Damage Study of Heated Conveyor Rolls in Roller-hearth Furnaces for High-strength Steel Aluminum-silicon Coated Plates

摘要

论文强调了高强钢热冲压成形技术的重要性，以及辊底炉在其中的关键作用。通过分析氧化铝辊与AlSi涂层金属板可能发生的热化学侵蚀机制，实验测试记录了高温环境下的界面扩散和化学反应情况，探究了辊子与铝硅镀层的粘接和侵蚀规律。尽管炉辊涂覆材料有助于减轻侵蚀问题，但炉辊耗损和能耗利用仍具挑战。研究提出了多层箱式炉与辊底炉混合加热生产线的构想，为解决热化学侵蚀挑战提供新思路。这项研究深入分析了加热辊底炉的热化学侵蚀问题，并提出了混合加热生产线的解决方案，旨在提高生产线稳定性和能耗利用率。

Abstract

This paper emphasizes the importance of hot stamping and forming technology for high-strength steel and the key role of roller-hearth furnace in it. By analyzing the possible thermochemical erosion mechanisms of alumina rolls and AlSi coated metal sheets, experimental tests documented the interfacial diffusion and chemical reactions in high temperature environments, and explored the adhesion and erosion patterns of the rolls to the AlSi coatings. Although furnace roll coating materials help mitigate erosion problems, furnace roll depletion and energy utilization remain challenging. The study proposes the concept of a hybrid heating line between a multi-story chamber furnace and a roller-hearth furnace, which provides new ideas to address thermochemical erosion challenges. This study provides an in-depth analysis of the thermochemical erosion problem in heated roller-hearth furnaces and proposes a solution for a hybrid heating line aimed at improving line stability and energy utilization.
