Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.

Magnesia acts as a flux at sintering temperatures which renders the burning slightly easier. However, a magnesia-rich kiln feed tends to ."ball" easily in the burning zone which, from an operator's viewpoint, is considered an undesirable property. Clinker, made from magnesia-rich feed must be very rapidly cooled once it has been burned ...

Role of sintering additives in the production of lime Jan 01, 1992 A production technology is proposed for lime refractories covering the preparation of highdensity lime clinker, followed by crushing, batching, adding waterproof bond, pressing the goods, and firing at 2020 KCement Plant …
The sintering temperature and time have a significant effect on the microstructure of the materials but have little effect on the crystalline phases. The fine grain morphology and stable structure are beneficial to reduce the hindrance of ion conduction. These solid electrolytes sintered at 1200 °C for 15 h shows the highest room …
The manufacturing process of the aluminate cement clinker is much similar to that of the ordinary portland cement clinker, including steps of raw material crushing & pre homogenization, raw meal pre-heating & calcination. The key to distinguish refractory cement from ordinary cement and endow it with fire resistance performance lies in the …
To improve the utilization efficiency of steel slag in cement industry, cement clinkers are prepared by simulated multi-phased clinker sintering technology with …
The sintering of cement clinker depends primarily on the mineral composition and particle size of raw materials, which are the key factors for obtaining liquid phase of clinker (Anton et al., 2000). C3S in cement clinker was commonly produced by the liquid phase reaction between C2S and CaO.
The results show that the use of wastes from the production of manganese and magnesium metals, which were added to the raw materials to make clinker pellets, can significantly reduce the firing temperature of BCSAF clinker.
Calciner technology for oxyfuel capture. Purpose is experimental investigation of suspension calcination under industrially relevant oxy-fuel conditions. Aim is to verify …
Sintering: Sintering is the process of compacting and forming a solid mass of material by heat or pressure to the point of liquefaction without actually melting it.
Multi-phased sintering technology is an innovative process that directly utilize granular steel slag to calcinate cement clinker. In this study, we synthesized a type of multi-phased clinker with high fractions of original crude granular steel slag and investigated its sintering mechanism and properties.

From the limestone mine, to crushing, blending, the raw mill, kiln and beyond, elemental analysis is a critical component to driving process control, efficiencies, and higher quality end products. ... which are then ground into a fine powder known as …
The effect of sulfuric anhydride on clinker sintering and the Portland cement activity is investigated in this paper. Using chemically pure materials have been prepared raw mixtures containing 3% CaSO 4, calculated for the formation of various mineral composition clinker. All sulfur-containing clinkers contained anhydrite and an …
The extent of the addition of these pozzolanic or inert materials to the clinker depends upon their physico-chemical characteristics and also the permitted norms by the authorities. The clinker content in the blended cement is called as the clinker factor.

Low surface tension causes porous and fine-grain clinker formation. This type of clinker has low sintering shrinkage and good grindability. However, clinker dustiness increases and it affects the thermal gradient negatively during technical processes [6]. CaF 2 addition changes the clinker constituents.
