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 .
