Calcination, Sintering, Limestone, Combined Model 1. Introduction Sintering refers to changes in pore shape, pore shrinkage and the the increase in stone size that CaO particles undergo during heating. The rate of CaO sintering increases at higher temperatures, as well as at higher partial pressures of carbon dioxide and steam vapor.
Limestone – Its Processing and Application in Iron …
Application of limestone and lime in iron and steel plant. During the production of iron by blast furnace (BF) route, limestone is added either in the process of sintering or as a direct feed in the blast furnace. Limestone is normally added during ironmaking for obtaining either neutral or slight basic BF slag.
Sintering - Wikipedia
Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.. Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, plastics, and other materials.The atoms in the materials diffuse across the boundaries of the particles, fusing the particles ...
