Method for preparing foamed ceramic by taking lead smelting fuming slag as raw material and foamed ceramic prepared by method
The invention relates to a preparation method of foamed ceramic using lead smelting fuming slag as a raw material and the foamed ceramic prepared by the method, and belongs to the field of building materials, and the preparation method comprises the following steps: (1) drying, grinding and screening the lead smelting fuming slag; (2) fully and uniformly mixing with pulverized coal, reacting according to a carbon proportioning ratio, a reduction temperature and reduction time, heating to a melt separation temperature after the reaction is finished, preserving heat, cooling along with a furnace after the reaction is finished, and separating to obtain metal iron and melt separation residues; (3) melting the obtained melt separation residues, and after the melting is finished, carrying out water quenching, drying, grinding and screening to obtain basic glass powder; (4) adding auxiliary materials, a fluxing agent and a foaming agent into the obtained basic glass powder, and carrying out ball milling and mixing; and (5) loading the powder into a corundum crucible, paving and compacting, and firing. According to the method, metal iron can be recycled while the reduction residues are modified to prepare the foamed ceramic, and the prepared foamed ceramic has the advantages of being light, good in heat insulation performance, high in residue utilization rate and high in product additional value.
一种以铅冶炼烟化渣为原料的发泡陶瓷的制备方法及以该方法制备的发泡陶瓷,属于建筑材料领域,制备方法包括:(1)铅冶炼烟化渣烘干、研磨和筛分;(2)与粉煤充分混匀,按照配碳比、还原温度、还原时间进行反应,结束后升温至熔分温度保温,结束后随炉冷却,分离得到金属铁和熔分残渣;(3)得到的熔分残渣进行熔制,结束后,水淬,烘干,研磨,筛分,得到基础玻璃粉末;(4)得到的基础玻璃粉末加入辅料、助熔剂、发泡剂,球磨混料;(5)粉料装入刚玉坩埚中,铺平压实,进行烧制。该方法将还原残渣改性制备泡沫陶瓷的同时,还能够回收金属铁,制备的泡沫陶瓷具有轻质、隔热性能好、残渣利用率高、产品附加值高的特点。
