Abstract
To permit smaller cross section of thermal lances, in which a plurality of core wires are inserted in a jacket tube with space between the core wires and the jacket tube for the supply of oxygen, the relative dimensions of the elements of the lance are selected as follows: The outer diameter of the jacket tube is between 3 mm and 10 mm; 8 to 16 core wires are used; the ratio of the diameter of the space to form a duct for oxygen to the overall diameter of material is between 1 : 4 to 1 : 10; the ratio of core wire diameter to the wall thickness of the jacket tube is between 1 : 0.7 to 1 : 2; and, to hold the wires in place, the jacket tube is formed with a bulge or undulation adjacent the end formed with a connection for the supply of oxygen, the bulge or deformation being so formed that, essentially, there is no reduction in cross section. In a preferred form, the wall thickness of the tube, and the cross section of the core wires are all, about, 1 mm and about 10 to 11 core wires are used, the clear diameter of the jacket tube being about 4 to 6 mm.
