摘要： An electrolytic cell for reducing a beryllium oxide in solid state, and a method for achieving this reduction, are provided. The electrolytic cell and method employ an anode, a cathode formed in part from beryllium oxide, and a molten electrolyte which includes cations of a metal that is capable of reducing beryllium oxide. The reduction process involves operating the cell at a potential that is above a potential at which the reducing cations in the electrolyte will deposit as a metal on the cathode.

摘要： Method and apparatus for continuously casting metal strip (20) of the kind in which a casting pool of molten metal (30) is formed in contact with a moving casting surface. By making the casting surface (16A) very smooth and inducing relative vibratory movement between the molten metal and the casting surface at selected frequency and amplitude, the heat transfer from the solidifying metal is dramatically improved. The casting surface has an Arithmetical Mean Roughness Value (Ra) of less than 5 microus and the induced vibratory movement preferably has a frequency of no more than 20 kHz. This enables improved casting productivity and also produced a marked refinement of the surface structure of the cast metal.

摘要： In twin roll casting of steel strip, molten steel is introduced into the nip between parallel casting rolls to create a casting pool supported on casting surfaces of the rolls and the rolls are rotated to deliver solidified strip downwardly from the nip. Casting surfaces are textured by a random pattern of discrete projections, which may have an average surface distribution of between 5 and 200 peaks per mm2 and an average height of at least 10 microns. In order to suppress chatter defects, the molten steel also has manganese content of at least 0.55% by weight and a silicon content in the range of 0.1 to 0.35% by weight. The strip is thus capable of moving away from the casting pool at a speed of more than 60 meters per minute without substantial high speed chattering defects.

Casting surfaces are textured by a random pattern of discrete projections at least some of which include peaks having a surface distribution of between 5 and 200 projections per mm2 and an average height of at least 10 microns. The random texture may be produced by grit blasting the casting surfaces on a substrate covered by a protective coating. Alternatively the texture may be produced by chemical deposition or electrodeposition of a coating onto a substrate to form the casting surfaces.
