由于高炉炼铁的生产规模不断扩大,生铁的需求量也也越来越多,因此对燃料的需求量也日益增加。由于冶金焦炭的供应日趋紧张,高炉喷吹燃料技术得到了很快的发展。其中喷煤就是一项重要的技术革命。喷煤自动控制可以实时对喷吹进行控制和调节,通过PID调节对喷吹量的精确控制,从而实现了无人值守,自动喷吹。通过调节P、I、D的各项数值的设定,使闭环调节能快速调节喷煤量趋于设定值,抗干扰没能力强。
As the scale of production of blast furnace iron and steel, pig iron demand is also more and more, so the demand for fuel is also increasing. Due to the increasingly tight supply of metallurgical coke, blast furnace fuel injection technology has been rapid development. Coal injection is an important technological revolution. Automatic control of coal injection can be real-time injection control and regulation, through the PID regulator on the precise control of injection volume, in order to achieve unmanned, automatic injection. By adjusting the P, I, D of the value of the set, closed-loop adjustment can quickly adjust the amount of coal injection tends to set the value of anti-interference ability.
