Coordinate computing method for continuous bending roller rows and straightening section roller rows of slab casting machine

Abstract

The invention provides a coordinate computing method for continuous bending roller rows and straightening section roller rows of a slab casting machine, which comprises a bending section roller row coordinate computing method and a straightening section roller row coordinate computing method. The two methods firstly confirm and compute all parameters of continuous bending section roller rows and straightening section roller rows of the slab casing machine, then build a minimum optimization function according to the arc length and coordinate relation between a starting point and a tangent-point point range on the bending sections or the straightening sections, resolve according to a simplex method to obtain coordinates of all tangent points, and finally achieve coordinates of all roller rows according to coordinates of all tangent points. The coordinate computing method can quickly and accurately compute coordinates of inner arc roller rows and outer arc roller rows of the slab casting machine and provides scientific and accurate basis for engineering design and installation.

Description

technical field [0001] The invention relates to a design method for a roll row of a slab continuous casting machine in the iron and steel metallurgy industry. technical background [0002] The straight arc slab continuous casting machine adopts a new type of support guide roll curve with continuous bending and straightening, and applies the continuous bending and straightening technology to the bending section and straightening section, which can make the cast slab bend and straighten throughout the whole process. The deformation is uniform and continuous within the length of the section, and a smooth transition is realized during the deformation process, which effectively guarantees the quality of the slab. Because the straight arc continuous casting machine has lower equipment height and less construction cost than the arc continuous casting machine, it is widely used in modern slab continuous casting production. [0003] Since domestic iron and steel enterprises and meta...

Problems solved by technology

[0003] Since domestic iron and steel enterprises and metallurgical design institutes usually design and apply continuous casting machines in cooperation with VAI, SMS and other international enterprises, although continuous bending and straightening continuous casting machines are currently widely used, how to calculate the There are few reports on the specific method of roll coordinates. In order to realize the localization of straight arc continuous casting machines, it is necessary to summarize a complete set of calculation methods for roll coordinates of continuous casting machines based on engineering applications.
