API TR 977记录了API CRE耐火材料小组委员会和ASTM C08委员会联合开展的一个项目的结果，该项目旨在提高2015版ASTM C704/C704M《室温下耐火材料耐磨性标准试验方法》的再现性。抗侵蚀耐火材料用于许多炼油应用，如催化裂化装置（FCCU），以抵抗高温工艺环境中高速循环的固体颗粒的磨损效应。本技术报告还回顾了抗侵蚀耐火材料持续改进的驱动因素，以及ASTM C704/C704M在这些装置中使用的耐火材料的选择和安装质量控制中的作用。本报告记录了为提高试验再现性而对设置和程序所做的更改。 这些变更旨在实现这一目标，同时提供与变更前的历史数据一致的大致等效性。这些结果通过广泛的国际循环和耐用性测试的结果进行了验证，并在本文中进行了报告。

API TR 977 documents the results of a joint project conducted by the API CRE Subcommittee on Refractory Materials and the ASTM C08 Committee to improve the reproducibility of the 2015 edition of ASTM C704/C704M, Standard Test Method for Abrasion Resistance of Refractory Materials at Room Temperature. Erosion-resistant refractories are used in many oil refining applications, such as Fluid Catalytic Cracking Units (FCCUs), to resist the wearing effects of solids particles circulating at elevated velocities in a high-temperature process environment.This technical report also reviews the drivers for continuing improvement in erosion-resistant refractories and the role of ASTM C704/C704M for the selection and installation quality control of refractories used in these installations. This report documents changes made to the setup and procedures to improve the reproducibility of the test. These changes are designed to achieve this end, while providing a rough equivalency consistent with historical data before the changes were made. These results are validated by the results of extensive international round-robin and ruggedness testing, and are reported herein.
