Method and equipment for producing cast stone by using titanium-containing blast furnace slag
The invention relates to the field of metallurgical and inorganic non-metallic materials, and discloses a method and production equipment for producing cast stone by using titanium-containing blast furnace slag. Titanium-containing high-aluminum slag solid waste resources are fully utilized, direct pouring and sealed pressure forming are carried out in the molten state, then crystallization heat preservation is carried out, the cast stone is formed, a nucleating agent and a tempering agent do not need to be added in the whole process, the crystallization capacity of the titanium-containing high-aluminum slag is matched with the sealed pressure means, the prepared cast stone is compact, and the cast stone quality is improved. The defects of a large number of shrinkage cavities and the like are avoided, and the characteristics of high hardness, wear resistance, compression resistance, low porosity, acid and alkali resistance and the like are achieved; meanwhile, the provided matched production equipment can be used for treating the titanium-containing high-aluminum slag generated by smelting the vanadium titano-magnetite on line, the production process is simplified, and the method is suitable for large-scale production.
本发明涉及冶金与无机非金属材料领域，公开了一种利用含钛高炉熔渣生产铸石的方法以及生产设备。本发明充分利用含钛高铝熔渣固废资源，在熔融状态下直接浇筑并密封加压成型，然后晶化保温形成铸石，整个工艺无需添加晶核剂和调质剂，利用含钛高铝熔渣自身晶化能力配合密封加压手段，使得所制备的铸石较为致密，避免造成大量缩孔等缺陷，并具有硬度高、耐磨、抗压、气孔率低、耐酸碱等特性；同时，所提供的配套生产设备可在线处理冶炼钒钛磁铁矿而产生的含钛高铝熔渣，生产工艺简化，适合大规模生产。
