固体燃料粒度对烧结过程质量的影响与对策

The Impact of Solid Fuel Particle Size on Sintering Process Quality and Corresponding Countermeasures

摘要

铁矿烧结是钢铁冶炼、冶金生产的核心前置环节，烧结的稳定性和品质对于高炉炼铁的生产效率、能耗水平和成品质量影响较大，而固体燃料作为烧结过程中的核心热源，其粒度对烧结过程和质量的影响也是相对较大的，粒度过大或过小都会对正常生产产生一定冲击，在这样的背景下可通过推行燃料粒度分级精准管控模式、优化燃料破碎筛分设备与工艺、细化烧结全流程粒度管控标准和管理制度保障烧结效果，稳定生产工况，提升烧结矿综合品质，为烧结行业节能提质、标准化生产提供更多帮助。

Abstract

Iron ore sintering is a critical preliminary step in steelmaking and metallurgical production. The stability and quality of sintering significantly impact the production efficiency, energy consumption, and final product quality of blast furnace ironmaking. As the primary heat source during the sintering process, solid fuel particle size exerts considerable influence on both the process and final product quality; particles that are either too large or too small can adversely affect normal operations. In this context, implementing a precise fuel particle size grading control system, optimizing fuel crushing and screening equipment and processes, and establishing detailed particle size control standards and management protocols throughout the entire sintering workflow can ensure optimal sintering performance, stabilize production conditions, enhance the overall quality of sintered products, and contribute substantially to energy conservation, quality improvement, and standardized production practices in the sintering industry.
