Description

Constant tension transmission device structure for finish rolling outlet of hot continuous rolled steel coil Technical Field The utility model relates to the technical field of hot rolled coil production and manufacturing, in particular to a constant tension transmission device structure of a finish rolling outlet of a hot continuous rolled steel coil. Background The traditional hot continuous rolling steel coil is in a tension-free state from the outlet of the finishing mill to the coiling process (about 150 meters), the strip head and the strip tail of the steel coil are in wave-shaped transmission after exiting the outlet of the finishing mill, the thickness of the steel coil can fluctuate due to sudden tension of the steel coil at the moment of clamping the strip head of a coiling machine, the strip tail leaves the outlet of the finishing mill, the steel coil is in flying belt transmission due to tension loss of the steel coil, the steel coil is easy to stack, the thickness of the steel coil can suddenly fluctuate at the moment of tension loss, and the total thickness of the strip head and the strip tail affects about 300 meters (accounting for about 37 percent of the whole steel coil).
