    Manufacturing Process and Equipment of Φ720 mm Pilger Pipe Mill

    • 摘要: 介紹了華菱衡陽(yáng)鋼管(集團(tuán))有限公司新建Φ720mm周期軋管機(jī)組的工藝流程與平面布置,主要設(shè)備組成、特點(diǎn)和基本參數(shù)。該機(jī)組既能使用連鑄坯又能使用多邊形鋼錠生產(chǎn)特大直徑高精度高鋼級(jí)鋼管。該機(jī)組采用的先進(jìn)喂料器不但能提高軋制速度,降低勞動(dòng)強(qiáng)度,還能使荒管的壁厚和外徑精度顯著提高。

       

      Abstract: Described in the article are the main aspects of the newly-built large-sized Φ720 mm Pilger pipe mill line located at Hengyang Valin Steel Tube (Group) Co.,Ltd.,including the manufacturing process flow and the plant layout,and composition,features and basic parameters of the main equipment. The plant is capable of producing extra-large-sized, hi-precision and hi-grade steel tubes with CC billets or polygonal ingots. The stat-of-the-art feeding system as employed by the Pilger mill is capable of not only ensuring higher rolling speed and less labor intensity,but also getting the W.T. and O.D. tolerances considerably improved.
