Currently, one of the main constraints on the automotive aluminum large number of applications is its high price better than Which refractory steel, aluminum alloy in order to facilitate the large number of applications in the automotive refractory species, must reduce material costs. In addition to the development of low-cost aluminum and advanced aluminum forming processes outside refractories sales, recycling technology can further reduce the cost of production of aluminum alloy. Another research direction to expand the application of aluminum is to develop a new variety of connectivity technologies, multi-material structure of the car's future development requires the connection of two different types of materials (such as cast-aluminum, steel-aluminum, aluminum-magnesium, etc.), These connections technology and surface treatment technology for anti-corrosion materials and components, the future expansion of aluminum in automotive applications an important issue. The total sample of Anshan, Yingkou, Dalian, Jinzhou, Panjin and other five regions 89 production of 112 batches of magnesia refractories (magnesite refractory) products, qualified 105 batches of product sampling with a pass rate of 93.8%. Among them, 75 magnesia refractory materials production enterprises, 85 batches of products were random inspection, product sampling pass rate of 100%; magnesia refractory products for 17 of the 27 batches of products manufacturing enterprises were random inspection, 10 production of 20 batches of product sampling qualified, product sampling pass rate 74.1%. Magnesia refractory products, product sampling situation magnesium (aluminum) exists mainly brick nonconformity is apparent porosity, bulk density, load softening starting temperature, the heating of permanent change, thermal shock resistance; major nonconformity exists magnesia-chrome brick is the porosity; the presence of magnesium and calcium brick main unqualified items are apparent porosity, bulk density, load softening starting temperature. The provincial special supervision for product quality checks reflected in the quality of refractories, Liaoning Province Bureau of Quality Supervision requires the relevant units should strictly follow the "People's Republic of China Product Quality Law," "product quality supervision and inspection management approach" and other laws regulations, take effective measures, good product quality supervision and inspection of substandard products manufacturer post-processing work to ensure product quality and safety.
