The invention belongs to the technical field of solid waste resource utilization, and discloses a method for preparing a sintering-free artificial synthetic board from nickel smelting slag. The method comprises the following steps: stirring and mixing nickel smelting slag, a fine-particle-size particle filler, a liquid filler and auxiliary materials to prepare a mixture, then placing the mixture in a mold frame, distributing to form a plate-shaped structure, vacuumizing the interior of the mold frame, performing mutual movement under the resultant action of vacuum force and hammer slapping force to fill and press to form a board, and finally, carrying out curing, demolding, cooling and fixed-thickness polishing and grinding on the board to obtain the the artificial synthetic board. According to the invention, a complete material solid body is formed by combining the large-particle-size nickel smelting slag with the fine-particle-size particle filler and the liquid filler in a vacuum and vibration mode, and the obtained artificial synthetic board has good mechanical strength. According to the method, recycling of the nickel smelting slag is achieved, and good environmental protection benefits and economic benefits are achieved.
本发明属于固废资源化利用技术领域，公开了一种采用镍冶炼炉渣制备免烧结人造合成板材的方法。将镍冶炼炉渣与细粒径颗粒填充料、液体填充剂及辅料经搅拌混合，制成混合料，然后置于模框中布料，形成板状结构，将模框内抽真空，在真空力和重锤拍击力的合力作用下相互运动填充压制形成板材，最后将压制后的板材进行固化、脱膜、冷却、定厚抛磨，得到所述人造合成板材。本发明采用大粒径镍冶炼炉渣与细粒径颗粒填充料及液体填充剂进行结合的方式，通过真空+振动的形式形成完全的材料实心体，所得人造合成板材具有良好的力学强度。本发明实现了镍冶炼炉渣的资源化回收利用，具有良好的环保效益和经济效益。
