巴西利亚钢铁公司的福斯特尔(F6rster)线材研究所推出了一种用于冷拉拔线材的新型检测设备。该设备于1986年底投入运转。 该设备设计成终端监控优质钢(例如轴承钢)线材的冷拉拔。它配备有涡流检查仪,带旋转传感系统的循环图以及带扫描线圈的探伤仪。 沿纵向及横向表面检测诸如裂纹、疏松、缩孔等缺陷。 Brasilia Steel’s F6rster Wire Research Institute introduced a new inspection facility for cold drawn wire. The equipment was put into operation by the end of 1986. The device is designed to end-monitor the cold drawing of high-quality steel (such as bearing steel) wire. It is equipped with an eddy current tester, a cycle diagram with rotation sensing system, and a flaw detector with scanning coil. Defects such as cracks, looseness, shrinkage cavities are detected along the longitudinal and lateral surfaces.
