低碳涂铝钢经过薄板坯连铸连轧技术制造（S.K. Paul, U. Ahmed, and G.M. Megahed
2009年10月29号提交，2010年4月27号修订）
Low-carbon Al-killed hot rolled strips for direct forming, cold rolling, and galvanizing applications are proced from the similar chemistry at Ezz Flat Steel (EFS) through thin slab casting and rolling (TSCR) technology.
用于直接成型，冷轧，以及镀锌应用的低碳热轧条与埃智钢铁公司的扁钢薄板坯连铸连轧技术有着相似的化学处理过程。
The desired mechanical and micro structural properties in hot bands for different applications are achieved through control of hot rolling parameters, which in turn control the precipitation and growth of AlN.
通过控制热轧参数，并相应地控制沉淀物以及氮化铝的增长，能够获得热扎带的预期的机械和微结构性能，用于不同的应用。
Nitrogen in solid solution strongly influences the yield strength (YS), ctility, strain aging index(SAI), and other formability properties of steel.
固溶体的氮严重影响抗屈强度，延展性，应变指数以及钢的其他成型性能。
The equilibrium solubility of AlN in austenite at different temperatures and its isothermal precipitation have been studied. To achieve the formability properties for direct forming, soluble nitrogen is fixed as AlN by coiling the strip at higher temperatures.
我们已经研究过在不同温度的奥氏体氮化铝的溶解度以及等温过程的沉淀物。为获得用于直接成型的成型性能，在高温下将钢条盘成螺旋形，填充可溶性氮作为氮化铝。
For stringent cold forming, boron was added below the stoichiometric ratio with nitrogen, which improved the form ability properties dramatically.
为了冷成型，将硼以理想配比值与氮进行配比，这很大程度上提高了成型性能。
The requirements of hot band for processing into cold rolled and annealed deep drawing sheets are high SAI and fine-grain microstructure.
用于加工成高指标以及粒状结构的冷轧以及退火的深冲压板的热轧钢的要求
Higher finish rolling and low coiling temperatures are used to achieve these.
未获得以上目的，需要更高的轧制以及低卷取温度。
Fully processed cold rolled sheets from these hot strips at customer send have shown good formability properties.
从这些热条钢完全加工而成的冷轧板，客户反馈说有很好的成型性能。
Coil break marks observed in some coils ring uncoiling were found to be associated with yielding phenomenon.
在一些盘卷上我们观察到了卷裂的印记，这关联到屈变现象。
The spike height (difference between upper and lower yield stresses) and yield point elongation (YPE) were found to be the key material parameters for the break marks.
尖峰的高度（上部和下部的屈服应力的差异）以及屈服点延伸是导致破裂印记的主要的材料性能。
Factors affecting these parameters have been studied and the coiling temperature optimized to overcome the problem.
影响这些参数的因数已被研究，我们会将卷取温度最优化来克服这个问题。
