Problems solved by technology
However, none of the above-mentioned methods for establishing the rolling force model of extra-thick plates takes into account the temperature rise effect of the rolling process. Therefore, the precision of the rolling force of extra-thick plates calculated by the above-mentioned method is limited and cannot provide effective information for rolling production. guide
[0004] Therefore, in order to solve the problem that the temperature rise effect is not considered in the process of establishing the rolling force model of extra-thick plate in the prior art, it is necessary to provide a method that can consider the temperature rise effect in the calculation process to improve the accuracy of rolling force prediction and to The method of establishing the rolling force model of extra-heavy plate that provides effective guidance for rolling production

The embodiment of the invention discloses a method for establishing a rolling force model of an extra-thick sheet. The method for establishing the rolling force model of the extra-thick sheet comprises the steps of constructing a velocity field, calculating rolling power and minimizing the rolling power, calculating temperature rise, introducing temperature rise into a deformation resistance model, and nesting temperature rise into the rolling force model to obtain rolling force related parameters. According to the embodiment of the method, temperature rise is introduced into the deformation resistance model in the calculation process, so that the prediction precision of the rolling force is effectively improved, and rolling production can be effectively guided.
Description
technical field [0001] The invention relates to the technical field of metallurgy, in particular to a method for establishing a rolling force model of an extra-thick plate in consideration of the temperature rise effect in the modeling process. Background technique [0002] Calculation of rolling force is the basis for checking mill strength and process design and optimization. When rolling extra-thick plates, if the preset rolling force is too small, the metal deformation will not penetrate into the center of the slab, and the expected effect will not be achieved; while the preset rolling force is too large, it will increase the difficulty of the billet biting, It is difficult to achieve stable rolling. Therefore, when rolling extra-thick plates, it is more necessary to accurately calculate the rolling force to ensure the design and optimization of process parameters within the allowable range of the rolling mill. [0003] At present, Lai Hong and others have used Deform ...
