一、前言为了弄清烧结矿冶金物化性能,本文作者在近几年研究工作中着重研究了烧结矿组成结构与低温还原粉化的关系和烧结矿的强化机理,探索了烧结矿在高炉中的演变与其本身矿物组成粘结相状态的密切关系。通常强度高的烧结矿在高炉中不易粉化,但还原性能不好,致使燃料比增加。但在生产实践中,既要求还原性能好,又要求 I. Introduction In order to understand the physical and chemical properties of sinter metallurgy, the author in recent years, research focused on the structure of sinter and cryogenic reduction pulverization of the relationship between the strengthening mechanism and sinter, to explore the sinter in the blast furnace The evolution and its own mineral composition of the bonding phase of the close relationship. Generally, high-strength sinter is not easily pulverized in the blast furnace, but the reduction performance is not good, resulting in an increase in the fuel ratio. However, in production practice, both the reduction performance requirements, but also required
