Abstract

The invention relates to a method for preparing microlite by utilizing high-temperature molten slag during manganese alloy melting, belongs to the technical fields of metallurgy and inorganic non-metal materials, and provides the method, which is capable of efficiently utilizing the molten slag and heat energy, for preparing the microlite by adopting the high-temperature molten slag during the manganese alloy smelting through casting molding. The technical scheme adopted by the invention is operated through the following steps: a, discharging the high-temperature molten slag discharged by a manganese alloy smelting furnace into a tank furnace for clarifying and homogenizing; b, pouring clarified and homogenized slag liquid into a fireproof material mold, quickly curing and demolding; c, quickly delivering a demolded green body into a roller furnace, crystallizing, annealing and cooling, thus obtaining microlite bricks. The method provided by the invention is widely applied to preparation of the microlite.

Description

technical field [0001] The invention relates to a method for preparing microcrystalline stone by utilizing manganese alloy smelting high-temperature slag, and belongs to the technical field of metallurgy and inorganic non-metallic materials. Background technique [0002] Ferromanganese alloy slag is the slag discharged from manganese ore smelting ferromanganese. In the production of ferromanganese alloy, the discharge temperature is 1400~1550℃, and the slag content per ton is 1260~1180×10 3 kJ sensible heat. At present, the water quenching method is mainly used to make the water quenching slag to be piled up or used to manufacture cement, bricks, and heat-preserving silicate materials, etc., but the utilization rate and the added value of utilization are low. In addition, the water-quenched slag not only cannot recycle the latent heat of the slag, but also consumes a large amount of water resources and pollutes the environment. [0003] Microcrystalline stone, also known a...
