Lianxin Steel and Shandong Laigang Yongfeng order TMbaR mill from SMS group
TMbaR (Thermomechanical Rolling of Rebar) - one step ahead
(PresseBox) - For decades, SMS group (www.sms-group.com) has been a pioneer in and promoter of thermomechanical rolling. Now, two Chinese companies, Lianxin Steel and Shandong Laigang Yongfeng Steel, have decided to employ TMbaR, the process developed by SMS
With SMS group?s TMbaR process, it is possible to produce fine-grained final products while reducing the content of expensive alloys in the input stock.
Thermomechanical rolling is a forming process in which final reduction is carried out within a defined temperature range leading to specific properties of the rolled stock. Thus, sufficient capacity for cooling and equalization has to be provided for in the plant design. The lower rolling temperatures (750 to 820 degrees Celsius) require higher rolling forces and consequently wire rod blocks capable of sustaining very high loads. Under these rolling conditions, grain sizes that in conventional rolling would typically range between ASTM 8 and 10 can be improved to ASTM 12 with thermomechanical rolling.
Key components of the SMS group TMbaR technology are a loop line with water boxes for controlled cooling and equalizing and a MEERdrive
Two companies have now decided in favor of the TMbaR technology: Lianxin Steel and Shandong Laigang Yongfeng.
Lianxin Steel has ordered a TMbaR mill for its Dafeng site. The plant will be designed for an annual production of 1,000,000 tons of rebar with diameters ranging between 8 and 40 millimeters at a maximum rolling speed of 45 meters per second. SMS group will supply all rolling mill stands for the roughing, intermediate and finishing mills, including two six-stand MEERdrive
The TMbaR mill for Shandong Laigang Yongfengmeters between 8 and 25 millimeters to be rolled at a maximum speed of 45 meters per second and bar-in-coil in diameters ranging from 8 to 32 millimeters to be rolled at a maximum speed of 35 meters per second. Yongfeng is going to install two five-strand continuous casting machines supplied by SMS ) system for coils weighing up to five tons. Additionally, the electrical and automation systems for the three mechanical packages and supervision of erection and commissioning will be supplied. The plant is scheduled to start production in 2019.
Both companies put their trust in the long-standing experience of SMS group and its one-step-ahead TMbaR technology, which will allow Lianxin Steel and Shandong Laigang Yongfeng to respond better and faster to market demands, achieve improved material properties and save on alloys and operating costs.
