Description
Sinter can be used as a high-quality iron ore for ironmaking; the dataset includes major raw materials, auxiliary materials, energy consumption, atmospheric emissions, and waste generated during the production process, while infrastructure such as production equipment manufacturing and plant construction is not included within the system boundary; the life cycle inventory is compiled from data obtained from multiple sources; the sintering process involves mixing raw materials such as iron ore fines, coke fines, and limestone, followed by sintering and cooling, resulting in a lumped ore product suitable for blast furnace smelting.
Activity Description
The production process of sintered ore involves mixing raw materials such as iron ore powder, coke fines, and limestone, followed by sintering and cooling, ultimately forming lump ore suitable for blast furnace smelting.
Process Description
Sinter is a lump ore produced by mixing iron ore with a certain proportion of coke, limestone, and other raw materials, followed by thermal processing at high temperatures. Sinter is an important form of iron ore and can be used as high-quality iron ore in ironmaking.

Technology comment
Sintering in steel plants is a key preliminary process in steel production, primarily aimed at agglomerating iron ore fines or other raw materials into lump materials suitable for blast furnace smelting through high-temperature sintering. The main steps include raw material preparation, shaping, sintering, cooling, and treatment. During the sintering process, the raw materials are heated to high temperatures (typically between 1200°C and 1400°C). In this process, coke fines act as both a reductant and fuel, facilitating the melting and binding of ore particles into solid lumps under high temperatures.
