Research on Intermediate Frequency Induction Solution Treatment Furnace for Large-sized Welded Stainless Steel Pipe

摘要: 介紹了一種利用中頻感應加熱技術的大直徑不銹鋼焊管固溶處理裝置。通過該裝置，消除了不銹鋼焊管在成型、焊接過程中產生的應力以及焊縫兩側熱影響區(qū)，提高了不銹鋼焊管的耐腐蝕性能。重點介紹了針對目前生產不銹鋼焊管固溶處理較為合適的中頻頻率和電源功率，以及固溶處理裝置使用中的經驗和問題，并提出了較為簡單易行的解決辦法。

Abstract: Elaborated in the paper is a solution furnace employing the intermediate frequency induction technology for treatment of large-sized welded stainless steel pipes. This solution treatment system is capable of eliminating the stress and HAZ on both sides of the weld of the stainless steel pipe as generated during the forming and welding processes, and thus enhancing the corrosion resistance of the pipe. Focused on are issues such as the intermediate frequency rates and mains powers rather suitable for currently-used solution treatment process for welded stainless steel pipes, and experiences and problems concerning operation of the solution treatment systems, and some easy-to-do proposals for fixing the problems, and so on.
