石油焦型号怎么分类？

【专家解说】：石油焦 硫含量 挥发分 灰分 水分 真密度（1300℃ 5小时煅烧） 粉焦量（块粒8mm以下） 硅含量 钒含量 铁含量 一级品 ≤0.5% ≤12% ≤0.3% ≤3% 2.08-2.13g/cm3 25% ≤0.08% ≤0.015% ≤0.08% 1#A ≤0.5% ≤10% ≤0.3% ≤3% 实测 实测 ≤0.08% ≤0.015% ≤0.08% 1#B ≤0.8% ≤12% ≤0.5% ≤3% 实测 实测 ≤0.08% ≤0.015% ≤0.08% 2#A ≤1.0% ≤12% ≤0.5% ≤3% 实测 实测 ≤0.08% ≤0.015% ≤0.08% 2#B ≤1.5% ≤15% ≤0.5% ≤3% 实测 实测 ≤0.08% ≤0.015% ≤0.08% 3#A ≤2.0% ≤16% ≤0.8% ≤3% 实测 实测 ≤0.08% ≤0.015% ≤0.08% 3#B ≤3.0% ≤18% ≤1.2% ≤3% 实测 实测 ≤0.08% ≤0.015% ≤0.08% 主要是看硫含量，
