摘要
在马弗炉和Gleeble-3800型热模拟试验机上对高碳钢H82BJ进行了不同条件的氧化试验,采用OM、SEM等手段对氧化铁皮厚度和结构进行表征,结果表明:高碳钢氧化铁皮一般呈FeO和Fe_(3)O_(4)两层结构,氧化铁皮厚度和FeO的比例随温度的升高而增加;并且,随着冷速的提高,氧化铁皮厚度和FeO中共析组织Fe_(3)O_(4)相的比例逐渐降低。通过调整实际生产中的温度和冷却速度,得到了适合机械剥壳的氧化铁皮厚度和结构。
The simulated oxidation tests of high carbon steel H82 BJ were carried out on muffle furnace and Gleeble-3800 thermo-mechanical simulator and the thickness and phase composition of oxide scale for samples were characterized by OM,SEM.The results show that typical oxide scale on high-carbon steel mostly consists of FeO and Fe_(3)O_(4),the scale thickness and the thickness ratio of FeO/Fe_(3)O_(4) were increases with the increase of oxidation temperature,and the scale thickness and percentage of eutectoid Fe_(3)O_(4) from FeO phase were decreases with the increase of cooling rate.The thickness and structure of oxide scale suitable for mechanical descalability were obtained through adjusting the temperature and cooling rate in the actual process production.
