Conclusions Experiments using radioactive isotope phosphorus-32 show that during the fettling period the slag penetrates into the fettling made from PMP powder, slagged with scale at the top, down to a depth of 40–60 mm, and into the fettling made from a mixture of ground magnesite powder and scale only to 15–20 mm; the tentative (effective) coefficients of diffusion are respectively equal to 0.4·10−3 and 0.7 ·10−5 cm2/sec. The calculated values for these coefficients characterize the combination of the effects of temperature gradient, capillary forces, and the diffusion itself, etc. The prolonged action of slag on the fettling during the finishing period of the furnace leads to a considerable change in the chemical and phase compositions of the fettling, and creates conditions for intensive wear during the melting process.
