Embodiment Construction

[0033] Next, the present invention will be described in detail with reference to the accompanying drawings.

[0034] figure 2 is a block diagram of a device for controlling the edge shape of a strip in a twin-roll continuous strip casting process (hereinafter referred to as "edge shape control device") according to an embodiment of the present invention, image 3 is a view showing the position of the cylinder attached to the side fender.

[0035]Such as figure 2 As shown, the edge shape control device includes: a side baffle driving device 100, which is attached to both sides of the casting roll, so as to control the pressure of the side baffle to the casting roller according to the wear rate and upward displacement rate of the side baffle. The pressure of the rolls and the upward displacement of the side baffles; cameras 200, which are arranged on both sides of the side baffles on the exit side of the casting roll 12 that discharges the strip 12, and the cameras are used ...

Abstract

Disclosed herein are an apparatus and method for controlling the edge shape of a strip in a twin-roll strip casting process, which improve the quality of the strip by using cameras to photograph the edge portions of the strip being cast by strip casting, analyzing the photographs, and then controlling edge dams according to the edge shape of the strip. The apparatus comprises: an edge dam driving unit which is attached to edge dams attached to both sides of casting rolls so as to control the pressing force of the edge dams against the casting rolls and the upward shift of the edge dams according to the wear and upward shift rate of the edge dams; cameras which are disposed at the strip outlet side of the casting rolls so as to photograph the edge portions of the strip; and a control unit which analyzes the edge shape of the strip from images photographed by the cameras and outputs a signal controlling the wear and upward shift of the edge dams.

Description

technical field [0001] The present invention relates to the control of the edge shape of the strip steel in the continuous casting process of strip steel, and more particularly, to the device and method for controlling the edge shape of the steel strip in the process of continuous twin-roll strip steel casting, said Apparatus and method to improve strip quality by taking pictures of edge portions of strip cast by continuous strip casting with a camera, analyzing the pictures, and then controlling side fences according to the edge shape of the strip (edge ​​dam). Background technique [0002] figure 1 is a view showing the structure of a strip continuous casting apparatus according to the prior art. Such as figure 1 As shown, an important process of continuous strip casting usually takes place in the molten pool between two rolls 1 and 2 rotating in opposite directions to each other. [0003] When the molten steel is supplied from the hopper 4 to the molten pool 9 through...
