A method for heating metal articles wherein supply of burning gas, formation of gas-air mix in mixer with its following ignition, diffusion of oxidizer to flame zone and its thermal effect on article take place. Besides that, after supply of burning gas division of gas flow to separate jets is performed, at that formation of gas-air mix in the mixer takes place through ejection of oxidizer from atmosphere and following ejection from 4 to 12 % of oxidizer from peripheral zone to the central zone of the mixer. |
