Description

一种弧形振动薄带连铸机及薄带连铸连轧生产线 技术领域
本发明属于冶金领域，涉及一种弧形振动薄带连铸机及薄带连铸连轧生产线。
背景技术
目前，钢铁工业正朝着绿色、低碳、节能、环保、低成本方向发展，短流程连铸连轧工艺流程越来越受到钢铁企业的重视。薄带连铸作为一种近终形的连续铸钢技术，可以直接浇铸厚度15mm以下的薄带连铸坯，然后直接轧制成带材。薄带连铸相对于传统连铸技术，薄带连铸具有工艺流程短、能耗低、投资少、占地面积小、劳动效率高、生产成本低等显著优点，一旦薄带连铸技术方案和关键技术取得突破，将对钢铁工业带来非常重要的影响。
双辊薄带连铸技术1856年由Henry Bessemer提出，二十世纪五十年代开始进行试验并逐步进入工业化生产。双辊薄带连铸采用连铸辊作为结晶器，双辊同步反向高速旋转，钢水在结晶辊中冷却并进行铸轧形成薄带钢连铸坯。由于结晶辊始终沿同一方向旋转，坯壳与结晶辊之间贴合紧密，与常规连铸工艺相比，薄带连铸坯与结晶辊之间缺少润滑和脱模，容易产生粘接，影响薄带钢连铸坯的质量和生产的稳定性。在钢水凝固特殊的工况条件下，由于双辊薄带连铸技术自身存在一定的工艺局限性，并受到一些关键技术的制约，双辊薄带连铸技术至今仍未在钢铁工业中实现大规模工业化生产。
发明内容
有鉴于此，本发明的目的在于提供一种弧形振动薄带连铸机及薄带连铸连轧生产线，以解决当前薄带连铸技术中存在的薄带连铸坯与结晶辊之间缺少润滑和脱模，容易产生粘接，影响薄带连铸坯的质量和生产的稳定性的问题。

弧形振动结晶器1包括内弧振动单元和外弧振动单元，内弧振动单元和外弧振动单元呈对称布置，每个振动单元由弧形铜板1-1、弧形支撑框架1-2、振动驱动装置1-3、支撑轴1-4和支撑底座1-5组成。弧形铜板1-1固定在弧形支撑框架1-2上，弧形支撑框架1-2通过支撑轴1-4支撑在支撑底座1-5上，在振动驱动装置1-3的驱动下，弧形支撑框架1-2及其相连的弧形铜板1-1沿支撑轴1-4作弧形振动。
内弧振动单元和外弧振动单元之间的腔体用于盛接钢水，腔体的上端为钢水入口，下端为薄带连铸坯出口，腔体从钢水入口到薄带连铸坯出口逐渐收窄。
本实施例中，弧形铜板1-1和与其固定的弧形支撑框架1-2的弧形面呈大于四分之一圆的结构，保证弧形铜板1-1作弧形振动时，弧形面始终与刚生成的薄带连铸坯接触，该圆以支撑轴1-4的轴心为圆心。
内弧振动单元和外弧振动单元的弧形支撑框架1-2上分别设有冷却水进水通道和回水通道，弧形铜板1-1内弧面加工有水槽，弧形铜板1-1在弧形支撑框架1-2上固定后，弧形支撑框架1-2上的冷却水进水通道和回水通道与弧形铜板1-1的水槽连通，并与外部冷却水管道相连，形成闭环冷却水通道，对弧形铜板1-1进行冷却。
钢水注入内弧振动单元和外弧振动单元形成的腔体中，通过冷却水通道中的冷却水对弧形铜板1-1进行冷却，在振动驱动装置1-3的驱动下，内弧振动单元和外弧振动单元的弧形铜板1-1随弧形支撑框架1-2分别作独立的弧形往复振动，并且两个弧形铜板1-1及其相连的弧形支撑框架1-2同步振动，形成薄带连铸坯。振动驱动装置1-3可以采用伺服液压缸，也可以采用电机和偏向轴等机构实现驱动。内弧振动单元和外弧振动单元按照一定的振动波形(正弦波或非正弦波)进行振动，弧形铜板1-1的振幅为±1～±20mm，频率为1～10赫兹，具体可以根据薄带连铸坯的拉坯速度进行相应设定和调节。两个振动单元同步向下作弧形振动时，具有铸轧的功效，有利于薄带钢连铸坯的生成；同步向上作弧形振动时，有利于薄带连铸坯与弧形铜板1-1之间脱模和润滑剂的加入，防止粘接，提升表面质量。
外弧振动单元的支撑底座1-5固定；内弧振动单元的支撑底座1-5通过丝杠调节机构能够相对于外弧振动单元的支撑底座1-5水平移动，并通过锁紧装置1-6进行锁紧，用于调节 内弧振动单元和外弧振动单元之间的间隙，实现生产不同厚度的薄带连铸坯。
压下驱动装置2布置在弧形振动结晶器1的下方，紧靠弧形振动结晶器1。压下驱动装置2由内弧驱动辊和外弧驱动辊组成，分别通过相连的电机、减速器、万向联轴器驱动进行相对转动，内弧驱动辊通过液压缸驱动可向外弧驱动辊水平移动，对薄带连铸坯进行夹紧和驱动。在弧形振动结晶器1中生成的高温薄带连铸坯立即进入压下驱动装置2，压下驱动装置2内弧驱动辊在液压缸的驱动下可以对薄带连铸坯进行一定量的压缩，有利于改善薄带连铸坯的内部组织，提升薄带连铸坯的内部质量。
薄带连铸坯导向装置3由一对或多对自由辊组成，可以根据实际需要设置自由辊的数量，自由辊沿薄带连铸坯弧形走向进行布置，对薄带连铸坯进行支撑和导向。
如图2所示，本实施例还提供一种薄带连铸连轧生产线，包括沿生产流线依次布置的弧形振动结晶器1、压下驱动装置2和薄带连铸坯导向装置3、薄带驱动辊4、轧机5、薄带冷却装置6、剪切机7和卷取机8。弧形振动薄带连铸机生产的薄带连铸坯通过后续工艺进行轧制、冷却、剪切，然后通过卷取机(8)收集成卷。
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。
