| Abstract: | Determining the highest permitted concentration of respirable dust and analyzing content of silicon dioxide in 1390 determination spots in 25 plants in seven iron and steel corporations. Respirable dust density distribution is divided into 3 kinds,which can be draw various density distribution column charts and collective distribution charts,the first,second,third kind of average density distribution of respirable dust is 2.49mg/m 3,7.14mg/m 3,22.1mg/m 3.Distribution law of SiO 2[F] content is less than 10%,73%;10%~50%,25.5%;more than 50%,1.5%. |
