Principle 4 At 1050 ℃, the sample while applying the static load of the bed, which leads to carbon monoxide, hydrogen and nitrogen gas mixture of test samples Reduction until the reduction reaches 80%. When the test sample reduction of 80%, the measurement sample and the sample gas pressure bed bed height variation. 5 sampling, sample preparation and test sample preparation 5.1 Sampling and sample preparation Sampling and sample preparation according to GB/T 10322.1 performed. Size pellets and lump ore should be between 10.0mm ~ 12.5mm. Drying the sample size distribution described above requires at least 6kg. Samples at 105 ℃ ± 5 ℃ oven drying to constant weight, and then cooled to room temperature. Note. If two consecutive dry sample varies no more than 0.05% by mass of the original sample is considered state of the sample constant weight is reached. 5.2 Preparation of test sample Test samples were randomly taken from the sample. Note. The test sample can also be obtained by GB/T 10322.1 in bipartite and other manual reduction of sub-methods. From a sample of at least 5 parts of the test sample to be prepared about 1200g, each test sample weighed to the nearest 1g. Wherein, for the four test Mortem, 1 for chemical analysis.
