中板生产线轧后先进冷却系统的研发及应用

RESEARCH AND APPLICATION OF ADVANCED COOLING SYSTEM FOR PLATE MILL IN NISCO 2800mm PLATE PRODUCTION LINE

为满足高品质节约型中厚板产品的生产需求，降低生产成本，提高产品效益，提升企业竞争力，2012年东北大学轧制技术及连轧自动化国家重点实验室（the State Key Laboratory of Rolling and Automation, RAL）为南钢2800mm中板生产线新建一套具备常规加速冷却（Accelerated Cooling，ACC）功能、超快速冷却（Ultra—fastCooling，UFC）功能、直接淬火（DirectQuenching，DQ）功能的多功能轧后先进冷却装置（Advanced Cooling System for Plate Mill，ADCOS-PM）以及与之相配套的水处理系统和预矫直系统。在此基础上，以新一代控制轧制控制冷却技术（New Generation Thermo—Mechanical Control Process，NG—TMCP）为指导，充分发挥ADCOS—PM系统的技术装备优势，使低成本高强低合金钢、高强工程机械用钢、管线钢以及低温容器钢等一系列高品质节约型中厚板产品得到开发和应用。

To meet the requirements of high performance steel plates, while reducing manufacturing costs and saving energy, the advanced cooling system for plate mill （ADCOS-PM） with functions of accelerated cooling （ACC）, ultrafast cooling （UFC）, and direct quenching （DQ） was researched and developed by the State Key Laboratory of Rolling and Automation（RAL）. In 2012, a new set of ADCOS-PM equipment with auxiliary water treatment facility and preleveler equipment were built in NISCO 2 800 mm plate production line. To fully utilize the ADCOS-PM technology, the combination of various strengthening mechanisms was promoted by NG-TMCP technology and low-cost, high performance plates were produced such as pipeline steels, and high-strength construction machinery steel.
