Purpose of the development: The exothermic mixture is superheated to obtain high-speed steel of oxides of the alloying elements or powders at their recovery and minimum aluminum debinding alloying elements.

Recommended application field: The invention can be implemented in the tool production in the manufacture of cutting tools and repair production welding and highly consistent recovery of the detail of guide members machines (hardware) and others.

Advantages over analogues: Invented metallothermic mixture allows unlike existing formulations synthesize metallothermal alloy containing increased amounts of tungsten, cobalt, vanadium, silicon, manganese, molybdenum, which come from the ligature. In addition, the synthesis based on the developed metallothermal mixture is fully autonomous process, independent of complex and expensive equipment, the major sources of energy and has a high speed and performance of the whole process (the time of combustion of the mixture lasts 20-30 seconds). Analogues of the composition of the mixture for the synthesis of instrumental metallothermic high-speed steels abroad not.

The development stage readiness: Ready for application

Technical and economic effect: Technical and economic indicators of working with for the promotion, implementation and implementation (technical solution of the present invention (a) domestic analogue (b); foreign analog (c)): 1 The economic effect of the introduction, c.: 1.5 million. UAH. in year (s); 1.0 million. UAH. (b); no (c). 2 Technological preparation of production, years: 1.0 (a); 1.5 (b); no (c). 3 rate of return: 0.1 (a); 0.5 (b); no (c). The use of exothermic mixture to produce thermite speed steels economically feasible in cases where an urgent need to (in seconds) to produce a liquid high speed steel in non-specialized repair shops and even a "field" conditions. Features exothermic mixture also had a positive impact on the properties of the synthesized steel, and allow the use of thermite cast high speed steel for the cutting process, showing better properties than the alloys produced by industrial technologies.

Description of the development:
()
Exothermic mixture contains Fero aluminum thermite, oxides of alloying elements or powders of these elements, and is characterized in that Fero aluminum thermite is composed of iron oxide in the form of waste blacksmith and rolling production and aluminum in the form of flour aluminum chips, and as alloying elements, oxides or powdered metals (chromium metal or carbon ferrochrome FH65-7A, silicocalcium S40L10, ferrosilicon FS65Al3,5, ferovanady (a 75%), carbon, molybdenum, tungsten oxide) for the corresponding ratios of the components. The degree of development of the technical solutions of the present invention is in the process of using experimental design, technological preparation for the introduction of mass production will take 1 year. The advantages of using an exothermic mixture of this composition lies in the fact that the exothermic mixture will allow highly effective with minimal burning of alloying elements and for a short period of time to receive high speed steel in the conditions of production facilities, unsuitable for conventional methods of melting alloys, as well as an opportunity to carry out welding pieces and parts alloys HSS in repair shops and workshops.
