Abstract: A refractory formulation containing an anhydrous solvent, an oleophilic rheology modifier and a refractory aggregate exhibits non-thermoplastic behavior, and remains plastic and formable at temperatures in the range of 10 degrees Celsius to 180 degrees Celsius. The oleophilic rheology modifier may effectively bind with the solvent to create a gel-like structure with organic solvents with moderate to high polarity. A phyllosilicate clay that has been treated with a quaternary fatty acid amine may be used as the oleophilic rheology modifier.

Abstract: A roll for use in glass manufacture, such as in the production of non-dusting TFT glass, includes a hollow silica cylinder. A rod extends through the interior of the silica cylinder. A cooling volume is contained within the cylinder and extends around the rod. End caps are mechanically fixed to the roll. Pulling flats are fixed in place by inner and outer end plates. A compression fitting secures at least the outer end plate to the roll. The rod may serve to reinforce the roll and may be secured to the shaft by a plurality of supports. The supports accommodate differences in thermal expansion.

Abstract: A device for blowing gas into a metallurgical vessel contains at least one gas flow channel fluidly connecting a gas inlet located at one end to a gas outlet located at the opposite end. The channel is in the shape of a slit. The gas channel contains a series of continuous concave bridges connecting the opposing surfaces defining the channel, with their concave side oriented towards the gas outlet. The concave bridges are disposed in a staggered arrangement, such that any shortest line running from the gas outlet to the gas inlet of the channel necessarily intercepts the concave side of at least one bridge. The device is resistant to clogging by infiltrated molten metal or slag.

Abstract: A nozzle for casting steel comprises an inlet portion, an elongated portion extending along a longitudinal axis from the inlet portion, an outlet portion comprising a front port, and a pouring bore. A planar cut of the nozzle outlet portion along a plane normal to the longitudinal axis comprises the outline of the outer peripheral wall of the outlet portion of the nozzle defined by the wall perimeter and the wall centroid of the area defined by said wall perimeter, and a first transverse axis passing by the bore centroid and extending along a direction parallel to the orthogonal projection of the front port direction onto the plane of the cut. The nozzle comprises no front port extending along a direction opposite to the direction of the first front port with respect to the longitudinal axis and belonging to the plane defined by the longitudinal axis and the front port direction. The distance from the wall centroid to the outer peripheral wall measured along the first transverse axis on the side of the front port is greater than the same distance measured on the side opposite the front port.

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.
