Product description : 

Oxygen lancing tubes are used for opening furnace tap holes i.e. tapping a furnace
When the desired steel composition and temperature has been reached, the furnace tap hole is opened through a combination of drilling and tapping using oxygen lances. Lances are coupled to a high pressure oxygen supply, the end of the lance is ignited and through careful and skillful manipulation, the tap hole clay which can be up to 800mm thick is effectively burnt away, facilitating the pouring of the molten metal for further processing.
