2800 and 3500 rolling mill stand roll means is provided in the inlet and outlet side of the mill, one at each side groups of three, a total of two groups of six each rolling mill. 350. rack mill roller device. Six rollers are active, driven by six motors; 2800 chassis roll mill in each group only the middle one active and two passive rest, only two motor driven. Rack roll is solid roller bearing wedge block and hydraulic tensile bolts rigidly attached to the rack, using large-size roller bearings are self-aligning spherical bearings.
To be able to easily replace the rack roller shaft using a movable shaft axially telescopic shaft. In the long tooth gear coupling as secondary shrink connection. In a small motor rack and pinion drive shaft telescoping manner, the drum-shaped roller end of the inner and outer sets of teeth isolated teeth, to replace the roller. Rack roller long-term work in 1200 a 90 ℃ environment. Water, steam and iron oxide skin more. To withstand greater impact. And to consider the impact of unforeseen withstand steel elbow section, the working environment is bad.
(1) This device functions to meet the same conditions, lower life cycle costs chassis roll, namely manufacturing costs and use so as not to;
A (2) Shaogang 2500 mill stand roll means is welcomed by the users of the more advanced and reasonable structure type, so the structure of the rack roller means to do too much without improvements, and the need to improve the chassis roll materials and processing methods apparatus. Rational selection of materials and processing methods to reduce manufacturing costs through economies rack roller means;
(3) 2800 mill Wuhan Iron and Steel and Jinan Iron and Steel and Shaoguan Iron and Steel 2500 3500 mill mill rolls means for comparing the rack, structure basically the same, but the size is inconsistent. How to correctly select the size of the parts, in order to ensure product functionality while minimizing weight. 280. Therefore, Wuhan Iron and Steel and Jinan Iron and Steel to carry out 3500 mill roller device VE analysis based on the rack, that is how a reasonable choice of part size, weight, material and processing methods to reduce manufacturing costs.
