Embodiment Construction

[0061] Embodiments according to the present invention are described below with reference to the accompanying drawings:

[0062] First, the general structure of a six-stage rolling mill (UC mill) in an embodiment of the present invention will be described. Figure 4 It is a side view of the six-stage rolling mill of this embodiment. Figure 5 and Figure 6 for along Figure 4 Sectional view in the direction of arrows II and I in the middle.

[0063] Such as Figures 4 to 6 As shown, the six-stage rolling mill includes a pair of upper and lower work rolls 2 that are in direct contact with the workpiece 1 to roll the workpiece, a pair of upper and lower intermediate rolls 3 that support each work roll 2, and a pair of upper and lower intermediate rolls that support each intermediate roll 3. Reinforcing roller 4. A bearing bush 8 and a bearing bush 9 are mounted on each roll end of the work roll 2 and the intermediate roll 3 . Such as Figure 5 As shown, work roll bending d...

Abstract

The invention provides a rolling mill and rolling equipment. The rolling mill is provided with a pair of upper and lower work rolls for rolling the work pieces, a pair of upper and lower intermediate rolls for respectively supporting the work rolls, a pair of upper and lower reinforcement rolls for respectively supporting the intermediate rolls and roll bending devices for respectively imparting bending forces to the work rolls and the intermediate rolls. In the case the maximum usable width of a rolled stock is Wmax (mm), the diameter Dw of the work roll is defined as the range of 300+50× (Wmax-1200) / 300<=Dw<=375+50× (Wmax-1200) / 300, the diameter Di of the intermediate roll is defined as the range of Dw<=Di<=450+75× (Wmax-1200) / 300, and a work roll driving device for rotationally driving the work rolls is provided.

Description

[0001] This divisional application is based on the divisional application of the Chinese patent application with the application number 021218765, the application date being February 28, 2002, and the invention title being "rolling mill and rolling equipment". technical field [0002] The invention relates to a rolling mill, rolling equipment and a rolling method. Background technique [0003] JP57-202908A and JP62-275508A disclose a six-stage rolling mill (hereinafter referred to as "UC machine") in the field of rolling, especially in cold rolling equipment, wherein the above-mentioned UC machine includes a machine for applying bending to work rolls and intermediate rolls Forced roll bending means and at least one moving means for moving the intermediate roll in the axial direction of the rolls. Another rolling mill is disclosed in JP1-154807A. [0004] JP57-202908A describes that if the diameter of the intermediate roll is equal to or greater than 1.5 times the diameter o...
