Steel ladles are preheated after relining to stabilize the lining material and to avoid thermal shock during the first tapping after relining. The preheating procedure is associated with high-energy consumption and the emission of unburned hydrocarbons.
The unburned hydrocarbons include a considerable amount of polycyclic aromats, known as being strongly carcinogenic. The projects aims are the optimisation of the preheating-procedure, the reduction of energy consumption, the optimisation of the combustion and the development of measures to reduce emissions. Especially the reduction of emissions will improve the working quality considerably.
