在第二次世界大战期间,由于战争的需要工业的发展速度和创新水平都能得到很大的提高。宽厚板的发展也是如此,最初由于战舰、航空母舰等武器装备的发展,对于钢板的质量、强度以及厚度等要求越来越高,宽厚板轧机在这期间得到了很大发展。和平年代,应大型桥梁,核电站,大型水坝,油田钻井平台,大型机械等领域的需要,宽厚板得到了更广泛的应用,这也促进了宽厚板行业的迅猛发展。现如今宽厚板轧机已成为是轧钢行业中的主力轧机,其装备水平及拥有量是一个的重要标志。
现阶段用于生产宽厚板的轧机有以下四种:二辊可逆式轧机、三辊劳特式轧机、四辊可逆式轧机和万能式轧机。其中较为先进的是配有液压AGC系统和弯辊装置的四辊可逆式PC轧机。本设计是为了满足当前市场对宽厚板产品的需求而进行的年产量140万吨的宽厚板生产工艺设计,本设计的粗轧机组和精轧机机组均采用现阶段较为先进的轧机。根据各方面的因素的考虑决定粗轧机组采用普通四辊可逆式轧机,精轧机组采用配有液压AGC系统和弯辊装置的四辊可逆式PC轧机。
设计主要产品及其产量:碳素板30万吨,容器板30万吨,船用板20万吨,桥梁板20万吨,低合金高强度板20万吨,建筑板20万吨。其代表规格为:Q235_16×3500×16000mm3的碳素板。生产所用的板坯为150mm、180mm、200mm和300mm厚的连铸坯。本设计共计算了3种产品的压下规程,分别为:20mm低合金高强度板,16mm的碳素板、30mm的建筑板。

Abstract
In the second world war, because of the war need to industrial development speed and innovation level can be greatly development of the thick plate also is so, first ships, aircraft carrier, due to the development of weaponry, for the quality of the steel plate, intensity and thickness of demand is higher and higher, in this period four-high universal mill got great peace, should be large bridge, nuclear power station, large dam, oil drilling platform, large mechanical and other areas of need, generous board got more extensive application, this also promoted the rapid development of industry and thick four-high universal mill has e the main mill is rolling steel industry, the level of equipment and the ownership is a national steel industry development level of important symbol.
At present for the production of the thick plate mill has the following four: two roll reversible rolling mill, three roller mill, always the type four roll reversible rolling mill and universal type rolling the more advanced is equipped with a hydraulic AGC system and bending roll device four roll reversible PC rolling design is to satisfy the current market for the product demand lenient plate of the annual capacity of million tons of thick plate p
