A rolling mill device and method for roll profile design

Abstract

The invention relates to a rolling mill device and method for roll shape design. The device includes an upper work roll, a lower work roll, an upper support roll, a lower support roll, a roll shape comprehensive control system, an off-line work roll, and an off-line support roll. , shape meter and thickness gauge; the upper work roll, lower work roll, upper back-up roll, lower back-up roll, off-line back-up roll and off-line work roll are all electronic temperature-controlled rolls, and are all connected to the roll shape comprehensive control system ; Both the off-line work roll and the off-line back-up roll have a roll shape detection function; The instruments are all connected with the comprehensive control system of the roll shape. The present invention takes the plate shape as the roll shape design index, which is the most direct index to measure the plate shape control ability, and the method is more targeted, and the present invention can be mounted on four-roll mills, six-roll mills and other rolling mills of various specifications. Among them, the technical compatibility is strong, the roll shape design is more flexible, and the result is more intuitive.

Description

technical field [0001] The invention relates to the technical field of plate and strip rolling, in particular to a rolling mill device and method for roll profile design. Background technique [0002] The shape is the main evaluation index of the quality of the strip product. In order to obtain a good shape, the strip rolling mill often needs to have a certain ability to control the shape, so that the strip with a shape problem can be rolled into a good shape. Products; the core of shape control lies in the roll gap control, changing the shape of the rolls forming the roll gap through a variety of control means, and then realizing the control of the shape; as the main executive component of the strip mill, the exit shape state play a decisive role. At present, there are various forms of roll profiles, such as CVC roll profiles, ESS roll profiles, etc. Each form can match the machine characteristics and control characteristics to achieve different degrees of flatness control...

Problems solved by technology

[0003] However, the existing design methods are based on the roll shape design based on the parameters of the rolling mill and the control ability as the goal. The new roll shape after design needs to be processed and tested. After multi-specification testing, it can become a finished roll shape and put into production. This process Mainly relying on the designer’s design experience, it takes a lot of time to calculate the roll shape, and a lot of work is done in the selection of polynomial settings, which undoubtedly increases the cost of roll shape design. It is difficult to design the finished roll shape after repeated adjustments in processing testing and production practice. Therefore, it is urgent to develop a technical solution that can flexibly and simply design the roll shape
