Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard is modified using ISO 7373. 1987 "Ferroalloy - Test Method for Scaling Indication of Samples" (English version). This standard structure and technical content (except for normative references) are consistent with ISO 7373. 1987; normative references GB/T 4010 instead of ISO 4552, with GB/T 28369 instead of ISO 7087. This standard is proposed by China Iron and Steel Industry Association. This standard is under the jurisdiction of the National Technical Committee on Standardization of Pig Iron and Ferroalloys (SAC/TC318). The drafting of this standard unit. Sinosteel Group Jilin Ferroalloy Co., Ltd., Metallurgical Industry Information Standards Institute. The main drafters of this standard. Liu Xiancheng, Wang Shuang, Chen Zhibin. ferroalloy A test method for checking the shrinkage accuracy of a sample

1 Scope

This standard specifies the test method for checking the shrinkage accuracy of ferroalloy samples. The test is carried out using a large sample or a pair of samples Is taken in accordance with the method specified in the relevant standard from the ferroalloy delivery. This standard applies to crusable ferroalloy samples and is not intended for use with drilled non-destructible ferroalloy samples.

3 General requirements

3.1 large sample weight GB/T 4010 provides ferrochromium, silicon chromium alloy, ferrosilicon, manganese silicon alloy and ferromanganese and other ferroalloy delivery batch weight should not be less than 100t, GB/T 4010 in the provisions of iron, molybdenum, tungsten iron, ferroniobium and ferroalloy iron and other ferroalloy delivery batch weight should not be less than 5t, so for this test, large The amount of sample is sufficient to produce the required weight of the sample. 3.2 Analytical methods The sample analysis shall be carried out in accordance with the method specified in the relevant standards. 3.3 Quality characteristics Check the quality characteristics of the sample shrinkage accuracy should be specified in the relevant standards. Negotiated by the parties concerned, you can also use other elements as a quality feature. 3.4 Number of tests Each ferrous alloy, whether large or sub-sample, should be tested at least 10 times. Note. The sample can be taken to determine the quality of the delivery batch.
