Edge dam of twin roll type strip caster

An edge dam of a twin roll type strip caster is provided as a refractory material having a sealing member for sealing both end surfaces of a pair of casting rolls, and is pressed and raised according to wear of the sealing member. To uniformly maintain a contact area of the sealing member and the casting roll in a process in which the edge dam is moved while the edge dam is pressed and raised, both sides and a lower part of the sealing member are formed as an inclined surface inclined inwardly of the sealing member. An angle of inclination of the inclined surface is increased in a direction in which the sealing member is raised, and the angle of inclination [theta] of the inclined surface is obtained by a relationship between a moving distance l due to raising of the edge dam and a wear depth d. 本发明涉及种双辊式薄板铸造机的边缘挡板，所述边缘挡板具有密封对轧辊的两端面的密封部件，并由耐火材料构成，且随着所述密封部件的磨损实施加压及上升，所述密封部件的两侧和下部形成为向密封部件内侧倾斜的倾斜面，以在所述边缘挡板实施加压及上升移动的过程中，所述密封部件与所述轧辊保持定的接触面积，所述倾斜面的倾斜角度向所述密封部件上升的方向增加，所述倾斜面的倾斜角度(θ)根据基于边缘挡板的上升的移动距离(l)和磨损深度(d)的关系求出。
