Abstract


Pressure system in the pressure screw and nut mill power transmission line is the weak link, Base load is the key component parts.Which is easy to wear pressure nut, thread root fracture accidents occur frequently, Pressure in the rolling mill 4300 of a system thread Vice root breakage occur, Resulting in plant shutdowns, Affect the plant’s normal production order, To plant a huge economic losses。Analysis of the pressure system thread Vice occurred mainly due to root fracture when rolling the enormous impact of the load transient.The paper mill on the 4300 Vice-pressure system to transform the thread, and the use of finite element analysis software ANSYS, and the pressure plate rolling process simulation system thread Vice analysis. First, based on field data, using theoretical rolling force calculated rolling force, and then with the ANSYS finite element analysis software for the simulation of plate rolling process simulation derived from comparison of rolling force, rolling force as the largest selection Vice-pressure system suffered the maximum pressure screw. Finally, using the maximum force on the rolling mill pressure before and after transformation of the finite element simulation of the system, and verify the pressure in the rolling mill 4300 to improve the feasibility of the system thread Vice.
