Foreword

This Standard was drafted in accordance with the rules given in GB/T 1.1-2009. This Standard replaces GB/T 5447-1997, Determination of Caking Index of Bituminous Coal. Compared with GB/T 5447-1997, the main changes are as follows. -- it adds the normative reference GB/T 483, General Rules for Analytical and Testing Methods of Coal (see Article 2); -- it adds the articles of reagent material and test report (Article 4 and Article 10); -- it modifies the rotating speed of the drum from (50 ± 2) r/min to (50 ± 0.5) r/min (see 5.1; 5.1.3 of edition 1997); and -- it changes the storage time of samples after preparation from “7 days” to “5 days” (see 6.2; 6.2 of edition 1997). This Standard was redrafted by modifying and adopting ISO 15585.2006, Hard Coal – Determination of Caking Index. Some adjustments in structure are made in this Standard, compared with ISO 15585.2006; Annex A lists the cross reference of the articles of this Standard and the articles of ISO 15585.2006.The main technical differences are marked with vertical single line (∣) in the page margins where the relevant articles are involved. Annex B gives the list of technical differences and their reasons. This Standard was proposed by China National Coal Association. This Standard shall be under the jurisdiction of National Coal Standardization Technical Committee of China (SAC/TC 42). The drafting organization of this Standard. China Coal Research Institute Testing Research Branch. The main drafters of this Standard. Xing Xiuyun, Li Hongtu, Chen Baohua and Chen Peng. The previous edition of GB/T 5447-1997 is as follows. -- GB/T 5447-1985. Determination of Caking Index for Bituminous Coal

1 Application Scope

This Standard specifies the method summary, reagent and material, apparatus, coal sample, test procedure, calculation of result, precision of test method and test report for the determination of caking index for bituminous coal.

2 Normative References

The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 474, Method for Preparation of Coal Sample GB/T 483, General Rules for Analytical and Testing Methods of Coal

3 Summary of Test Method

A portion of prepared sample of coal of limited mass range and the standard anthracite are mixed under defined conditions, and the mixture is carbonized rapidly. The crucible coke thus obtained is tested for strength in a drum conforming to certain specifications. Then the caking index (GR, I) is calculated to indicate the caking power of coal sample.

4 Material

4.1 Standard anthracite for the determination of caking index (hereinafter referred to standard anthracite). as specified in GB/T 14181.

5 Apparatus

5.1 Drum test apparatus, mainly composed of drum, transmission gear and motor, with the drum rotating speed of (50 ± 0.5) r/min. 5.2 Press, which is used for compressing the mixture of coal and standard anthracite under the weight of a 6 kg mass and placed on a stable and fixed platform (see Figure 2 for dimensions). 5.7 Analytical balance, capable of weighing to the nearest 0.001 g.

6 Coal Sample

6.1 Crush the sample of coal step by step to pass a 0.2 mm test sieve in accordance with GB 474.It is essential that 20 mass % to 35 mass % of the total sample consists of particles between 0.1 mm and 0.2 mm.

7 Test Procedure

7.4 Use the tongs to clamp the steel weight to place at the centre of the crucible, place it under the press, put down the pressure lever and apply pressure for 30 s. 7.5 After applying pressure, remain the steel weight on the mixture and cover it with the lid. 7.8 Remove the weight from the crucible; brush back into the crucible any particles of coke adhering to the weight. Weigh the total mass of coke. Transfer it to the drum and carry out the drum test (250 r, 5 min for each test).

8 Calculation of Result

8.1 When the proportion of standard anthracite and coal sample is 5.1, the caking index (GR, I) shall be calculated in accordance with Equation (1). 8.2 When the proportion of standard anthracite and coal sample is 3.3, the caking index (GR, I) is calculated in accordance with Equation (2).

9 Precision of Test Method

The critical differences of repeatability and reproducibility of the caking index of bituminous coal are as specified in Table 1.

10 Test report

The test report shall include the following particulars.
