高炉炼铁过程十分复杂,它涉及到气、液、固三态的交互作用,因此,利用人工操作很难实现精确控制。并且高炉在整个钢铁生产中处于重要地位,它直接关系到钢铁的产量与质量。因此,随着PLC和网络技术的飞速发展,对高炉控 Blast furnace ironmaking process is very complicated, it involves the gas, liquid, solid three-state interaction, therefore, the use of manual operation is difficult to achieve precise control. And the blast furnace in the entire steel production is in an important position, it is directly related to the production and quality of steel. Therefore, with the rapid development of PLC and network technology, blast furnace control
