Processing produces slag

Mar 08, 2016 There are several different types of steel slag produced during the steel-making process. These different types are referred to as furnace or tap slag, raker slag, synthetic or ladle slags, and pit or cleanout slag. Figure 18-1 presents a diagram of the general flow and production of different slags in a modern steel plant

When molten iron (referred to as “hot metal”) from the blast furnace is to be converted into steel, the main tasks are the removal of carbon, silicon and phosphorus. The LD (Linz-Donawitz) process is by far the most widely used, and takes its name from the towns where it was developed

    Sep 07, 2012 Sep 07, 2012 The most common process for granulating blast furnace slag involves the use of high water volume, high pressure water jets in direct contact with the molten blast furnace slag at a ratio of approximately 10 to 1 by mass. The molten blast furnace slag is quenched almost immediately to form a material generally smaller than a #4 sieve

    Slag: From By-product to Valuable Construction Material

    Slag is a by-product of the metallurgical smelting process. Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process in order for the desirable elements to stay in the melt while the others are removed
