MODELLING THE CHEMICAL COMPOSITION PROCESS CONCERNING FORMATION OF METALS FROM MANUAL ARC SURFACE ON THE BASIS OF THE ELECTRODE COATING CHARGE COMPONENTS CLASSIFICATION

The topic of the article is modelling the process of forming the chemical composition of metal during manual arc surfacing based on the classification of the components of the electrode coating charge. The subject of research is the chemical composition of the metal obtained as a result of the manual arc surfacing process. The article discusses a mathematical model of manual arc surfacing, based on the classification of the components of the electrode coating during manual arc surfacing, describing the process using equations that take into account the transition of elements from the rod and electrode coating to the slag and metal baths, as well as their losses and gains due to burning out, oxidation and reduction. The research methods are based on: mathematical modelling of physical and chemical processes occurring during manual arc surfacing allows to establish of the correspondence of the developed model to real processes based on determining the convergence of experimental and calculated values. The proposed technique makes it possible to evaluate the composition of the deposited metal during surfacing with coated electrodes and the transition coefficients of the elements.
