Description
技术领域
本发明属于金属层状复合板材制备技术领域,具体涉及一种添加不锈钢丝网中间层的不锈钢/碳钢层状复合板及其制备方法。
背景技术
不锈钢/碳钢复合板既具有不锈钢的耐腐蚀性,又具有碳钢良好的力学性能,成本大幅降低,具有良好的经济和社会效益,广泛应用于石油化工、核能发电、远洋船舶等综合性能要求较高的领域。
目前,工业上主要采用爆炸复合法和热轧复合法制备不锈钢/碳钢复合板爆炸复合法利用炸药作为能源,复合界面呈波浪状,界面由强机械结合和冶金结合构成,复合效果较好,但无法制备薄板、难以实现连续生产、板形尺寸精度难以控制且环境污染严重。,热轧复合法轧前需要组坯四周焊接、抽真空密封等工序,在高温条件下热轧复合过程中界面容易发生元素互扩散,导致界面不锈钢侧生成脆性碳化物、碳钢侧形成贫碳区,影响复合板结合强度和力学性能。因此,目前通过在不锈钢和碳钢界面添加合适厚度和成分的纯铁、纯铜、纯镍及其合金等中间层,可以阻碍元素的扩散、防止界面生成金属间化合物,达到提高界面结合性能的效果。但是,在不锈钢和碳钢板中间添加中间层后,仍然需要组坯四周焊接抽真空或者在真空条件下热轧,工艺繁琐,且不能实现连续制备。冷轧复合法可以省却组坯四周焊接、抽真空密封等工序,但由于室温环境下不锈钢表面塑性和自愈性极好的氧化膜难以开裂挤出新鲜金属与碳钢结合,界面难以复合。
因此,针对目前不锈钢/碳钢复合板制备方法存在的能耗大、工艺复杂、成本高、冷轧难以复合等问题,有必要开发一种短流程、高效率的不锈钢/碳钢复合板的新方法。
发明内容
本发明的目的是提供一种添加中间层的不锈钢/碳钢层状复合板及其制备方法,通过表面改性改变不锈钢丝网表面性质,表面成分转变为碳氮化物、超饱和渗碳体等,表面硬度提升超过不锈钢板和碳钢板,促使表面改性不锈钢丝网在与不锈钢板、碳钢板叠合组坯冷轧过程中易于开裂与两侧板材嵌合,同时在界面形成类爆炸复合的三维网状结构,获得较高界面结合强度的不锈钢/碳钢冷轧预复合;然后无需保护气氛或真空条件,进行后续不锈钢/碳钢热轧终复合,在热轧过程中,由于不锈钢丝网表面改性层的存在,可以有效控制碳钢侧碳元素和不锈钢侧铬、钼、锰、镍等元素互扩散,调控界面成分和组织,提高界面性能,最终获得高性能不锈钢/碳钢复合板的高效制备。

进一步地,当所述表面改性处理为渗氮处理时,其处理温度为400~600℃、保温时间为0.1~10h,进一步优选渗氮处理温度450~550℃、保温时间0.5~2h,该温度和时间的选择使得能够保证表面改性不锈钢丝网表面能够开裂,并且嵌入不锈钢板和碳钢板,界面实现有效复合,同时确保不锈钢/碳钢复合界面的耐蚀性不受影响。
进一步地,当所述表面改性处理为氮碳共渗处理时,其处理温度为400~650℃、保温时间为0.1~5h,进一步优选氮碳共渗温度为450~550℃、保温时间0.5~2h,该温度和时间的选择使得能够保证表面改性不锈钢丝网表面能够开裂,并且嵌入不锈钢板和碳钢板,界面实现有效复合,同时确保不锈钢/碳钢复合界面的耐蚀性不受影响。
进一步的,所述表面改性不锈钢网的成分为碳氮化物、超饱和渗碳体及其混合物,表面硬度为不锈钢板的1.5~3倍。

步骤三:将表面打磨的不锈钢丝网(直径0.5mm、孔径1mm2)进行表面碳氮共渗,温度为480℃,保温时间为3.5h;;
步骤四:将碳氮共渗后的不锈钢丝网、表面打磨的不锈钢板和碳钢板按照“不锈钢板/表面改性不锈钢丝网/碳钢板”方式叠合组坯,并进行冷轧,轧制压下率为55%,制备得到预复合的不锈钢/碳钢层状复合板坯;
步骤五:将所得复合板坯送入1050℃热处理炉中保温15min后再次送入轧机中,轧制压下率为10%,制备得到高性能不锈钢/碳钢层状复合板。
实施例4(对比实施例):
以316奥氏体不锈钢板(厚度1㎜)和碳钢板(厚度2㎜)、镍箔(厚度0.1mm)为原材料,传统热轧法添加镍中间层制备不锈钢/碳钢复合板。
步骤一:分别将不锈钢板和碳钢板送入1050℃和880℃热处理炉中保温30min,采用氩气作为保护气进行软化退火;
步骤二:对不锈钢板和碳钢板、镍箔表面进行清洁处理,然后采用金刚石碗磨对不锈钢板和碳钢板表面进行机械打磨;
步骤三:将表面机械打磨的不锈钢板和碳钢板、镍箔进行叠合组坯,对组坯四周进行氩弧焊焊合,一端留小孔,通过预留孔对不锈钢/碳钢组坯采用极限压力0.1Pa的真空泵进行抽真空,达到极限压力后继续抽真空5min,采用圆头锤对抽真空圆管口进行敲击,直至圆管口变扁平,然后关闭真空泵;
步骤四:将焊接抽真空的不锈钢/碳钢组坯送入1200℃热处理炉中保温30min,然后送入轧机,轧制压下率20%;
步骤五:将热轧一道次的不锈钢/碳钢复合板送入1150℃热处理炉中保温10min,然后送入轧机,轧制压下率20%;
步骤六:重复步骤五,经过三道次热轧,总压下量达到50%,得到不锈钢/碳钢层状复合板。
由此,本发明通过表面改性控制不锈钢丝网表面成分和硬度,促使表面改性不锈钢丝网在与不锈钢板、碳钢板叠合组坯冷轧过程中易于开裂与两侧板材嵌合,如图2所示,同时可在界面形成负角度的三维网状金属填充结构,进一步增加界面结合面积,获得较高界面结合强度的不锈钢/碳钢冷轧预复合,后续热轧过程中阻碍元素的扩散、防止界面生成金属间化合物,达到提高界面结合性能的效果。其中,剖面1和2是对应不锈钢丝网的不同位置,剖面1为不锈钢丝网单一丝线位置,剖面2为不锈钢丝网节点位置。本发明可在大气环境下直接进行不锈钢/碳钢轧制复合,简化了生产工艺,缩短了工艺流程。
需要说明的是,以上实施例仅用以说明本发明的技术方案而非限制,尽管参照较佳实施例对本发明进行了详细说明,本领域的普通技术人员应当理解,可以对本发明的技术方案进行修改或者等同替换,而不脱离本发明技术方案的宗旨和范围,其均应涵盖在本发明的权利要求范围当中。
