摘要
通过Gleeble热模拟试验机对高硅高强钢热轧板进行了不同加热温度高温加热试验,模拟"一次氧化铁皮"生成,并对试样进行高温拉伸与空气喷气快冷,模拟实际生产时除鳞状态,考察残留氧化铁皮形貌与结构特点.发现:1200 ℃以上明显出现了氧化铁皮的液化情况,氧化铁皮剥离量大,1150 ℃氧化铁皮呈现较为平整形貌,剥离量少;在当前试验条件下,1150 ℃残留铁橄榄石层最薄,其残留氧化铁皮结构更易清除.
Abstract
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.
