Method for controlling rolling mode of temper mill

The invention discloses a method for controlling a rolling mode of a pinch pass mill set so as to control 1# and 2# frames of the pinch pass mill. The method can realize the optimum control for specific elongation by choosing a proper rolling mode according to device parameters of a singe and double dual purpose pinch pass mill set and the technique parameters of belt materials, wherein the device parameters comprise a frame stiffness and ultimate tension and the technique parameters comprise the roughness of supplied material, the allowed scope for the roughness of the finished products, andthe allowed scope for the specific elongation. The method can fully satisfy the customers in product mechanical property, surface quality, and the like, enhance the adaptability of the mill set to the products, lower the investment cost, exert the potential of the mill set and promote the use ratio of the device. The method of the invention is simple, clear and is suitable for on-line application.
