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. 

A It can be divided into hollow roller table, solid roller table, circular roller table, patterned roller table and conical roller table, etc., which can be selected according to working conditions.

A There are feeding roller, front roller, back roller, transport roller, extension roller, working roller, collection roller and special purpose roller, such as in-furnace roller, lifting roller, cooling roller and inspection roller.

A Regularly lubricate all parts of the roller table, such as roller bearings and driving devices. Select a suitable lubricant and lubricate it according to the specified lubrication cycle.

A Regularly check the operation of the control system, such as whether the control buttons and indicator lights are normal. If there is any abnormality, it should be repaired in time.

A Regularly check the operation of the driving device, such as whether the temperature and noise of the motor, reducer and other equipment are normal. If there is any abnormality, it should be repaired in time.

A Check the wear of the rollers regularly, and replace the rollers with serious wear in time. At the same time, check whether the rotation of the roller is flexible. If it is stuck, it should be repaired in time.

A Regularly clean the impurities such as dust and oil on the roller table and keep the roller table clean. Compressed air, brushes and other tools can be used for cleaning.

A The mechanization and automation of continuous casting are relatively high, and the continuous casting process has been automatically controlled by computer, which frees the operators from heavy manual labor. In recent years, with the development of science and technology and the improvement of automation level, electronic computers are also used for the control of continuous casting production, all of which are controlled by computers except the casting operation. For example, the slab caster of Baosteel in China uses five PFU-1500 computers for on-line control, which has 3l control functions, such as cutting length calculation, compression casting control, electromagnetic stirring setting, on-line width adjustment of crystallizer, quality management, secondary cooling water control, process data collection, slab casting, tracking, finishing line selection, flame cleaning, slab printing label and weighing, and various report printing.
