摘    要：为提高中厚板热处理线的装备水平及制造能力,满足高品质、高强度、高韧性钢板的生产需求,通过技术集成,采用脉冲数字化燃烧控制技术、炉后快速冷却装置、常化炉仪控及电控系统和计算机在线优化控制,自主开发了常化炉自动化控制系统及NCC控冷技术,形成了一套完整的中厚板常化+控冷生产工艺。该项技术完全达到中厚板热处理线的要求,炉温控制精度在±10℃以内,产品合格率达到96%以上。

Abstract: In order to raise the technical level of equipment and manufacturing capacity of continuous heat treatment line in medium plate mill to produce plate of high quality,high strength and toughness,a normalizing furnace automatic control system and NCC controlled cooling technology was developed independently which is an integration of pulse-digital combustion technique,equipment of fast cooling,electric control system of normalizing furnace and computerized on-line optimizing control system.Thus a set of integrated technology of medium plate normalization plus controlled cooling was established.This technology fulfills the requirements of plate heat treatment,and the furnace temperature could be controlled within ±10 ℃,with product percent of pass over 96%.
