basic oxygen furnace powder

Making Metal Powder - MPIF

In solid-state reduction, selected ore is crushed, typically mixed with carbon, and passed through a continuous furnace. In the furnace, a reaction takes place, reducing the carbon and oxygen from the powder, that leaves a cake of sponge metal which is then crushed, separated from all non-metallic material, and sieved to produce powder.

Abstract Optical microscopy, total oxygen measurements and slime tests have been conducted to quantify the size distribution and amount of inclusions at various processing steps during basic oxygen furnace (BOF) based steel production at Baosteel. The effects

oxygen furnace --cnki

The steels investigated were made through the basic oxygen furnace (BOF)-continuous casting route and rolled in the rail and structural mill into 90 kg/mm2 ultimate tensile strength (UTS) grade rails. The anticipated foaming in basic oxygen furnace (BOF), electric arc furnace (EAF), and bath-smelting processes was estimated using the parameter Σ for various operating conditions and slag

Electric Arc Furnace Runner and Method of Forming an …

31/7/2008· The refractory material can be applied to a refractory structure such as an electric arc furnace runner, a tundish, or an electric arc furnace tap hole or a basic oxygen furnace tap hole. The composition applied to the refractory structure comprises 85 to 95 wt. percent of an alumina source, and 5 to 15 wt. percent aqueous sodium silie.

Nitrogen Control in Electric Arc Furnace Steelmaking by …

In the electric arc furnace (EAF), and the basic oxygen furnace (BOF) for producing steel, the major off gas is carbon monoxide (CO). If the CO can be cousted to CO{sub 2}, and the energy transferred to the metal, this reaction will reduce the energy consumed in the EAF and allow for more scrap melting in the BOF which would significantly lower the energy required to produce steel.

Adsorption of Al, Cr and Zn from a wastewater effluent …

5/11/2018· Adsorption of Cr, Al and Zn from a powder coating aluminium process wastewater was achieved using Basic oxygen furnace slag (BOFS) as an adsorbent. Batch adsorption studies were used to investigate the effects of solid-loading effect, temperature and contact

Characterization of basic oxygen furnace slag and …

Basic oxygen furnace slag and granite waste compositions have been published previously (Arrivabene et al., 2012). Table 2 summarize the results. It is noted that BOFS is composed mainly for CaO (46.0%) and SiO 2 (10%), with binary basicity of 4.6.

Modifiion of steel slag powder by mineral admixture …

Modifiion of steel slag powder by mineral admixture and chemical activators to utilize in cement-based materials was studied in this work. The results showed that for cement pastes with steel slag alone, the normal consistency water requirement and compressive strength were decreased significantly. Both of the initial setting time and final setting time were also retarded than that of the
