Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential
2020-4-9parameters. A large-deformation constitutive model applicable to the calculation of roll force and torque in heavy-reduction rolling was presented by Byon, Kim, and Lee 2004. 3-D FE analysis coupled with the proposed constitutive models has been carried out to calculate work-piece deformation and the rolling force in their investigation. An

Rolling demands difficult theoretical calculations for substantiation of the deformation modes for the purpose of the reduction of the number of passes and a reliable calculation of energy-power rolling mill parameters, etc. A wide range of rolling speeds in practice demand carrying out research at the corresponding deformation speeds
2018-6-4An improved calculation method for rolling pressure and load torque of electrical drive engine is suggested further. This method considers peculiar strain of product in high deformation ones and its accelerated motion in reverse mode. Improved analytical dependences for rolling pressure and load torque of electrical drive are reviewed
Calculation of roll force is important because calculation of torque and power in a rolling mill is based on calculation of roll force. Accurate prediction of roll force for grooved rolling is considerably more difficult than predicting the geometry of the rolling stock. There are essentially three problems, present during the rolling
Took the heavy cylinder rolling mill as subject investigated, which is used to produce the nuclear power cylinder, the large hydrogenation reactor cylinder and the coal liquefaction reactor cylinder.
