Description

Technical Field

[0001] The present invention relates to the field of fixed-width press mechanical equipment, in particular to SMS fixed-width press opening degree measurement, and more specifically, to a fixed-width press opening degree calibration tool and a working method thereof. Background Art

[0002] At present, the opening of the hammer head of the fixed-width press is still measured by tape measure and flat ruler for centering and opening. The measurement position is different and the user's measurement method is different, so the final measured data will be very different. Therefore, the measurement error using tape measure and flat ruler is relatively large. The measurement error will cause problems with the centering and opening of the fixed-width press, which not only affects the width of the slab, but also causes the centering of the hammer head of the fixed-width press to be poor. The force on both sides of the hammer head of the fixed-width press is uneven during the rolling process, causing the slab to bend sideways, and in severe cases, it will make it difficult for E1 to bite the steel.

[0003] In view of the above problems, a device for accurately calibrating the opening degree of a fixed-width press is needed on site to achieve accurate and rapid measurement of the opening degree and centering degree of the fixed-width press. The present invention designs a calibration tool for the opening degree of a fixed-width press. Summary of the invention
