Embodiment Construction
[0029] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail in conjunction with specific embodiments.
[0030] The invention provides a method for calculating the temperature field of bloom rolling in consideration of uneven deformation heat.
[0031] The method includes steps as follows:
[0032] S1: Using the three-dimensional structural finite element method to establish a single-pass rolling calculation model for blooms:
[0033] S11: Establishing a three-dimensional geometric model of the single-pass rolling of the bloom according to the geometric dimensions of the rolled piece and the roll;
[0034] S12: Divide the geometric model established in S11 into units, first select the unit type, among which, select the 8-node hexahedron unit for the rolled piece, and select the quadrilateral shell unit for the roll, and then determine the grid division for each edge of t...
