Method of making a metallic, workpieces by oxygen cutting, oxygen cutting device and obtained metallic workpiece. |
摘要 |
<p>The workpiece is obtained by cutting a metal product (1) by oxygen cutting. An oxygen-cutting jet (4) is sent into a preheated cutting zone of the product (1). A peripheral sleeve (6) of additional gas is formed around the oxygen-cutting jet (4) so as to send into the cutting zone a coaxial double jet constituted by the oxygen jet (4) surrounded by the sleeve (6) of gas at a pressure less than 1 bar. The flow rate and the pressure of the cutting oxygen and of the additional gas are regulated independently. The invention also relates to an oxygen-cutting device for the implementation of the method and to the metal workpiece obtained. <IMAGE></p> |
