唐钢新区的建成投产，是唐钢实现从城市向沿海转移、从内陆发展迈向深蓝布局的历史性转型。作为新区铁前流程的核心龙头装备之一，新建的500m²大型烧结机未沿用传统单点技改模式，而是采用了成套化、体系化、耦合式的先进工艺技术，集成应用了全机高效密封、超厚料层稳产、高比例烟气内循环、环冷余热近零排放、智能精准加水、燃料分级预筛分等一系列行业先进技术。通过这些技术的深度融合与系统协同，从源头上解决了传统烧结漏风率高、能耗高、余热利用率低、工况波动大等行业共性痛点，实现了烧结工序在高效稳产、提质降本、减污降碳、智能稳控等方面的综合提升。

The completion and commissioning of Tangsteel New District represents a historic transformation of Tangsteel. The enterprise has realized its relocation from the urban area to the coastal zone and shifted its development layout from inland regions to coastal bases. As one of the core key facilities in the pre ironmaking process of the new district, the newly constructed 500 m² large sintering machine abandons the conventional single item technical renovation mode. A complete set of systematic and coupled advanced processes and technologies are adopted. Multiple state of the art technologies are integrated. These technologies include full machine high efficiency sealing, stable production under ultra thick bed, high ratio internal flue gas circulation, near zero emission of annular cooler waste heat, intelligent precise water addition and staged pre screening of fuel. In depth integration and systematic coordination of these technologies address typical industry bottlenecks at the source. The existing problems contain high air leakage rate, excessive energy consumption, low waste heat utilization efficiency and severe working condition fluctuation in conventional sintering systems. Comprehensive performance improvements are achieved for the sintering process. The improvements cover stable and high efficiency operation, quality promotion and cost cutting, pollutant abatement and carbon mitigation, as well as intelligent process regulation.
