Pig iron known to steelmakers as hot metal is produced in the blast furnaces from iron ore coke coal and additives This is the task of ROGESA a joint subsidiary of Dillinger and Saarstahl ROGESA operates two blast furnaces of 11 2 and 12 0 m hearth diameter respectively Upstream of the blast furnaces are two sinter plants Coke is supplied predominantly from the Zentralkokerei Saar

Merchant blast furnaces and by-product or beehive coke ovens are also included in this industry Snapshot SIC Code 3312 - Steel Works Blast Furnaces (including Coke Ovens) and Rolling Mills is a final level code of the "Manufacturing" Division There are 1 388 companies classified in this industry in the USA with an estimated employment

Pig vs Scrap Iron When it comes to quality soil pipe and fittings scrap beats pig every time March 7 2017 No Comments There is a notion being propagated by importers of Chinese-made cast iron soil pipe and fittings that the use of "" pig iron as a raw material for manufacturing these products is preferable to recycling scrap iron into new products While pig iron may be the

Blast furnaces account for up to 40 percent of the total amount of oxygen used in a typical integrated steel mill Oxygen is injected into these furnaces through spargers--devices used to spray gas into a system--to enrich the air This process increases the productivity of the furnace It also serves to lower coke consumption by facilitating the addition of powdered coal and natural gas to

Why is scrap used in a blast furnace?

The Old Metallurgical Engineer and Steelmaker says Ferrous scrap (steel or iron scrap) is NOT used in a blast furnace It has been tried shredded scrap has been added to the iron ore burden of a blast furnace but no improvement in "hot metal" (

Scrap We source and supply steel scrap of various specifications to steel manufacturers addressing key needs of the industry namely consistent quality and on-time delivery Recycled scrap metal is used in the manufacturing of metals as it is both commercially and environmentally beneficial

Found in every corner of the planet steel has come to be one of our most used materials for building a sturdy product Two types of furnaces that create steel are the basic oxygen furnace and the electric arc furnace each of which have their own set of pros and cons

Blast furnaces are used to recycle slag dross and residues from other processes Blast furnaces require metallurgical coke produce large volumes of gas that must be filtered require a special charge require afterburners to burn carbon monoxide contained in off-gases and produce slag and matte that in some cases may be considered hazardous materials Blast furnaces produce a bullion

Appendix A Use of Ferrous Scrap the increased use of electric arc furnaces for usually use ferrous scrap but which could also iron the increased use of continuous casting is an effective way to increase the use of purchased prompt industrial 1) and obsolete scrap This new scrap consumption is based on increased yield and the maintenance of the original level of hot metal production (existing

Both blast and electric arc furnaces are used in industrial settings to heat and mold metal A blast furnace is used to make steel from liquid iron while an electric arc furnace is used to make steel from scrap material Electric arc furnaces use two different types of electrical currents to create heat Blast furnaces force air into the bottom of the furnace into a heated stove area The

It is primarily used is in electric arc furnaces (EAF) but can also be used by blast furnaces and other iron and steelmaking applications Both iron oxide pellets and lump ores can be used in the production of DRI DRI is a valuable supplement to scrap in the EAF process helping dilute the impurities and residual metals that come along with

01 05 2020A scrap size of ~10 mm which is a relatively small size was said to be favoured to prevent damage to conveyors but scrap up to ~100 mm was manageable We also found that ironmakers with smaller BFs (i e 1 000 m3 in size) were on average charging higher amounts of scrap than larger BFs which likely related to more conservative operating practices in larger BFs

reducing iron oxide to metallic iron in blast furnaces scrap is the major input to electric steelmaking furnaces The adequacy of fu-ture supplies of both is uncertain A shortage of cokemaking facilities not of metallurgical coal from which to make coke is the problem Coke used by the integrated steel companies as a feedstock in ironmaking is mostly produced in byproduct ovens from high

Even in iron ore-consuming blast furnaces scrap remains an important additive and can make up 10-20% of the total raw material mix As a proportion of costs movements in scrap prices can have a major impact on a steel mill's profitability Steel output by production method 2014 Understanding steel scrap and the new LME ferrous contracts

DRI scrap and hot metal from blast furnaces or from Corex units are used in various proportions for steelmaking The theme of the fourth annual conference organised by the Kolkata based publication Steel Tech was Optimisation of Iron and Steelmaking Operations The event was held in Kolkata's oldest major hotel the Oberoi Grand Greater international participation was sought through a
