摘　　要：介绍了宣钢二钢轧厂小方坯连铸机振动装置的设备组成、性能以及存在的问题。分析了振幅、振动频率、负滑脱时间等振动参数对铸坯表面质量的影响。结合宣钢小方坯生产实践,从振幅选择、振频与拉速匹配关系方面,优化了小方坯的振动工艺参数设置,对同行业小方坯振动优化具有借鉴意义。同时指出,机械振动已经不能满足钢种多样化的需求,新的振动技术必将得到更快速的发展。It is introduced the equipment composition,performance and existing problems of vibration device of billet caster,analyzed the influence of vibration parameters such as amplitude,frequency,negative slip time on surface quality of casting blank. Based on the production practice,the vibration parameters of billet caster is optimized in vibration amplitude selection,matching relation between vibration frequency and casting speed. At the same time it is pointed out that the mechanical vibration has not been able to meet the demand from multi steel grades,and one new technique must be got faster developed.
