Abstract

The positioning system for lance for injecting a fuel/oxygen mixture into the smelting zone of a smelting oven for metal production, especially cast iron or alloy production using a cupola furnace, comprises a housing (1) with a slide chamber (5). The lance (2) is mounted in this on a spiral spring suspension (3) and can be moved axially by a guide rod (4)
