Abstract
The processes of oxygen cutting of metals are investigated in terms of raising their productivity. The methods of activation of oxidation are considered on the basis of construction and analysis of the equation of kinetics of the oxidation processes. It is suggested that the equation of the oxidation kinetics should be used in a general system of equations which model the heat and mass transfer processes occurring within the cut zone. The three-dimensional dynamic problem of heat and mass transfer was solved numerically using the explicit difference diagrams. Results of numerical and full-scale experiments are given. They confirm reliability of the computer models when used instead of the full-scale experiments for optimization of the oxygen cutting technology.
Keywords: oxygen cutting, attack angle, productivity, cut zone, oxidation kinetics, computerized experiments, numerical solution, difference diagram
