Primetals Technologies supplies EAF Quantum electric arc furnace and ladle furnace to Langxi County Hongtai
- Electrical energy consumption per metric ton of liquid steel is very low, as are operating costs and CO2 emissions
- Short project duration
Primetals Technologies has received an order from Chinese steel producer Langxi County Hongtai Steel Co., Ltd. (Langxi County Hongtai) to supply an EAF Quantum electric arc furnace and a ladle furnace for its plant in Xuancheng, Anhui Province. The EAF Quantum furnace is designed to handle scrap steel of vary varied composition and quality. The electrical energy requirement of the electric arc furnace is extremely low because the scrap is preheated. This reduces both the operating costs and the CO2 emissions. The twin ladle furnace sets the desired steel grades and the correct casting temperature. The new furnaces are scheduled to be commissioned in the third quarter of 2019.
Langxi County Hongtai was founded in 2002. The company's business includes the manufacturing of steel castings including alloy, bushings, and rolling mill rolls. For the new EAF Quantum electric arc furnace and the twin ladle furnace, Primetals Technologies will supply the complete mechanical and electrical process equipment and the automation technology. This includes the automated scrap yard management, the automated charging process, automation of the oxygen injection and sand refilling, as well as the Level 2 automation which makes the plant ready for Industry 4.0.
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 all adds up to very short melting cycles. The electricity consumption is considerably lower 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.
