目前,发达国家和地区已广泛采用立式连铸工艺生产高合金钢,并开发了大量新工艺技术。
国内立式连铸生产工艺尚不成熟,还处于摸索阶段,生产的铸坯裂纹缺陷严重,产品合格率较低。
铸坯中产生裂纹的原因非常复杂,受工艺参数、组织、设备等诸多因素的影响,其中由于不合理的连铸工艺所形成的热应力是铸坯热裂加剧的主要原因[1]。
因此在连铸生产中,为提高铸坯质量,应尽量避免铸坯中热裂纹的产生,充分了解铸坯在凝固过程中的热应力变化规律,从而选择合理的连铸工艺参数,从根本上避免热裂纹的产生。
目前,研究者对连铸坯热应力变化做了大量模拟研究,并取得了很多有意义的结论[2- 7]。
但以往的计算模型多为长度方向二维模型或截面三维切片模型,或以简化的短模型来研究铸坯的应力分布,忽略了铸坯横向或纵向应力应变的影响,显然对模型进行了较大的简化。
铸坯在冷却过程中要发生体积膨胀或收缩,但由于铸坯作为一个连续体,其内部横、纵向相互约束,使得铸坯膨胀或收缩变形不能自由进行,从而在铸坯中产生热应力[8]。
若忽略铸坯的横向或纵向应力应变,将引起铸坯内应力状态的改变,使模拟结果与实际情况存在较大的差别。
而短模型虽为三维模型,但只集中于研究结晶器内凝固坯壳及结晶器铜板的应力应变状态,模型较短,不能反映铸坯在整个连铸过程中热应力的分布规律。
结晶器(mould)承接从中间罐注入的钢水并使之按规定断面形状凝固成坚固坯壳的连续铸钢设备。
它是连铸机最关键的部件,其结构、材质和性能参数对铸坯质量和铸机生产能力起着决定性作用。
开浇时引锭杆头部即是结晶器的活动内底,钢水注入结晶器逐渐冷凝成一定厚度坯壳并被连续拉出,此时,结晶器内壁承受着高温钢水的静压力及与坯壳相对运动的摩擦力等产生的机械应力和热应力的综合作用,其工作条件极为恶劣。
为了能获得合格的铸坯,结晶器应满足的基本条件有:(1)具有良好的导热性,以使钢水快速冷凝成形。
(2)有良好的耐磨性,以延长结晶器的寿命,减少维修工作量和更换结晶器的时间,提高连铸机的作业率。
(3)有足够的刚度,特别在激冷激热、温度梯度大的情况下需有小的变形。
(4)结构简单、紧凑,易于制造,拆装方便、调整容易,冷却水路能自行接通、以便于快速更换;自重小,以减小结晶器振动时的惯性力和减少振动装臵的驱动功率,并使结晶器振动平稳。
Can take from the middle of the molten steel into the required section and shape into a solid billet solidification of continuous casting equipment shells. Continuous casting machine which is the most critical components, its structure, texture and performance parameters on the quality and slab caster plays a decisive role in production capacity. When open pouring dummy bar head mold that is at the end of the activities, of molten steel into the mold gradually condensed into a certain thickness and continuous billet shell out, at this time, mold wall temperature under the static pressure of molten steel and billet shell, such as the relative movement of the friction generated by mechanical stress and thermal stress of the combined effects, the extremely bad working conditions. In order to obtain qualified casting, mold should be to meet the basic conditions are: (1) has a good thermal conductivity to enable rapid condensation forming molten steel. (2) good wear resistance to extend the life of mold to reduce the workload of maintenance and replacement of the time mold and improve the operating rate of continuous casting machine. (3) have sufficient rigidity, especially in the cold shock-induced heat, large temperature gradient would be required under a small deformation. (4) structure is simple, compact, easy to manufacture, easy disassembly, easy adjustment, cooling water can be connected to in order to facilitate the rapid replacement; self-small, to reduce vibration at the time of mold and reduce the vibration of the inertial force of the drive power devices and a smooth mold vibration.分类按拉坯方向上断面内壁的线型分结晶器的型式有弧形和直形两种;按其总体结构,不论弧形或直形均有套管式和组合式两种。
薄带连铸熔池波动特性的物理数值模拟研究任三兵;樊俊飞;方园【摘要】薄带连铸生产铸带过程中,熔池波动大小对铸带质量影响较大,而引起波动的主要因素来自浇铸本身的工艺特性及外部设备影响.针对宝钢的薄带连铸机组,按照相似准数建立了1∶1水模型装置,测定了吐出孔位置的液面波动情况.与此同时,采用湍流双方程模型及VOF方程建立了配套水模型的液面波动模型,利用该模型研究了结晶辊静止时,布流器吐出孔位置的熔池液面波动情况.结果表明,不考虑结晶辊转动时,波动主要由吐出孔流出的钢水引起,波动形式比较单一.此外,该研究考虑了铸带拉速、吐出孔浸入深度、吐出孔倾斜角度等因素对熔池液面波动的影响,并将计算模拟结果与水模型结果进行了对比,两者吻合较好.【期刊名称】《宝钢技术》【年(卷),期】2017(000)003【总页数】5页(P9-13)【关键词】薄带连铸;物理模拟;数值模拟;布流器【作者】任三兵;樊俊飞;方园【作者单位】宝山钢铁股份有限公司研究院,上海201900;宝山钢铁股份有限公司研究院,上海201900;宝山钢铁股份有限公司研究院,上海201900【正文语种】中文【中图分类】TF777薄带连铸是一种近终形连续铸钢技术,它可以直接浇铸厚度10 mm以下的薄带坯,可经热轧或冷轧成带材。
探索利用双辊直接浇铸板材的方法可以追溯到19世纪,最早提出这一思想的是贝塞麦(Henry Bessemer)。
1856年,他用双辊顶部浇注工艺成功浇铸了带钢,此后又进行了多种试验方案,由于有色金属熔点低,使得有色金属薄带连铸较早地进入生产阶段。
对于薄带连铸浇铸过程来说,熔池液面波动情况直接影响铸带的表面质量,在某些条件下,当熔池液面波动超过6 mm时,铸带将产生纵裂纹;但是如果熔池液面波动较小时,由于熔池表面散热显著,容易在表面结冷钢膜。
与连铸熔池相比,薄带熔池小得多,另外薄带熔池表面无保护渣覆盖,所以其波动状况比连铸熔池更难控制。
引起薄带熔池液面波动的因素很多,从浇铸工艺的影响来说,包括铸带拉速、吐出孔浸入深度、吐出孔倾斜角度等;从设备方面的影响来说,包括结晶辊的转动、结晶辊表面粗糙度、机架的震动等;从布流器系统本身来说,包括布流器的形式、布流器的变形等。
