摘要： A process and control system for controlling a rotary calcining kiln (10) having a feed material inlet (12) material to be calcined, a calcined product outlet (13) and a high temperature zone in which said material is calcined, the high temperature zone being movable within the rotary calcining kiln (10) according to changes in operational control variables of the rotary calcining kiln. The process comprises measuring temperatures within the rotary calcining kiln at various positions spaced from each other along the rotary calcining kiln in a region overlapping a predetermined desired position for the high temperature zone, and adjusting the control variables to move the high temperature zone to the desired position when the high temperature zone deviates from the desired position. In the process, the temperatures are measured by thermocouples (Th) having thermocouple junctions (26) protected by heat and abrasion resistant sheaths (27), preferably made of alumina/silicon carbide ceramics, positioned within the rotary calcining kiln.

摘要： A method and apparatus are disclosed for continuously drying, preferably with agglomeration and/or coating and sizing, and separating a solid product from a liquid feed material, especially bauxite slurry which passes through a very sticky phase during drying, without significant encrustation of the equipment used. The method comprises: spraying a liquid bearing solid material upwardly into a drying zone, feeding a drying gas into the drying zone from below the spraying liquid in substantially parallel flow, removing the mixture of the drying gas and entrained dried particles from the drying zone, separating the entrained dried particles from their mixture with the drying gas, returning the separated dried particles to the drying zone, and collecting the dried particles, characterized by arranging for the formation of a slower moving boundary layer within the feeding of the drying gas, through which boundary layer dried particles are allowed to fall under gravity to be collected, and by collecting the dried particles continuously from below the spraying liquid.

摘要： The invention relates to a process for producing anhydrous magnesium chloride involving the following combination of steps: drying impure salt containing hydrated magnesium chloride; establishing a solution of the hydrated magnesium chloride; removing insoluble impurities; reacting the solution of hydrated magnesium chloride at substantially ambient pressure and at a temperature between 10 DEG and 60 DEG C by feeding it into an ammonia saturated very low boiling point alcohol solution and in the presence of ammonium chloride while maintaining the last-mentioned solution saturated in ammonia thereby to form a precipitate of ammoniated magnesium chloride; separating the precipitate and heating it to obtain anhydrous MgCl2 and ammonia for recycling. The process can result in the production of very pure anhydrous mangesium chloride suitable, for example, for the production of metallic magnesium.

摘要： This invention relates to a process for the extraction of alumina from alumina-containing solid material, particularly the alumina-containing ores known as bauxite. The process comprises: a) providing the material in the form of a slurry (101) in an alkaline solution having a concentration of free caustic therein sufficient at the temperature reached in step (c) to dissolve alumina values, b) classifying (6) the slurry into a fine particle fraction and a coarse particle fraction, c) heating the fine particle fraction (105) to a temperature sufficient to dissolve at least some of the alumina values therein with consequential reduction in the free caustic concentration in the liquid phase of the fine fraction slurry, and d) combining the coarse particle fraction (109) from step (b) with the free caustic-depleted slurry liquid from step (c) at a temperature higher than that reached in the step (c) so as to dissolve at least some of the alumina values in the coarse particle fraction.

摘要： Cooling of metal strip (16) in a single or multistand cold rolling line by applying coolant liquid only to the lower surface of the strip (16), and removing the liquid therefrom, after each, or between successive roll stands (11a, 11b, 11c). The liquid is delivered, at each cooling locality, at low pressure through a plurality of slots (32) each extending transversely beneath and across the full width of the strip (16), the slots (32) being spaced apart along the path of the strip (16) and generally being oriented to discharge the coolant liquid toward the strip lower surface at an angle of greater than 90 DEG to the direction of strip advance. Coolant removal is effected by directing one or more liquid knives (52a, 54a, 60a) against the strip lower surface between the plurality of slots (32) and the next downstream roll stand in the line, at a location at which the strip (16) is trained around a hold-down roll (56).

摘要： In the Bayer process for producing alumina from bauxite, the efficiency of the red mud separation procedure can be substantially improved if the flocculant (45) normally used is diluted with a clear process liquor (43c) obtained from a prior, the same or a subsequent settling or washing step and mixing this diluted flocculant solution with the red mud slurry (41) to be separated. This permits the use of less flocculant than conventional methods, the avoidance of diluting with water and the production of a thickened slurry of increased mud concentration.

摘要： A cast composite material having little spinel therein is formed from a mixture having a composition of from about 5 to about 35 volume percent of aluminum oxide reinforcing particles and from about 95 to about 65 volume percent of a molten matrix alloy. The matrix alloy is an aluminum-based alloy containing from about 0.15 to about 3 weight percent magnesium and a sufficient amount of strontium to reduce or entirely suppress spinel formation. The strontium content is from about 0.1 to about 2 weight percent of the matrix alloy. This composition is mixed to wet the matrix alloy to the particles and to distribute the particles throughout the volume of the molten matrix, while minimizing the introduction of gas into and retention of gas within the mixture. The wetted mixture is cast into molds or forms.
