The Importance of Rolling Mill Rollers

The importance of the rolling mill roller table in the rolling mill cannot be replaced, and the reasonable arrangement of the roller table can greatly save the rolling time of the steel rolling production line and the labor intensity of the workers. For example, the working roller table arranged before and after the working stand of the rolling mill and the roller tables arranged before and after the blooming mill are all working roller tables. The reclaiming device is the key equipment for reclaiming the billet from the feeding platform to the feeding roller table.

With the acceleration of the production efficiency of the rolling mill,  the requirements of the reclaiming device for the conveyance of the billet are increasing. The billet reclaiming device in front of the heating furnace uses a hydraulic cylinder to drive the crank link mechanism to complete the lifting and translation of the billet. The billet reclaiming device has reasonable structure and stable operation, which basically has no impact and noise on the billet and the roller table, improving the service life of the rolling table of the rolling mill.

The working conditions of the working rollers of rolling mills and billet rolling mills are the most onerous. In addition to frequent starting and braking, they also need to withstand the impact load caused by rolling and turning of rolled steel during rolling. The working roller table generally adopts the structure type of collective drive of the bevel gear. The new type one is the one-way two-way transmission device for the rolling roller table.

The roller is connected with the transmission device by a curved tooth coupling to adapt to the change of the center height of the roller when the buffer spring is deformed. The motor shaft is equipped with a gearbox. The main drive gear is in meshing contact with the gearbox’s internal teeth. The roller shaft is installed on the roller table. The bevel gear is installed at the front end of the roller shaft, and the bevel gear meshing with it is installed on the main drive shaft.

When the motor rotates, two-way transmission of power can be achieved through the bevel gear. In order to reduce the impact load on the roller, the buffer spring is installed under the roller bearing. This device has the advantages of simple structure, low cost, reliable operation and power saving, and is suitable for small and medium-sized steel rolling mills.
