At early stage of bar production line, open-train mill is main equipment but people discover its inadequacy and limitations.
In order to reach more high yield with lower cost, factories optimize rolling process and improve performance of equipment and process. In result, the semi-continuous rolling mill replaces the open-train mill, and now the continuous rolling mill is widely used to produce bar& wire rod line and greatly enhance production yield.
- The continuous rolling line has clear advantages than other production processes.
- Further improving production efficiency.
- Save energy: The continuous rolling line can save 30% energy than semi-continuous rolling process, because of the billet hot delivery hot loading.
- To enhance Automation level of the production line.
- Behind the furnace equipped high pressure water descaling, that can improve surface quality of final products.
- Mill stands are arranged by Horizontal and vertical alternately, full line is to no-twist rolling process.
- The mills are short stress rolling mills, it is handy to adjust symmetrically the roller gap. The stand as a whole to be replaced, there is less on-line adjustment.
- Mill drive adopts DC drive or AC speed regulation drive to realize stepless speed regulation of the rolling line.
- Rebar production line applies slitting process to increase yield.
