Foreword
This standard is equivalent to international standards ISO 15967.2007 "DRI hot briquette iron drum and abrasion index determination" (English
Version).
For ease of use, this standard has been modified following editorial and non-technical difference of.
--- "This International Standard" by "this standard";
"." --- With a decimal point instead of a comma as the decimal point, "";
--- Delete foreword international standards;
--- References modify the corresponding national standards;
--- Rearrange the picture number and location;
--- According to the actual situation, an increase in 7.2 rubber door seal drum material;
--- 8.2 will tumble index and abrasion index is calculated in units of g to kg;
--- Chapter 9 test reports changed to Chapter 10, also made a non-technical content changes.

3 Terms and Definitions
The standards adopted GB/T 20565 in the terms and definitions.
Principle 4
The test sample in a circular drum, to 25r/min rotation speed of 200 rpm. Test samples with 6.30mm and after the drum test
Square hole sieve 500μm were sieved. After the drum index of particle size greater than 6.30mm drum test sample mass fraction of said wear means
With the number of particle size less than 500μm drum after the test sample mass fraction representation.
5 sampling, sample preparation and test sample preparation
5.1 Sampling and sample preparation
Sampling and sample preparation is carried out in accordance with ISO 10835.
Dried samples requires at least 70kg.
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.
Test sieve 40mm manual screening of samples discarded less than 40mm of section.
5.2 Preparation of test sample
The test sample paved rectangle layer on a smooth flat.
Test samples were randomly taken from the sample, to be prepared at least four test samples of about 15kg, followed by the test sample into the four containers.
The test sample was weighed, testing whether it satisfies the requirements of 15kg ± 0.5kg. If the test sample does not reach the quality of 15kg ± 0.5kg
Requirements, should come up with the remaining test sample piece of iron added to the test sample, or to come up with one piece of iron from the test sample and discard until trial
Test sample quality to meet the requirements. Record of each test sample quality.
