前言铁合金电炉是耗能很大的设备,铁合金生产是一个很复杂的高温物理化学过程,原料的称量控制,又是铁合金电炉生产中的关键问题,它直接影响着炉子的正常运行和技术经济指标。目前国内基本上是采用电子秤和单元仪表组合的称量系统,由于没有称量的补偿功 Preface Ferroalloy furnace is energy-intensive equipment, ferroalloy production is a very complex high-temperature physical and chemical processes, raw material weighing control, but also the production of ferroalloy furnace key issues that directly affect the normal operation of the furnace and technical and economic index. At present, the basic is the use of electronic scales and unit combination meter weighing system, because there is no weighing compensation work
