背景技术 Background

[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] slab continuous casting process, the slab will generally exist center segregation and center porosity and other defects, affected by the composition and properties of the strand solidification, the center segregation and center porosity defects Carbon Equivalent steel billet more serious, dynamic pressure technology to control the slab density and homogeneity, which play to enhance the quality of blooms, improve production efficiency purposes casting online depressed solidification shrinkage compensation slab center. 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。 Through online tracking strand solidification process, the timely implementation of reduction in place or dynamically adjust the roll gap is called dynamic pressure. 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, as users of the slab quality requirements continue to increase, 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 the dynamic pressure of the billet caster casting machine due to small radius, small strand section can be used for short length of the dynamic pressure of the liquid zone, more pressure rollers must be arranged within a limited range of pressed and deform the slab; to achieve dynamic pressure, must be timely implement dynamic adjustment of the roll gap pressure or in a suitable position according to the tracking results, so each must be controlled separately on the roll; because the slab to deformed, in order to improve quality of blooms, each center on a roll and the lower roll connection must be arranged in the normal line straightening the curve, that is the vertical centerline of the vertical centerline of the hydraulic cylinder and rack slide coincide with the curved slab are normal, and can adapt to different strand section.
