摘要： Fusion cast refractories are formed by first displacing the air from the mold cavity with an inert, heavy gas, preferably argon. The molten fusion cast refractory is then poured into the mold cavity and allowed to solidify. This procedure minimizes the evolution of gases from molds which have an organic binder and thus reduces the formation of pores in the solidified refractory.

摘要： A method for the production of two-layer pipe casting is carried out in the following manner. First, a reaction chamber is filled with an initial mixture. Then, the reaction chamber with the initial mixture is set in rotation about its longitudinal axis whereupon the centrifugal acceleration of the reaction chamber is brought up to about 300 to about 1000 g. The initial mixture is then inflamed and centrifugal acceleration is gradually brought down to about 50 to about 100 g for a time period sufficient to enable combustion of the initial mixture as well as subsequent separation of the resultant melt into two layers, external and internal, until their solidification. The separation of the melt composed of the final products of combustion into two layers takes place under the action of centrifugal forces due to the difference in specific weights of said layers. In the course of crystallization of the pipe external and internal layers, as well as during their subsequent cooling, centrifugal acceleration is maintained constant.
摘要翻译：以下述方式进行双层管铸生产方法。首先，用初始混合物填充反应室。然后，将具有初始混合物的反应室围绕其纵向轴线旋转，由此使反应室的离心加速度达到约300至约1000g。然后将初始混合物发泡，并将离心加速逐渐降至约50至约100g，持续一段足以使初始混合物燃烧的时间，以及随后将所得熔体分成两层，外部和内部，直至他们的凝固。由最终的燃烧产物组成的熔体在离心力的作用下由于所述层的比重的差异而分离。在管道外层和内层结晶过程中，以及在随后的冷却过程中，离心加速度保持恒定。

摘要： Basic fused cast refractory with principal crystal phases of periclase and magnesium-spinel is made by adding nonfused oxidic inorganic grog particles to molten mass of the refractory as it is cast into a mold cavity, thereby resulting in increased modulus of rupture at temperature in the range of about 1340.degree.-1500.degree. C. and avoidance of shell formation. Molten mass has a composition consisting essentially (by weight) of 45-78% MgO, 0-30% Cr.sub.2 O.sub.3, 0-35% Al.sub.2 O.sub.3, 0-17% FeO + Fe.sub.2 O.sub.3, at least 82% MgO + Cr.sub.2 O.sub.3 + Al.sub.2 O.sub.3 + FeO + Fe.sub.2 O.sub.3, 1-8% SiO.sub.2, 0-2% CaO + BaO + SrO.sub.2, 0-10% TiO.sub.2 and 0-3% fluorine. Nonfused particles have a loss on ignition at 1000.degree. C. of less than about 0.5% by weight and an aggregate SiO.sub.2 content at least about equal to the SiO.sub.2 content of the molten mass forming the cast refractory. Grog particles are of a size (e.g., within the range of particles passing about 25 mm. sieve openings and retained by about 0.5 mm sieve openings) and in an amount (e.g., about 2.5 to 70% by weight of the cast refractory) sufficient to effect at least partial melting of and penetration into the particles by and resolidification with the cast molten mass so as to form a continuous coherent crystal structure throughout the solidified cast mass wherein discrete grog particles and remnants thereof (if any exist) are not optically identifiable.
