高炉喷煤生产中,由于工艺的特殊性,按常规方法电子秤无法工作。为此采取了特殊措施:采用自动切换方法以连续测量加料过程中的喷煤量,采用压力补偿方法以消除浮力影响,釆用喷煤罐电子秤传感器吊挂在贮煤罐上的特殊安装方式以防止贮煤罐被浮起。实际经验还表明,为消除电气干扰须接地和并联电容器。
Blast furnace coal injection production, due to the special nature of the process, according to the conventional method of electronic scales can not work. To this end has taken special measures: the use of automatic switching method to continuously measure the amount of coal injected during the feeding process, the use of pressure compensation method to eliminate the impact of buoyancy, preclude the use of coal injection tank electronic scale sensor hanging in the coal storage tank on the special installation To prevent the coal storage tank from being floated. Practical experience also shows that in order to eliminate electrical interference, grounding and shunt capacitors are required.
