Recently, Baosteel Special Material successfully smelts the first furnace of engine material steel for Rolls-Royce, with performance indicators all meeting user requirements. After passing Rolls-Royce management system requests and hazard assessments, Baosteel Special Material officially enters the product certification stage.This means that Baosteel Special Material has taken a critical step in entering Rolls-Royce's global sourcing directory.
Rolls-Royce is a famous aero-engine company in Britain and is Europe's largest aviation engine company. The jet engines developed by the company are widely used in global civil and military aircrafts. Along with GE, they are known as the two heroes in aero-engine field. At present, as Airbus A380 large aircraft engine supplier in the modern wide-body aircraft engine manufacturing field, Rolls-Royce occupies 50% of the global market share.
In the entire process of aircraft manufacturing, aircraft engine requires largest investment, longest development cycle and incurs greatest technical difficulty. It is the key point which impacts the entire aircraft performance and reliability. Therefore, especially in the field of civil aviation, engine material selection is stringent and there are high standards and requirements for suppliers' process control capacity and product quality stability.
Baosteel Special Material has nearly forty years of aerospace special material research and development and manufacturing experience. The products are widely used in Long March series of carrier rockets, Shenzhou series of spacecrafts and Chang-e lunar exploration satellite and other cutting-edge manufacturing technologies. It is an importance production base of China's aerospace materials. In recent years, Baosteel Special Material vigorously promotes civil aviation material production, sales and research. On the one hand, it increases investment in manufacturing unit large-scale technological transformation, introducing special smelting equipment such as multiple sets of large vacuum induction furnace and vacuum consumable electrode melting furnace and building isothermal forging production line; on the other hand, it makes great efforts to improve site, improve management, set up high standards and strict requirements and looks up to international standards. It has passed AS aviation infrastructure quality standard system, as well as Nadcap system initiated and developed by U.S. aerospace and defense industry giants, U.S. Department of Defense and SAE and targeted for aerospace industry specific special products and process certification. On this basis, it actively explores the field of civil aviation material market and achieves good results. A number of civil aviation materials are advancing smoothly.
In the past two years, Baosteel Special Material has had numerous exchanges with Rolls-Royce. Early this year, based on previous audit and communication, the two sides formally assert cooperation intention. Baosteel Special Material successively passes Rolls-Royce "supplier management system requirements" audit, hazard assessments and technical audit, and recently it officially enters the product certification stage. Baosteel Special Material's pioneering in the field of civil aviation engine materials not only has good market prospects, but also support the progress and development of domestic engine material field.
