A There are three types: collective transmission, individual transmission and traveling. The first two types are widely used, especially the individual transmission mode develops rapidly, and the traveling roller table is rarely used. Collective transmission is mainly used in areas with harsh working conditions, heavy workload and high ambient temperature. Usually, it is used to transport short and thick rolled pieces, such as roller table in front of furnace and behind furnace, roller table before and after rolling mill, etc.
This transmission mode complicates the roller table, but the roller table uses less electrical equipment, consumes less energy, is convenient for several kinds of ventilation, is easier to manufacture and has less investment. The single drive roller table is mainly used in areas with light workload, slender rolled pieces and low temperature, such as finishing areas. The main advantages of the roller table with independent drive are small flywheel torque, easy starting and braking, rapid roll change independently, convenient maintenance without affecting production, easy adjustment of roller height, simple structure, light weight, easy processing and easy standardization. Compared with the collective drive, the roller table has higher cost and higher inertia when running.It is not easy to stop, so it is not easy to choose the rolled piece that requires accurate stop.
