Build chrome-dolomite refractory

We committed to creating a chrome-dolomite refractory http://www.yknlxx.com According to the National Building Materials Association, at present China's cement kiln to use more "magnesia-chrome brick" as a refractory material. Formed at high temperature cement kilns and strong oxidizing working conditions, magnesium chromium debris after use will produce three times exceed European standards hexavalent chromium, according to an estimate, each producing 1.5 million tons of cement will be formed about 562 kg hexavalent chromium. Because of hexavalent chromium has strong Solubization, it will result in approximately ten billion tons of water pollution, and water pollution may be a direct threat to people's health. Chrome-free trend is determined to make the majority of refractory companies began developing new environmentally friendly products, in order to obtain broader competitive advantage, and as Brazil has 100 years of history, Magnesium, it is has been working non-chrome clouds refractory products R & D and sales. Recently, Brazil Magnesium non-metallurgical Refractories Asia Commercial Director, told China Cement Net Sun Jian told reporters that, since the 2008 acquisition of the world's largest producer of dolomite LWB, Brazil Magnesium strategic focus from LWB original stainless steel production Transfer to a cement kiln dolomite refractories. "In recent years the trend has become increasingly evident chromium-free, we believe dolomite refractory would be a very beneficial supplement, magnesium chrome brick strong alternative." Sun Jian expressed. Compared with magnesia chrome brick, dolomite brick features are obvious: 1, best value for money, high life than magnesium chrome brick, magnesite-chrome brick is lower than the price; 2, high life and high efficiency, low consumption of refractories ; 3, improve the quality of products; 4, to improve recovery and desulfurization efficiency chromium; 5, good environmental performance, do not pollute the environment. According to Sun Jian introduced, even though the current Brazilian Magnesium Refractory Sales in the steel industry accounted for a large proportion, about 60% -70%, but from a strategic point of the head office, the future will have a large proportion of focus in the building materials industry , including other non-ferrous metals industries cement, glass and nickel, copper, aluminum and the like.
