The alkaline oxide pellet used for blast furnace ironmaking production in Baotou Steel is prepared with self-produced iron ore concentrate of Bayan Obo and part of Inner Mongolia magnetite concentrate by process of traveling grate-rotary kiln-rotating annular cooler. In the initial stage of industrial production of alkaline oxide pellet, the compactness of green pellet is poor, proportion of binder is high, compressive strength of finished pellet is low, amount of powder in process system is great and hot pellet is frequently discharged from rotating annular cooler so that on-site production is affected. In order to solve the above practical problems in pellet production, the performances of raw materials used in pellet production are optimized to improve compressive strength of alkaline oxide pellet. The specific surface area of raw materials used in pellet production is increased, compressive strength of alkaline oxide pellet is improved from 2 098 N to 2 358 N, amount of powder in process system is significantly reduced and the phenomenon of hot pellet discharged from rotating annular cooler is significantly reduced by processing the ore used for production of alkaline oxide pellet with the process of high-pressure roller grinding.

包钢以自产白云鄂博铁精矿为主,搭配部分区内磁铁精矿,应用链篦机—回转窑—环冷机工艺制备碱性氧化球团矿用于高炉炼铁生产。碱性氧化球团矿工业化生产初期,生球致密性差,粘结剂配比高,成品球抗压强度低,工艺系统粉末量大,环冷机下红料现象频出,影响现场生产。为解决上述球团生产实际问题,针对提高碱性氧化球团矿抗压强度进行了球团生产用料性能优化。通过运行高压辊磨工艺处理碱性氧化球团矿生产用矿,球团生产用料比表面积提高,碱性氧化球团矿抗压强度由2 098 N提高到2 358 N,工艺系统粉末量显著减少,环冷机下红料现象得到明显减少。

包钢以自产白云鄂博铁精矿为主,搭配部分区内磁铁精矿,应用链篦机—回转窑—环冷机工艺制备碱性氧化球团矿用于高炉炼铁生产。碱性氧化球团矿工业化生产初期,生球致密性差,粘结剂配比高,成品球抗压强度低,工艺系统粉末量大,环冷机下红料现象频出,影响现场生产。为解决上述球团生产实际问题,针对提高碱性氧化球团矿抗压强度进行了球团生产用料性能优化。通过运行高压辊磨工艺处理碱性氧化球团矿生产用矿,球团生产用料比表面积提高,碱性氧化球团矿抗压强度由2 098 N提高到2 358 N,工艺系统粉末量显著减少,环冷机下红料现象得到明显减少。

The alkaline oxide pellet used for blast furnace ironmaking production in Baotou Steel is prepared with self-produced iron ore concentrate of Bayan Obo and part of Inner Mongolia magnetite concentrate by process of traveling grate-rotary kiln-rotating annular cooler. In the initial stage of industrial production of alkaline oxide pellet, the compactness of green pellet is poor, proportion of binder is high, compressive strength of finished pellet is low, amount of powder in process system is great and hot pellet is frequently discharged from rotating annular cooler so that on-site production is affected. In order to solve the above practical problems in pellet production, the performances of raw materials used in pellet production are optimized to improve compressive strength of alkaline oxide pellet. The specific surface area of raw materials used in pellet production is increased, compressive strength of alkaline oxide pellet is improved from 2 098 N to 2 358 N, amount of powder in process system is significantly reduced and the phenomenon of hot pellet discharged from rotating annular cooler is significantly reduced by processing the ore used for production of alkaline oxide pellet with the process of high-pressure roller grinding.
