The invention provides a rolling control device and a rolling control method, wherein the plate thickness between the pedestals can be calculated in a high-efficiency manner without additionally arranging any special hardware. The centring arrangement of a plurality of rollers is adopted, the thickness of the plate on the outlet side opposite to the roller of the last segment of the rolling sequence can be acquired, and based on the plate thickness of the outlet side, the plate thickness of the inlet side can be calculated according to the mass-flow conservation principle. The calculated result of the plate thickness of the inlet side opposite to the roller can be used for the repeated calculation of the plate thickness of the rolled material sent by the roller pair abutting against the front part, and therefore the plate thickness of the inlet side of the roller pair can be calculated, the error between the plate thickness of the inlet side of the roller pair arranged on the starting end and the plate thickness of the roller pair calculated by using other methods can be calculated. Based on the calculated errors, the above mentioned errors can be corrected. |
