Abstract
PURPOSE:To improve the durability, responsiveness, and accuracy by installing a compression coil spring between a load cell attached to one of upper and lower chocks and the other chock under a compressed condition. CONSTITUTION:Spring specifications such as spring constant, set load, and closed height of a compression coil spring 12 installed between upper and lower chocks 4a, 4b under a compressed condition are properly set not to exceed an overload safety value of a load cell 11 considering a varying range of roll gap S and a safety factor. Therefore, a detector 10 is avoided from breakdown because a rigid load is not applied to a load button 11a. On the other hand, a load applied to the load cell 11 is elastic, so that a sufficient durability in a practical range is ensured. During usual rolling, cooling water and rolling oil scatter and dust floats around a rolling mill 1, so that deviation of the spring constant of the spring 12 is prevented by covering the spring 12 with a flexible cover 16.
