قیمت را بگیریدThe furnace. The electric-arc furnace (EAF) is a squat, cylindrical vessel made of heavy steel plates.It has a dish-shaped refractory hearth and three vertical electrodes that reach down through a dome-shaped, removable roof (see figure).The shell diameter of a 10-, 100-, and 300-ton EAF is approximately 2.5, 6, and 9 metres.
قیمت را بگیریدThere are 331 electric furnace slag suppliers, mainly located in Asia. The top supplying countries are China, India, and United States, which supply 96%, 1%, and 1% of electric furnace slag respectively. Electric furnace slag products are most popular in Mid East, Southeast Asia, and South Asia.
قیمت را بگیریدELECTRIC ARC FURNACE SLAG Electric arc furnace slag (EAFS) is a byproduct that outcomes from the 3rd phase of the metallurgical process, fine grained (90% grain size less than 2mm), 98% amorphous (due to sudden cooling into water), consisted mainly of SiO2 (about 40%), FeO (about 35%) and other oxides (of Al, Mg, Cr, and Ca ).
قیمت را بگیریدUtilization of electric arc furnace slag (EAF slag) as blending material for Portland cement has been examined. This was done via the investigation of the hydration characteristic of EAF slag – Portland cement blended mixtures. Various ratios of EAF slag were used namely; 5, 10 and 20 wt% of solid mix.
Steel Furnace Slag Steel Furnace Slag is produced in a (BOF) Basic Oxygen Furnace or an (EAF) Electric Arc Furnace. Hot iron (BOF) and/or scrap metal (EAF) are the primary metals to make steel in each process. Lime is injected to act as a fluxing agent.
قیمت را بگیریدground granulated blast furnace (GGBF) slag was reported as early as 1774. GGBF slag has been used in concrete in Japan and Western Europe since the 1940s. Concrete containing slag is estimated to comprise approximately 20 percent of the hydraulic cement produced in Europe. Blast furnace slag is used predominately as base and concrete aggregate ...
