Abstract
The article discusses the use of a self-propagating high-temperature synthesis of SHS ofsolid chemical compounds – it is a new technological process that possible to obtain a materialwith a given structure based on carrying out an exothermic reaction of interaction of reagents inthe combustion regime. The influence of cold deformation and intermediate annealing underSHS conditions on the structure, magnetic and mechanical properties of low-carbon steel is determined.The use of magnetic coercimetric control possible to control changes in the structureand mechanical properties of during technological cycle for low-carbon welded wire in productionconditions.
Highlights
Technical progress involves the introduction of new technologies for the manufacture of welding wire which is used for welding and for surfacing
It is established that the industrial drawing of wire rod caused a change in mechanical properties, grain size, coercive force, and after annealing under SHS conditions the relative number of special boundaries increased
The results of the study of the microstructure at the stages of wire production The finely fibrous structure is the result of elongation and deformation of grains during metal extraction, which is confirmed by the high value of coercive force Hc = 9.1 A/sm is 10.06 μm
Summary
Technical progress involves the introduction of new technologies for the manufacture of welding wire which is used for welding and for surfacing. For the manufacture of welding wire requires a quality workpiece, it should not consist of segments and gaps and must comply with the requirements of regulatory documentation. The state standard 2246-70 sets requirements for the chemical composition of wire 08G2S. Alloying elements such as vanadium V, tungsten W, aluminum Al, and a number of other alloyed wire 08G2C is usually not alloyed. Standards allow a content of up to 0.01% nitrogen. This hardware is used for welding, and for surfacing
