热轧时钢铁材料高温氧化铁皮的研究进展
|
摘要
钢在热轧过程中发生氧化反应产生大量氧化铁皮,这不仅浪费钢铁资源而且影响其表面质量和耐蚀性,有效地控制氧化铁皮的厚度和结构是迫切需要解决的问题。本文主要从钢中的合金元素和热轧工艺两方面入手,介绍了钢在不同热轧条件下产生氧化铁皮的形态结构和形成机理。重点介绍了合金元素和终轧温度、卷取温度及冷却速度对氧化铁皮的厚度和结构的影响,并对各种条件下氧化铁皮的显微结构和厚度进行了分析,从而能够对氧化铁皮的生成和其引起的各种表面缺陷进行有效的控制。
In the hot rolling process, steel is oxidized and a large number of oxide iron scales are produced. This not only wastes iron and steel resources, but also affects their surface quality and corrosion resistance. It is an urgent problem to effectively control the thickness and structure of iron oxide scales. Beginning from alloying elements in the steel and hot-rolling process,the morphology, structure and formation mechanism of oxide iron scale produced by steel under different hot rolling conditions were introduced. The effects of alloying elements and finish rolling temperature, coiling temperature and cooling rate on the thickness and structure of iron oxide scale were mainly introduced. The microstructure and thickness of oxide iron scale under various conditions were analyzed, so that the formation of oxide iron scale and the surface defects caused by them can be effectively controlled.
