Abstract: In a device for fastening a perforated block to a metal melt container, the perforated block can be fastened by at least one clamping wedge which can be inserted transversely with respect to its through opening and which has a clamping jaw coupled thereto, wherein this clamping jaw acts on a clamping surface formed on the circumferential surface of the perforated block. The respective clamping wedge is guided in a carrier plate so as to be displaceable in its longitudinal extent or extension and transversely with respect thereto, while the clamping jaw coupled thereto can be moved in this transverse direction. Consequently, the perforated block can be fastened with precise positioning in the carrier plate in a simple manner.

Abstract: Pressing device for a casting pipe at the spout of a metallurgical container, wherein the pressing device is provided with spring-loaded pressing elements that can be pressed against guide surfaces of a casting pipe. The casting pipe includes a tubular part and an upper plate. The guide surfaces are arranged on the underside of the plate on both sides of the tubular part and are directed downward at an angle. They form a plate cross-section that is tapered downward. The pressing elements are each provided with a head that is convexly curved in the adjustment direction of the casting pipe and can be pressed against a guide surface of the casting pipe, which is curved in the longitudinal direction of the pressing element or in the adjustment direction. Compressive forces exerted by the pressing pins are optimally transmitted, more toward the casting pipe opening and therefore acting more evenly.

Abstract: A container for molten metal has at least one opening in which a refractory nozzle brick is mounted. A refractory purge plug or a refractory sleeve defining an outlet opening is inserted in the nozzle brick opening. A defined gap is formed between the nozzle brick opening and the purge plug or the sleeve and is filled with a refractory mass, this mass consisting of a material which can be easily bored or milled out of the mass for the purpose of replacing the purge plug or the sleeve. In this manner, laborious cleaning steps can be avoided and the nozzle brick no longer risks being damaged.

Abstract: The pouring spout changer according to the invention is characterized in that it is provided with a dummy plate (14) for closing the casting channel of the casting device in an emergency.

The changing device can also be used as a casting nozzle changer, preferably with a nozzle gripper for removing the worn casting nozzles.

Abstract: A copper anode furnace includes a furnace drum which can be pivoted about a horizontal axis and in which copper melt is refined into anode copper by fire refining. The furnace drum is provided with a spout for pouring out the refined copper. A sliding closure is arranged on the spout of the furnace drum. The sliding closure includes at least one stationary, fireproof closing plate and a fireproof sliding plate which can be displaced relative to the closing plate. Through the displacement of the sliding plate, the outflow out the furnace drum can be regulated or closed and therefore the outflow amount of the copper can be controlled. A drawing of slag into the casting, which reduces the anode quality, can be prevented using the sliding closure.

Abstract: A closing plate for a sliding closure on the spout of a receptacle for molten metal, especially of a converter, includes an elongate refractory plate and a sheet metal jacket surrounding the same.
