炼钢－连铸－热轧作为钢铁生产流程中的三大关键工序，它们之间不仅存在物流平衡和资源平衡问题，而且存在能量平衡和时间平衡问题。为了节省能源、减少烧损、缩短生产周期，国外钢铁企业十分关注它们的一体化管理。结合我国具体情况，对炼钢－连铸－热轧一体化管理的内容、意义、条件以及国外情况进行了系统的阐述。 Steelmaking - Continuous Casting - Hot Rolling As the three key processes in the steel production process, there are not only logistics balance and resource balance among them, but also energy balance and time balance. In order to save energy, reduce burning, shorten the production cycle, foreign steel companies are very concerned about their integrated management. According to the specific conditions in our country, the content, meaning, conditions and overseas situation of integrated management of steelmaking, continuous casting and hot rolling are systematically expounded.
