Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace. When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag. During the period of cooling ...
In masonry, the most commonly used materials are concrete blocks or burnt clay brick. Owing to energy costs, there is a need to explore alternative raw materials and energy-efficient technologies for making building materials. This paper deals with the incorporation of blast furnace granulated slag in sand–lime materials as a replacement for ...
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper.

Air-cooled Blast Furnace SlagThe simplest treatment of the liquid slag is to lead it into a slag pit where layers build up until the pit is full. When it has fully solidified and then cooled somewhat, the slag (commonly known as air-cooled blast furnace slag or ACBFS) is excavated and transported away for further treatment (such as magnetic removal of any iron, or crushing and screening). Slag ...
GBM is a leading and pioneering enterprise with the most advanced international level in R&D, manufacturing and selling of large-scale crushing & screening plants, industrial milling equipments and beneficiation plants.
1. Introduction. Currently, blast furnace slag, which is emitted at temperatures ranging from 1450 to 1650 °C, is treated by water quenching, and the heat of the slag is not recovered, despite the large heat content of molten slag.
Abstract. Blast furnace water-cooled slag (BFWS) has been solidified using a hydrothermal processing method, in which the BFWS could be solidified in an autoclave under saturated steam pressure (1.56 MPa) at 200 °C for 12 h by the additions of quartz or coal flyash.
Although blast furnace slag contains a small component of elemental sulfur (1 to 2 percent), the leachate tends to be slightly alkaline and does not present a corrosion risk to steel in pilings (10) or to steel embedded in concrete made with blast furnace slag cement or aggregates.

In a blast furnace, the flow phenomenon of the slag, as dictated by its viscosity, greatly influences the heat transfer, mass transfer and chemical reactions between the slag and the metal.
