U.S. Pat discloses " smelting the method for titanium alloy "; this method adopts consumable arc-melting process that titanium sponge is melted in the water-cooled punching block with electric arc furnace; under protection of inert gas, form titanium alloy ingot with even composition; for the processing of titanium material is supplied. More over in the electric arc furnace scrap can be replaced up to % by unreduced iron ore (sponge iron). Electric arc furnace accounts for 51% of the total span of the three basic raw materials (scrap, pig iron and sponge iron), while open hearth furnace take about 17% and basic oxygen converters take about 9%.
United Kingdom-based Liberty House Group has reignited the furnace at its Speciality Steels operation in Rotherham, South Yorkshire, U.K. The official launch was in mid-February , with the Prince of Wales igniting the furnace. The restart of the electric arc furnace, which was mothballed by a previous owner earlier in the decade, is part of a multimillion-pound . Electric Arc Furnace Lower Capital Requirement Compared to Basic Oxygen Furnace Will Fuel the Market for Electric ARC Furnace 7 Flat Steel Market, By Type Introduction Sheets.
Each material required a different smelting condition to optimize results (9). On a commercial scale, Quebec Iron and Titanium Corp. has been processing ilmen ite in an electric arc furnace since (). In Japan, Osaka Titanium Co., Ltd.-,-has been producing a high-titania slag from ilmenites by electric furnace. Enhance custom duty on steel long products – Business. 25 Feb steel plants based on Blast Furnace, Basic Oxygen Furnace route, main S teel is closely linked with production activities in various sectors of the economy. .

Additional Physical Format: Print version: Nafziger, R.H. (Ralph H.). Electric-arc furnace processing of domestic titaniferous materials. [Washington, D.C.]: U.S. Fourteen domestic titaniferous materials were evaluated to determine those most amenable to economical processing in an electric-arc furnace and to determine optimum melting variables including (1) furnace shell composition, (2) type of reductant, (3) amount of reductant, and (4) slag conditioner.
Electric-arc furnace processing of domestic titaniferous materials Report of clerk of State land board as requested under Senate resolution no. 18 Return to Gold Country. Two domestic ilmenites and one titaniferous magnetite were prereduced by the United States Department of the Interior, Bureau of Mines, in a batch rotary kiln with coal char to assess the feasibility of this technique in improving melting operations and subsequent electric furnace processing.
All three prereduced titaniferous materials were Cited by: 5. An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about ton units used for secondary furnaces used in research laboratories and by dentists may have a capacity.
Stengel, P. Schießl, in Eco-efficient Construction and Building Materials, Electric steel production. The electric arc furnace (EAF) steel production represents about 34% of the overall European steel production (see World Steel Association, ).Concrete reinforcing steel and steel wire for the production of steel fibres are mainly derived from EAF steel.
In the electric arc furnace, steel is produced only through scrap fusion. Scraps, direct reduced iron, pig iron, and additives are melted through high. Two domestic ilmenites and one titaniferous magnetite were prereduced by the United States Department of the Interior, Bureau of Mines, in a batch rotary kiln with coal char to assess the feasibility of this technique in improving melting operations and subsequent electric furnace processing.
All three prereduced titaniferous materials were melted satisfactorily in an electric arc furnace. ri / electric-arc furnace processing of domestic titaniferous materials, pb, $ 15 ri / direct method determination of the gas content of coal: procedures and results, pb, $ 20 ri / hydrogen sulfide generation by reaction of natural gas, sulfur, and steam, pb, $ Download PDF: Sorry, we are unable to provide the full text but you may find it at the following location(s): (external link) http.
The Bureau of Mines evaluated 18 domestic titaniferous materials with widely varying compositions, mineralogy, and physical properties in electric-arc furnaces.
Techniques were devised to recover both the titanium and iron values contained in these materials so that the reliance of the United States on foreign sources of higher grade ilmenites. Prereduction and Melting of Domestic Titaniferous Materials. kiln with coal char to assess the feasibility of this technique in improving melting operations and subsequent electric furnace processing.
All three prereduced titaniferous materials were melted satisfactorily in an electric arc furnace to produce iron as a metal suitable for. TITANIFEROUS MAGNETITE DEPOSIT (Bull. 50, p. 25)[copied from deleted record =and = ] Comment Type: Deposit: Comment: GRADE 1-MASSIVE MAGNETITE-ILMENITE WITH % BY VOLUME OF SILICATES, CHIEFLY OLIVINE AND MINOR SPINEL.
TIO2% RANGES FROM % INCLUSIVE. Electric arc furnace - Wikipedia. An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc Industrial arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about ton units used for secondary steelmakingArc furnaces used in research laboratories and.
The electric arc furnace (EAF) process is the main process for recycling of ferrous scrap  and the second most important steelmaking process route. This research is conducted to determine the effect of additive variation to the Fe content and Fe recovery during sponge iron smelting process into pig iron using electric arc furnace (EAF).
Types of additives variation that used in this research are CaCl 2 and CaC 2, as well as smelting without additive as comparison. ELECTRIC ARC FURNACEELECTRIC ARC FURNACE:An Electric Arc Furnace (EAF) is a furnacethat heats charged material by means of anelectric furnaces range in size from small unitsof approximately one ton capacity (used infoundries for producing cast iron products)up to about ton units used for secondarysteelmaking 3.
An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. Induction furnace capacities range from less than one kilogram to one hundred tonnes, and are used to melt iron and steel, copper, aluminum, and precious metals.
The advantage of the induction furnace is a clean, energy-efficient and well-controllable melting process. The hot sponge iron is then melted continuously in an electric arc furnace to produce pig iron, which is finally fed to oxygen steel- making furnace for further processing.
as a secondary raw. Process (Keynote) A Study on the Characteristics of Ceramic Support Manufactured by Spent Foundry Sand/Loess Characterization of Electric Arc Furnace Slag as Construction Material Processing of Silverbearing Scrap Recycling Nonferrous Oxides in Iron and Steel Melting Reduction of Zinc Oxide with Various Additives.The type of activator used also plays an important role in the effectiveness of nickel slag-based activated binders.
Xu 81 studied the use of blended activators (mainly mixes of Na 2 SiO 3, Na 2 CO 3 or Na 2 SO 4), and found that for nickel slag with high MgO content (e.g., 15 wt.%), an increased content of Na 2 CO 3 enhanced the compressive strength.
Increasing the content of .In the United States, reserves of lower grade ilmenite and other titaniferous materials are abundant, but the country is nonetheless dependent on foreign sources for about 65 pct of the titaniferous raw material used in manufacturing TiO2, welding rod coatings, and titanium metal.
