铝箔轧机工作辊的研制

Manufacture of aluminum-foil work roll

针对铝箔轧机工作辊高硬度、高硬度均匀性和高加工精度要求,通过控制辊坯电渣重熔和锻造、调质处理、最终淬火、磨削加工等关键工序质量,最终达到辊面硬度100～105 HSD,硬度均匀性±1 HSD,≥98 HS深度16 mm,满足了产品设计要求,可以替代进口轧辊。

This paper focuses on the research and manufacture of the work roll used for Al-foil mill. Normally the work roll is required of high hardness, high uniformity of hardness, and high precise as well. By controlling of the electro slag remelting and forging, thermal refining, final quenching and grinding, eventually, roller surface hardness reaches 100 - 105 HSD and hardness uniformity be of ±1 HSD, and acuity 98 HS depth is 16 mm. The manufactured aluminum-foil work roils meet the design requirement and can replace the imported work roils.
