Preparation process of ceramic spherical foundry sand with coal gangue as raw material
The invention relates to the technical field of foundry sand, in particular to the field of IPC C04B35, and more particularly relates to a preparation process of ceramic spherical foundry sand with coal gangue as a raw material. Comprising the following steps: step 1, proportioning coal gangue and auxiliary minerals to obtain a first mixture; 2, mixing the first mixture with water, and grinding into powder to obtain a powdery first mixture; step 3, sequentially carrying out pugging, honeycomb green body forming, drying, setting and high-temperature sintering on the powdery first mixture to obtain a second mixture; step 4, crushing and grading the second mixture to obtain ceramic powder; and 5, spheroidizing the ceramic powder in a high-temperature spheroidizing furnace through a high-temperature melt-blowing process, and feeding the spheroidized ceramic powder into a particle cooling and collecting system. The method has the advantages of comprehensive utilization of solid waste, energy conservation, emission reduction, low manufacturing cost and the like, and can be used for casting high-end castings.
本发明涉及铸造砂技术领域，尤其涉及IPC C04B35领域，更具体的，涉及一种以煤矸石为原料陶瓷球形铸造砂的制备工艺。包括以下步骤：步骤1：将煤矸石与辅助矿物进行配料，得到第一混合料；步骤2：将第一混合料与水混合，研磨成粉，得到粉状第一混合料；步骤3：将粉状第一混合料依次通过练泥、蜂窝状坯体成型、干燥、码坯，高温烧成，得到第二混合料；步骤4：将第二混合料经破碎、分级，得到陶瓷粉体；步骤5：将陶瓷粉体通过高温熔喷工艺，在高温球化炉中球化后，进入颗粒冷却收集系统，即得。具有固废综合利用、节能减排、制造成本低等优点，可用于高端铸件铸造。
