GB/T 24531-2009 Standard Determination of iron ore drum and wear index for focused blast furnaces and direct reduction. It specifies test equipment, such as drum device specifications, detailing test procedures, including preparing iron ore samples, putting them into the drum to run under specific conditions, and then sieving and weighing them to calculate the index. The drum and wear index reflect the strength and abrasion resistance of iron ore, which directly affects the blast furnace and direct reduction process. According to this standard, enterprises and testing institutions can accurately determine relevant indicators, providing a basis for iron ore mass control and ensuring that it maintains good performance in industrial production.
