卡拉干达钢铁公司第二烧结厂,自1978年开始逐步实现了一整套旨在完善烧结料加石灰、改进烧结矿饼和返回料(铺底料与反矿)的处理,采取了改善烧结料组成及完善烧结带气体动力学特性的组织措施和技术措施,至使料层厚度从250毫米提高到400～450毫米,烧结矿的产量并未降低。从前认为,在烧结料层厚度250～300毫米的条件下,当烧结矿中氧化亚铁含量为15～17％时,生产能力很高,烧结矿的强度性能好。据此,制定了烧结矿的技术条件。在技术条件中规定氧化亚铁含量应大于15％。这是生产优质烧结矿的一个指标。在改为厚料层烧结时,为了满足技术条件的要求,并生产出含17～18％FeO、2～
Karaganda Iron and Steel Company Second Sintering Plant, since 1978 and gradually realized a set of aims to improve the sinter plus lime, sinter cake and improve the return material (bedding and anti-mine) treatment, taken to improve the sintering material composition And the organization and technical measures to improve the gas dynamic characteristics of the sinter zone have been adopted so that the thickness of the material layer is increased from 250 mm to 400 to 450 mm and the yield of sinter is not reduced. Formerly, when the sintering material layer thickness of 250 to 300 mm under the conditions, when the sinter of ferrous oxide content of 15 to 17%, the production capacity is high, the strength of sinter performance. Accordingly, developed the technical conditions of sinter. In the technical conditions of the provisions of ferrous oxide content should be greater than 15%. This is an indicator of producing high-quality sinter. In the thick layer sintering, in order to meet the technical requirements, and produce a 17 ~ 18% FeO, 2 ~
