Compositions have been developed for nonshrinking vibrocast thermally insulating light refractory concretes with densities
of 1.0, 1.3, 1.5, and 1.8 g/cm3 for temperatures of use up to 1400°C. The structure and properties have been examined for the concrete of density 1.3 g/cm3.

Secondary aluminum waste products, and processes that occur during heating and mineral formation on introducing fine periclase
powder into the composition of waste products are studied. It is demonstrated that secondary aluminum production waste may
be used as a raw material for synthesizing aluminomagnesia spinels.

Results of an experimental study of the aerodynamics and spray density distribution of a liquid dispersed by an airstream atomizer inside a drying chamber. Velocity components of the drying agent and their radial distributions as a function of the distance from the spray plane are determined. Relationships for the distribution of dispersed liquid inside the drying chamber are derived. Interactions between the drying agent and the product in the drying chamber are analyzed. 相似文献

The operation of linings of sections of heating furnaces of old and new designs is considered. Specifications for periclase-chromite mortar produced by the Pervoural'sk New Pipe Plant are worked out. The behavior and structural transformation of the heated mortar are investigated.Translated from Ogneupory, No. 11, pp. 29–31, November, 1994. 相似文献

The method of coprecipitation of components was used to obtain disperse powders of tetragonal zirconium dioxide stabilized by Y2O3, Yb2O3 and a combined additive (Y2O3 + CaO + MgO). The technological parameters of the processes of synthesis and preparation of initial ZrO2 powders intended for ceramics with elevated strength parameters are proposed. 相似文献

Conclusions A new method is proposed for determining the slag resistance of refractories with lever apparatus which is qualitative.The new technique permits the specific features of the destruction of refractories by slags to be determined, and explains the mechanism of this process by mineralogical analysis and by describing the external appearance of the changed specimens.Data on the changes in the specimens during tests and the compositions of the zones will be given in the next article.Data obtained by the new method show that the slag destruction of refractories accelerates with time. 相似文献

The problem is considered of taking account of heterogeneity in the individual radiosensitivity in evaluating the radiation risk of the origin of a disease in a group of persons subjected to the radiation action. Mathematical models are described for the estimation of the radiation risk of the origin of the disease with and without regard for heterogeneity. The use of the described method is demonstrated with an example of the estimation of the risk of the origin of radiation-induced diseases from the class of “solid cancers” among the persons taking part in the liquidation of consequences of the accident at the Chernobyl’ Atomic Power Station (CAPS) in the years 1986–1991. It is shown that the heterogeneity disregard leads to understated estimates of the radiation risk of the origin of radiation-induced solid cancers. The effect is investigated of the length of the latent period in the origin of radiation-induced “solid cancers” in taking account of heterogeneity. 相似文献
