You may use high temperature resistant ceramic blankets to fix the leak. These have to be clipped to the wall or joints using heat-resistant pins which are hooked or welded to the metal lining (outer steel shell) of the furnace by making a small hole through the insulation layers.

I completely agree with muralidar. Seal the holes with high temp furnace cement and back them up with reinforced high temp steel.
