  • 5.1 Introduction blast furnace slag and steel furnace

    Blast furnace slag (BFS) and steel furnace slag (SFS) have a long history of use as industrial by-products, going back almost 100 years in the United States and 150 years in Europe. The content of trace elements, such as manganese, copper, zinc, boron or cobalt, satisfies both plant and animal demands [8, 9]. Iron and steelmaking slag Lead and Zinc Smelting International Finance Corporation,blast furnaces, rotary furnaces, or reverberatory furnaces. A reverberatory furnace is more suit-able for processing fine particles and may be op-erated in conjunction with a blast furnace. Blast furnaces produce hard lead from charges containing siliceous slag from previous runs (about 4.5% of the charge), scrap iron (about

  • The Blast Furnace

    The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.EFFECT OF ALKALINE ELEMENTS ON COKE STRUCTURE UNDER BLAST ,Presence of alkaline elements such as sodium and potassium are highly detrimental for blast furnace operations. Even a trace amount of alkali affects the performance of raw materials considerably.

It consists mainly of Fe, O, and C and contains major amounts of Si, Al, and Mg. Besides these elements, the sludge also contains trace metals such as Cd, Zn, and Pb. Reliable information about the total contents and distribution of the elements present in blast furnace sludge is of importance for


    Function of blast furnace cooling system is to cool the furnace shell and prevent from cooling of blast furnaces by means of stave coolers. Modern blast furnaces are properties over the complete cooling element. In those regions of the blast furnace whichBlast furnace , metallurgy ,,Basically, the blast furnace is a countercurrent heat and oxygen exchanger in which rising combustion gas loses most of its heat on the way up, leaving the furnace at a temperature of about 200° C (390° F), while descending iron oxides are wholly

The air is blown through the blast furnace from the bottom upwards and carries over coke and iron ore particles into Extraction of Iron , Metallurgy , Blast Furnace and Reactions,A Blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.

  • Copper staves for blast furnaces KME

    blast furnaces are readily available and conse quently achieve a high level of productivity. Copper staves were first utilised in blast furnaces in the late 1970s as the best high heat-load wall-cooling element.

  • Chemistry of the Ironmaking by Blast Furnace Process

    These elements are used to produce a slag of the desired composition. The factors determining the optimum composition are physical, chemical and commercial and the final choice is usually that of a compromise between the three. Slag must be fluid to run freely from the blast furnace and also it should have the capacity to absorb sulphur.Slags, ferrous metal, blast furnace Registration Dossier ,EC number 266-002-0 , CAS number 65996-69-2 The fused substance formed by the action of a flux upon the gangue of the iron-bearing materials charged to a blast furnace and upon the oxidized impurities in the iron produced. Depending upon the particular blast furnace operation, the slag is composed primarily of sulfur and oxides of aluminum, calcium, magnesium, and silicon.
