Abstract
MODELING OF COMPOSITION OF THE POWDERED WIRE FOR OVERLAYING WELDING ACTIVE FACES OF THE FEEDER WITH OPTIMUM HARDNESS Hasylo Yu.A., Ivchenko P.S., Kamel H.I., Dudnikov O.V. Abstract While in service there is an obtunding of active faces and deterioration the joint a rotor and the cage a rotor feeder of Swedish firm “Camear”, it is bundled to contact chafing of connecting surfaces in the conditions of a high pressure (squeezing) microvolumes working edges under the influence of cutting of a woody cod and other firm subjects (electrodes, a wire, bolts, a bosk and other ectogenic subjects). Active faces a rotor and the feeder cage cease to carry out the function and thus positive allowances which leads to emersion critical an expense of a meadow from a feeder and their preschedule removal from maintenance increase. Using different materials at overlaying welding of active faces a rotor and the cage we can reach increases in service life of feeders. In the conditions of a world economic crisis, use a valuable material for overlaying welding of active faces a rotor and the cage of Swedish firm “Camear” has under itself no volume substantiation, in the further work we will observe recoveries by means of materials and sampling of a material which more all meets the requirements is made — has sufficient hardness, strength and impact strength. Paper is devoted working out a tailored composition of a powdered wire with maintenance of the maximum hardness. For the purpose abbreviation volume of explorations at sampling system of an alloy building welded metal is spent multifactorial correlation analysis. To raise impact strength welded metal it is possible as a result of alloying by its cerium. It is known, that a microalloying became cerium leads to raise of plastic properties metal. For the purpose of check agency cerium on impact strength there were welded samples with different its contents. With increase in a mass corpuscle of cerium from 0,05 % to 0,1 % value of impact strength and hardness grow. At the further increase in the contents of cerium (from 0,1 % to 0,2 %) impact strength continues to raise, but hardness considerably drops. For the purpose of reception the optimum mechanical properties necessary for a material of active faces a rotor and the cage, cerium contents in welded metal have restricted within 0,06—0,12 %. By results of exploration it is possible to draw a leading-out which material 50ХНМ which by means of mathematical planning (multifactorial correlation analysis) were in addition alloyed (increased contents of carbon, manganese and chromium) the most effective and inexpensive materials which can be used for restoration to overlaying weldings of active faces of details a feeder is.
