Sintering characteristics of fluxes and their structure optimization .

High reactive quicklime should be used as much as possible in the sintering mixture. It reached better sintering results while quicklime was used instead of line and its appropriate proportion in the sintering mixture was around 4wt%. On the premise of ensuring the MgO content, the dolomite amount should be.

Coke optimization with machine learning method in sinter plant .

Abstract: Sintered product which is the largest entry of blast furnace is produced in the sinter plant which is one of the main unit of integrated iron and steel factories. Line and dolomite are added to fine ore in the sinter plant, and this mixture is sent to the blast furnace after smelted with coke fuel. The use of coke.

Sintering dolomite and line as a function of their industrial .

During the calcination of pure, difficult-to-sinter varieties of line and dolomite their preliminary industrial processing, consisting in a calcination firing, and subsequent slaking of the material, allows the production of sintered dolomite and line clinker with an apparent density respectively of 3.28–3.31 and 2.96.

Sinter plant - Wikipedia

Main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux (lime stone) fines. In addition to base mix, coke fines, flux fines, sinter fines, iron dust (collected from plant de-dusting system & ESP) and plant waste are mixed in proportion (by weight) in a rotary drum, often called mixing and.

Global effects of closing down sinter plant at Ruukki . - DiVA portal

CO2 emissions will be formed from combustion of carbon in oil and calcination of line. The iron ore pellets produced for Ruukki are olivine-fluxed with Fe content of 67%. 2.3 Steel production system. Processes directly influenced by the shift from sinter based to pellet based hot metal production is the blast furnace,.

Iron and Steel | Lhoist - Minerals and lime producer

Fine-crushed line is used as a flux in iron ore sintering. It adjusts the overall chemistry of the iron burden and plays a vital role in the formation of slag in the blast furnace process. Lime-based binders - sometimes including special clays - increase sinter plant productivity. Higher percentages of ultra-fine ore can also be.

Control of the grain size distribution of the raw material mixture in the .

In the majority of production processes, the particle size distributions of the raw materials influence the properties of the product. This also pertains to iron sinter, which is constituted of a mixture of raw materials (iron ore, coke breeze, line, lime, dolomite, return fines) all of which have various size distributions. Although.
