Related introduction of magnesite products

  Magnesite is one of the advantageous resources in Liaoning province. Its reserves, production and export of magnesite refractory materials rank first in the world. Haicheng has accumulated proven reserves of 1 billion tons and designed annual production of 9 million tons. Liaoning magnesite has high grade, less impurities and high industrial utilization value. Among the proved total reserves, lm-46 and lm-45 grade magnesite reserves account for more than half of the total reserves, among which, lm-46 grade and above magnesite reserves account for about 40% of the total reserves. In addition, due to the economic development of the ore belt in the southern Liaoning hilly areas, road, rail transport is very convenient. These favorable conditions make the magnesite mining industry in liaoning develop rapidly and gradually form the magnesite production and supply base in China and even the world.

  HCAG can achieve a docking comprehensive production capacity of 1.9 million tons per year. Among them, 44 electric fused magnesia furnaces with an annual output of 150,000 tons of fused magnesia; Light burning reflection kilns 74, with an annual output of light burning magnesium powder 500,000 tons; 8 high-temperature oil-fired shaft kilns, with an annual output of 300,000 tons of high-purity magnesia; 12 vertical magnesite kilns with an annual output of 300,000 tons of re-fired magnesite; 2 bulk material production lines, annual processing of unshaped material 100,000 tons; 5 high purity furnace charge production lines (28 wet mills and 8 ball presses), with an annual output of 400,000 tons of pellets; Flotation production line 2, with an annual output of 150 thousand tons of high purity concentrate. High quality products, especially Ca/Si 2 high quality fused magnesia, high purity magnesia is unique in the world, play a decisive role in the upgrading of refractory materials, in the domestic and foreign markets enjoy a high reputation. Products sold domestic steel, non-ferrous metals, machinery, chemical and building materials industries. Over the years with Europe and the United States, southeast Asia, Russia, Japan, India and more than 20 countries and regions to establish a long-term stable relationship between supply and demand.

  Magnesia is one of the most important raw materials for refractory materials. It is used for manufacturing various magnesia bricks, magnesia bricks, ramming materials and charging materials. Containing more impurities, used for paving the bottom of the steel furnace. Light burned magnesium powder is a kind of material which can resist folding, pressure, high strength, air hardness and cementitious. It is widely used in national defense, medicine, chemical industry, papermaking, shipbuilding and other industries. In the building materials industry can be made of the tire board, particle board, insulation column, railing, artificial marble, asbestos tile, ordinary tile, wallboard, laid ground. With the progress of science and technology, the use of light burned magnesium powder is more extensive, can do civil products, weight and weight machinery packing boxes, packaging bottom beam, high temperature refractory materials, but also can make beautiful and generous gloss strong furniture, in the mechanical industry can do casting model.

  We sincerely welcome friends at home and abroad to negotiate and cooperate with us to bring the application of magnesia and magnesia products to all corners of the world and jointly open up a bright future.
