| Popis: | The effect of the out-of-furnace treatment of metallurgical coke with aqueous solutions of inorganic substances on changes in the coke reactivity index (CRI) and coke strength after reaction (CSR) was studied. It was found that the treatment of coke with an aqueous solution of sodium tetraborate (Na2B4O7 · 5H2O) exerted the greatest effect on an improvement in the qualitative characteristics (CRI and CSR). Changes in the values of CRI and CSR of metallurgical coke as functions of the concentration and amount of the solution of sodium tetraborate were studied. It was found that the greatest improvement in the values of CRI and CSR of coke was reached upon treatment with a 7.5% solution of Na2B4O7 using 45 l per ton of coke. In this case, the coke hot strength increased by 18.8 rel %, whereas the reactivity index decreased by 13.2 rel %. |
