Dolomite Its Processing And Application In Iron And

Jun 28, 2017 During the production of iron by blast furnace BF route, dolomite is added either in the process of sintering or as a direct feed in the blast furnace. Raw dolomite is normally used for this addition. Dolomite addition is made during ironmaking for obtaining desired percentage of MgO in the BF slag. Addition of dolomite through sinter is more preferred route since CO2 of dolomite is driven out

Blast furnace slag. Blast furnace slag is formed during the production of hot metal by thermo-chemical reduction in a blast furnace. During this continuous process, iron ore or pellets as well as fluxes lime stone andor dolomite are heated under reducing conditions in the presence of heated air. Coke and other reducing agents e.g. injected coal are combusted to produce carbon monoxide which reduces

Ground Granulated Blastfurnace Slag Wikipedia

Silicate and aluminate impurities from the ore and coke are combined in the blast furnace with a flux which lowers the viscosity of the slag. In the case of pig iron production the flux consists mostly of a mixture of limestone and forsterite or in some cases dolomite. In the blast furnace the slag floats on top of the iron and is decanted for separation. Slow cooling of slag melts results in an unreactive

Sustainability For Blast Furnace Slag Use Of Some

Jul 03, 2015 Blast furnace slag is a by-product from blast furnaces which is used to produce iron. Blast furnace slag has been used extensively as a successful replacement material for Portland cement in concrete materials to improve durability, produce high strength and high performance concrete, and brings environmental and economic benefits together, such as resource conservation and energy

The Use Of Blast Furnace Slags In Road Pavement

The static and dynamic characteristics of blast furnace slags obtained from the Port Kembla Works of Australian Iron and Steel Pty Limited were studied to determine their suitability for use in road pavements. Since road construction materials are frequently characterised by use of resilient moduli, the compressive strengths and resilient moduli were determined for road base of the following slags 1 air cooled crushed blast furnace slag 2 mixes of air cooled blast furnace slag ...

Influence Of Blastfurnace Slag On Behaviour Of Dolomite

Sep 30, 2015 As a result of experimental studies, dolomite used instead of cement caused up to 1.75 mm expansion. The results are in accordance with the values indicated in the standards. As a conclusion, it is possible to use blast-furnace slag in balancing the expansion properties of dolomite.

Limestone And Dolomite And Their Use In Iron And Steel

May 08, 2013 In ironmaking, limestone and dolomite are used in the production of sinter, pellets, and directly in blast furnace as fluxing materials. In case of steelmaking limestone and dolomite are used as lime or calcined dolomite both in the primary steelmaking basic oxygen furnace, electric arc furnace, and in the secondary steel making processes.

Is Slag Good For Driveways

Apr 22, 2020 Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux either limestone or dolomite are melted together in a blast furnace. During the period of cooling and hardening from its molten state, BF slag can be cooled in several ways to form any of several types of BF slag

125 Iron And Steel Production

12.5.2.2 Blast Furnace - The primary source of blast furnace emissions is the casting operation. Particulate emissions are generated when the molten iron and slag contact air above their surface. Casting emissions also are generated by drilling and plugging the taphole. The occasional use of an oxygen lance to open a

Insulation Materials Rock And Slag Wool Insulation A

Jul 01, 2008 Slag wool insulation is composed principally of fibers manufactured by melting the primary component, blast furnace slag, with a combination of some natural rock, with or without binders, depending on the product. Typically, slag wool insulation uses approximately 70 percent blast furnace slag, with the remaining volume of raw materials being ...

How Is Slag Removed From Molten Iron Quora

Slag is less dense than iron so it floats on the surface. In a blast furnace the hot metal comes out of the tap hole in the side of the furnace and goes down a trough or runner. A refractory coated skimming blade skims the surface of the hot metal...
