动态铁水轨道衡的改造

Reformation of Dynamic Railroad Track Scale for Molten Iron Calculation

针对动态铁水专用轨道衡使用过程中存在的台面震动、计量误差大等问题 ,从机械、电器、软件等方面对系统进行改进。通过加固道床、增加台面有效计量长度 ,减少了车列对台面的冲击 ;更换传感器消除了昼夜温差带来的计量误差 ;系统软件增加温漂修正功能和零漂自动补偿功能 ,使系统的综合计量误差率由 2 %降为 0 .3 4%。

Pointing to some problems included big vibration of table surface and big measurement error, etc, in the application process of dynamic special railroad track scale for molten iron calculation the reformation has been made from some ways of machinery, electric device and software. The comprehensive error ratio of the system has been decreased form 2% to 0.34% by means of lengthening the length of table surface, exchanging the sensor to elimination the measurement error between day and night, etc.
