Abstract

In this study, the thermochemical erosion of the heating roller hearth furnace conveying roller in the hot stamping production line was studied. Firstly, the application of hot stamping forming technology for high strength steel and the key position of roller hearth furnace in this technology are introduced. Then the possible thermochemical erosion mechanism between the aluminum oxide roll and the metal plate with AlSi coating is discussed. The experimental results show that the interface diffusion and chemical reaction between alumina roll and AlSi coating occur at high temperature, leading to adhesion and erosion. In addition, the erosion degree of furnace rolls in different furnace temperature ranges was also studied through experiments, and the relationship between furnace body length and furnace roll consumption was discussed. Although the use of furnace roll coating material can partly alleviate the problem of thermochemical erosion, the consumption of furnace roll and the improvement of effective energy consumption utilization are still challenging. Finally, this paper discusses the possibility of the combination of multi-layer box furnace and roller hearth furnace to form a mixed heating production line.
