Embodiment 1
[0047] A kind of iron and steel hot slag mineral wool, its raw material composition mass percentage is:
[0048] Liquid blast furnace slag 70%
[0049] Conditioner 30%
[0050] The particle size of the conditioning material is 40-80 mesh; the conditioning material is composed of albite and silica sand.
[0051] A method for preparing iron and steel hot slag mineral wool (for the process flow, see image 3 ), the steps are:
[0052] ①Introduce the hot blast furnace slag directly into the primary melting zone of the slag furnace 2 through the slag tank 1, place the hopper 3 above the junction of the slag tank 1 and the slag furnace 2, and install the conditioning material in the hopper 3, and the conditioning material Together with the hot blast furnace slag, it enters into the initial melting zone of the slag furnace 2 (see figure 1 ). Such as figure 2 As shown, the cross-section of the slag tank 1 is semicircular, and the slag tank 1 is a composite structu...
