在冶金企业中,炼钢厂的粉尘污染比较严重,可以说仅次于耐火材料厂。我厂的原料、平炉、铸锭和整模现场有很多尘源点,其中原料车间散状料场是我厂粉尘污染最严重的地方。这座散料场储存平炉炼钢用的镁砂、白云石、铁矾土等干料。这些干料在卸车、输送和装槽过程中扬起的粉尘浓度相当大,经过测定周围空气含尘浓度高达1000毫克/米~3以上,特别是在卸车和装槽过程中,粉尘的污染使操作岗
In the metallurgical enterprises, steel mills dust pollution is more serious, we can say second only to refractories plant. I plant raw materials, open hearth furnace, ingot and mold site a lot of dust source point, of which raw material workshop bulk material yard is the most polluted place of our factory dust. This bulk yard storage blast furnace steel with magnesia, dolomite, bauxite and other dry materials. These dry materials in the unloading, transportation and loading of the process of raising the dust concentration is quite large, after the determination of the surrounding air dust concentration as high as 1000 mg / m ~ 3 above, especially in the dump truck and loading process, the dust pollution operation
