Implementation of Automated Tapping system in Jiangsu

13 June 2019

Chinese steel producer Jiangsu Shagang Group Company Limited (Jiangsu Shagang) placed an order with Primetals Technologies to install automatic tapping system on two BOF converters in its converter steelworks in Zhangjiagang in Jiangsu Province. This modernization project marks the first commercial implementation of Primetals Technologies’ Automated Tapping system in a steelworks. The package will reduce tapping time and minimize slag carry-over, improving subsequent phosphorous refining. Automated tapping sequences will optimize tapping performance and make it independent from the operator’s experience. In addition, working safety will be largely improved. Start-up of the new Automated Tapping systems is expected for the Q3 of 2019.

Automated Tapping system

The Automated Tapping system developed and installed by Primetals Technologies acts as a “Digital Assistant” and allows for a safe and fully automatic converter tapping procedure, including the control of vessel position, ladle car movement during tapping, as well as the positioning of the chute for ladle alloying. In combination with an installed slag identification system, e.g. optical or magnetic slag detection and a slag stopper system, there is minimal carry-over of converter slag in the teeming ladle.
