90m/s Wire Discharger


135m/s laying head
1. Equipment Application
The pinch roll and wire discharger are arranged after water cooling plant of finishing roll. The pinch roll is the device for steel line rolling production which mainly used for gripping rolled piece feeding into the wire discharger. Wire discharger for transportation of heliciform gripping rolled piece which diameter is 1080mm to the scattered coils cooling roll table before coil collector station.

2. Construction features of pinch roll & wire discharger:

Pinch roll and wire discharger are closely adjacent semi-open system. Pinch roll is arranged before entrance of wire discharger and transportation of gripping rolled piece into wire discharger. Then wire discharger will transform the gripping rolled piece to heliciform rolled piece which diameter is 1080mm and flat the rolled out to th the scattered coils cooling roll table.

It is the vertical cantilener structure and the center line slopes down ten degrees. It consists of spinning pipe which is installed in the rotation dabber and gearing. There is one DC adjustable-speed motor that could drive the rotation dabber through a pair of bevel gear wheel. Spinning pipe can spin regular wire coil on the basis of setting revolving speed.

Wire discharger rotation dabber consists of spinning head and hollow shaft. Spinning head is usede to fixation spinning pipe and hollow shaft. And the hollow shaft would been drived by bevel gear in the driving box. There is a pipe among the internal of bevel gear. And there is water-cooling drivepipe between the pipe and hollow shaft. Water-cooling drivepipe is used for cooling the pipe and it will protected the bearings of the hollow shaft to keep away from high temperature of rolled piece.
