1.Introduction 1.介紹The precipitation and growth of aluminum nitride in low carbon Al-killed steel is one of the fundamental metallurgical processes that affect the final microstructure and properties (Ref 1). 氮化鋁的析出和生長(zhǎng)是低碳鋁鎮(zhèn)靜鋼最基本的冶金過(guò)程，它影響最終的金相組織和性能。The microstructure of steel evolves during hot rolling and cooling process. 熱軋及冷卻過(guò)程中鋼的金相組織的演變。The various important factors, which affect the microstructure of the steel, are dissolution of AlN during heating and soaking, strain-induced precipitation of AlN during hot rolling, interpass recrystallization, austenite grain coarsening, finish rolling temperature (FRT), and cooling of the strip.影響鋼金相組織的各種重要因素是：加熱及均熱過(guò)程中氮化鋁的溶解、氮化鋁在熱軋過(guò)程中的應(yīng)變誘導(dǎo)析出、層間再結(jié)晶、奧氏體晶粒粗化、扎制結(jié)束溫度和鋼帶的冷卻。 The evolution of grain size has been shown (Ref 2) to be different in low-carbon steel than that of other steels.低碳鋼晶粒大小的演變與其它鋼不同。 Thin slab casting and rolling (TSCR) of low-carbon steel has some distinguished characteristics, such as finer microstructure.連鑄連軋低碳鋁鎮(zhèn)靜鋼擁有卓越的性能，例如出色的金相組織。 Much faster cooling rate and rapid solidification (Ref 3) in association with liquid core reduction result in finer grains in thin slabs as compared to conventional thick slabs.與傳統(tǒng)的厚板相比，薄板冷卻快速、凝固快速和液核少。 This initial austenite grain size of slab plays an important role for controlling the final microstructure of the strip.這個(gè)初始奧氏體晶粒尺寸對(duì)最終鋼帶的金相組織控制有重要作用。 During casting, some aluminum nitrides also precipitate in thin slabs before entry into the tunnel furnace and may not dissolve during heating and soaking (Ref 4) at 1150°C for about 22 min.在鑄造期間，有一些氮化鋁在進(jìn)入隧道爐之前在薄板里析出，析出的氧化鋁在加熱及均熱（1150°C ，22 分鐘）期間可能不會(huì)分解。 These fine precipitates restrain the growth of recrystallized austenite grains, which significantly affect the final microstructure.這些細(xì)小的析出相抑制了再結(jié)晶奧氏體晶粒的增長(zhǎng)，從而影響了最終金相組織。Further, during hot rolling process some amount of fine AlN precipitates at different stages because of strain and decrease in temperature.而且在熱軋過(guò)程期間的應(yīng)變及降溫也會(huì)使氮化鋁析出。 These precipitates inhibit austenite grain growth by pinning grain boundaries leading to refining of austenite and hence ferrite grains.這些析出的氮化鋁抑通過(guò)限定邊界來(lái)制奧氏體的增長(zhǎng)，從而細(xì)化奧氏體晶粒和和鐵素體晶粒。

Effect of Hot Rolling Process on Microstructureand Properties of Low-Carbon Al-Killed Steels熱軋工藝對(duì)于低碳涂鋁鋼的微觀結(jié)構(gòu)以及性能的影響。Produced Through TSCR TechnologyS.K. Paul, U. Ahmed, and G.M. Megahed(Submitted October 29, 2009; in revised form April 27, 2010)低碳涂鋁鋼經(jīng)過(guò)薄板坯連鑄連軋技術(shù)制造（S.K. Paul, U. Ahmed, and G.M. Megahed2009年10月29號(hào)提交，2010年4月27號(hào)修訂）Low-carbon Al-killed hot rolled strips for direct forming, cold rolling, and galvanizing applications are produced from the similar chemistry at Ezz Flat Steel (EFS) through thin slab casting and rolling (TSCR) technology. 用于直接成型，冷軋，以及鍍鋅應(yīng)用的低碳熱軋條與埃智鋼鐵公司的扁鋼薄板坯連鑄連軋技術(shù)有著相似的化學(xué)處理過(guò)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. 通過(guò)控制熱軋參數(shù)，并相應(yīng)地控制沉淀物以及氮化鋁的增長(zhǎng)，能夠獲得熱扎帶的預(yù)期的機(jī)械和微結(jié)構(gòu)性能，用于不同的應(yīng)用。Nitrogen in solid solution strongly influences the yield strength (YS), ductility, strain aging index(SAI), and other formability properties of steel.固溶體的氮嚴(yán)重影響抗屈強(qiáng)度，延展性，應(yīng)變指數(shù)以及鋼的其他成型性能。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. 我們已經(jīng)研究過(guò)在不同溫度的奧氏體氮化鋁的溶解度以及等溫過(guò)程的沉淀物。為獲得用于直接成型的成型性能，在高溫下將鋼條盤(pán)成螺旋形，填充可溶性氮作為氮化鋁。For stringent cold forming, boron was added below the stoichiometric ratio with nitrogen, which improved the form ability properties dramatically. 為了冷成型，將硼以理想配比值與氮進(jìn)行配比，這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. 用于加工成高指標(biāo)以及粒狀結(jié)構(gòu)的冷軋以及退火的深沖壓板的熱軋鋼的要求Higher finish rolling and low coiling temperatures are used to achieve these. 未獲得以上目的，需要更高的軋制以及低卷取溫度。Fully processed cold rolled sheets from these hot strips at customer send have shown good formability properties. 從這些熱條鋼完全加工而成的冷軋板，客戶反饋說(shuō)有很好的成型性能。Coil break marks observed in some coils during uncoiling were found to be associated with yielding phenomenon. 在一些盤(pán)卷上我們觀察到了卷裂的印記，這關(guān)聯(lián)到屈變現(xiàn)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（上部和下部的屈服應(yīng)力的差異）以及屈服點(diǎn)延伸是導(dǎo)致破裂印記的主要的材料性能。Factors affecting these parameters have been studied and the coiling temperature optimized to overcome the problem.影響這些參數(shù)的因數(shù)已被研究，我們會(huì)將卷取溫度最優(yōu)化來(lái)克服這個(gè)問(wèn)題。

我們對(duì)自己的過(guò)失及其帶來(lái)的不便深感抱歉。如果可能，希望你能接受替代出運(yùn)，如果不行的話，我們會(huì)立即歸還貨款。
