It’s an important carrier of the relocation of Shougang's adjustment. The construction of Shougang Jingtang is an important strategic decision for the Party Central Committee and the State council, is an national key project “Eleventh Five Year Plan”, the iron and steel joint enterprise with international advanced level in accordance with the concept of design and construction of a recycling economy. Shougang Jingtang Steel is always under the care of the CPC Central Committee and the State Council. The leaders of the party and the state had researched and come up with important instructions when they came for visit. And they put forward the positioning requirements and construction goals: "high starting point, high standard, high demand; first-class products, first-class management, first-class environment, and first-class benefits”. Shougang Jingtang steel design annual production in the first phase is 8.98 million tons of iron, steel 9.7 million tons, 9.13 million tons of rolled steel. On March 12, 2007 Shougang Jingtang started construction. On May 21, 2009, the No. 1 5500m3 blast furnace air ignition iron, subsequently steelmaking, hot rolling, cold rolling went into operation, Shougang Jingtang Steel is well versed in full line engineering implementation. On June 26, 2010, the main project of Shougang fully completed and put into production. Since Shougang Jingtang went into production comprehensively and actively explore the operation of modern large-scale equipment and advanced technology operating rules. The level of production and process control capability to gradually improve; the capacity of different processes and technical and economic index achieved design level in June 2012, and continue to maintain. Currently, Shougang Jingtang Steel in accordance with national requirements of the state has gradually become a “quality plate production base with international advanced level and independent innovation demonstration plant, to become energy conservation and development of recycling economy iconic factory ". 4 Cold Rolled Appliance Steel Sheets Chapter 2 Production Line Introduction 第二章产线简介 2.1 炼钢系统 Steel making system 炼钢系统是一座崭新的低成本、高品质洁净钢生产平台。 Steel making system is a brand new platform for Low cost and high quality clean steel production. 炼钢系统工艺流程图 / Flow Chart illustrating the Steel-making Process 2.2 热轧系统 Hot Rolling System 首钢京唐拥有 1580mm 和 2250mm 两条热轧生产线，采用了热送热装工艺、工艺润滑技术、大侧压定宽机、自动宽度控制、自动厚度控制、板形控制、控轧控冷以及表面质量在线检测系统等技术。 Shougang Jingtang Steel has two Hot Rolling lines, one is 1580mm Hot Rolling line, and the other is 2250mm.
