The invention provides a
rotary furnace cooling agent and a manufacturing method thereof. The cooling agent is a carbonic and ferreous conglomeration which mainly takes iron scale, carbonic
waste material and ferreous
waste material as raw materials, and prepared by additionally adding
caking agent into the raw materials. The weight percentage of the main chemical compositions of the cooling agent meets the following condition: the carbon content is 5-25%, the content of TFe is more than or equal to 50%, the content of S is less than or equal to 0.50% and the content of P is less than or equal to 0.50%. The manufacturing method comprises: the wet materials in the carbonic
waste material and the ferreous waste material are firstly dried and crushed by a
crusher, and then enters a blending
machine to be mixed together with the dry materials such as the iron scale and the like; the mixture is added with the
caking agent to be evenly mixed, and the mixed material is sent into a mixing mill and then into a twin-roller ball press
machine to be pressed into conglomeration; the pressed conglomeration is screened by a sieving
machine, and the qualified screened conglomeration can be sent into a dry furnace to be dried, so that the finished product conglomeration can be obtained. The
rotary furnace cooling agent completely uses the waste materials generated in the steel production, and can be used for replacing the common waste steel to be applied in
smelting of a
rotary furnace, so that no special reduction
plant is needed for use, the process flow is short, the cost is low, the using method is flexible, the adding quantity is large, the
recovery rate is high, the field operation is seldom affected, the economic benefit and the
environmental protection benefit are remarkable, and the promotion and application values are excellent.
