135m Laying Head for Rolling Mill

The 135m Model Laying Head

CZPT Application
The pinch roll and laying head are organized right after drinking water cooling plant of finishing roll. The pinch roll is the system for steel line rolling manufacturing which mostly employed 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 desk just before coil collector station.

CZPT attributes of pinch roll & wire discharger(laying head):
Pinch roll and wire discharger are intently adjacent semi-open up program. Pinch roll is organized before entrance of wire discharger and transportation of gripping rolled piece into wire discharger. Then wire discharger will change the gripping rolled piece to heliciform rolled piece which diameter is 1080mm and flat the rolled out to th the scattered coils cooling roll desk.
It is the vertical cantilener composition and the heart line slopes down ten degrees. It is made up of spinning pipe which is installed in the rotation dabber and gearing.There is one particular DC adjustable-pace motor that could push the rotation dabber through a pair of bevel equipment wheel.Spinning pipe can spin standard wire coil on the basis of setting revolving pace .
Wire discharger rotation dabber is composed 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 amid the inner of bevel equipment.And there is drinking water-cooling drivepipe among the pipe and hollow shaft .H2o-cooling drivepipe is utilised for cooling the pipe and it will guarded the bearings of the hollow shaft to hold away from higher temperature of rolled piece.
Wire discharger generate equipment box used welding framework. The equipment and bearings employed slender oil central lubrication approach.

Basic safety guard is the cylinder construction and the spinning head is installded in it .Its incline design is for the protection. Best 50 % of safty guard can been opened by the air cylinder for altering the spinning pipe but its have to been closed at typical operate. It should been processed static balancing check for all of the equipments with rotation dabber.Then we can increase or lower the excess weight of them on foundation of testting. Soon after static balancing test it should been processed dynamic harmony examination which measure datas are :testting rotate pace : 1900r/min, dynamic stability high quality : G2.5.There are two examination points in the entrance and back bearing cap when the wire discharger is assembled you could examination vibration info on the two details.And the check vibration masure knowledge is 5mm/s.
