Research on Influencing Factors of Grinding Efficiency Difference between Mass Production and Small Batch Experiment of the Mixtures AITranslate
Abstract AITranslate
A small batch of YG-type cemented carbide ZD10 was prepared using the same WC and Co raw materials as mass production. The grain sizes of the alloys produced by mass production and small batch were analyzed by metallograpbic microstructure observation and cross-section method, and their coercive force and cobalt magnetism were also detected. The grinding efficiency of large and small batches was com- pared, and the factors were analyzed influencing the grinding efficiency difference between large and small batches. After grinding for 24 h with the same grinding process, the grinding efficiency of the small batch is higher,its average HCP value is 0. 025 （kA/m）/h higher than that of the large batch. The grinding effi- ciency is comparable between grinding for 18 h of the small batch and grinding for 24 h of the large batch. When the grinding time for mass production is determined at 24 h,the average coercive force of each batch of the alloy is 11.36 kA/m,which is exactly the median value of the internal control standard （10.4~12 kA/m） and can meet the needs of users. All the filling coefficient of alloy rods,rotating speed of mill barrel and internal structure of mill barrel are influencing factors of grinding efficiency difference between large and small batches.
