DESIGNING THE PRODUCTION OF SEGMENTS OF PROTECTIVE STRUCTURES BY MODERN METALLURGICAL TECHNOLOGIES

Summary. The development of new technologies for the construction of protective structures of multifunctional purpose reflects the current need to improve measures for the protection of civilian human and material resources (and double -purpose), as well as to increase defense capability through structures, buildings, storage and shelter. The article concerns research and design development of metal structures for the field of construction of such structures, armor, and relevant to the technologies of erection of fortifications and armor obstacles. Construction structures made of metal compared to structures made of stone, reinforced concrete and trees have significant advantages that are proposed to be implemented by the use of a cast metal segment weighing up to 50 kg for the erection of protective structures. This solves the problem, which is the simple installation of such structures from segments, even in the field, and the possibility of variation of the structure of structures, for example, an arbitrary increase in their addition of segments or the formation in the structure of holes. Such a segment causes a slight collapsing ability to relax the structures. The segment is simple to pour in numerous even small foundry shops or sites, which can be converted to new casting technologies and strengthening of heat treatment for increasing the ratio of strength to segment mass. Also, by analogy with known patents, a variant of the design of the heat -processed segment of cast iron or steel with high mechanical properties due to the effect of self -aggregation during loading, which consists in partial absorption Increases metal strength in the deformation zone. For the production of lightweight segments, it is recommended to use the Lost Foam Casting Process.

Key words: protective structures, segment, castings, cast iron, heat treatment, Lost Foam Casting Process.
