衡钢90t电炉除尘系统设计

Design of the dust removal system of the 90t electric arc furnace Hengyang Steel

介绍了衡钢大管坯项目90t超高功率电炉除尘系统的设计、工艺流程、自动化控制和使用除尘系统值得注意的关键技术包括除尘器过滤布袋滤料的材质、清灰技术和烟气温度.衡钢大管坯项目90t超高功率电炉除尘系统已投运6个多月,加料、冶炼熔化、强吹氧脱碳和出钢过程中,除尘效果良好,系统运行稳定.电炉正常运行的情况下,可不需人工干预,完全实现自动控制,与一炼钢除尘系统相比优势十分明显.实践表明,该系统的投入运行,彻底改善了电炉炼钢对环境造成的污染,提高了生产技术水平,收到了很好的经济效益和社会效益.

The key technology about the design of 90 t Ultra High Frequency Arc Furnace’s dedusting sys-tem, technical flow, and automation control was introduced. And the material of dedusting filter bag, cleaning dust technics and the temperature of the gas were analyzed. The dedusting system of the 90 t UHP arc furnace in Hengyang Steel-making Co. was run into use for six months. It worked well and stable. When the arc furnace worked normally, it could work automatically. It was more advantage than the first steel making factory. In fact, because of the use of the dedusting system, it improved the pollution to the environment and improved the pro-ductivity, so good economy and social benefit were got.
