (a) till the front tip arrives at the straight part 8 (l) of the tool 8.
摘要翻译：目的：通过在板坯连续振动的同时特别振动具有锥形部分和直线的压制工具，在短时间内连续地调节板坯的宽度，同时振动板坯的压制宽度调节方法，减少滚动。构成：通过在宽度方向上具有锥形部分和直线的压力工具8在宽度方向上振动板坯1的两个宽度端部，并且通过连续地将板坯1压靠在板坯1上来调节板坯宽度工具8在材料流动的方向。此时，在板坯1的固定宽度调整期间，按压负载作用在分配给长度（l）的状态，并且由于存在着板坯1的存在而难以发生板坯1的宽度方向的弯曲其前侧和后侧的材料，并且可以使振动幅度更大。但是，当板坯1的前端位于工具8的锥形部分时，由于其前端没有所述限制，所以压制载荷集中在板坯1的前端部，该前端部被小负载弯曲。因此，使幅度（a'）小于（a）直到前端到达工具8的直线部分8（l）。

摘要： PROBLEM TO BE SOLVED: To provide the control method of rolling equipment with which the effect of the thickness control in a rolling mill is maximized in the stable range of automatic gage control. SOLUTION: This equipment is the rolling mill which is composed of the main body of the rolling mill and reels on the inlet and outlet sides and rolling equipment to which an inlet-side tension control for controlling the tension between the inlet-side reel and the main body of the rolling mill and automatic gage control for controlling the thickness on the outlet side of the rolling mill are applied. The control gain of the automatic gage control is set (201), the control gain of an inlet-side tension control system is calculated (202), consistency is checked by comparing both the above control gains (203) and the control gain of the inlet-side tension control system is adjusted so that the effect of the thickness control is maximized in the stable range of the automatic gage control (206). The stability of the inlet-side tension control is checked (204) and, when the stability is not attained, the control gain of the automatic gage control is changed (207).

摘要： PROBLEM TO BE SOLVED: To reduce unstable phenomena such as hunting of a tension system by controlling in such a way that the control response differs between the control system to control the tension given to a strip to be delivered from an unwinder and introduced into a rolling mill and the control system to control the tension given to the strip to be wound by the winder after rolled with the rolling mill. SOLUTION: A winding/unwinding command unit 11 issues a speed/tension command 15 to a winding/unwinding machine 3 on the right side so as to keep the winding tension constant, and issues a speed/tension command 14 to a winding/unwinding machine 2 on the left side so as to keep the tension constant. The winding/unwinding command unit 11 indicates different tension responses to a motor 6 and a motor 7 respectively. It is preferable that the control response of the tension control given to the strip 4 to be introduced into the rolling mill 1 is faster than the response of the tension control given to the strip 4 to be wound after rolled with the rolling mill 1.
