The invention provides a preparation process of an environment-friendly baking-free brick. The preparation process comprises the following steps: selecting raw materials, pretreating incineration furnace slag, carrying out multi-stage compositing treatment, carrying out sand making treatment, carrying out brick making sand pretreatment, mixing and stirring materials, carrying out static pressure molding and carrying out maintenance treatment. The incineration furnace slag is used as a main raw material, so that the production cost for preparing the environment-friendly baking-free brick can bereduced, and the problem of environmental pollution caused by long-term retention of the incineration furnace slag in an open environment can be solved; in addition, recyclable metal contained in theraw material incineration furnace slag can be effectively screened out through a multi-stage magnetic separation process, so that the economic benefit brought by the incineration slag is improved, the engineering performance of the prepared environment-friendly baking-free brick can be improved, and the environment-friendly baking-free brick can obtain better strength; fly ash generated in the multi-stage crushing treatment process is collected and recycled, the economic benefit of the incineration furnace slag can be improved again, and meanwhile pollution of the fly ash to the environment and on-site brick making workers is reduced.
本发明提出一种环保免烧砖的制备工艺，包括以下步骤：选择原料、焚烧炉渣的预处理、多级复合处理、制沙处理、制砖沙的前处理、混合拌料、静压成型和养护处理；本发明通过使用焚烧炉渣作为主要原材料，可以缩减制备环保免烧砖的生产成本，同时可以解决焚烧炉渣长期保留在开阔环境内造成的环境污染问题，并且通过多级磁选过程可以有效的筛选出原材料焚烧炉渣内含有可回收金属，提高了焚烧炉渣带来的经济效益，同时可以提高制成的环保免烧砖的工程性能，环保免烧砖可以获得更好的强度，通过对多级破碎处理过程中产生的飞灰进行收集回收，可以再次提高焚烧炉渣的经济效益，同时减少了飞灰对环境以及现场制砖工人的污染。
