2013年9月1日 The calculation of force for a roll system has significant effects on cold rolled thin strip gauge adjustment of a 20-high Sendzimir mill. According to the rolling parameters and rolling plans of a ZR-22BS-42 Sendzimir mill in a silicon steel factory, the contact force and the resultant force of each roll in the roll system were calculated both in the static state and in the rolling

2017年8月29日 system, the result shows that the deformation has little effect on the stability of the roll system. Zhang et al. [7] built the three-dimensional elastic finite element model of the roll system of a Sendzimir mill in the roll contact zone by ANSYS, and calculated the complex deformation of the roll system.

2018年9月30日 Edge-drop control is important for silicon strip cold rolling, as the silicon strip is mainly used as a laminated core. Moreover, cold rolling is the key process for the thin strip edge-drop control, and a Sendzimir mill is one of the most popular cold rolling mills for silicon strips. Thus, the mastery of edge-drop control behavior for silicon strip cold rolling with a Sendzimir

4 天之前 The Work Roll in our Sendzimir Cluster mill is non-chock-supported, and it can easily be pulled out by hand or by a roll change cart for larger mills. This feature allows for a quick change of the Work Rolls, ensuring the surface quality of the strip reflects the refined polish of a new set of Work Rolls.

2014年5月1日 Twenty-high Sendzimir rolling mills (ZRMs) typically use small diameter work rolls to provide massive pass reduction. Because of the small diameter of the work rolls, a rolled steel strip has a complex shape mixed with quarter, edge, and center waves. When the strip shape is controlled automatically, actuator saturation occurs in the shape actuator such as AS-U rack.

2024年6月17日 The roll separating force on the 1-2-3-4 mill is distributed from the work rolls to the intermediate rolls and then to the backup shafts in such a fashion that the outer shaft takes a heavier force component, i.e., absorbs more load than the center shafts. The driven rolls in the mill are the outer second intermediate rolls.
