On March 13th, the R & D project of “regular & dual-regenerative combined-type heating technology and its application in large-sized slab RHF” passed the outcome verification organized by Chongqing Science & Technology Committee. Those experts spoken highly of this technology and thought that the application of it in first advanced large-sized slab RHF realized efficient and reliable utilization of low heating value fuel in high-quality hot strip mill with technology taking the lead in the world.
This combined-type heating tech. has been successfully applied in 1780mm HSM of Chengde Steel. For now, this system is running steadily with all technical indicators exceeding expectation, meanwhile, solving the problem of deficiency of high-heating-value gas and low utilization ratio of low-heating-value gas in steel plants.
