Study On Iron Ore Transportation Plan Of Ma Steel Based On Low Sulfur Cost

Iron and steel industry is the industry of a country life, and the iron ore is the main raw material of iron and steel enterprises, so the iron ore is a very important resource for the country. At present, the first of China’s iron ore output can be ranked in the world, but in the iron ore import volume ranking, China also has been tight in the first. The causes of this situation lies not in our industry is developed, but the average grade of ore in China and the global iron ore compared far apart, with the iron and steel industry development, leading to China’s dependence on imported iron ore greatly increased. Ma’anshan iron and steel Limited by Share Ltd is one of China’s large iron and steel enterprises, the upper reaches of the Yangtze River is located in Nanjing City, the geographical position is superior. Because the domestic iron ore production of poor quality, steel and high grade ores, ore quantity and Magang self-sufficient and less, most still need to import iron ore. In recent years, Australia with its excellent geographical location and rich ore production has become the biggest supplier of China’s imports of iron ore, iron ore imports each year more than half of the iron ore imported from australia. In recent years, air pollution has become the main pollution source port area. SOx is one of the most important, pollutant gas emissions from ships so, how to reduce the sulfur emission pollution has become the key issues.This paper on China’s imports of iron ore transportation situation analysis, combined with ore imports of Masteel to analyze it, in the third chapter, introduces the calculation method of sulfur dioxide emission status, trend of shipping and ship’s emission of sulfur. According to the trend in today’s society, energy-saving emission reduction, combined with the characteristics of shipping emissions, reducing sulfur emissions of ships based on the idea of adding sulfur emissions, cost in the operation cost, combined with the actual situation in Ma’anshan iron and Steel Group import Australian ore, after have on transport scheme, waterway and port etc. conditions were analyzed in detail, the number of arrange transportation shipping best path and each path in order to minimize the total costs, while the cost to achieve the purpose of energy saving.
