Description

共立柱一体化小辊间距动态压下拉矫机 Column total integration of small dynamic pressure roll gap straightening machine

技术领域 FIELD

[0001] 本发明涉及共立柱一体化小辊间距动态压下拉矫机,具体为小方坯连铸机带多点动态压下拉矫机,属冶金行业冶金机械技术领域。 [0001] The present invention relates to an integrated total column of small dynamic pressure roll gap straightening machine, particularly with multi-point billet caster dynamic pressure straightening machine, is the metallurgical industry metallurgical machinery art.

背景技术 Background technique

[0002] 铸坯连铸工艺中,铸坯内部一般会存在中心偏析和中心疏松等缺陷,受成分和铸坯凝固特性的影响,高碳当量钢种铸坯的中心偏析和中心疏松缺陷更为严重,动态压下技术通过在线压下补偿铸坯中心的凝固收缩来控制铸坯内部致密度和均质性,从而起到提升铸坯内部质量、提高连铸生产效率的目的。 [0002] The slab continuous casting process, the slab will generally exist inside the center segregation and center porosity and other defects, affected by the composition and properties of solidification of the slab, center segregation and center porosity defects in the steel billet Carbon Equivalent others severe, dynamic techniques to control pressure inside the billet density and homogeneity to serve the purpose to improve the internal quality of the slab, increase the production efficiency of continuous casting line by pressing the billet center of solidification shrinkage compensation. 通过在线跟踪铸坯凝固进程,适时地在合适位置实施压下或动态调整辊缝则称为动态压下。 SOLIDIFICATION online tracking process to make timely depressed in position or dynamically adjusting the nip pressure is called dynamic. 近年来,随着用户对铸坯质量要求的不断提高,具有动态轻压下、重压下功能的拉矫机越来越受到用户的青睐。 In recent years, with the continuous improvement of slab quality requirements of the user, with a dynamic soft reduction, under the weight of the tension leveler function more and more users of all ages.

[0003] 带动态压下的小方坯连铸机因铸机半径小,铸坯断面小,可用于动态压下的液相区长度短,必须在有限的范围内布置较多的压下辊,对铸坯进行压下使其发生形变;要实现动态压下,必须根据跟踪结果适时地在合适位置实施压下或动态调整辊缝,故每个上辊必须能单独控制;因铸坯要发生形变,以改善铸坯内部质量,每一对上辊与下辊的中心连线必须布置在矫直曲线的法线上,亦即液压缸的垂直中心线以及机架滑道的垂直中心线均与弧形铸坯法线重合,且能适应不同铸坯断面。 [0003] with dynamic depressed billet caster casting machine due to a small radius, a small strand section, can be used for the short length of the dynamic pressure of the liquid layer, pressure roll must be arranged in a more limited range , to be pressed and deform the slab; to implement dynamic pressure must be timely implement dynamic adjustment of the nip pressure or in a suitable position according to the tracking result, it must be able to control each of the rollers individually; slab due to deformed, in order to improve the internal quality of the slab, the center of each of the upper rollers and the lower rollers to be arranged on a line connecting the curve straightening process, i.e. the vertical centerline of the vertical centerline of the cylinder and the slide rack They are normal coincident with the arcuate slab, and can adapt to different strand section.

[0004] 现有小方坯拉矫机通常为整体机架的五辊渐进矫直拉矫机(如附图1所示),机架上共有5个辊子,其中只有两个上辊,上辊转臂一端通过转轴铰接在机架支座上,另一端与液压缸铰接,在液压缸驱动下,上辊绕转轴作圆周运动。 [0004] The conventional billet straightening machine usually five progressive straightening roll straightening machine the entire rack (e.g., 1 shown in the drawings), on the rack total of five rollers, wherein only the two upper rollers, the boom roll end by a shaft articulated on the frame support, the other end of the hydraulic cylinder is hinged, in the cylinder drive, a roll in a circular motion around the shaft. 其不足之处在于:⑴对于不同的铸坯断面,上下辊的中心连线不可能均与矫直曲线垂直,不能适用于轻压下工况;⑵转臂结构占用空间大,在有限的矫直区内只能布置一个上辊,在水平段上布置另一个上辊,无法满足多点适时压下的要求; Its shortcomings in that: ⑴ for different strand section, upper and lower rollers are not possible with the line of centers vertical straightening the curve, is not applicable to soft reduction getting off condition; ⑵ boom large space structures, a limited correction straight area is disposed only on a roll, on the other roller disposed in a horizontal section, can not meet the requirements of timely multi depressed;

现有大方坯拉矫机通常为多机架多点连续渐进矫直拉矫机组(如附图2所示),每组拉矫机为独立机架,机架上的下辊为自由辊,上辊可带有液压缸和传动装置,可实现铸坯的压下及拉矫功能。 Bloom prior straightening machine is generally a multi-stand continuous multi-point straightening progressive straightening unit (as shown in Figure 2), each as a separate straightening machine frame, the lower roller is a free roller on the frame, a roll may be provided with a hydraulic cylinder and the transmission can be achieved and reduction of the slab straightening function. 但此种机型的不足之处为:独立机架占用空间较大,各上辊之间辊间距较大,同样不能满足带动态压下的小方坯拉矫机小辊间距的要求。 However, the disadvantage of this model is: independent rack larger space, the roll gap between the rolls is large, can not meet with the same dynamic pressure of the billet roll straightening machine requiring a small pitch.

[0005] 实用新型专利《一种小方坯连铸轻压下拉坯机》(申请号:CN201320290601.1)所述的装置包括6台拉坯单元、一台脱坯单元和两个自由辊,其不足之处是拉坯单元中无脱坯装置;实用新型专利《一种带轻压下功能的连铸坯拉矫机装置》(申请号:CN02289305.9)所述的装置是小直径密排辊固定于同一个框架上,其不足之处是不能实现单独控制每个上辊,上下辊的中心不可能始终在矫直曲线的法线上;新型专利《具有等机架多点连续渐进矫直技术的拉矫机组》(申请号:CN200920030967.9)是每一组矫直棍固定于一个机架中,每两组矫直辊间有2个立柱,其不足之处是立柱占用空间较大,无法满足带动态压下的小方坯拉矫机小辊间距的要求;发明专利《五辊双机架渐进矫直拉矫机》(申请号:CN01112954.9)同样存在无法满足带动态压下的小方坯拉矫机小辊间距的要求问题。 Casting apparatus comprises six units, a unit off billet and the two free rollers, and: [0005] Utility model patent "soft reduction, a small pull-down blank billet casting machine" (CN201320290601.1 Application No.) the downside is that the casting unit blank without removal means; utility model patent "soft reduction function a tape tension leveler apparatus strand" (application number: CN02289305.9) means the density of small diameter discharge rollers fixed on the same frame, its deficiency could not be achieved on the individual control of each roll, the roll is not always vertical center line in the process of straightening curve; new patent "and the like rack having a multi-point, continuous progression straightening art straightening unit "(application number: CN200920030967.9) is fixed to each of a group of straightening roller rack, there are two each of the two uprights between the straightening roll, its shortcomings is the column space large, unable to meet the billet straightening machine with a small roll gap of the dynamic pressure; patented invention "double five roll straightening machine the straightening rack progressive" (application number: CN01112954.9) there are also unable to meet with dynamic pressure billet straightening machine requirements of small roller spacing.
