| titleOfInvention | Steel slag treating method |
| abstract | The invention provides a steel slag treating method comprising the following steps of: directly mixing thermal-state revolving furnace steel slag with blast furnace slag in an arc furnace in proportion, adjusting the molten slag in the furnace into a proper temperature by virtue of the arcing of the arc furnace, and stirring the molten slag by virtue of arc disturbance, so that acidic oxide and basic oxide in the molten slag are sufficiently reacted with each other; reacting free calcium oxide and free magnesium oxide in the raw steel slag with silicon dioxide component and low-calcium calcium silicate in the blast furnace slag to generate safe calcium silicate and magnesium silicate, quenching the molten slag to form glass-state solid slag which is higher in hydration reactivity and free of short-term or long-term inflation harm, and further finely grinding the solid slag into slag powder which can be safely used for related building material as the blast furnace slag. According to the method, the damage caused by the free calcium oxide and free magnesium oxide in the steel slag can be removed, and a basis is provided for the whole use of the steel slag. The heat energy of the thermal-state molten slag can be sufficiently used, so that the energy source can be saved, the energy consumption can be reduced, the cost can be reduced, and the discharge of CO2 can be reduced, and the method is extremely high in social meaning and economic meaning. |
