GB/T4000《焦炭反应性及反应后强度试验方法》标准修订综述

Review on Revision of GB/T4000 Standard for Coke Reactivity and Test Method for Post Reaction Strength

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 preparation of revised standards for coke reactivity and post reaction strength test, the determination of major technical indexes, and the differences with GB/T4000-2008 version. After implementation of the revised standards, accuracy of the method will be further improved, which will provide reliable data for coking and iron-making and provide test criteria for trade of coke and coking coal.
