The dry type magnetic separator is commonly used iron ore and manganese ore beneficiation equipment. It is the mainstream strong magnet separator‚ which is specialized in processing dry magnetic minerals. The wet type magnetic separator use liquid diluents to improve separation efficiency. The dry type magnetic separator requires that the material must be dry‚ and can move freely between the particles. Or it will affect the separation result‚ and even cannot separate materials. The magnetic system

Steel is actually a mixture of iron with a small percentage of carbon. By using different ratios of iron to carbon‚ different properties are obtained for different steels. What are some different properties that might be valuable for different types of steel? Hardness‚ flexibility‚ density‚ etc. VI. Discussion:

Blast Furnace Hot Metal is one of the most critical problems in today’s Iron Making. With deterioration in quality of iron ore day by day‚ silica load in the burden material has a steady increase. The same story is with the Coke ash‚ which passes good amount of silicon in the hot metal. Every 0.1% reduction in silicon in the hot metal gives rise to 1.5 % increase in hot metal production. In the competitive scenario of today’s Iron Making hence it is necessary to reduce every bit of Silicon in hot metal

Chinese invention is the development of iron and steel. The development of iron and steel led to other advances. In the 4th century the Chinese had developed blast furnaces to obtain cast iron from iron ore. The Chinese had access to large amounts of clay; clay was the most important ingredient in making blast furnaces. The Chinese also figured out that by adding a substance they called "Black Earth‚" they could lower the melting point of iron. Today iron and steel are used in many things from clocks
