Abstract
本发明公开了一种薄规格工业纯钛板的生产方法,其包括:(1)将钛材坯体加热,除鳞;(2)将除鳞后钛材坯体进行至少一次粗轧得到钛板坯体;(3)将所述钛板坯体采用热轧机进行至少一次精轧,得到钛板;(4)将所述钛板层流冷却、空冷后得到薄规格工业纯钛板成品;其中,步骤(3)中,通过润滑系统在所述热轧机工作辊上喷涂润滑液。采用本发明的生产方法,能够在高温钛板与轧辊之间形成了一层稳定的轧制油膜,大大降低了钛板与轧辊之间的摩擦力,使得钛板表面质量好,轧制过程稳定,板型平直,厚度控制精度高。

本发明涉及钛板生产领域,尤其涉及一种薄规格工业纯钛板的生产方法。
背景技术
随着科学技术水平的发展,尖端科学技术对金属材料提出了越来越高的要求。例如航空和宇航,核反应堆对金属材料的要求特别严格,这就要求研制耐高温、耐腐蚀、耐磨损、高强度、耐疲劳而重量又轻的金属材料。钛和钛合金与其它结构金属相比具有比强度高、耐腐蚀性强、高低温性能良好及较高的疲劳抗力等显著优点,已经广泛应用于航空航天、化工、造船、海洋、汽车、兵器、建筑等工业领域,而且应用的范围和规模正在逐步扩大。
钛在地壳中储量非常丰富,在常用金属中仅次于铝、铁和镁,自从20世纪40年代首次在真空炉中用镁还原四氯化钛得到海绵钛以来,这种材料便迅速在工业上得到应用。2017年我国消费钛材约8.7万吨,其中钛板占比55份。约4.8万吨,其规格从厚度规格从0.3~70mm,宽度达到2500mm,钛板生产规格多,批量小。建设专门的钛板轧机进行热轧,冷轧建设成本高,生产成本高,因此利用现有的热连轧轧机设备,通过技术开发进行钛板轧制,可充分释放热连轧的设备产能,又可降低钛板的轧制生产成本,可以实现双赢的目的。
钛与其他金属比较,Ti与Fe界面粘着能大于各金属内部结合能,因此当Fe、Ti表面紧密接触并发生相对运动时,断裂将发生于Ti基体较深层处,钛及其合金塑性变形以及机械加工时容易发生粘着现象。因此,采用现有的热轧设备生产钛板时,容易发生粘辊现象,降低钛板的表面质量,同时降低板材的平直度,加工精度等,采用在700~900℃具有良好的专用钛板热轧润滑油,可以得到具有良好的表面质量和好的板形热轧钛带,更好的满足客户需求。

附图说明
图1是本发明一种薄规格工业纯钛板的生产方法的流程图;
具体实施方式
为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述。仅此声明,本发明在文中出现或即将出现的上、下、左、右、前、后、内、外等方位用词,仅以本发明的附图为基准,其并不是对本发明的具体限定。
在现有技术中,钛板轧制过程中容易发生粘辊现象,导致钛板表面质量降低。为此,本实施例提供一种薄规格工业纯钛板的生产方法,具体的,参见图1,其包括:
S1:将钛材坯体加热,除鳞;
其中,所述钛材坯体选自工业纯钛材;优选的,采用TA2牌号的工业纯钛,所述TA2牌号工业纯钛的成分及含量为:0.01≤铁≤0.10、0.01≤碳≤0.05%、氮<0.008wt%、氢<0.008wt%、0.01≤氧≤0.15%,其他杂质含量<0.5%,余量为钛。杂质包括磷、硫、镍、硅、铝、锌等常见的残留元素。
在本发明中,对除鳞工艺没有具体的限制,可采用爆破法、机械法、变形法、高压水清除法对钛材坯体表面进行除鳞。为了更好的发挥本发明的优势,采用高压水冲洗除去钛材坯体表面的氧化铁等杂质;优选的,高压水的压力为9-18MPa;较高的水压力能够将钛材坯体表面的氧化铁等杂质充分脱除,保障钛板的优良性能。
S2:将除鳞后钛材坯体进行至少一次粗轧得到钛板坯体;
采用四辊可逆粗轧机对除鳞后坯体进行粗轧;优选的,在此步骤中,对钛材坯体进行3-5道次的粗轧;其道次压下量≤30mm,道次压下率≤40%。进一步优选的,对钛材坯体进行3道次的粗轧,各道次轧制量≤28mm;粗轧各道次轧制量的合理配合能提高轧制的效率,同时保证轧制质量,提高成品性能。
轧制过程中,开轧温度影响较大,一般选取合金相图中固相线温度的80%左右;在本发明中,充分考虑钛材的氧化、轧制性能等问题,采用开轧温度800-900℃,优选的为850-900℃,一方面确保了钛材坯体具有良好的塑性,易于轧制;另一方面,也尽量降低了钛材坯体表面的氧化,以防影响后续钛板的性能。
S3:将所述钛板坯体采用热轧机进行至少一次精轧,得到钛板;
其中,通过润滑系统在所述热轧机工作辊上喷涂润滑液。本发明的生产方法使得高温钛板与轧辊之间形成了一层稳定的轧制油膜,大大降低了钛板与轧辊之间的摩擦力,使得钛板轧制表面质量好,轧制过程稳定,板形平直,厚度控制精度高。
具体的,S3可分为:
S301:钛板坯体穿入热轧机机架;
S302:开启润滑系统的供水装置,向润滑系统的油水混合器供水;
具体的,供水装置供水的水压为3-7bar。
S03:开启润滑系统的供油装置,供给热轧润滑油;
具体的,所述润滑油的流量为0.5-0.8L/min;所述润滑油的压力为2-4bar。
进一步的,所述热轧润滑油由下述原料制成:中性机油75~85份、棕桐油5~7份、硫化蓖麻油1~2份、司本60 2~3份、吐温60 2~4份、油酸3~4份、三乙醇胺2~3份、活性物为10-12%的石油磺酸钠1~3份、磷酸三甲酚酯2~3份、苯并三氮哇1~3份。上述组分原料的热轧润滑油性能稳定,能在热轧过程中良好的阻断Ti-Fe之间的粘连。
需要说明的是,在采用辊缝润滑技术进行精轧钛板时,需要控制水与润滑油的供应顺序。具体的,先打开供水装置,再打开供油装置,以保证在精轧过程中喷嘴堵塞。进一步的,当轧机刚换轧辊时,需暂停使用润滑油,只开启水,待轧制几块钛板后,再开启润滑油,以防止润滑油粘附到轧辊表面,导致轧辊打滑。
此外,为了确保辊缝润滑精轧的效果,需要对喷润滑油的时序进行控制,具体的,在本发明中,采用7机架热轧机进行精轧;其中,当第一机架咬入钛板坯体后,打开各机架的供油装置;当第一机架抛出钛板坯体后,关闭第四机架的供油装置。
S304:所述水与热轧润滑油经油水混合器混合,得到润滑液;
S305:将所述润滑液采用喷嘴喷到工作辊整体辊身面。
具体的,控制所述喷嘴距离工作辊辊面的距离为80-100mm,此距离可确认喷嘴的安装角度以保证喷雾形状平行一致,使得辊缝润滑均匀充分。
具体的,在本发明中,精轧开轧温度≥700℃,精轧出口温度≥600℃,优选的为600-650℃。此温度范围可较好的控制钛板的金相组织,得到性能优良的钛板。精轧后,钛板的厚度为1.5-6mm。
S4:将所述钛板层流冷却、空冷后得到薄规格工业纯钛板成品;
具体的,在快速冷却设备中对精轧后钛板进行层流冷却,冷却终止温度为400-450℃。层流冷却一方面可以有效消除表面硬化层,使得在热处理过程中积累的氧化膜得到有效地消除,另一方面能使得热轧过程中在坯体内部集中的不均匀应力得到充分释放,同时也能够细化晶粒组织,改善了产品性能。
优选的,本发明中的生产方法还包括:
S5:卷取、检测、包装;
冷却后,采用卷取机直接进行卷取,卷取后进行检测、包装。
本发明采用辊缝润滑热轧的方法生产了薄规格工业纯钛板,其所需设备少,投入低;且工艺简单,生产成本低;制备得到的钛板各项性能优异,符合国家标准GB/T3621-2007和美国国家标准ASTM B265的要求,具有极高的推广价值。
