Conclusions
A method of production by pneumatic ramming of rammed blocks of high-alumina mixtures for the lining of shaped floors of heating furnaces with a walking floor in which round or hexagonal billets are heated was developed.
By the mass-spectrometric method it was established that in thermal decomposition of the phosphate binder in the proposed ramming mixtures the phosphorous-containing mixtures are liberated in the form of PO and PO2 molecules. The products of the reaction of orthophosphoric acid with clay are characterized by the lowest resistance to thermal decomposition, which is an indication of the necessity of limiting its content in the ramming mixture to eliminate the danger of phosphorous contamination of the metal being heated.
