Continuous Casting and Rolling of Steelmaking and Rolling Interface in Heavy Steel New Area

On May 16th, under the organization of the production and command center in the New Steel Development Zone, the steelmaking production line and the two steel rolling production lines operated cooperatively, and two continuous casting machines successfully delivered slabs to the 1780mm hot-rolled sheet line at the same time. On the same day, No. 3 continuous casting machine also successfully connected with the 4100mm wide-thick plate production line. As a result, continuous steel casting and continuous rolling were realized at the interface between steelmaking and rolling steel in the new steel area.

On the following 18th, from 9..45 to 20..00, No. 1 caster and No. 2 caster in the continuous casting operation area of ​​the steelmaking production line respectively sent cumulative heat to the 1780mm hot rolled sheet line and the 4100mm wide plate line. 22 furnace quality steel billets, since then, the steelmaking and rolling steel interface in the new steel area has started continuous casting, continuous rolling one-stop assembly line operations, which will reduce logistics costs, energy costs, process costs, improve product quality will play a positive Promote the role of a landmark.

It is understood that the continuous relocation of heavy steel No. 3 and No. 2 casters were put into operation in December 2009 and September 2010, respectively. In contrast, the No. 1 slab caster in the Chongqin New District has recently been replaced with an online rapid replacement package. This success marks the significant progress made in the continuous casting system of the New Steel District in grasping new equipment, new processes, and new technologies, laying the foundation for improving the operating rate of the caster and accelerating the production rhythm.
