铝板带轧制用轧辊的质量与寿命

论述了铝板带轧制用轧辊的质量与寿命，指出轧辊寿命取决于其制造质量与使用情况。热轧工作辊的裂纹损坏和冷轧工作辊有效淬硬层过浅是两大突出问题。严格的入厂质量检验和定期消除应力回火是保证轧辊使用寿命的关键措施。

Quality and Working Life of Roll for Aluminum Strip Rolling

Quality and working life of roll for rolling aluminum strip are discussed.Roll working life depends on its fabrication process and how to use it.The principal problems with respect to roll working life are cracking at the surface of roll for hot-rolling and that effective zone of quench-hardening of roll for cold-rolling is too narrow. Strict factory entering examining and regular stress-relieving tempering are key precautions to ensure roll working life.
