摘要： The invention relates to steel processing in a ladle used for ferrous metallurgy. The inventive method for agitating steel in a ladle consists in blowing steel from the bottom with gas or a gas-powder mixture through blowing units. At least one blowing unit is shifted with respect to the vertical axis of the ladle toward the wall thereof. During the blowing, the ladle is rotated around the vertical axis thereof in such a way that the direction of rotation is periodically changed to the opposite direction. When the ladle is turned at an angle of 360°, the blowing is carried out through the blowing units disposed on the radius of the bottom of the ladle. When the ladle is turned at an angle equal to or greater than 180°, the blowing is carried out through the blowing units disposed on the diameter of the bottom of the ladle. When the ladle is turned at an angle equal to or less than 90°, the blowing is carried out through the blowing units disposed on the mutually perpendicular diameters of the bottom of the ladle. When the ladle is turned at an angle α equal to or greater than 360°, the blowing is carried out through the blowing units disposed in the sector of the ladle having the central angle α.

摘要： The invention concerns a method of coating a hydrophobic substrate (5,15,16) with a hydrophilic protective layer free of organic carbon (20A,20B,20C,20D) to protect the substrate (5,15,16) when used at high temperature. The method comprises: applying one or more layers of a slurry comprising hydrophilic colloidal particles and/or hydrophilic inorganic polymeric particles onto the hydrophobic substrate followed by drying to form a heat stable intermediate bonding layer on the hydrophobic substrate. One or more layers of a slurry forming the hydrophilic protective layer are applied onto the intermediate bonding layer followed by drying and/or heat treating to form the hydrophilic protective layer on the intermediate bonding layer. The slurry forming the intermediate bonding layer contains at least one carbon compound selected from hydrophobic carbon monomers and hydrophobic carbon polymers and comprising hydrophilic substituents in an amount sufficient to bond the hydrophilic colloidal/inorganic polymeric particles to the carbon compound(s).

摘要： A metal melting closed furnace (10) which includes a main chamber (26), a circulation well (28) connected to the main chamber (26) by a communications passageway and a vortex well (84) having an exit outlet for molten metal into the main chamber (26). A cover (138) is emplaced over the vortex well (84). An inert gas bubble activated molten metal pump (48) is provided in which there is an entry port in the circulation well (28) and exit port (64) tangentially arranged with respect to the periphery of the cavity. This exit port (64) will typically be at or near the top of the vortex well (84). In order to reduce oxidation, inert gas bubbles are captured from this molten metal pump (48) and are transported to an inert gas atmosphere or blanket above the molten metal vortex.

摘要： A method of bonding a protective coating on a wear-exposed surface of a carbon tile comprises: applying onto the wear-exposed surface of the carbon tile at least one layer of a slurry of particulate refractory material suspended in a colloidal and/or inorganic polymeric carrier comprising a dispersion of colloidal particles and/or a solution of inorganic polymeric particles of binding metal oxide; and heat treating the slurry-applied layer(s) to consolidate the particulate refractory material in the binding metal oxide to form the protective coating. A hydrophobic carbon compound having a hydrophilic substituent, such as -OH, -SO3Na or -COOH, is used in the slurry as a bonding agent that bonds the binding metal oxide to the carbon tile by being bonded to the wear-exposed surface of the carbon tile and by having its hydrophilic substituent bonded to the binding metal oxide. Preferably, the protective coating comprises on the layer(s) containing the hydrophobic carbon compound one or more layers of refractory material which are substantially free of any elemental carbon or organic carbon compound.

摘要： A method and apparatus are disclosed for injecting vaporizable material, such as a vaporizable waste, into a molten bath. A gas is injected into the molten bath at a rate which is sufficient to cause the gas and the molten bath to form a gaseous dispersion. The gas component of the gaseous dispersion occupies a sufficient fraction of said dispersion to cause a significant portion of the vaporizable material, at a rate at which the vaporizable material is injected into the molten bath, to volatilize, combust or decompose during exposure to said gas component. A vaporizable material, such as a particulate solid or hazardous liquid waste, is injected into the gaseous dispersion at a rate which causes a significant portion of the vaporizable material to volatilize, combust or decompose during exposure of said vaporizable material to the gas component of said gaseous dispersion.
