Recovery process of magnesia carbon brick waste
The invention relates to the technical field of smelting waste recycling, in particular to a magnesia carbon brick waste recycling process which comprises the steps that cleaning is conducted, specifically, steel slag impurities on the surface of magnesia carbon brick waste are cleaned; soaking in water: soaking the cleaned magnesia carbon brick waste in water; drying: drying the magnesia carbon bricks soaked in water in a kiln at the drying temperature of 180-250 DEG C; crushing: crushing the dried magnesia carbon bricks, wherein the crushing pressure is 3-4 MP; primary screening is conducted, specifically, the crushed particles are screened, the particles with the qualified particle size enter the next procedure, and the particles with the unqualified particle size return to the crushing procedure; mixing and grinding: carrying out mixing and grinding on granules with qualified particle sizes after primary screening; and secondary screening: the mixed and ground granules are subjected to secondary screening, the granules with qualified particle sizes are magnesia carbon brick regenerated materials, and the granules with unqualified particle sizes are returned to the mixing and grinding process. The process steps are simple, production equipment is simple, production is very easy to achieve, and damage to the real-particle aggregate can be reduced while the regenerated material with the target particle size is obtained.
本申请涉及冶炼废弃物再利用的技术领域，尤其涉及一种镁碳砖废料的回收工艺，包括清理：清理镁碳砖废料表面的钢渣杂质；泡水：清理后的镁碳砖废料在水中浸泡；烘干：泡水后的镁碳砖放入窑炉烘干，烘干温度180℃～250℃；破碎：对烘干后的镁碳砖进行破碎，破碎压力3MP～4MP；一次筛分：筛分破碎后的颗粒料，合格粒径的颗粒料进入下一步工序，不合格粒径的颗粒料返回破碎工序；混碾：对一次筛分后粒径合格粒径的颗粒料进行混碾；二次筛分：对混碾后的颗粒料进行二次筛分，合格粒径的颗粒料为镁碳砖再生料，不合格粒径的颗粒料返回混碾工序。本申请工艺步骤简洁，生产设备简单，生产上极易实现，并且在获得目标粒径再生料的同时能够减少“真颗粒”骨料的受损。
