Guilin Pinggang is privately owned and located in Pingle near Guilin city in Guangxi Province. The enterprise has an annual production capacity of 1.2 million metric tons, and produces rebars, wire and other steel elements for the construction industry. Primetals Technologies has supplied the complete mechanical and electrical process equipment for the new EAF Quantum electric arc furnace and the twin ladle furnace. The balance of plant auxiliary equipment and services have been provided by a local design institute.
The EAF Quantum developed by Primetals Technologies combines proven elements of shaft furnace technology with an innovative scrap charging process, an efficient preheating system, a new tilting concept for the lower shell, and an optimized tapping system. This achieves very short tap-to-tap times. The electric energy consumption is considerably less than that of a conventional electric arc furnace. Together with the lower consumption of electrodes and oxygen, this gives an overall advantage in the specific conversion cost of around 20 percent. In comparison to conventional electric arc furnaces, total CO2 emissions can also be reduced by up to 30 percent per metric ton of crude steel.
