<p>PURPOSE:To obtain an inexpensive binder for sintering substitutable for expensive quick lime or quick-setting cement by mixing ferromanganese slag and/or silicomanganese slag with steel making slag cooled rapidly from a molten state and one or more kinds of substances such as CaSO4.2H2O as an exciting agent in the form of powders. CONSTITUTION:This binder for sintering is a powdery mixture of inexpensive ferromanganese slag and/or silicomanganese slag with steel making slag cooled rapidly from a molten state and one or more kinds of substances selected among CaSO4.2H2O, CaO, Ca(OH)2, CaCO3, NaOH and Na2CO3 as an exciting agent. The effect of the binder on a sintered product is comparable to that of conventional expensive quick lime. Blast furnace slag and steel making slag as by- products from the iron industry are recycled and ferromanganese slag and silicomanganese slag as by-products from a ferroalloy maker are utilized, so the binder is profitable.</p> |
