The spatial detection of rolling mill housing is the difficulty in rolling mill measurement. In the past, the measurement was with total station and inside micrometer, however, the measurement accuracy and technical indexes of this method could no longer meet the requirements of operating maintenance for rolling mill. In this paper, the method of measuring rolling mill housing with laser tracker is summarized. The centerline of rolling mill row is fitted according to the data of rolling mill housing collected by laser tracker as well as the coordinate system is established by taking the centerline of rolling mill row as the baseline so that such spatial position relationships as the centering size, window size and deflection of rolling mill housing could be obtained. The installation precision of rolling mill housing is recovered by adjusting the rolling mill housing based on the measurement data of laser tracker. This method is so reliable that it could be popularized.
