Manur Nuclear Power Produces Domestically Heaviest Slender Withdrawal-Type ESR Ingot
On August 30, 2026, the 60t withdrawal station of the 150-ton-class atmosphere-protected electroslag remelting (ESR) furnace at Yantai Taihai Manur Nuclear Power Equipment Co., Ltd. successfully produced a slender ESR ingot with a diameter of approximately 1270 mm and a weight of 61.2 tons, setting a new record for domestically manufactured special metallurgy equipment and consolidating the equipment foundation for the supply of high-end nuclear power forgings. The 61.2-ton slender withdrawal-type ESR ingot produced this time features a regular appearance and excellent surface quality. During the smelting process, equipment and operations including atmosphere protection, melt rate control, precise molten metal level control, fully automatic electrode exchange, and the complete withdrawal process remained stable and controllable. This ingot is currently the heaviest slender withdrawal-type ESR ingot produced in China, representing another critical leap in domestically manufactured large-tonnage withdrawal-type ESR equipment...
