PAGE\*MERGEFORMATVI提供全套毕业论文，各专业都有设计两座300t高效转炉炼钢车间摘要本文主要介绍了300吨高效顶底复吹吹转炉及炼钢车间设计。炼钢过程就是铁水向钢水转变的过程，这对加入料及产物的成分、数量都有严格要求。本设计简要介绍了我国炼钢技术的发展历程。然后从物料平衡和热平衡方面进行计算，以100千克单位铁水量为基础进行计算确定了合理的原料成分及原料加入量，以确保物质和能量的守恒；再依给定的300吨氧顶底复吹转炉设计出其炉型及相应的氧腔及水冷装置等。然后对连铸的生产能力进行计算，采用三炉连浇、一机二流的三台连铸机进行同时生产，使连铸生产能力达到了预计的产量要求，确定炼钢厂的布置，最后简单设计烟气净化系统及精炼设备，最终完成设计。关键词：物料平衡和热平衡,氧气顶底复吹转炉,氧枪,炼钢车间,精炼设备AbstractThispaperintroduces300-tonefficientavoidancesthecombined-blowingconverterandsteel-makingplantdesign.Steel-makingprocessistheprocessoftransformationofhotmetaltothemoltensteel,whichmaterialsandproductsbyaddingingredients,quantity,therearestringentrequirements.Thedesignbrieflydescribesthehistoryofsteelmakingtechnology.Andfromthematerialbalanceandheatbalancecalculationto100kgunitsofironwater,calculatedonthebasistodetermineareasonablerawmaterialcomponentsandrawmaterialsbyaddingvolumetoensurethatmaterialsandenergyconservation;thenfollowthegiven300tonsofBOFandthecorrespondingdesignofthefurnacechamberandthewaterofoxygendevices.Thencalculatedtheproductioncapacityofcontinuouscasting,continuouscastingfurnacewiththree,threesecond-rateonemachinesimultaneouslycastingmachineproduction,theproductioncapacityofcontinuouscastingproductionreachedtheexpectedrequirements,determinethelayoutofsteelmills,andfinallysimplefluegaspurificationsystemdesignandrefiningequipment,completethedesignrequirements.Keywords:materialbalanceandheatbalance,BOF,oxygenlance,steelmakingworkshop,refiningequipment.目录TOC\h\z\t"样式1,1,样式2,2,样式3,3,样式4,4"HYPERLINK\l"_Toc390092739"摘要PAGEREF_Toc390092739\hIHYPERLINK\l"_Toc390092740"AbstractPAGEREF_Toc390092740\hIIHYPERLINK\l"_Toc390092741"第1章绪论PAGEREF_Toc390092741\h1HYPERLINK\l"_Toc390092742"1.1中国炼钢生产技术的发展PAGEREF_Toc390092742\h1HYPERLINK\l"_Toc390092743"1.2转炉高效吹炼工艺技术PAGEREF_Toc390092743\h1HYPERLINK\l"_Toc390092744"1.3转炉顶底复合吹炼工艺PAGEREF_Toc390092744\h2HYPERLINK\l"_Toc390092745"1.4煤气回收与负能炼钢PAGEREF_Toc390092745\h2
