輕燒鎂粉是一種重要的耐火材料 輕燒氧化鎂粉是一種具有中等堿度和化學活性的原料，除作為耐火材料和膠凝材料外，還應用于其他工業領域。另外，轉爐濺渣護爐技術的發展，輕燒鎂粉，進一步擴展了輕燒氧化鎂粉的應用范圍。目前，濺渣護爐技術多將輕燒氧化鎂粉成球后使用，有輕燒氧化鎂粉球、含碳輕燒氧化鎂分球和含碳含鈣輕燒氧化鎂粉球等。 輕燒氧化鎂粉，簡稱輕燒鎂粉，是一種由菱鎂礦、水鎂石和由海水或鹵水中提取的氫氧化鎂經800~1000℃左右煅燒所獲得活性氧化鎂。輕燒鎂粉為呈淡黃色、淡褐色的粉末，粒度大都在100目以下，方鎂石結晶很小，密度
Light-burned magnesia powder is an important refractory material. Light-burned magnesia powder is a raw material with medium alkalinity and chemical activity. In addition to being used as refractories and gelling materials, it is also used in other industrial fields. In addition, the development of converter slag splashing furnace protection technology, light burning magnesium powder, has further expanded the scope of application of light burning magnesium oxide powder. At present, slag-spattering furnace protection technology mostly uses light-burned magnesia powder into balls, including light-burned magnesia powder balls, carbon-containing light-burned magnesia balls and carbon-containing calcium-containing light-burned magnesia powder balls. Light-burned magnesia powder, referred to as light-burned magnesia powder, is a kind of activated magnesium oxide obtained by calcining magnesite, brucite and magnesium hydroxide extracted from seawater or brine to about 800 ~ 1000 ℃. Light-burned magnesium powder is a light yellow and light brown powder with a particle size of less than 100 mesh.
The light-burned magnesium ball is prepared by adding 80% light-burned magnesium powder to 2O water, putting it into a mixer, rolling, stirring, and mixing for 15 to 20 minutes to form a mixture. The product is prepared by sending the ball to a ball press through a belt conveyor. 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.
Improvement of Light Burned Magnesium Ball Production Process
1Necessity of light magnesium powder production process improvement
After many years of production practice in our factory, the light-burned magnesium ball products are produced according to the above preparation process, and the quality of the products has the following problems.
1) The sphere is loose. Low density, low strength and easy to break. Especially when loading, unloading, transporting, squeezing and dropping, the spheres are easily broken.
2) 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 returned to the ball press manually.
3) The user is not satisfied. The products sold contain 2O% -35% small blocks and powders, and users have repeatedly raised objections to this.
4) The shape of the sphere is incomplete. Some are half balls, some are one-third balls, some are missing corners, have different shapes, and have a matte surface.
