摘要：
In amorphous strip fabrication, the stripe thickness is of the characteristics of the importance, which is decided by the velocity and flow of melting amorphous squirted from the jet, the distance between the jet and the cooling roller, and the rotating speed of the cooling roller. In this paper, a system is developed for the online measurement of the thickness of the amorphous strip, so that the machine can be adjusted accordingly in time to make sure the product meets its specifications. Considering onsite conditions in the workshop, laser triangle method combined with suitable software and hardware enhancement is proposed. The experimental performance of this measurement system was tested and verified in our laboratory and in a workshop in China.
