Description
Technical field
The invention belongs to hot rollings to transmit field, and in particular to a kind of steel billet centralising device.
Background technique
It after hot continuous rolling steel billet goes out heating furnace, is transported by roller-way, removes removing iron scale into De-scaling box, even subsequently into heat
Mill milling.In this process, it may occur however that the case where steel billet sideslip misaligns, sideslip severest consequences can cause heat even
Milling train piling of steel is to damage equipment, although milling train flipper guide plays the role of guiding centering, acts on less, even serious sideslip
Flipper guide can be damaged under huge impact force.
Steel billet sideslip is such as the transport roller levelness as caused by many factors, and there are camber, wedge shapes can all lead for steel billet
Steel billet is caused to misalign, it is main at present using the method for increasing centralising device steel billet to be playbacked.
Centralising device structure is to be respectively arranged telescopic rod on steel billet both sides, by the push of rod piece, reaches steel billet centering
Purpose, the method have the following problems: 1) must in the case where steel billet reach predetermined position, push rod just works, therefore, right
The presence meeting of middle device so that production line length, it is especially outdated for newly-designed steel mill, do not meet short at present
The trend of process steel rolling;2) it must be equipped with that corresponding servo mechanism is synchronous with steel billet, while friction meeting strong during centering
Push rod end is damaged, without any buffering during entire centering, the service life to equipment is also one and greatly tests.
