摘要
叙述了天铁烧结二级控制系统的组成和基本功能,针对烧结配料成分、混合料加水量波动大,控制精度低及烧结过程大滞后等问题,通过建立数据库、采用时序跟踪预测相结合等方法提高了系统控制精准度,解决了烧结过程连续性和自动控制滞后的矛盾。该系统自投入运行后稳定使用率达到97.9%,烧结各项指标明显提升,降低了能耗和人工成本费,达到了企业提质降耗的目的。
The paper describes the constitution and basic functions of Tiantie Sintering Level 2 control system. Aiming at the problems of big fluctuation of sinter blending composition and water addition for mixing material, low control precision and long lag of sintering process, methods of establishing database and adopting time sequence tracking prediction were taken to improve system control precision and remove contradiction between the continuity and automation control lag of sintering process. The availability of the system after being putting into operation reached 97.9% and all indices of sintering remarkably went up. Energy consumption and labour cost were lowered and the goal that the enterprise improved quality and lowered consumption was hit.
