Claims

[Scope of Claim for Utility Model Registration] 1. From rotors disposed at regular intervals on the circumferential surface of a roll in a molten zinc bath of continuous galvanizing equipment that does not contact the steel plate, and a detection member for detecting the rotors. A slip detection device for rolls in a molten zinc tank, which includes a roll rotation detection section, a slip detection device that compares the roll rotation speed and the moving speed of the steel plate, and issues an alarm signal when the difference exceeds a set value. 2. The roll slip detection device in a welded zinc bath according to claim 1, wherein the rotor is a concavo-convex member and the detection member is a vibrating rod. 3. A roll slip detection device in a molten zinc bath according to claim 1, wherein the rotor is a permanent magnet and the detection member is an exciting coil.
