-
摘要: 在以斜轧穿孔的方式穿制冷轧-冷拔用毛管时,管坯的热穿孔工序是高合金钢钢管生产的关键。本文总结了在Ф76mm穿孔机上生产GH30、GH36、GH39和GH140等高温合金管的管坯热穿孔工艺及操作经验。Abstract: Billet hot piercing is a key process in the production of superalloy steel pipes when billet are to be pierced by a cross rolling pierced shells are to be supplied to cold drawing and cold rolling. The billet hot piercing process and its operation experiences for the production of pipes of superalloy steels GH30, GH36, GH39 and GH140 on a Ф76mm piercer are summed up.
