Abstract:
The invention relates to a plasma cutting arrangement having at least one plasma cutting torch which is formed by a torch body, an electrode and a nozzle having a nozzle bore. An outer contour AK of the plasma cutting torch is present in cross-section with respect to a longitudinal axis which is aligned perpendicular through the nozzle bore. A smallest spacing between the longitudinal axis extending through the center of the nozzle bore of the nozzle and the radially outer margin of the outer contour AK is observed in at least one axial direction and corresponds at a maximum to ¾ of the length of a largest spacing d between the central longitudinal axis extending through the center of the nozzle bore of the nozzle and the radial outer margin of the outer contour AK. A smallest spacing c can also correspond to a maximum of ⅜ of the length of a largest distance b between two points of the outer margin of the outer contour AK whose virtual straight connection line extends through the central longitudinal axis extending through the center of the nozzle bore of the nozzle.

Abstract:
In the present pelletizing apparatus, the induration of iron ore concentrate pellets is achieved in a tunnel furnace heated by plasma torches, wherein the generation of by the conventional iron ore pelletizing processes is reduced by using electricity powered plasma torches instead of burning natural gas, heavy oil or pulverized coal in burners, thereby reducing considerably industrial pollution of the atmosphere.
