Laddle preheating  [ Return towards  Applications  ]

The objective of this operation is to stock in the refractory the calories that are necessary to avoid, or better limit, the metal temperature fall due to the metal transfer into the ladle ; this operation is necessary in order to have a metal that is at the suitable pouring temperature.

Today with the new techniques of ladle metallurgy (degassing, desulphurisation,....) high temperatures of preheating are frequently required. The energy cost of this operation has consequently grown and, in the same time, more attention is given to it.

The evolution in refractory materials allows the use of oxy-fuel burners to realise the ladle preheating, with very good performances and with all the advantages, characteristic of the oxy-combustion.
