Detailed Description

Unless otherwise specified, the terminology herein is to be understood in light of the knowledge of one of ordinary skill in the relevant art.

The axial direction herein refers to the axial direction of the axis of rotation of the roller shaft or the conveying hub.

"the steel billet is by cutting position" indicates in continuous casting billet production process, the continuous casting steel billet after the shaping is cut according to the size of the length that requires in the transportation, on some production lines now, establish movable cutting torch travelling bogie in the suitable position of transfer passage top, in the steel billet is by the transportation, cut through the cutting torch that is located its top, the steel billet after the cutting continues to be carried along transfer passage, consequently be equipped with mobilizable cutting torch on the continuous casting transfer passage of some steel billet continuous casting steel billet production lines, the position and the steel billet of taking place the cutting in carrying are by cutting position.

The utility model discloses an end surface is inclined plane or arc surface promptly in two sides that axially are relative in the deflector, and is greater than or equal to 90 jiaos with the surface of node about, when the steel billet is through the node that is equipped with the wire guide, if when touch deflector inner arc surface or inclined plane, can be in time corrected the direction of advance automatically.

The utility model discloses a concrete continuous casting steel billet direction is carried scarfing cinder device is shown in 1-2, include a plurality of rollers 5 that set gradually along steel billet direction of delivery, one of them or a plurality of rollers are the drive roll axle, the last motor that is connected with of drive roll axle, be equipped with wheel hub 7 on every roller, the roller passes and carries wheel hub or carry wheel hub both ends installation roller, every wheel hub's axial both ends are equipped with ring shape deflector 3, a plurality of wheel hub form the transfer passage of transportation continuous casting steel billet for carrying the node in proper order, every wheel hub constitutes the node on the transfer passage, ring shape deflector exceeds wheel hub's surface, and ring shape deflector is the cambered surface along two sides that the axial is relative, and the back wheel hub surface that lies in steel billet cutting position simultaneously is equipped with spiral shape scarfing cinder sword.
