Abstract The invention relates to a slag-scraping apparatus which is intended to operate automatically and in connection with a casting apparatus operating by the continuous-casting method. The apparatus includes a stationary scraper blade (7, 8) and a movable blade (4, 5, 7) which moves by transmission of an arm (5) driven by drive rolls (6). The above- mentioned blades are articulated by means of an intermediate arm (10) to an arm (13) attached to the frame, and the intermediate arm (10) for its part is articulated by mediation of an arm (14), a turning arm (18) and a drive cylinder (15) to the turning arm (24) of the set formed by the same, the arm (24) being driven by a turning device (22). The blades can be lowered into the mold (1),and the movable blade (4, 5, 7) can be brought all the way to the stationary blade (7, 8) in order to collect the slag. Thereafter the blades can be raised by joint operation of the cylinder (15) and the turning arm (24) up and to the right, entirely away from above the mold. Thereafter the movable blade (4, 5, 7) can be moved away from the stationary blade (7, 8), at which time the slag between the blades falls into a container. The blades are always kept in a similar position, in spite of the movements of the arms (10, 13, 14, 24), by means of a parallelogram lever set. Figure 1 has been selected for the abstract.
