The Development of Scientific Management

With the development of scientific management, technology, and productive power, the products concerning the metal Magnesium have been developed in a diversified way involving Mg particle, Mg alloys, Mg powder, Mg ingot, Mg stick, Mg sacrificial anode and high performance sacrificial anode etc. The metal Mg, 2/3 density of the metal Aluminum, is one of the lightest metals. The potential application of the metal Mg is of great importance especially under today’s situation that energy has been greatly lacked of and environmental protection greatly emphasized. Having rich deposits under the earth, the metal Mg is of very good qualities like high anti-seismic capability, anti-corrosive capability and intensity etc., which makes it possible being the basic material for alloy industry and thereby wins itself great attention in the application of the national defense industry. Mg is easy to burn and give strong light in the air. Mg powder is used as the raw material of combustion and lighting bomb for defense. The metal Mg of national standard is not only sold well in domestic market but also exported to Japan, USA, Germany, India, Taiwan and Hongkong.
In the international market, more than 80 tons of Mg has been used in the desulphurisation of steel and iron each year. China is the main country in producing steel and iron, and it has been predicted by experts that China needs 300,000~500,000 tons of Mg for industrial processing from now on to the year 2005. The consumption of the metal Mg has increased with an average rate of 6.6% each year during 1990s. Additionally, 109,000 tons of Mg has been consumed in making various foundry products used in automobiles, motorcycles, and electric crust etc. Some spare parts that can be fitted to automobiles like wheel hub, instrument board, chair frame, gear box, direction system, cylinder, air inlet tube and brake pedal frame have been put into use in a wild areas. The consumption of the alloy Mg in automobile-making industry will
