Analysis on evaluation of uncertainty of caking index of bituminous coal
This articleestablishes a mathematical model based on the measurement data of the bituminous coal bonding index.It analyzes the sources of uncertainty in the measurement results of the bituminous coal bonding index from aspects such as the total mass of coke residue after coking treatment,the mass of material on the screen after the first drum rotation,the mass of material on the screen after the second drum rotation,the final result numerical rounding,and the repeatability of measurements.The standard uncertainty components for each source and the combined standard uncertainty are calculated to ultimately obtain the uncertainty of the bituminous coal bonding index measurement results.
