Abstract: A blast furnace head (11) including a material loading device comprising rotary chute (14) driven in rotation about a first, vertical axis of rotation (16), and a loading chute (15) at the outlet of same, driven in rotation about a second, vertical axis of rotation (17) laterally offset relative to the first axis of rotation (16). The gears (20, 21) assigned to both of the chutes (14, 15) are arranged within a sealing chamber (22). Within this sealing chamber (22), a means (28) is arranged for supplying integrated measuring devices (29 or 30), lubrication points or similar maintenance recipients, with these supply means (28) being drivable by one of the gears (20, 21) assigned to the two chutes, in particular by the gear (20) assigned to the rotary chute (14).

Abstract: An apparatus for controlled adjustment of a stopper of a distributor channel or metallurgical vessel in a continuous casting plant (for billets or ingots), the stopper being connected to a crosstie or stopper rod disposed above the distributor channel or metallurgical vessel, and the crosstie or stopper rod itself being connected to a support bar which is movable up and down in a vertical guide means. The vertical guide means of the support bar is a roller guide means comprising support rollers or support balls which are clamped without clearance between the support bar and an outer housing.

Abstract: A method and apparatus of controlling the pouring spout of a tundish for molten metals, including a slide valve composed of a valve member mounted for movement between a head plate disposed on the underside of the tundish and a discharge member. For preventing in a particularly effective way any freezing of the molten metal and for avoiding any static shadow corners the valve member and/or the head plate or both in the closed and/or open or part-open position thereof are moved in such a way that a two-dimensional relative movement perpendicular to the longitudinal axis of the pouring spout is generated between the valve member and the head plate.
