Presented are the results of the use of metallurgical wastes as constituents of welding fluxes. On the basis of fine particle gas purification in aluminum production, a carbon fluoride additive (FD-UFS) has been designed for welding fluxes which allows for manufacturing of steel constructions of northern execution with improved mechanical properties of welded joints. It is shown that the introduction of FD-UFS to fluxes AN-348, AN-60 and AN-67 increases the range of the required mechanical properties. Composition and manufacturing technology has been developed for a new welding flux with application of slag from silicomanganese production. Fractional composition of the flux has been selected. A comparative assessment of the mechanical properties of the developed flux with widely used flux AN-348 (GOST 9087-81) showed that the mechanical properties of the new flux are much greater. It has been determined that the introduction of flux additive FD-UFS in the amount of 2-8 % significantly increases the value of toughness KCV at a temperature of minus 20 °C.

This paper uses transmission electron microscope technology, studies microcosmic structure’ s feature of BN fiber, clarifies existing crystal structure’s state of BN fiber during its producing and transform course. It is studied that BN fiber has a sound mechanical properties, which most of crystalline phase is turbine layer phase and whose nitrogen is high and size is small .During the course of BN fiber’s producing, adding suitable tension from axial can promote directional arrange of BN fiber’s surface crystalline grain and put forward the improving direction of manufacturing technology in order to improve materials’ mechanical properties. BN fiber(indicated by BNf) is a kind of new inorganic material. Because of its fine stable, corrosion-resisting, anti-oxidant properties and high ability of absorbing neutron and so on, it is attached more and more importance and it get constant development and usefulness. BNf and ceramics, metal, various compound materials made of resin material can be used in metallurgy, electron, aviation etc science and technology fields. But the intensity of BNf and its elasticity modulus are lower than basic fundamental material. When BNf’s compound material get fine properties above mentioned, the mechanics properties of the material will drop. So its application degree will be limited to a certain extent. In order to improve and raise BNf’s mechanics properties, this essay makes use of electron micro analytical technology to study its microcosmic structure and mechanics properties, providing scientific basis for designing reasonable manufacturing technology.

The article presents the results of a study of the effects of the fractional composition of quartzite on the physical and mechanical properties of a fired shard of dinas refractory masses. As a result of the study of their chemical-mineralogical, fractional compositions and physicochemical characteristics, it was found that for the development of the composition of refractory dinas masses, it is necessary to use fractions of fine grinding of quartzite.

Carbon-fluorine containing additive for AN-348A, AN-60 and AN-67 fluxes was developed. Application of the additive reduces the gas content of the weld as well as its contamination with oxide non-metallic inclusions and improves the complex of required mechanical properties and toughness (especially at low temperatures).
