Limestone treatment process suitable for steel mill
The invention discloses a limestone treatment process suitable for a steel mill, which comprises the following steps: S1, washing limestone before being used in a raw material bin, and washing off mud in the limestone before being used in the raw material bin; s2, the mud washed away in the step S1 is pressed into cakes, and limestone particles with the diameter smaller than the preset diameter in the washed limestone before use in the raw material bin are subjected to water filtration and then used for sintering; and S3, screening out limestone particles with the diameter larger than the preset diameter from the washed limestone before use in the raw material bin, and feeding the limestone particles into the bin for lime production. A set of limestone washing process is built by combining the current production process with the site condition and utilizing the site, the limestone before entering a bin for use is washed, mud and impurities in the limestone are washed away, mud is pressed into cakes, small particles are subjected to water filtration and then are used for sintering, and the limestone meeting the requirements is screened out and enters the bin for lime production. In thought, the operation efficiency of the rotary kiln is improved, the product quality is obviously improved, and the environmental protection meets the national requirements.
本发明公开了一种适合钢厂的石灰石处理工艺，包括：步骤S1:对进原料仓使用前的石灰石进行水洗，将进原料仓使用前的石灰石中的泥洗掉；步骤S2:将步骤S1洗掉的泥巴进行压饼，将洗过的所述进原料仓使用前的石灰石中小于预设直径的石灰石颗粒滤水后用于烧结使用；步骤S3:洗过的进原料仓使用前的石灰石中大于预设直径的石灰石颗粒筛选出进仓用于石灰生产。通过目前的生产工艺，结合现场情况利用场地建设一套石灰石水洗工艺，对进仓使用前的石灰石进行水洗，将其中的泥和杂质洗掉，泥巴进行压饼，小颗粒滤水后用于烧结使用，筛选出符合要求的石灰石进仓用于石灰生产。一言以蔽之，提高回转窑的运行效率，产品质量提高明显，环保达到国家要求。
