Preparation method of silicon oxynitride-silicon carbide composite brick for low-oxygen copper rod production
The invention relates to the technical field of composite brick preparation, in particular to a preparation method of a silicon oxynitride-silicon carbide composite brick for low-oxygen copper rod production, which comprises the following steps: S1, preparing a first raw material, S2, preparing a second raw material, S3, preparing a first mixture, and S4, firing the silicon oxynitride-silicon carbide composite brick. According to the method disclosed by the invention, the first raw material and the second raw material are combined in the mold, so that the problems of peeling and slag falling easily caused by erosion of kiln gas and frequent high-temperature aging of the inner-layer brick of the kiln are solved, and the thermal insulation performance of the silicon oxynitride-silicon carbide composite brick is improved; by adding the composite sintering aid, combination of silicon nitride can be promoted, sintering of the composite brick blank is denser, the mechanical property of the silicon oxynitride-silicon carbide composite brick is effectively improved, and the breaking strength of the silicon oxynitride-silicon carbide composite brick is enhanced.
本发明涉及复合砖制备技术领域，具体是涉及一种低氧铜杆生产用氧氮化硅‑碳化硅复合砖的制备方法，包括以下步骤：S1、制备第一原料，S2、制备第二原料，S3、制备第一混合料，S4、烧制氧氮化硅‑碳化硅复合砖；本发明方法通过第一原料与第二原料在模具中组合，解决了窑炉内层砖块因受窑炉气体的侵蚀以及频繁高温老化易出现的剥落和掉渣情况，并且提高了氧氮化硅‑碳化硅复合砖的保温隔热性能；通过添加复合烧结助剂能够促进氮化硅的结合，使复合砖坯料的烧结更加致密化，并且有效提升氧氮化硅‑碳化硅复合砖的力学性能，增强氧氮化硅‑碳化硅复合砖的抗折强度。
