摘 要
根据设计任务要求，进行年产200万吨宽厚板车间设计。设计要求设备较为强大，能生产多品种多用途优质宽厚板。
设计内容包括建厂经济依据、产品大纲分配、原料选择、总道次选择、轧机比较及选择、压下规程计算、速度计算、温降计算、力能计算、轧辊校核、凸度计算、辅助设备选择等。
高级中厚板具有高强度、高性能，一般力能较小的宽板轧机不能进行生产。为了在新疆建立高档次宽厚板车间，轧制包括管线钢在内的多种优质宽板，特别选择强力变形的中厚板轧机。
设计中尽量采用先进的厚板生产工艺和带辊形调整的轧机，并与许多新技术系统相结合来保证生产高精度宽厚板。选用了德国西门子公司提供的CVC轧机与正负弯辊系统，从而能使设备与工艺水平各方面都居于领先水平。
轧制线采用高水平的控轧控冷工艺，为了减少控轧工艺对产量的影响，采用多块钢交叉轧制工艺及中间喷水冷却，加速冷却装置采用喷射冷却和层流冷却组合形式，在该装置上可实现直接淬火（DQ），具有高冷却速率及冷却速率调节范围广等特点，为投产后拓宽品种创造了条件。

篇二：《热轧H型钢轧钢车间设计》
热轧H型钢轧钢车间设计
(design of hot H-beam mill)
以连铸坯、热轧坯为原料，经加热和万能轧机轧制，生产热轧H型钢产品的车间设计。H型钢过去称为宽边工字钢，属于经济断面型钢。它与工字钢相比，其断面特点是翼缘(腿)可更宽、腹板(腰)可更高，而壁较薄；在相同断面面积时，H型钢的截面抵抗矩、惯性矩等力学性能都比工字钢高，可获得优良的抗弯能力和稳定性；腿部内外侧平行，呈直角，故拼装连接方便；形状美观。H型钢主要用于制作高层民用建筑的构件，工业厂房的梁、柱和桩，桥梁钢结构件，重型车辆桥架及各种机械的构件和机座等。H型钢用在建筑结构上可减轻重量30％～40％，做拼装组合构件可减少焊接、铆接工作量达25％。在工业发达国家，目前热轧H型钢产量约占热轧钢材产量的2％～6％，占型钢产量的30％～60％。
H型钢产品按翼缘宽度分为宽翼缘H型钢(HK)、窄翼缘H型钢(HZ)和H型钢桩(HU)三大类。中国国家标准规定的H型钢产品规格范围见表1。目前国外生产的H型钢断面最大高度达1200mm，最大翼缘宽度达530mm。H型钢的材质，主要有碳素钢和低合金结构钢，少量为含低镍、低铬的低温用钢和海洋用钢。热轧H型钢轧钢车间设计的原则和方法见轧钢厂设计。
简史 1867年德国哈哥?萨克(Huge Sack)发明带立辊的万能轧机，1901年卢森堡阿尔贝德一迪弗当日(Arbed-Differdange)厂建成了由万能机架和轧边机架组成的格雷式(Grey)H型钢轧机，德国和美国等国也相继建成了此类轧机，但在20世纪前半个世纪建成甚少。直至20世纪60年代，由于建筑业的高速发展，市场对H型钢的需求量增加，加快了H型钢轧机的发展，特别是轧钢技术和电控技术的进步，使其向多品种、自动化、中型轧机的连续化方向发展。1985年联邦德国西马克(SMS)公司开发了由两架万能机架和一架二辊轧边机架组成的串列式万能轧机，轧出了H型钢，使串列式万能轧机向经济型方向发展。至80年代末，全世界已建成H型钢轧机70余套。
中国于20世纪70年代开始研究和设计万能轧机，80年代设计建成了第一条国产化中型H型钢生产线，90年代正在建设大型热轧H型钢轧钢车间。
设计规模与产品方案 根据市场对产品的需要、规划要求和供坯建厂条件及可供选择的设备能力，经综合比较后确定。H型钢产品可以在专业化的热轧H型钢轧钢车间生产，也可在其他型钢轧钢车间生产。前者的设计规模和产品方案见表2。后者的设计规模和产品方案见大型轨梁轧钢车间设计和中型轧钢车间设计。
坯料选择 H型钢产品的特点是品种、规格多，因此一套轧机需多种断面形状和尺寸的坯料。20世纪40～50年代，H型钢产品是以钢锭为原料，一火加热成材，或由初轧机供异形坯、矩形坯两火成材。随着连续铸钢技术和型钢轧制技术的发展，目前大型H型钢
产品可全部选用连铸板坯和异形坯为坯料，中型H型钢产品也可全部选用矩形和异形连铸坯。坯料断面尺寸根据产品尺寸、轧制程序和压缩比要求选择。
工艺流程和轧机布置 根据产品交货要求和坯料条件选择工艺流程，各类H型钢的基本生产工艺流程相似(图1)。
H型钢产品多数用万能法轧制(见大型轨梁轧钢车间设计图2)。大型H型钢产品一般是先热锯切后冷却，在冷床上以“工—工”状态放置，腹板间相互有热辐射，腹板冷却慢，翼缘可实现喷雾冷却，因此，其残余应力最小。中型H型钢因受工艺条件及冷床设备结构的限制，钢材在冷床上是以“H—H”状态放置，然后进行长倍尺冷却、长倍尺矫直和冷锯切。特大断面模数的H型钢用压力矫直机矫直，大、中断面模数的H型钢用辊式矫直机矫直。
H型钢轧机有组合式、串列式、连续式和半连续式等几种布置形式。组合式和串列式布置由粗轧机、万能粗轧机组及万能精轧机组组成。连续和半连续式布置由1～4个粗轧机和4～7个万能轧机及相应数量的轧边机组成。大型H型钢轧钢车间优选串列式布置，老车间改造可选组合式布置；中型H型钢轧钢车间视规模不同可选连续式或半连续式布置。

河北理工大学06级成型课程设计 1产品特点和轧制特点
1 产品特点和轧制特点
不同宽度的热带有不同的用途，也需采用不同工艺技术。热带300mm以下是窄带，多用来生产焊管。300~600mm为中窄带，常用来生产五金或焊接结构梁。600~1000mm为中宽带，薄带卷可以冷轧用于家电。这些产品的轧机一般不安装昂贵的液压压下、弯辊、板型控制设备，只能依靠坯料加热温度控制轧制力，调节板型。
1100~1500mm为宽带，最宽为2000mm，它们的轧机都安装液压压下、在线弯辊、板型控制。2000mm超宽热卷多是用于冷轧镀锌汽车板，由于宽带质量优良，国外主张取消中窄带，用超宽带进行纵剪分切，得到不同宽度卷材，提高成材率。
轧辊越窄，板型凸度控制越容易，且市场对于1m以下冷轧板材，如家电板、家具板或汽车辅助板有较大需求，故按照设计任务书要求，设计典型产品为1m板材，生产厚度精度高、板型优良、表面光洁度高的高档次多品种、宽范围多规格热轧带卷。
1250热带轧机适合轧制带宽为600~1000mm左右的板材。本设计要求既可以生产冷轧需要的2.2mm薄卷，也可生产25mm结构用厚带。
连轧生产具有时间短、温降少、占地少、产量高的特点。1926年，自从美国第一台带钢热连轧机投产以来，连轧带钢得到很大的发展。从手动调节到PID设定，从简单计算机控制到计算机系统多层分布式控制，加上液压压下，液压弯辊，CVC辊型控制等新技术的使用，热连轧机的产量、精度、板型质量得到很大提高。热轧带钢生产线主要包括粗轧和精轧。粗轧轧件短，一般为可逆轧制，精轧为6~7架连轧，成为1/2连轧或3/4连轧。目前，粗轧轧机控制能力越来越强，中间坯凸度命中率大大提高，从粗轧就检测凸度和厚度，为精轧提供优质中间坯料，保证精轧稳定轧出符合技术要求的带卷。粗轧采用大压下，可以减少道次，提高中间坯温度。近来坯料厚度也恢复到原来220mm以上，为多品种、高档次产品生产奠定基础。
课程设计是指定原料厚度的压下规程设计，故热连轧压下规程设计任务包括辊缝、轧辊转速、板凸度、轧辊加工凸度、弯辊力和辊型控制量（CVC抽辊量）的现场轧机工作参数确定。

2原料及产品介绍
依据任务要求典型产品所用原料：
原料规格：
板坯厚度：250mm 钢 种：Q195 最大宽度：1050mm 长 度：8.5m
产品规格：
厚 度：2.6mm 板凸度：0~
6
坯料单重：18吨
因为所给坯料宽度较小，并且在粗轧机前部安装有大立辊，所以侧压较为有效，可以少量控制成品宽度。
坯料选用250mm厚需要较多道次，但对保证压缩比，生产优质板材具有重要意义，生产普板时可以降低原料厚度，以减少道次，增加产量。
坯料长度限定8.5m，加热炉内宽度9.2m，有利于设计高温（1350℃）步进炉，以便为今后生产高牌号硅钢、低合金管线钢储留设备能力。
