本文阐述了《焦炭反应性及反应后强度试验方法》标准修订的编制情况、主要技术指标的确定情况,以及与GB/T4000-2008版的不同点。修订后的标准实施后将进一步提高该检测方法的精密度,为焦化炼铁生产提供可靠性的数据,为焦炭和焦煤的商品贸易提供检验依据。
This paper describes the “coke reactivity and post-reaction strength test method” standard revision of the preparation of the main technical indicators to determine the situation, and the GB / T4000-2008 version of the difference. After the implementation of the revised standards, the precision of the testing method will be further improved to provide reliable data for the production of coking iron and provide the test basis for the commodity trade of coke and coking coal.
