2023年第1期加拿大Tacora精矿烧结工业试验研究吴云,周云花,汤勇,侯盼盼(湘潭钢铁集团有限公司,湖南湘潭411101)摘要:通过加拿大Tacora精矿在烧结工艺的试用,探讨出不同比例加拿大Tacora精矿配比对烧结生产过程技术经济指标的影响规律。工业试验结果表明:加拿大Tacora精矿铁品位高、硅低、铝低,有利于提高烧结矿铁品位和降低烧结矿铝含量;随着加拿大Tacora精矿配比提高,烧结矿中锰含量也相应提高,烧结矿还原性和烧结矿软融性能得到改善;同时加拿大Tacora精矿配比提高,对烧结矿低温粉化影响较小。加拿大Tacora精矿无成球性,配比上升后会影响制粒效果,综合工业试验结果,加拿大Tacora精矿配用比例可控制在15%以内。关键词:加拿大Tacora精矿;烧结;冶金性能中图分类号:TF046.4文献标识码:A文章编号:2095-5014(2023)01-0029-05IndustrialTestofCanadianTacoraConcentrateSinteringWUYun,ZHOUYunhua,TANGYong,HOUPanpan(XiangtanIronandSteelGroupCo.,Ltd.,Xiangtan411101,China)ABSTRACT:Inthispaper,throughtheexperimentofCanadianTacoraironoreconcentratesinthesinteringprocess,theinfluenceofdifferentproportionofTacoraconcentrateonthetechnicalandeconomicindicatorsofthesinteringproductionprocessisdiscussed.TheindustrialtestresultsshowthatCanadianTacoraironoreconcentrateishighinironcontent,lowinsiliconandaluminumcontentwhichisconductivetoincreaseironcontentanddecreasesiliconandaluminumcontentinsinter,andwiththeincreaseofTacoraconcentrateratio,themanganesecontentinsinteralsoincreases,andthesinterreducibilityandthesintersofteningandthawingpropertiesareimproved;meanwhile,theincreaseofTacoraconcentrateratiohaslittleeffectonlow-temperaturepulverizationofsinter.CanadaTacoraconcentrateisbadforpelletizing,andthepelletizingeffectwillbeaffectedaftertheproportionisincreased.Basedonthecomprehensiveindustrialtestresults,itisrecommendedthattheamountofTacoraconcentrateusedinsinteringproductionshouldnotexceed15%.KEYWORDS:CanadianTacoraironoreconcentrates;sintering;metallurgicalproperty收稿时间:2022-10-02第一作者简介:吴云(1987—),男,湖南湘潭,工程师,学士,从事烧结球团工艺研究。金属材料与冶金工程MetalMaterialsAndM...
