<p>A method of thermal removal of barbs from metallic parts provides for a two-stage process. First a chamber is filled with a mixture of a gas fuel with air, the composition and the pressure of which are chosen so as to ensure burning-off of oils and evaporation of the moisture from the surface of the treated parts. Then the mixture is fired and the moisture present on the parts is evaporated and the oils are burnt off. After that, the combustion products are removed from the chamber which is then filled with a mixture of a gas fuel and oxygen and this mixture is fixed, the barbs on the parts thus being burnt off.</p> |
