Description
This is a market dataset. Each market represents the consumption mix of products within a specific geographic region, accounting for transportation to consumers and associated losses during this process. The activity represents the supply of sinter ore from China to steel manufacturing consumption activities. The data are based on China Customs statistics, China Statistical Yearbook, and China Iron and Steel Industry Yearbook.
Activity Description
This dataset is a market activity dataset, where each market represents a consumption mix of products within a specific region. Markets cover producers and importers of the product within the same geographical area, considering transportation to consumers and associated losses during this process.
Process Description
Sinter is an iron ore raw material used in ironmaking, typically formed into lump ore by mixing iron ore fines with a certain proportion of coke fines, limestone, and other raw materials, which are then fused together at high temperatures. The formation of sinter involves heating the mixed raw materials in a sintering machine, causing the particles to bond and form a lump material with certain strength and porous structure.

Technology comment
Sintering in steel plants is a crucial pretreatment 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 process mainly includes raw material preparation, forming, sintering, cooling, and processing. During sintering, the raw materials are heated to high temperatures (typically between 1200°C and 1400°C). In this process, coke fines act as both a reducing agent and fuel, facilitating the melting and bonding of ore particles into solid lumps under high temperature.
