    使用輕燒鎂球的好處有那些?輕燒鎂球是一種堿性耐火製品,CaO的作用:可以取代石灰中的CaO,保證煉鋼終渣堿度,減少石灰加入量。CaO能與爐渣中的SiO2反應CaO+SiO2=3CaO.SiO2、Ca2SiO4,C3S、C2S都是高熔點物質,如果爐渣中的CaO含量足夠的話,輕燒氧化鎂球的主要成分以MgO為主既可。 雖然通過調整爐渣中MgO的操作,可以達到降低爐渣過熱度和稠化爐渣的目的,但是利用C—O反應C(FeO)=Fe+CO,降低爐渣中FeO含量和MgO的飽和溶解度,使爐渣中的MgO更容易達到或超過飽和值。從而改質爐渣既有較高的耐火度又有適宜的粘度,滿足濺渣護爐的條件,因此也可以在輕燒氧化鎂球中適當增碳。

What are the benefits of using lightly burned magnesium balls? Light-burned magnesium ball is an alkaline refractory product. The role of CaO: it can replace CaO in lime, ensure the alkalinity of the final steelmaking slag, and reduce the amount of lime added. CaO can react with SiO2 in the slag. CaO SiO2 = 3CaO.SiO2, Ca2SiO4, C3S, and C2S are all high-melting substances. If the content of CaO in the slag is sufficient, the main component of lightly burned magnesia balls is mainly MgO. Although the operation of MgO in the slag can be adjusted to reduce the slag superheat and thicken the slag, the C—O reaction C (FeO) = Fe CO is used to reduce the FeO content in the slag and the saturation solubility of MgO, so that the MgO is more likely to reach or exceed saturation. Therefore, the modified slag has both a higher fire resistance and a suitable viscosity, which satisfies the conditions of slag splashing to protect the furnace, so it can also appropriately increase carbon in light-burned magnesia balls.

輕燒鎂球   使用輕燒鎂球主要有四大好處:
1、適合濺渣護爐的爐渣堿度:R(CaO/SiO2)約3.5左右
2、合適的留渣量(噸鋼):90---100Kg/t
3、適當的濺渣時間:2--4min
4、控製終渣MgO值:
5、終渣MgO含量(推薦值%)選擇合適的輕燒鎂球:≤MgO≧45%,根據轉爐終渣情況適當調整輕燒氧化鎂球的成分。
    基於上述理論、實踐與研究,本公司營口菠萝蜜视频在线針對煉鋼的時候起到賤渣護爐的作用。增加爐齡壽命,降低煉鋼成本。


There are four major benefits to using lightly burned magnesium balls:

1. Slag alkalinity suitable for slag splashing furnace: R (CaO / SiO2) is about 3.5

2. Appropriate slag retention (ton steel): 90 --- 100Kg / t

3. Appropriate slag splashing time: 2--4min

4. Control the final slag MgO value:

5. The final slag MgO content (recommended value%) Select a suitable light-burned magnesium ball: ≤MgO ≧ 45%, and adjust the composition of the light-burned magnesium oxide ball according to the condition of the converter's final slag.

     Based on the above theory, practice, and research, the company's Yingkou Bohai Magnesite plays a role in protecting slag when making steel. Increase furnace life and reduce steelmaking costs.
