摘要
随着喷煤PLC控制系统的投入使用，结束了原本相对落后的喷煤操作控制技术，安全高效的生产，最大限度地满足了高炉喷煤，取得了显著的成效，为铁厂节能降耗发挥了积极的作用。
With PLC control system being used for coal injection, the old coal injection operation control technology was improved, coal injection rate did then meet the need of BF, significant results was achieved, and to play a positive role for energy conservation and consumption reduction iron works.
