Abstract

1460411 Thermic lance KUBATEC KUNST: STOFF-UND BAUTECHNIK AG and E BRANDENBERGER 21 Jan 1975 [23 Jan 1974] 2673/75 Heading F4T A thermic lance comprises a steel jacket tube and between eight and sixteen steel core wires inserted in the tube to leave space for the passage of oxygen, wherein the jacket tube has an outer diameter of 3 to 10 mm., the diameter of the wires is 1 mm., the silicon content of the wires is less than that of the jacket and the carbon content of the wires is greater than that of the jacket.
