http://www.jialanrihua.com Light-burned magnesium balls are made of ordinary light-burned magnesium powder, which are pressed after mixing. It is mainly used for converter steelmaking and slag splashing to protect the furnace, which can increase the converter age. The preparation of light-burned magnesium balls is to add 80% light-burned magnesium powder to 2O% water, put it into a mixer to roll, stir, and mix for 15 to 20 minutes to form a mixture. The product is prepared through a belt conveyor and sent to the ball press. And then stack them. The finished product of light-burned magnesium spheres is dried in the shade for 48 hours and formed into strength, ready for sale.
Light-burned magnesium balls are used as slagging component regulators for converter slag splashing protection furnaces. Because the slag splashing furnace requires proper slag viscosity and fire resistance, reasonable slag composition is the key to the slag splashing furnace. General slag can not be directly splash-protected. It is necessary to add a certain amount of magnesia balls for adjustment, and instead of using dolomite, reduce the amount of slag and increase the content of MgO in the slag.
     As MgO is a high melting point mineral with a melting point of 2800 ° C and an increase in the content of MgO in the slag, the viscosity of the slag becomes larger and the fire resistance is improved. The slag is more easily combined with the lining, and an effective slag protective layer is formed on the lining, thereby improving the lining Life and reduce consumption.
After adopting this technology, a steel company in the United States now has a furnace age of nearly 20,000 furnaces and a converter operating rate of 97%. West Germany, South Korea, Japan, Taiwan, etc. are promoting this process. Many iron and steel enterprises are also actively developing their own slag splashing furnace protection technology, including TISCO, Chenggang, Heavy Steel, and Maanshan Iron and Steel. Since the slag splashing furnace protection technology has been adopted, the maximum furnace age has been 1,500 and 500 furnaces respectively. , 700 furnace, 1100 furnace to 12000 furnace, 1500 furnace, 8500 furnace, 10200 furnace, have achieved great economic benefits.
    However, the quality of light-burned magnesium balls on the market varies, and from the selection of raw materials to the production and processing of products to transportation and sales, the pace of advancement of various companies is inconsistent, resulting in neither customers nor enterprises can maximize the benefits. Some of the products produced by the old production line have not been transformed, and the ball formation rate is low. After the raw materials are processed by the ball press, half are the product and half are the powder. The powder needs to be manually returned to the ball press to continue processing; the spheres are loose. Low density, low strength and easy to break. Especially when loading, unloading, transporting, squeezing and dropping, the sphere is prone to breakage. The shape of the sphere is incomplete. Some are half balls, some are one-third balls, and some are missing corners, with different shapes, matte surfaces, and poor appearance; users are not satisfied. Among the products sold, there are mixtures of 20% to 35% small blocks and powders, and users have repeatedly raised objections to this; the most important thing is that it will increase customer costs and seriously damage the life of the converter lining. Due to the looseness, light density and low strength of the light-burned magnesium spheres, the spheres are easily broken during loading, unloading, transportation, squeezing and falling. Therefore, when the lightly burned magnesium balls are sent to the steelmaking furnace and have not come into contact with the molten steel, some broken pieces and powder particles are sucked out of the furnace by the strong negative pressure of the exhaust system on the top of the converter, and pass through the The electrostatic precipitator is collected and treated separately as waste, which results in the following 3 results: increasing the degree of damage to the converter lining, increasing the degree of damage to the exhaust system equipment, and increasing the consumption of light-burned magnesium balls per ton of steel.
       Strict selection of high-quality raw materials from the source, meticulous guidance by engineers, strict formulation according to customer needs, and strict operations by workers, through a series of processes (weighing, adding water and stirring, conveying to the compactor, and then to the ball press, ball eject Naturally dried) pressed. The factory has always insisted on relying on scientific and technological innovation to produce first-class products and continuous improvement.
       At present, the light-burned magnesium balls produced by our factory after process improvement have reached the high-end level in the industry. Compared with the light-burned magnesium balls produced by companies without process improvement, after 4 years of operation and production, practice has shown that: The mechanization, automation and other equipment levels of the light-burned magnesium ball production line have been improved, the production environment has been improved, labor intensity has been reduced, and labor productivity has been increased. At the same time, the problems existing before the transformation have also been significantly improved, and the surface quality of the products has been significantly improved. The spheroidization rate of magnesium spheres has been increased from 50% before transformation to 85% to 90% after transformation; the density of magnesium spheres has also been improved; the drum index of the strength of the magnesium sphere structure has been increased from 30% to 45% before transformation After the transformation, 64% to 68% have exceeded the standard drum index by 58%. Especially when loading, unloading, transporting, squeezing, and dropping, the spheres did not break obviously. At the same time, the users did not raise any objections due to the surface quality of the lightly burned magnesium balls.
      It can be seen that light-burned magnesium ball products not only need to have strict internal quality, but also need to pay attention to the appearance quality of the product, but also pay attention to the strength requirements of the product. Only enough product strength can have perfect appearance quality.
      The company continuously improves its own technology, improves product quality, reduces production costs, and continuously strives for the maximum benefit of customers and enterprises. The company also develops products based on the needs of steel mills: magnesium balls, lightly burned magnesium balls, magnesium oxide balls, lightly burned magnesium oxide balls, reducing the content of iron oxide in the slag and the saturation solubility of magnesium oxide, making the slag both refractory The degree and viscosity also make it easier for the slag to be combined with the furnace lining, forming an effective slag protection layer on the furnace lining, thereby improving the life of the furnace lining.
