  • Research on measuring caking index using sand instead of standard anthracite

    HUANG Shan-xiu, MA Ming-jie (School of Materials Science and Engineering, Henan polytechnic University, Jiaozuo 454000, China)

    In order to seek a substitute of standard anthracite, do some research on the caking index of mixing coke which is mixed with quartz sand by the regulated ratio in standard(GB/T5447-1997), the results are so bad that need the new testing method. The testing results under different mixing ratio between quartz sand and mixing coke show that the coking index of mixing coke with quartz sand increases under the condition that the quantity of quartz sand in the mixture decreases, ant that G_2′/G and mixing proportion act as good linear regressive relationship. Based on the regressive equation, the corresponding equation between G_2′ and G is established. The further supplementary tests demonstrate that the coking index of mixing coke with standard anthracite firstly increases and subsequently reduces with the mixing proportion. When the mixing proportion is junior to 1:5, the coking index of mixing coke with standard anthracite is mostly equal to that of mixing coke. The comparison of approximate coking index of mixing coke with different supplements under different ratio indicate that the coking index of mixing coke with standard anthracite is senior to that of mixing coke with quartz sand and the gap enlarges with mixing proportion. A conclusion from nonlinear regression is drown that G_(2a)′/G_(2s)′ and mixing proportion have a excellent fitting relation.
