摘要: 介紹了衡鋼大管坯項目90t超高功率電爐除塵系統的設計、工藝流程、自動化控制和使用除塵系統值得注意的關鍵技術包括除塵器過濾布袋濾料的材質、清灰技術和煙氣溫度.衡鋼大管坯項目90t超高功率電爐除塵系統已投運6個多月,加料、冶煉熔化、強吹氧脫碳和出鋼過程中,除塵效果良好,系統運行穩定.電爐正常運行的情況下,可不需人工干預,完全實現自動控制,與一煉鋼除塵系統相比優勢十分明顯.實踐表明,該系統的投入運行,徹底改善了電爐煉鋼對環境造成的污染,提高了生產技術水平,收到了很好的經濟效益和社會效益.Abstract: 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.
