17.06.2021. In March 2021, Tangshan Heavy Plate issued Primetals Technologies with the final acceptance certificate (FAC) for three Mold Expert systems for the continuous casters at the Laoting plant in the Tangshan region of China. The new systems have been installed to increase efficiency even more in the prevention of breakouts on the continuous casters and cut the amount of maintenance work. Reducing the frequency of breakouts will also help to lower production costs.
Primetals China commissioned the new systems on site with online support from experts at Primetals Austria. Despite travel restrictions, the project was realised within just three months. Before the order was placed, Primetals ran and supported a six-month test installation on one of the casters.
Increased plant availability, less time spent on maintenance, and reduced production costs
Tangshan Heavy Plate has invested in three Mold Expert systems for its existing continuous casters at the Laoting plant in Tangshan in China. The new solutions from Primetals have been installed to increase system availability at the Laoting plant and reduce the amount of time spent on maintenance by issuing prompt alerts. Apart from preventing breakouts, the system also transmits alerts in the event of abnormal casting conditions and evaluates the behaviour and distribution of the mold powder. Continuous recording of information and experiences in the Mold Expert system results in more efficient prevention of breakouts in real-time operation, thus avoiding high costs for repairs and production outages. The system provides data for process optimisation and supports the operator in his work. The software can be easily scaled to meet the customer’s specific needs.
Custom configuration of system hardware
In the standard configuration, each Mold Expert system is deployed with one computer for measuring tasks and a separate client PC. However, to fulfil the customer’s wishes and requirements in this specific project, a particularly “slim-line” version of the system was implemented with the entire software installed on just one computer in the operator room for each continuous caster.
Efficient project execution despite travel restrictions
Employees from Primetals China successfully carried out commissioning on site with experts from Primetals Austria assisting online whenever their help was needed. Despite travel restrictions, the project was realised within just three months. Commissioning was greatly facilitated by information on the plant gathered by analysing actual data during a prior six month test installation. Furthermore, the teams from Tangshan Heavy Plate and Primetals had the opportunity to develop a relationship based on mutual trust during the six-month test phase. This was a further important element in ensuring smooth-running commissioning.
