GB/T 24241-2009 《Direct reduced iron - Determination of the tumble and abrasion indices of hot briquetted iron(HBI)》 Related products

The GB/T 24241-2009 standard specifies the determination method of the drum and wear resistance index of hot-pressed iron blocks in direct reduced iron. It details the required test equipment, such as the specification requirements of the drum testing machine, and specifies the test steps, including the preparation of hot-pressed iron block samples, loading the drum and running at a specific Rotation speed and time, followed by screening and weighing to calculate the drum and wear resistance index. These indices reflect the strength and abrasion resistance of hot-pressed iron blocks and are essential for evaluating the mass of direct reduced iron. Through this standard, manufacturers and related testing institutions can accurately determine relevant indicators to ensure the Stability of direct reduced iron in subsequent processing and use.
