碳化鉻NM360耐磨鋼管上壓出痕跡的原因及處理方法

更新時間:2020-03-24 19:28點擊次數:
壓痕是指利用鋼線,通過壓印,在碳化鉻NM360耐磨鋼管上壓出痕跡或留下供彎折的槽痕。
        一、壓痕形成的原因
        (1)周期性壓痕是由于成品孔或成品前孔、矯直輥、出口輥動導板、導輥等粘有凸起物;
       (2)異物掉在碳化鉻耐磨復合管上,經軋后脫落;
       (3)耐磨管在運送、保管過程中與硬物碰壓或碳化鉻耐磨復合管本身相互硌壓。
        二、壓痕消除方法
        (1)在生產碳化鉻耐磨復合管中定期檢查軋件、軋槽、矯直輥和輥動導板,發現問題及時處理;
        (2)軋制時防止異物掉在碳化鉻耐磨復合管上;
        (3)吊運NM360耐磨鋼管要平穩,碳化鉻NM360耐磨鋼管的包裝要平齊,捆扎要牢固,堆放底腳要墊平。
