冷轧硅钢废水处理现状、问题及对策浅析
就冷轧硅钢废水处理生产中面临的主要问题进行分析,从技术角度及运行管理角度提出工艺优化升级改进措施及应对策略;同时从后续深度处理,逐步实现零排放目标的角度进行探讨,为冷轧硅钢废水减量化、出路乃至废水零排放提供一些思路。 The main problems in the wastewater treatment process of cold-rolled silicon steel lines are analyzed and process upgrading measures and optimization strategy are put forward from both technical and management views.At the same time,downstream deep treatment to gradually achieve the target of zero discharge is discussed,to provide some ideas for reduction or even zero discharge of wastewater from cold-rolled silicon steel lines.
取向硅钢含铬无机绝缘涂层的研究进展
绝缘涂层可以有效提高硅钢片的耐蚀、耐腐、磁、绝缘等性能，因此取向硅钢涂装绝缘涂层是取向硅钢生产过程中重要的一环。本文对取向硅钢含铬无机绝缘涂层以及氮化铬涂层的性能优缺点进行了介绍，并对国内无机含铬取向硅钢绝缘涂层及氮化铬涂层的研究现状进行了综述。最后对未来含铬无机绝缘涂层的研发方向进行了展望。 Insulation coating can effectively improve the corrosion resistance of silicon steel sheet, such as corrosion, magnetic, insulation performance, thus oriented silicon steel insulation coating is the important part of oriented silicon steel production process. In this paper, the inorganic insulation coating oriented silicon steel containing chromium and chromium nitride coating performance advantages and disadvantages are introduced.In addition, the research status of insulation coating and chrom...
