摘　　要：连铸保护渣是连铸过程用于生产各类型钢种的重要、必需的功能材料,具有保温、防止钢液氧化、吸附杂质、润滑、改善传热等功效。连铸保护渣技术标准体系对指导行业制定保护渣相关标准有重要作用,目前国内外标准化组织已进行了相关标准研制,但未形成健全的标准体系,仍有一些关键、重要的标准急需研制。因此,本文基于连铸保护渣生产工艺、冶金应用、微观结构、信息化等领域的标准研制原理,围绕连铸保护渣从原料配制、生产加工、产品质量和结晶器应用等整个生命周期的各个环节,系统地开展连铸保护渣技术标准体系研究。基于以上研究,本文建立连铸保护渣产品类型、产品性能和技术标准体系的三维空间模型,构建连铸保护渣技术标准体系框架和标准体系明细表,归纳和梳理了20项行业标准,提出了拟研制的29项连铸保护渣标准,其覆盖了基础、产品、方法、质量、生产加工、信息化领域的国际标准、行业标准和团体标准,并对方法标准中拟研制的标准进行了比较分析。通过对连铸保护渣技术标准体系进行研究,为行业开展连铸保护渣标准研制提供技术支撑和奠定理论基础,对加快连铸保护渣的国际流通、产品认证、质量追溯有重要作用,对推动生产高质量钢种及特殊钢种技术开发有重要战略意义。Mold fluxes are an indispensable functional material that acted on the molten steel surface in the crystallizer for continuous casting, providing thermal insulation, preventing steel reoxidation, adsorbing or entrapping inclusions, lubricating steel strands, and controlling heat transfer. The technical standards system of mold fluxes plays an essential role in guiding the industry to formulate the technical standards of mold fluxes. At present, domestic and international standardization organizations have developed some relevant standards. However, a sound standards system has not yet been formed, and there are still some essential standards that urgently need to be developed. Therefore, based on the standardization principles in the fields of the production process, metallurgical application, microstructure, and information technology, this article systematically studied the technical standards of mold fluxes from each link of the whole life cycle, such as raw material preparation, production process, product quality and practical application. In this paper, a three-dimensional spatial model of the product type, product performance, and the corresponding technical standard system was also built. 20 published industry standards and 29 standards of mold fluxes to be developed were listed, covering international, industry, and group standards in the fields of foundation, product, method, quality, production processing, and information technology. Moreover, the standards to be developed were compared and analyzed. The technical standard system built provides technical support and a theoretical foundation to develop the standards of mold fluxes, promoting the circulation, certification, and quality traceability of mold fluxes. The above research has an important strategic significance to the production process optimization of high-quality and special steel grades.
