[vc_row][vc_column][vc_column_text]On October 31, a factory made a new breakthrough in the industrial test of high-speed steel billet continuous casting. The maximum pulling speed of HRB400 steel with 155*155cm cross-section exceeded 5.7 m/min, breaking the 5.07 m/min set by the plant last year. Minute ultra-high speed record, once again set the highest record of domestic billet continuous casting machine speed!
High-speed continuous casting technology is an advanced technology and development direction in the field of continuous casting. For a long time, Yangchunxin Steel has regarded continuous casting speed increase as the “main battlefield” for efficiency improvement. Through a series of independent innovations, in July 2019, it achieved a billet continuous casting technology of 5.07 m/min ultra-high speed. Subsequently, the company continued to carry forward the spirit of “pursuing the ultimate”, and the steel plant technicians made persistent efforts to complete various project transformations and optimizations in 15 months, including the upgrade of the intelligent control system for steelmaking production, the study of low superheat casting, and the transformation of the tension leveler , Vibration system transformation, high-speed mold flux research, additional cooling section, etc. Through strict equipment precision control to ensure the low wear and long life of the mold, the maximum steel throughput of ordinary single chrome-plated copper pipes can reach more than 18,000 tons, and the maximum continuous casting speed exceeds 5.7 m/min, which is the domestic high speed. Billet continuous casting technology is leading the ranks.
