大方坯结晶器振动系统测试及分析

Test and Analyze on Mould Oscillation System of Billet Caster

针对北满特钢大方坯连铸机振动平台和结晶器振动系统存在的问题,采用专用的测量设备对其进行了测试,发现连铸机振动平台发生了弯曲,结晶振动系统存在侧向和弧向的偏振,主振动的振幅也和设定值有偏离,说明振动系统存在严重变形和磨损,振动系统的稳定性和精度已经不能满足连铸工艺要求,必须进行大修。

In this article a special designed measuring equipment has been applied to test stroke and wave shape of oscillator in Beiman special steel billet caster.The test found that the mould osallation platform was bended,mould osallation system was polarized in directions of side and arc,and amplitude of main vibration was leant to the set value.This showed that serious wear and tear existed in the oscillation system.The oscillation system must be overhauled to secure the stability and accuracy of mould oscillation.
