Description

Technical Field

[0001] The utility model relates to an independently driven conveying roller table of a multi-strand continuous casting machine, belonging to the technical field of mechanical equipment in the metallurgical industry. Background Art

[0002] At present, there are two ways of conveying rollers for multi-strand continuous casting machines. The first is to use a horizontally parallel integral roller, that is, the multi-strand continuous casting machine uses multiple common integral rollers to convey the billet. A motor and a reducer are installed at one end of each roller. Since multiple billets are conveyed at the same time, the load is large and the motor is easily burned and damaged; the second is to use a series of rollers with chains for each strand conveying roller. The most common is that a belt reducer uses 5 to 6 rollers through a chain. In this series roller, the chain is easy to fall and interrupt the conveying of the billet, and the continuous casting conveying drive system is mostly arranged under the conveying roller, which is not convenient for maintenance. In addition to their own shortcomings, these two ways of conveying rollers for multi-strand continuous casting machines are not suitable for the application and promotion of new process equipment such as online weighing, online numbering, and online deburring. In summary, it is inevitable to develop a conveying roller that is not affected by other strands and other rollers of one strand, and is suitable for new process equipment such as online weighing, online numbering, and online deburring.
