GB/T 4000-2017
ActiveDetermination of coke reactivity index (CRI) and coke strength after reaction (CSR)
焦炭反应性及反应后强度试验方法
Application Summary AI generated
This standard specifies the test method for determining the coke reactivity index (CRI) and coke strength after reaction (CSR), which are critical quality indicators for metallurgical coke used in blast furnace ironmaking. It is applied in the steel industry and coke production facilities to evaluate coke performance under high-temperature CO₂ conditions, ensuring optimal fuel efficiency and structural integrity in blast furnace operations. The standard is also used for quality control and acceptance testing of coke in procurement and trade between suppliers and steel manufacturers.
