The production of steel in an EAF is a batch process. Cycles, or heats , range from about 1-12 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag
Steel - Steel - Electric-arc steelmaking About one-quarter of the worlds steel is produced by the electric-arc method, which uses high-current electric arcs to melt steel scrap and convert it into liquid steel of a specified chemical composition and temperature. External arc heating permits better thermal control than does the basic oxygen process, in which heating is accomplished
Basic Oxygen Furnace BOF steel making or Basic Oxygen Furnace Steelmaking BOS or Linz-Donawitz-Verfahren steelmaking or the oxygen converter process is a method in which both molten pig iron and steel scrap are converted into steel with the oxidizing action of oxygen blown into the melt under a basic slag.
Nov 14, 2018 BOF, CaO, EAF, MgO, Slag basicity, slag processing, Steelmaking slag, Properties and Uses of Steelmaking Slag. Steelmaking slag is an integral part of the steelmaking process. It is produced during the separation of the liquid steel from impurities in steelmaking furnace and is a non-metallic by-product of steelmaking process.

Steel slag recycling is a serious problem in China. The volume of steel slag is growing rapidly because the output of steel is steadily increasing however, slags utilization remains relatively low. The utilization rate in China is only 29.5, whereas the utilization rate of steel slag in industrial countries is more than 85.
Steel slag introduction The steel slag crushing production line is a production line for recycling and recycling of steel slag and other resources based on the characteristics of steel slag hardness and rationally equipped equipment.Dewo provides customers with technical services and design of 30-800tph steel slag processing line
The samples of slag used in this experiment were not carbonated into blocks, but of irregular shapes and sizes and were collected directly from the steel plant after being cooled. The coral species were fixed to the slag using a small amount of epoxy and seawater cement.Flow chart of steel slag crushing production plant Recycling... Read More Read More
1. Introduction. During the steelmaking process, various slags are produced as by-products Shen and Forssberg, 2003.The first stage of steel production is blast furnace steelmaking, in which raw iron ore is converted into pig iron, which contains various amounts of carbon, silicon, manganese, sulfur and phosphorus.Apart from the recycling of steel slag into the blast
May 05, 2013 Fig 4 Schematic diagram of a slag granulation plant. Granulation section Here, the liquid BF slag is water quenched and solidified into small particles, eliminating the need for heavy crushing equipment. The liquid slag flows by runners from the BF to the granulation unit. From the runner, the liquid slag stream at around 1,500 deg C is poured into a high velocity

In this chapter, two main slag practices are ...
Slags are nonmetallic byproducts of many metallurgical operations and consist primarily of calcium, magnesium, and aluminum silicates in various combinations. Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the
The slag granulation plant comprises three sections for granulation, dewatering and storage. In the granulation section, the liquid slag is quenched by pouring onto it an excess water stream. The evaporated water will be condensed in a condensing

The use of EAFs has expanded and now accounts for nearly 23 of steel production in the United States. The EAF is different from the blast furnace as it produces steel by using an electrical current to melt scrap steel andor direct reduced iron. The EAF uses scrap steel and electricity to produce molten steel.
