High temperature peeling test and analysis of iron oxide scale on high silicon and high-strength steel
High temperature heating tests were conducted on hot-rolled plates of high silicon and high-strength steel at different heating temperatures using a Gleeble thermal simulation testing machine.The formation of"primary ox-ide scale"was simulated,and the samples were subjected to high-temperature tensile testing and air jet rapid cooling to simulate the descaling state during actual production.The morphology and structural characteristics of residual oxide scale were investigated.Discovery:There is a significant liquefaction of iron oxide scale above 1200 ℃,with a large amount of iron oxide scale peeling off.At 1150 ℃,the iron oxide scale presents a relatively flat morphology with less peeling off;Under current experimental conditions,the residual iron olivine layer at 1150 ℃ is the thin-nest,and its residual oxide scale structure is easier to remove.
