摘要： An inner nozzle is capable of being mounted onto a tube exchange device for holding and replacing an exchangeable pouring nozzle for casting molten metal out of a vessel. The tube exchange device is constructed of a frame with a casting opening. The frame is configured to be fixed to the lower side of a metal casting vessel and has a first, upper portion and a second, lower portion, joining at a middle section plane defining the plane where an inner nozzle and an exchangeable pouring nozzle form a sliding contact. The upper side portion of the frame receives and clamps in place a bearing surface of an inner nozzle at its pouring position. The lower portion comprises elements for loading and moving along a first direction (X) into casting position an exchangeable pouring nozzle. At least two clamping elements are arranged transverse to the first direction (X).

摘要： An inner nozzle for casting molten metal from a metallurgical vessel incorporates a substantially tubular portion with an axial through bore, and an inner nozzle plate comprising a bottom flat contact surface and a second surface opposite the bottom contact surface and joining the wall of the tubular portion to the side edges of the plate. The inner nozzle incorporates a metallic casing cladding at least a portion of some or all of the side edges and second surface but not the sliding plane of the inner nozzle plate. The cladding is provided with a metallic bearing surface, facing towards and recessed with respect to the contact surface and extending from the cladded portion of the side edges beyond the perimeter of the contact surface. The bearing surface is defined by the ledges of at least two separate bearing elements distributed around the perimeter of the plate.

摘要： A refractory nozzle comprises a substantially tubular portion with an axial through bore and a plate comprising a first, contact surface normal to the axial through bore and comprising the outlet opening, and a second surface opposite to the first contact surface joining the wall of the tubular portion to the side edges defining the perimeter and thickness of the plate. All but the first contact surface of the inner nozzle plate are at least partially clad with a metal casing having side edges. The inner nozzle plate metal casing comprises three separate bearing elements jutting out of the side edges. Each bearing element comprises a bearing ledge facing in the direction of the contact surface and distributed around the perimeter of the plate. The centroids of the orthogonal projections onto a plane parallel to the contact surface of the bearing ledges form the vertices of a triangle.

摘要： A frame, for a device for holding and replacing plates for transferring molten metal contained in a metallurgical vessel having a casting channel, defines a housing for receiving and holding a plate, when the device is assembled, in the operating position in the vicinity of the casting channel of the metallurgical vessel. The frame is arranged to enable the introduction of the plate into the housing, and the extraction of the plate from the housing, by translation along a plate insertion direction. The housing is formed so as to have an overall planar symmetry in relation to a central longitudinal plane parallel with the plate insertion direction. The frame comprises slots for receiving thrusters intended, when the device is assembled, to apply a force, in the direction of the metallurgical vessel, on a plate inserted in the housing.

摘要： A tube for pouring liquid metal has a pouring channel with a pouring axis. The tube has a downstream part with a pouring channel with an outlet diameter, and a flared upstream part with a length known as the threshold distance. The threshold distance is greater than four times the outlet diameter. The upstream part is flared and configured so that its upper end has a convex overall shape in the axial direction. The upstream part is included within a first volume corresponding to the complementary part of an axisymmetric frustoconical volume having as its axis the pouring axis. The generatrix of the volume forms an angle greater than 5 degrees with the pouring axis. The upstream part is included within a second volume, delimited by a surface of revolution generated by an isosceles trapezium revolving about the pouring axis.
