Embodiment 1

[0070] The parameters of the bending section and the straightening section of a slab continuous casting machine in a steel plant are the slab thickness D = 250mm, the slab width B = 2300mm, and the basic arc radius R 0 =10000mm, the length of the bending zone L b =1400mm, the length of straightening zone L s = 3150mm.

[0071] Then the continuous casting machine bending zone coefficient K b = 1.00747, bending zone angle α b =4.03399°, the total arc length S of the bending zone b =1400.7mm; Straightening zone coefficient K s =1.04056, straightening zone angle α s =9.30735°, total arc length S in straightening zone s = 3158.43 mm.

[0072] The coordinates of the starting point of the bending zone are (-10008.14, 696.52), the coordinates of the end point of the bending zone are (-9975.22, -703.48), the coordinates of the starting point of the straightening zone are (1532.7, -10040.43), and the coordinates of the end point of the straightening zone are (-1617.30, -9868.35 ...

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...
