控冷工艺对热轧盘条氧化皮耐腐蚀性的影响
Influence of Control Cooling Technology on the Corrosion Resistance of Iron Scale on Hot-rolled Wire Rod
摘要
Abstract
In order to improve the surface quality of steel scale on wire rod, the influence of the cooling rate and the cooling temperature on the corrosion resistance of iron oxide scale on hot-rolled wire rod was investigated.The scale composition was analyzed primarily through XRD.The scale surface feature, the thickness and the tightness were observed through SEM.The anti-corrosive performance of steel scale was observed through accelerated corrosion tests.The results have indicated that the exorbitant temperature results in thick iron scale and crack, and the low temperature results in thin iron scale without protection value.The tight steel scale can be formed with rapid cooling, and the content of Fe2O3 in the iron scale decreases when the content ratio of Fe3O4 to FeO increases.This enhances the properties of the iron scale.The iron scale is thick with slow cooling.关键词
