New building materials are building materials products that have developed rapidly in recent years. With its fire resistance, environmental protection and other advantages, it has won the favor of domestic and foreign experts and scholars in the construction industry. The famous "Bird's Nest" for the 2008 Olympic Games has maximized the use of new building materials and combined with high-tech to create world-class cutting-edge building projects.
Among the raw materials of new building materials, the most commonly used is "light calcined magnesium powder". Light calcined magnesium powder is made from magnesite and calcined in light calcined reverberatory kiln, rotary kiln or fluidized bed furnace. The product is calcined evenly, with stable quality, high purity and good activity. It can be widely used in papermaking, chemical industry, refractory materials, building materials, desulfurization and other industries.
Light burned magnesium powder is used to make refractory materials. The steel industry is the largest consumer of magnesium products in the United States and most countries. The calcined magnesia obtained from magnesite, sea water, salt lake or well salt is mainly used in the manufacture of refractory products for metallurgical furnaces. Light burned magnesium powder is widely used in various fields. In the water treatment industry, calcined magnesium powder is used to remove silicon in water and heavy industrial waste liquid; It can also be used as a neutralizer for the treatment of industrial waste gas. The calcined magnesium powder can react with SO2 in the flue gas to generate magnesium sulfate, thus removing SO2 in the industrial waste gas, which is better than the sulfur removal effect of calcium compounds. Another purpose is to produce magnesium oxychloride and magnesium oxysulfide cement for manufacturing industrial and civil building floors.
In short, the raw material of light burned magnesium powder will become a more hot demand target with the development of new building materials industry, and the wholesale volume of light burned magnesium powder will also increase.
In addition, with the arrival of autumn, the weather will gradually turn cool, until the cold and deep winter, the purchase volume of light calcined magnesium powder will probably increase slightly, and the price of light calcined magnesium powder will also increase, and the specific trend remains to be observed.
After adopting this technology, an iron and steel company now has a furnace life of nearly 20000 and a converter operation rate of 97%. West Germany, South Korea, Japan, Taiwan and other countries are implementing this process. Many iron and steel enterprises are also actively developing their own slag splashing furnace protection technology. Since the adoption of slag splashing furnace protection technology, the maximum furnace life has been increased from 1500, 500, 700 and 1100 furnaces to 12000, 1500, 8500 and 10200 furnaces respectively, which has achieved huge economic benefits.
However, the quality of calcined magnesium balls in the market is mixed. From the selection of raw materials, to the production and processing of products, to the transportation and sales, the pace of progress of each company is not consistent, resulting in the inability of customers and enterprises to maximize benefits. Some products produced by the old production lines that have not been transformed have a low balling rate. After the raw materials are processed by the ball-pressing machine, half are products and half are powder particles. The powder particles need to be manually returned to the ball-pressing machine for further processing; The sphere is loose. Low density, low strength, easy to break. Especially during loading and unloading, transportation, extrusion and falling, the ball is easy to break and the shape of the ball is incomplete. Some are half a ball, some are a third of a ball, some are missing corners, different shapes, matt surface, and poor appearance image; The user is not satisfied. The products sold contain 20% - 35% mixture of small particles and powder particles, which users have raised objections for many times; The most important thing is that it will increase the cost of customers and cause serious damage to the service life of converter lining masonry. Due to the loose, small density and low strength of the light-burned magnesium ball, the ball is easy to break during loading, unloading, transportation, extrusion and falling. Therefore, when the light-burned magnesium ball is sent into the steelmaking furnace and has not yet contacted with the molten steel, part of the broken block particles and powder particles are sucked out of the furnace by the strong negative pressure of the exhaust system on the top of the converter, collected by the electrostatic precipitator in the chimney and treated separately as waste, resulting in the following three results: increase the damage degree of the converter lining masonry, increase the damage degree of the exhaust system equipment, and increase the consumption of the light-burned magnesium ball per ton of steel.
