Converter slag In the same way as aircooled blast furnace slag, converter slag is cooled slowly by natural cooling and water spray in a cooling yard. It is then processed and used for various iron and steel slag (converter) applications. Approximately 110 kg of slag is generated for each ton of converter steel. Electric arc furnace slag

When the removal of the matte or slag is complete, the hole is normally plugged with clay, which is removed when the furnace is ready to be tapped again. Reverberatory furnaces were often used to treat molten converter slag to recover contained copper. This would be poured into the furnaces from ladles carried by cranes.
Equipment To Treat Converter Slag Converting (metallurgy) Wikipedia. Converting is a type of metallurgical smelting that includes several processes; the most commercially important form is the treatment of molten metal sulfides to produce crude metal and slag.
Ensure high energy efficiency with the Outotec Flash Converting Process. Our process can operate autogenously without using additional fossil fuels, even with high matte grades. Optionally the flash converter slag can be recirculated to the smelting furnace for heat balance purposes, removing the need for additional slag treatment units.
High Temperatures Technologies Corp. Canada presents the products based on plasma technology for different fields such as waste treatment, nanomaterials production and others. High Temperature Technologies Corp. offer ecologically pure technology which purpose is a full decomposition of the treated waste without leaving harmful toxic waste and reception of useful products.
However, the current reclaiming ratio of waste steel in China is still low due to lack of advanced slag treatment equipment and technology. Utilization as sinter material Steel slag with CaO content above 50% can be used as sinter ore fluxing agent, partially replacing the commercial lime.
Steelmaking slag includes the following: slag produced in the hotmetal pretreatment processes (desiliconization, dephosphorization, desulfurization, etc.), slag flowing out from the converter into the molten steel ladle, and slag formed during the secondary refining treatment (this slag is sometimes called "secondary refining slag" or
Oct 05, 1976· Treatment of converter slag . United States Patent . Abstract: A process for the production of copper from raw materials containing sulphur, zinc and more than % Ni calculated on the copper content. The material is melted to matte and the matte converted to white metal, whereafter the white metal is converted to copper and the zinc ...
Primary Copper Smelting General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total ... some of the impurities in the charge oxidize with the fluxes to form a slag on top of the molten bath, ... also treat converter gas effluent. Some multiple hearth and all fluidized bed roasters use sulfuric acid
test that the longer the steam aging treatment time, the smaller is the amount of the expansion of a steelmaking slag and that the expansion by hydration reaction converges to approximately one expansion ratio at the aging treatment time of 72 hours (Fig. ). However, even when aging treatment processing for 72 hours is performed,
Steel Steel Openhearth steelmaking: Though it has been almost completely replaced by BOF and EAF steelmaking in many highly industrialized countries, the open hearth nevertheless accounts for about onesixth of all steel produced worldwide. The openhearth furnace (OHF) uses the heat of combustion of gaseous or liquid fuels to convert a charge of scrap and liquid blastfurnace iron to ...
EXCEPTIONAL CASTING CAPABILITIES BROUGHT TO LIGHT. We are a leading manufacturer of high performance steel millrelated castings, including the world''s finest slag pots, coiler drums for steckel mill applications, mechanical mill parts and metalworking press castings.
Plasma gasification is an extreme thermal process using plasma which converts organic matter into a syngas (synthesis gas) which is primarily made up of hydrogen and carbon plasma torch powered by an electric arc is used to ionize gas and catalyze organic matter into syngas, with slag remaining as a byproduct. It is used commercially as a form of waste treatment and has been tested ...
furnace is charged to converters where the molten material is oxidized in the presence of air to remove the iron and sulfur impurities (as converter slag) and to form blister copper. Blister copper is further refined as either firerefined copper or anode copper (% pure copper), which is used in subsequent electrolytic refining.
ISASMELT technology has been applied to lead, copper, and nickel smelting, and by 2013 fifteen plants were in operation in ten countries, with another five in various stages of development. The installed capacity of the operating plants in 2013 was over 8 million tonnes per year (t/y) of feed materials, with additional capacity to come on line in 2013 and 2014.
Converting is a type of metallurgical smelting that includes several processes; the most commercially important form is the treatment of molten metal sulfides to produce crude metal and slag, as in the case of copper and nickel converting. A nowuncommon form is batch treatment of pig iron to produce steel by the Bessemer process. The vessel used was called the Bessemer converter.
Table 1 shows the characteristics of a converter slag. It is suitable for use as a metal adsorber in industrial wastewater treatment, .The slag is mainly composed of iron oxide (Fe 3 O 4 — magnetite), and has also, low particle size and high surface area, .
and treatment method using a rotary cooler as the main equipment. Studies on slag treatment process Two types of slag stem from iron and steelmaking processes: blast furnace and steelmaking slags. Various methods for granulating blast furnace slag using water were developed since the 1970s, and its use as blast furnace cement rapidly ...
melting furnaces, pressure pour furnaces and magnesium treatment vessels with minimal to no adverse effects on refractory linings. Slag Formation: The formation of slag in the melting of ferrous metals in the foundry is inevitable. The composition of slag varies with the type of melting process used and the type of iron or steel being melted.
maintains that focus because most lime for soil treatment is used in highway construction. However, the use of lime for soil drying, temporary modification, and permanent stabilization is not limited to highway constructionsee Chapter V for more information.
processing for their recovery. Slag can be used as construction material after nickel recovery as appropriate ( return of converter slag to the furnace). Sanitary sewage effluents require treatment in a separate facility or discharged to a municipal sewer. Modern plants using good industrial practices are able to achieve the following in
