Description

一种基于摩擦辊作用的复合带异温轧制方法及设备 技术领域
本发明属于金属复合带制备技术领域，具体涉及一种基于摩擦辊作用的复合带异温轧制方法及设备。
背景技术
金属复合带是一种兼具结构和功能性的层状复合材料，具有多种优良金属的性能，近些年来被广泛应用到石油化工、航空航天、国防军工、交通运输和家用电器等领域，金属层状复合带的推广应用对解决当前能源结构、产业结构的突出问题具有非常重要的意义。常见的金属复合带有钢/铝，铜/铝，镁/铝等，这些复合材料在冶金、化工、电器等行业领域的应用受到极大重视。目前，生产金属复合带的方法主要有轧制法、挤压法、爆炸法和扩散焊接法等。相比于其他结合工艺，轧制复合具有无噪声，对环境影响小，生产环节可控，生产效率、成材率高，产品尺寸规模大等优点，逐渐发展成为生产金属复合带的主流方式。
对于异种金属轧制复合带，普遍存在的问题是异种金属在相同温度条件下变形抗力不同，使异种金属变形不协调，导致金属复合带结合强度低，且易发生边浪、中浪等板形问题，异温轧制是一种促进异种金属变形协调的有效轧制方式。
目前对复合板带异温轧制的方法有：分别对不同金属加热到指定温度(CN 109226263 A)；只对单一板进行加热(CN 106862271 A)；电磁感应加热(CN 105598166A)。第一种方式存在过程冗长、热量散失等问题。第二种方式通过热传导使两种金属产生温差，但温度控制不精确。电磁感应加热只适用于顺磁 性金属，对于其他金属加热速度缓慢。总之，上述复合板带异温轧制的方法存在耗能大，工序复杂繁琐，局限性大等问题。
发明内容
本发明针对上述问题提供了一种基于摩擦辊作用的复合带异温轧制方法及设备。
为达到上述目的本发明采用了以下技术方案：
一种基于摩擦辊作用的复合带异温轧制方法，包括以下步骤：
S1、准备金属待复合带，对金属待复合带的待复合面进行表面处理；
S2、通过若干组摩擦辊加热装置对金属待复合带进行摩擦加热，并通过温度检测仪对摩擦加热后的金属待复合带表面温度进行测量，根据测量到的温度调整摩擦辊加热装置中摩擦辊的转速；
S3、将加热后的金属待复合带输送至轧机进行轧制，得到金属复合带，其中所述步骤S2中摩擦辊的旋转方向与轧机轧辊的旋转方向相反。
进一步，所述步骤S2中的摩擦辊加热装置包括两个支架，在所述支架内部设置有两个轴承座，且位于下部的轴承座固定设置，位于上部的轴承座活动设置，在位于上部的轴承座的上表面连接有压下装置，所述压下装置安装在支架上，在两个支架上对应的轴承座内设置有摩擦辊，所述摩擦辊的一端通过万向轴与减速器的输出轴连接，所述减速器的输入轴与电机的输出轴连接。
再进一步，所述摩擦辊加热装置中摩擦辊轴线方向与金属待复合带轧制方向的夹角
Figure PCTCN2020136955-appb-000001
大于0°，小于等于90°。
更进一步，所述摩擦辊对金属待复合带的压下作用在其弹性变形范围内。
更进一步，所述摩擦辊为高速旋转辊，转速为2000-20000r/min。
一种基于摩擦辊作用的复合带异温轧制设备，包括上下放置的两个金属带放卷器、温度检测装置、导向辊、轧机和复合带收卷器，在每个金属带放卷器后方设置有若干组摩擦辊加热装置，所述金属带放卷器、摩擦辊加热装置、温度检测装置、导向辊、轧机和复合带收卷器的安装顺序依次为金属带放卷器、摩擦辊加热装置、温度检测装置、导向辊、轧机、导向辊、复合带收卷器，所述摩擦辊加热装置包括两个支架，在所述支架内部设置有两个轴承座，且位于下部的轴承座固定设置，位于上部的轴承座活动设置，在位于上部的轴承座的上表面连接有压下装置，所述压下装置安装在支架上，在两个支架上对应的轴承座内设置有摩擦辊，所述摩擦辊的一端通过万向轴与减速器的输出轴连接，所述减速器的输入轴与电机的输出轴连接。
与现有技术相比本发明具有以下优点：
1、本发明在金属复合带轧制过程中使用摩擦辊加热装置，利用高速旋转的摩擦辊与金属待复合带摩擦生热作用，通过调整摩擦辊转速在异种金属中产生不同的热量，从而产生不同的温升，实现金属复合带异温轧制，也可实现一侧金属待复合带单独加热；
2、本发明在金属复合带轧制过程中使用摩擦辊加热装置，一组摩擦装置中的上、下摩擦辊表面粗糙度可不同，与金属待复合带上下面接触时产生不同的摩擦系数，结合摩擦辊的压下与高速旋转作用，使金属待复合带沿厚度方向形成有利的温度梯度，从而有利于金属复合带的结构和力学性能；
3、本发明在金属复合带轧制过程中使用摩擦辊加热装置，缩短金属待复合带升温所需时间，减少热量散失，通过温度检测装置反馈调控摩擦辊转速，实现金属复合带在线精确控温；
4、本发明在金属复合带轧制过程中使用摩擦辊加热装置，通过金属表面与 摩擦辊接触，将热量从金属表层传递至整个金属，降低了异种金属相互之间的温度影响作用，使异温轧制效果显著；
5、本发明在金属复合带轧制过程中使用摩擦辊加热装置，其中摩擦辊作用在金属带上的摩擦力方向与其轧制方向相反，由此可以产生张力，有利于金属复合带减薄，提高生产效率，张力大小由摩擦辊压下位移、转速及表面粗糙度协调控制。
