自动化与冶金工业发展关系极大,它影响产品质量、产量和收得率。特别是近代钢铁工业,由于大型化、高速化,稍一出现不正常就损失很大,而且人工控制是很难达到高产、优质、高效和低耗的。自动化对提高冶金工业的效益是非常显著的。例如大型加热炉使用了燃烧等控制以后,可节省煤气10～15%并减少了氧化铁皮烧损,年经济效益超过50万元;大型铁合金电炉(16500千伏安),在上料、电极压放和功率控制上实现自动化以后,其节电、增产而获得的经济效益每年超过100万元以上。
Automation has a great relationship with the development of the metallurgical industry, which affects product quality, yield, and yield. In particular, the modern steel industry, due to its large size and high speed, suffered a great deal of damage when it appeared abnormally, and manual control was difficult to achieve high output, high quality, high efficiency, and low consumption. Automation is very significant for improving the benefits of the metallurgical industry. For example, large-scale furnaces use combustion and other controls, which can save 10-15% of gas and reduce the burning of iron oxide skin. The annual economic benefits exceed 500,000 yuan; large-scale ferroalloy electric furnace (16500 kVA), on the feeding, electrode pressure After the automation of power generation and power control is achieved, the economic benefits obtained from power saving and production increase are more than 1 million yuan per year.
