在线、棒材生产中需要及时了解所轧制的钢材的直径以供调整轧机之用,迄今沿用的是靠人工截取之后再用卡尺测量的办法,既不准确又不及时也不安全,而且无法连续不断地获得数据,以至产品质量难以保证,因此,很需要研制精确的在线检测装置。 本文介绍的这一系统已在攀钢线材厂A,B两条轧制生产线上连续使用了三年,测量对象是以3.5m/s速度运动的φ17mm的圆钢,它实现了同时对两条生产线的产品的在线多方位测径,分辨率为1/1500,测试精度为±0.06mm,具有完备的图形和数字显示及统计分析功能。
Online, bar production needs to keep abreast of the diameter of the rolled steel for the adjustment of the rolling mill, so far it has been used by manual interception and caliper measurements, neither accurate nor timely and not safe, and can not Continuous access to data, and even the product quality is difficult to guarantee, therefore, it is necessary to develop accurate on-line testing device. The system described in this article has been used continuously for three years in the two rolling lines A and B of Panzhihua Iron and Steel Wire Rod Factory, measuring φ17mm round bar moving at a speed of 3.5m / s, Production line of multi-directional product diameter, resolution of 1/1500, the test accuracy of ± 0.06mm, with a complete graphic and digital display and statistical analysis.
