标准摘要
[中文适用范围]： 此文件规定了用于测定块状焦炭（公称顶尺寸>20 mm）在二氧化碳气体中高温下的反应性及其在圆柱形室内翻滚后在二氧化碳气体中的反应后强度的设备和技术。主要应用是测试用于高炉炼铁的焦炭（CRI<33，CSR>55）。本标准也可应用于其他类型的焦炭（例如铸造焦炭），但预计精度有限。应用于非高炉炼铁焦炭的范围超出本文件的规定。 [外文原描述]： ISO 18894:2018 specifies the equipment and techniques used for determining lump-coke (nominal top size >20 mm) reactivity in carbon dioxide gas at elevated temperatures and its strength after reaction in carbon dioxide gas by tumbling in a cylindrical chamber. Main application is the testing of coke to be used in iron making blast furnaces (CRI~ < 33, CSR~ > 55). This standard can also be applied to other coke types (e.g. foundry coke), but limited precision is to be expected. Application to coke for non-iron making blast furnaces is beyond the scope of this document.
英文名称Coke — Determination of coke reactivity index (CRI) and coke strength after reaction (CSR)
