ժҪ 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 state through C++ programs. It was found that the contact force between the second intermediate driven roll and the back-up rolls B and C was much lower than that between the other rolls in static state. The results also demonstrated that the resultant force are 59��5%-62%, 37��7%-40��3%, 87��1%-88��7% and 53��9%-56��7% of the rolling force at the second intermediate driven roll, the second intermediate idler roll, the back-up rolls B and C and the back-up rolls A and D, respectively. It was also revealed that the minimum contact force generated between the first intermediate roll and the second intermediate idler roll is 206��7 kN on the first rolling pass, and that on the second rolling pass, the minimum contact force generated between the second intermediate driven roll and the back-up roll C is 470��7 kN.
