提出一种新型高温钢坯长度在线测量系统。它采用三块线阵ＣＣＤ摄象机的技术方案，对于钢坯±１５°以内的偏摆和±１４００ｍｍ的中心偏移，能进行有效的测量，由于生产现场的限制，ＣＣＤ摄象机只能安装在高温钢坯的侧面。测量系统能在恶劣的现场条件下可靠地工作。测长相对误差≤±０．６３％，满足生产的需要。
A new type of high-temperature billet length online measurement system is proposed. It adopts the technical scheme of three linear CCD cameras and can effectively measure the deflection within ± 15 ° and the center offset of ± 1400mm. Because of the limitation of the production site, the CCD camera can only be installed On the side of the hot billet. The measurement system works reliably under harsh field conditions. Measuring the relative error ≤ ± 0.63%, to meet the production needs.
