Abstract: An apparatus and method of storing a great length of continuously advancing elongate metallic material in a temperature controlled accumulator (40, 50) is disclosed to enable greater line speeds by exposing a greater length of material to the heat treatment. Several embodiments are disclosed in which heated cylindrical accumulator apparatus (40, 50) are used to store a multiplicity of wraps (45) around fixed or rotating cylinders (44, 51) which are maintained at the desired temperatures.

Abstract: In an in-line refining vessel (50) having one or more submerged porous plugs (20) for bubbling gasses through the molten metal (47) to stir the slag layer (46) covering same, an oxygen lance (40) for effectively oxygenating the melt from above. A plurality of such devices may be used in a single vessel.

Abstract: In a continuous casting plant of the wheel and belt type, the grooved casting wheel 11, and the associated belt or band 12, are tilted laterally so that the plane of rotation is inclined. As a result, the cast bar 30 emerges from the casting wheel without any horizontal surface, and passes to bar preparation machinery with this orientation, prior to being rolled.

Abstract: A method of continuously casting a molten metal in a casting means to obtain a solidified cast bar at a hot-forming temperature, passing the cast metal at a hot-forming temperature from the casting means to a hot-forming means, and hot forming the cast bar into a wrought product by a two-stage reduction of its cross-sectional area while it is still at a hot-forming temperature, including, in the first stage, the step of forming a substantially uniform subgrain or cell structure in the outer surface layers of the cast bar by a selected small amount of deformation of the cast bar in its as-cast condition prior to the second stage in which substantial reduction of its cross-sectional area forms the wrought product.

Abstract: Disclosed is a surge control method and apparatus for a combustion air blower used with a metal melting furnace which includes a variable restriction on the blower inlet regulated by a pressure sensing means near the blower outlet.

Abstract: Apparatus for and a method of hot rolling cast metal under hydrostatic pressure to achieve a substantial reduction in cross-sectional area without cracking and the improved wrought product thereof characterized by decreased segregation, better grain structure and absence of cracking.

Abstract: An apparatus for substantially eliminating deflection of cantilevered work roll shafts and work rolls of a cantilevered type rolling mill comprising adjustable work roll support rollers which rotatably brace work rolls at points approximately 180 angular degrees from the metal stock and work roll contact area.

Abstract: Solution heat treatment of a rapidly advancing intermediate metallic product (26) is accomplished by preheating the product in a first zone (27) by conventional means, a great length of the product is maintained at the desired temperature in a second zone (36), and the heated product is quenched in a third zone (40) in a special apparatus (25), before further processing.

Abstract: A method and apparatus for heat treating and especially annealing of elongate metallic materials such as wire wherein the wire (24) given a longer length exposure to complete the heat treatment of the wire at higher line speeds. This is accomplished either by adding a heated storage chamber (41) holding a great length of wire (24) in sequence with conventional or modified annealing apparatus, or by substitution of a special apparatus (100) for the existing conventional annealing apparatus.

Abstract: A fail safe air wipe for use with a casting band cleaning system wherein cleanser and rinsing agent used to clean the casting band of a continuous casting machine is removed from the band by mechanical wiping means when pneumatic supply to pneumatic wiping means falters to prevent explosion which may result from contacting the molten material being cast with the cleanser or rinsing agent.

Abstract: Disclosed is an apparatus for and a method for more uniform and rapid cooling of molten metal, which is continuously cast into a wheel-band machine, by dispersing a relatively small amount of coolant from the periphery of a band presser wheel onto the continuous metal band at the point where the molten metal first contacts said band, with the unexpected beneficial effects of increasing the cast bar temperature and greatly reducing the amount of inverse segregation on the band-side surface of the resulting cast bar.

Abstract: Disclosed are a method of and apparatus for radiation pyrometric temperature measurement of a continuous cast metal bar. Cast bar advancing from a continuous casting machine is continuously monitored for temperature without contacting the cast bar with any apparatus by applying a layer of soot onto the surface of the bar, detecting infrared radiation emitted from the sooted area, converting the detected radiation into a temperature signal, displaying the temperature, and completely removing the soot from the cast bar before it enters a rolling mill.

Abstract: Disclosed are apparatus for and a method of continuously trapping slag during molten copper transfer wherein a refractory slag trap comprising baffles traps slag particles by providing areas of non-uniform flow within the molten copper melt thereby causing all constituents having a specific gravity less than that of molten copper to rise to the surface of the molten copper and form agglomerates which can be easily separated from the copper by a pseudodeconting procedure or by other manual means.
