The main solid coproducts produced during iron and crude steel production are slags (90% by mass), dust and sludge. On average, the production of one tonne of steel results in around 200 kg of coproducts for the electric arc furnace (EAF) route and 400 kg for the blast furnace basic oxygen furnace (BFBOF) route. Alongside solid coproducts, process gases from coke ovens, .

of the steel and into the slag. In modern EAF operations, especially those operating with a "hot heel" of molten steel and slag retained from the prior heat, oxygen may be blown into the bath throughout most of the heat. As a result, some of the melting and refining operations occur simultaneously. Phosphorus and sulfur occur normally in the furnace charge in higher .

Overview of slag production in modern integrated steel plant. Pit slag and clean out slag are other types of slag commonly found in steelmaking operations. They usually consist of the steel slag that falls on the floor of the plant at various stages of operation, or slag that is removed from the ladle after tapping. Because the ladle refining stage usually involves comparatively high flux ...

Steel slag, a byproduct of steel smelting, is generated during the separation of molten steel from impurities in the steel furnace. The slag is formed during smelting and is a complex compound of silies and oxides that solidify after cooling. With the production of different grades of steel, the slag properties also change significantly. Slag is usually generated between 200200 kg per ton ...

· Slag from steel production in BOF (LD) converters and electric arc furnaces can, for example, be used as material in road or railway track bed construction. In the BSSF granulation process developed by Baosteel, the liquid slag is transferred to a granulation drum where it is treated with injected water with a dwell time between three and five minutes, which significantly reduces the amount of ...

slag. In March 1963, a decision was taken to start with a fullscale engineering study to develop an iron, steel, and vanadium plant based on prior pilotplant testwork. The engineering study was done by Davy and the United Engineering Company of Sheffield1. The engineering study resulted in a rotary kiln—electric furnace (RKEF) flowsheet for the iron plant.
