Embodiment 1
[0025] Propose a kind of preparation technology that solid waste silico-manganese slag produces mineral wool in the present embodiment, comprises the following steps:
[0026] S1: Prepare the tempering material: select an appropriate amount of nepheline and fly ash, add the nepheline and fly ash into a high-speed mixer for stirring treatment, and obtain the conditioning material;
[0027] S2: Mixing treatment: introduce the silicomanganese slag into the feeding pool through the slag ditch, and add the tempering material in S1 into the feeding pool, and fully mix;
[0028] S3: introducing the mixture prepared in S2 into a slag furnace to obtain a high-temperature solution, and adding the high-temperature solution to the roller in the centrifuge to form raw cotton.
[0029] In this embodiment, in S1, the mass percentage of nepheline is 70%, and the mass percentage of fly ash is 30%. In S1, the speed of the high-speed mixer is 1000r / min, and the stirring time is set to 20min. Th...
