In addition to liquid hot metal, the blast furnace also produces slag. This blast furnace slag floats on top of the liquid hot metal and contains the fluxes and the gangue of the iron ore. The slag is tapped, granulated by means of a high-pressure water spray, de-watered in rotating drum filters and transported for use in the construction industry.
Granulated blast furnace slag High-energy ball milling Cement paste Compressive strength Structural characterisation 1. Introduction In extractive metallurgy, blast furnaceslag(BFS) formsasa result of melting of iron oxides (raw ore, pellet, sinter) in blast furnace. Besides its role during iron smelting for assisting impurity removal from the
Pelletized blast furnace slag. Smooth texture and rounded shape when ground, keeping the porosity and water absorption much lower than the air-cooled or foamed slags. Granulated blast furnace slag. Glassy granular material and varies in structure depending on the chemical composition and method of production.
The terms blast furnace slag (BFS) and granulated blast furnace slag, as well as LD slag and electric furnace slag are used for finer distinctions. With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t …
quenched to form slag granulate – a glassy mineral product – and then the granulate is milled to cement-like fineness in a 'cement' mill – creating Ground Granulated Blast Furnace Slag (GGBFS). GGBFS has a long history of use as a cementitious material in a number of countries, but in Australia its
Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. Blast-furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated at a temperature of about 1,500°C. When iron-ore, coke and limestone melt in the blast furnace, two products are produced—molten iron, and molten slag.
Accordingly, the present invention provides an improved process for the production of Portland slag cement using granulated blast furnace slag, which comprises: (viii) forming of cement clinker by known process, (ix) ball-milling of cement clinker for a period ranging between 30-60 minutes in dry condition, (x) reducing size of granulated blast furnace slag by any process to …
The main application of the blast furnace is to smelt the iron from its ore and The pig iron formed during the process is used for the production of various grades of steel. The slag formed in the blast furnace can be used as raw material for the production of cement. More Resources:
