Description

一种棒材φ16规格四切分孔型系统
技术领域
本发明涉及一种多线切分轧制系统,具体涉及一种棒材φ16规格四切分孔型系统,属于多线切分轧制系统技术领域。
背景技术
四切分轧制就是在轧制过程中,钢坯通过孔型设计轧制成四个断面形状相同的并联件,然后经切分设备将坯料沿纵向切分成四条断面形状相同的轧件,并继续轧制直至获得成品的轧制工艺;切分带部位毛刺,切口不规则,轧后易形成折叠,影响轧材表面质量,当剪切方法分开并联轧件时,轧件易扭转,影响轧件质量;切分轧制过程中,因受孔型系统参数、轧槽磨损、轧机弹跳、导卫安装、轧件宽展等因素的影响,各线轧件尺寸都不会完全一致,长度上表现为存在四线线差,重量上表现为存在的负偏差率差异大;现有的切分孔型系统两侧轧件米重负差大概率明显低于中间两线的负差,轧后中间负差接近国标上线,两侧负差仍有余量,造成重量损失,同时两侧料型明显偏大造成孔型磨损严重,造成轧辊不定期下线。
发明内容
为解决上述问题,本发明提出了一种棒材φ16规格四切分孔型系统,包括与预切分孔型、切分孔型以及切分前后精轧的孔型,可实现φ16四切分轧制过程中,延缓两侧孔型磨损,减少切分后各并行轧件的负差偏差的作用。
本发明的棒材φ16规格四切分孔型系统,包括K5孔型、预切分孔型孔型K4、切分孔型K3,椭圆孔型K2和成品孔型K1,所述预切分孔型孔型K4和切分孔型K3其切分时缩小两侧料型。
进一步地,所述K5孔型两侧轧件厚度为22mm,中间宽度为27.5,所述预切分孔型K4的槽口高度为7.8mm,槽底宽度21.4mm,辊缝宽度3.6mm;所述中间两线孔型切角为34°,两侧孔型切角为内39°、外33°,所述的切分孔型K3的槽口高度为1.4mm,槽底宽度20.6mm,辊缝宽度1.3mm,中间两线孔型切角为27.5°,两侧孔型切角为内30.75°、外35°。
K5孔型和预切分孔型孔型K4的设计,使两侧两线轧槽受力减小,避免两侧轧槽相对中间两线轧槽更快磨损,提高与切分轧辊使用寿命;且K5孔型和预切分孔型孔型K4的设计,中间两线轧槽受力增加,轧线宽展延伸从中间向两侧轧槽进行,提高了轧槽的充满度,降低了负偏差率的差异;另外,K3孔型中间槽口宽度与两侧辊缝宽度接近一致,使轧辊的调整余量接近最大值,提高了切分轧机的使用寿命。
本发明与现有技术相比较,本发明的棒材φ16规格四切分孔型系统,具有以下优点:
本发明所述的四切分孔型系统,在预切分时孔型深度相对来料料型偏差较小,中间孔型能够完全填充,减少两侧自由宽展,预切分孔型是保证切分孔型能顺利进行切分的过渡孔型,其目的是减小切分孔型的不均匀性,精确分配轧件的断面面积,尽可能减小负偏差率差异,从而提高切分的稳定性和均匀性;椭圆孔型K2、成品孔型K1在国标范围内对成品孔进行负偏差设计。
