Conclusions
The refractory lining of the cooled part of the stack eroded before the end of the campaign and the blast furnace was operated for 18 months without this masonry.
In the furnace the refractory impregnated with the dustlike and gaseous products of the melting materials, viz., the ferrous compounds of the ore in the charge, oxide vapors of the alkali metals, and the components of the slag melt. The chemical conversions in the refractory result in the erosion of the lining of the stack. The refractory lining of the noncooled part of the stack remains in a satisfactory condition and may serve for 10 years or more without major patching.
Hydrogen and soot carbon are not primary causes of the failure of the stack lining, but it would be difficult at this stage to give an unequivocal answer to the question of their contribution to the process of erosion.
It was established that sphalerite deposits are confined to the heat cracks in the refractory and the joints in the masonry of the refractory lining of the shaft.
