Abstract: A low-water-content castable composition produces cast products with an increased modulus of rupture, an increased cold crushing strength, and decreased porosity. The composition employs closed fractions of constituent particles with specified populations and specified gaps in the particle size distribution to produce these properties. The composition is suitable for refractory applications.

Abstract: Abstract of DisclosureThe invention includes an end cap that can be securely mounted to the end of a ceramic spool. The end cap comprises a locking plate adapted to fit into a groove in the ceramic spool. A plurality of angularly offset holes in the locking plate align with similar holes in the end cap. Screws or pins are placed in the holes and welded in place to prevent backing out or loosening. In use, the locking plate is secured by the pins, the groove and the inside surface of the end cap, the combination of which inhibits misalignment. Thermal cycling does not loosen the end cap, cause eccentric rotation or crack the ceramic spool.

Abstract: A thin slab nozzle contains a central bore extending downstream along longitudinal axis X1 from an inlet orifice at an upstream end. The central bore comprises an upstream bore portion with a height Ha, in communication with a converging bore portion of height He, in communication with a thin bore portion of height Hf ending at the upstream end of a divider, and first and second front ports separated from one another by the divider and coupled to the central bore portion at least partially at the converging bore portion. X2 is a transverse axis, normal to X1, along which the nozzle becomes thinner in a downstream portion. In a section of the thin slab nozzle along a symmetry plane Π1 defined by X1 and by X2, the bore wall of the converging bore portion is curved at all points, and Hf/He≤1.

Abstract: A formulation containing polymer, resin and cement combined with aggregate can be used as a gunnable mix that is applied to a surface by being conveyed pneumatically in dry form to a nozzle, where water is added. Polymer in the gunnable mix enables it to adhere and bond to a surface, such as carbon brick, of a lining of a vessel used for the containment of molten metals. The formulation may be used, for example, to repair and protect blast furnace hearth linings.

Abstract: A refractory block configured to surround an outlet modifies, within a refractory vessel, the flow of molten metal passing through the outlet. The block takes the form of a base through which a main orifice passes, and a wall extending upwards around the periphery of the base. Structural features that may be included in the block include a circumferential lip around the exterior of the wall, an interior volume in which the radius decreases downwardly towards the main orifice in a plurality of steps, and flow openings in the wall that are configured to induce swirling in the flow pattern in the interior volume of the block.

Abstract: A pour tube for casting molten metal is adapted to reduce turbulence and mold disturbances, thereby producing a more stable, uniform outflow. The pour tube has a central longitudinal axis and includes a bore in communication with a port distributor having a greater radius with respect to the longitudinal axis than does the bore. Exit ports provide fluid communication between the port distributor and the exterior of the device. Each of a pair of larger exit ports has a larger cross-sectional area than does either of a pair of smaller exit ports.

Abstract: A tube exchange device for holding and replacing refractory nozzle comprises a frame with a casting opening. The frame is configured to be fixed to the lower side of a metal casting vessel. The frame is has an upper portion and a lower portion joining at a middle section plane in which an inner nozzle and an exchangeable pouring nozzle form a sliding contact. The lower portion of the frame contains a displacing element and a guiding element disposed for displacing and guiding the nozzle from a standby position to a casting position, and a pressing element pressing the nozzle at the casting position towards the upper portion of the frame. In a combination of the tube exchange device and a nozzle, the nozzle comprises bearing elements mating with the clamping elements of the tube exchange device.
