Description

This dataset is a market dataset. Each market represents the consumption portfolio of products within a specific geographic area, considering the transportation to consumers and the loss incurred during this process. This activity represents the supply of sinter for steel manufacturing consumption in China. The data is based on China's Customs Statistical Data, China Statistical Yearbook, and China Steel Yearbook.

Activity Description

This dataset is a market activity dataset, where each market represents a consumption mix of products within a specific region. The market covers producers and importers of the product within the same geographic area, considering transport to consumers and losses during this process.

Process Description

Sinter is a type of iron ore material used for iron smelting, typically produced by sintering iron ore powder with a certain proportion of coke powder, limestone, and other materials at high temperatures to form lump ore. The formation of sinter occurs through the heating treatment of mixed raw materials in a sintering machine, causing the raw material particles to bind together, forming lump ore with a certain strength and porous structure.

Technology comment

Sintering in steel plants is a critical pre-processing technique for steel production. Its main purpose is to form iron ore powder or other raw materials into lumps suitable for blast furnace smelting through high-temperature sintering. It mainly includes raw material preparation, molding, sintering, cooling, and processing. During the sintering process, raw materials are heated to high temperatures (usually between 1200°C and 1400°C). In this process, coke powder serves as a reductant and fuel, helping the ore powder particles to melt and bond into lumps at high temperatures.
