Method for synthesizing fused mullite and fused corundum-mullite by using coal gangue as raw material
The invention discloses a method for synthesizing electro-fused mullite and electro-fused corundum-mullite by taking coal gangue as a raw material, which comprises the following steps: crushing the coal gangue, adding a carbon material and scrap iron or iron oxide, and electrically melting in an electric arc furnace to obtain the electro-fused mullite raw material and the electro-fused corundum-mullite raw material. The mullite and corundum-mullite refractory raw materials are prepared from the solid waste coal gangue as the raw material through the electric smelting method, the coal gangue is large in storage capacity and low in price, the electric smelting method is a preparation method integrating mineral separation and synthesis, the process is simple, and industrialization is easy to achieve. The mullite and corundum-mullite are prepared by using the coal gangue as the raw material through an electric melting method, so that high-value recycling of the coal gangue is realized, and the method has important significance.
本发明公开了一种以煤矸石为原料合成电熔莫来石和电熔刚玉‑莫来石的方法，包括将煤矸石破碎后配入碳素材料、以及铁屑或铁的氧化物，在电弧炉中电熔后得到电熔莫来石原料和电熔刚玉‑莫来石原料。本发明以固体废弃物煤矸石为原料通过电熔法制备莫来石和刚玉‑莫来石耐火原料，煤矸石储量大且价格低廉，且电熔法是集选矿与合成为一体的制备方法，工艺简单，易于实现工业化。以煤矸石为原料通过电熔法制备莫来石和刚玉‑莫来石实现了煤矸石的高值资源化，具有重要意义。
