(57) The purpose of the summary of the present invention, an apparatus and position control method of the edge dam with improved twin-roller type sheet casting process that minimizes the wear of the edge dam by minimizing the force applied to the edge dam during casting The present invention is to provide. The object of the unsatisfactory of the present invention, an apparatus and position control method of the edge dam to prevent leakage of so as not to be pushed rearwardly by a force less edge dam to maintain the quality of the sheet to be good The present invention is to provide. For the embodiment of the present invention, to improve the quality of the sheet, the twin roller type sheet casting process for controlling the position of the edge dam, there is provided a method for controlling the position of the edge dam. Step to calculate the results calculated with the position of the freezing point for force of the roller; casting during work, and step of measuring a load cell force of the roller actual contains the following stages in the method of the ; you match the position of the freezing point of the roller force could be measured, the height of the edge dam; and to determine the height of the edge dam and the current position of the freezing point for force was measured of the roller is whether there is a match , or stage an equivalent position to move the edge dam. In the form of unsatisfactory of the present invention, in order to achieve the same purpose as above, a twin-roller type sheet casting process for casting a thin plate and includes an edge dam on both sides of the roller and twin casting rollers, the present invention is the position of the edge dam An apparatus for improving the quality of the sheet by controlling, edge dam and also pressed by a constant force to the roller side end portions in the hydraulic cylinder, which is connected therewith and edge dam disposed on both sides of the twin rollers, the edge dam edge dam horizontal control device with a horizontal position measurement sensor that measures the horizontal displacement; includes a hydraulic cylinder located on the lower surface of the edge dam horizontal control device, which controls the vertical movement of the edge dam in the hydraulic cylinder, the vertical displacement of the edge dam load cell force to measure the force of the roller applied to the sheet by the load cell the roller to measure the force of the edge dam by the edge dam horizontal control device; edge dam vertical control apparatus having a vertical position measurement sensors that measure and, above load cell twin-roller, characterized in that it comprises; controller that utilizes the edge dam vertical control unit height of the edge dam to match with the position of freezing point which is calculated basis on force of the roller, to position moving edge dam It is an edge dam position control device of the sheet casting process.
