    Method of removal of slag deposits from the bottom of a

    Slag deposited on the bottom of a steel making furnace especially a soaking pit for steel ingots is difficult to remove. To enable this to be done while the furnace is hot it is now proposed to supply a substance e.g. ferro-silicon which lowers the melting point of the slag and a substance which reacts exothermically to initiate melting of the slag.
