Light burned magnesia ball under new technology

Light burned magnesia ball is made of ordinary light burned magnesia powder and mixed with compressed ball. Light burned magnesia ball is mainly used for converter steelmaking, slag splashing and furnace protection. The preparation of lightly burned magnesium balls is to add 80% lightly burned magnesium powder into 20% water, and put it into a mixer for rolling, stirring, mixing for 15-2O minutes to form a mixture. The product is prepared by a belt conveyor and then stacked. After burning for 48 hours, the light burned magnesia balls are ready for sale.

Light burned magnesia ball is used as slag regulator for slag splashing in converter. Because slag splashing protection requires proper viscosity and refractoriness of slag, reasonable slag composition is the key to implement slag splashing protection. Generally, slag can not be splashed directly, and a certain amount of magnesia spheres should be added to adjust the slag. At the same time, the use of dolomite should be replaced to reduce the slag and increase the content of MgO in slag.

Magnesium oxide is a high melting point mineral, melting point is 2800 C, the content of magnesium oxide in slag is increased, the viscosity of slag is increased, refractoriness is improved, slag is easier to combine with lining, forming an effective slag protective layer on lining, thereby improving lining life and reducing consumption.

However, at present, the quality of light burned magnesium balls in the market is not uniform, from the choice of raw materials, to the production and processing of products, and then to transportation and sales, the pace of progress of each company is not uniform, resulting in customers and enterprises can not maximize the benefits. Some of the products that have not been reformed in the old production line of light burned magnesia ball have low ball rate. After the raw materials are processed by ball press, half of them are products and half are powder grains. The powder grains need to be manually returned to the ball press for further processing; the sphere is loose. Small density, low strength, easy to break. Especially when loading and unloading, transportation, extrusion and falling, the sphere is easy to break, and the shape of the ball is incomplete. Some are hemispheres, some are one-third of the ball, some are missing corners, shapes, surface gloss, poor appearance image; users are not satisfied. Among the products sold, there are 20% - 35% granules and powder mixtures, which users have raised objections many times; the most important thing is to increase the cost of customers and serious damage to the life of converter lining. Due to the loose, low density, low strength of lightly burned magnesium spheres, the spheres are loaded, unloaded, transported, extruded and dropped. It is easy to break. Therefore, when the lightly burned magnesium balls are fed into the steelmaking furnace and have not yet contacted with the molten steel, partially broken particles and powder particles are sucked out of the furnace by a strong negative pressure exhaust system at the top of the converter, collected by an electrostatic precipitator in the chimney and treated as waste, resulting in the following three results increasing the damage range of the lining of the converter To increase the damage degree of the exhaust system equipment and increase the consumption of light burned magnesia balls per ton of steel.

Light magnesia ball

Located in the production of "China Magnesium Capital", the lightly burned magnesium balls are strictly selected from the source of high-quality raw materials, carefully guided by engineers and strictly formulated according to customer requirements. Under the strict operation of the workers, they are pressed through a series of processes (weighing, adding water, mixing, conveying to the compactor, then conveying to the ball press and natural drying of the balls). It is. Huayi has always been relying on technological innovation to produce first-class products and continuous improvement.

At present, the lightly burned magnesia ball produced by the improved technology has reached the high-end level in the industry. Compared with the lightly burned magnesia ball produced by those companies which have not improved the technology, after many years of operation and production, the practice shows that the reformation not only improves the mechanization and automation of the lightly burned magnesia ball production line, but also improves the production ring. Environment has reduced labor intensity and improved labor productivity. At the same time, the existing problems before the transformation have also been significantly improved, the surface quality of the product has been significantly improved. The pelletizing rate of magnesium balls increased from 50% before transformation to 85% ~ 90% after transformation; the density of magnesium balls also increased; the drum index of structural strength of magnesium balls increased from 30% ~ 45% before transformation to 64% ~ 68% after transformation, which has exceeded the standard drum index by 58%. Especially during loading, unloading, transportation, extrusion and drop, the sphere did not break obviously, and the user did not raise any objection because of the surface quality of the lightly burned magnesium sphere.

It can be seen that the lightly fired magnesia ball products not only need to have a strict internal quality, but also need to pay attention to the appearance of the product quality, but also pay attention to the strength requirements of the product. Only enough product strength can have perfect appearance quality.

Continuously improve their own processes, improve product quality, reduce production costs, customers and enterprises to maximize the benefits of continuous efforts. According to the requirement of steel plant, the company also develops the products of light burning magnesia and magnesia-carbon spheres, using the oxygen-carbon reaction principle, reducing the iron oxide content in slag and the saturated solubility of magnesia, making the slag both refractory and viscous, satisfying the condition of furnace protection. Therefore, adding carbon in light burning magnesia spheres, that is, magnesia-carbon spheres. .
