In the present work, a modified thermal analysis technique was used for studying the heat effect of slag foaming with carbonates addition. Experiments were conducted by sinking limestone and dolomite pieces of defined shapes (together with iron sinkers) in molten slag and monitoring the temperature ...
dolomite coarse aggregate, this study investigates the potential of using FRAP sources containing steel furnace slag (SFS) aggregates. Because it is an industrial by-product, SFS aggregates have seen relatively few applications in concrete pavements and other bound applications, primarily because of the potential expansive nature of SFS.

The slag foaming process is currently applied in the steel production due to its greater benefits, i.e., reduction of energy losses, enhancement of the refractory service life and productivity, etc. Lime/dolomite, oxygen and carbon are usually added during an electric arc furnace (EAF) operation to adjust the liquid basicity and saturation and also provide suitable conditions for foam generation.
Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in …
The addition of dolomitic lime (to around 8% or less commonly 14% MgO) also reduces the tendency of the slag to dissolve the magnesia refractory lining of the vessel. The addition of the correct levels of lime and dolomitic lime are now considered essential at most modern basic oxygen steelmaking plants.
Air-slag-metal resistance was measured on dolomite- carbon samples in the temperature range of 2,960° to 3,000° F using an AISI 1020 (low carbon) grade of steel and an aggressive acid slag (table 5).

added lime and dolomite lime and iron oxide so it is a form of slag. How much silicon is oxidized? this is very important because amount of silicon oxide is related to heat generated by this reaction and temperature inside this vessel.
Calcined Dolomite Activated Slag Paste. The hydration properties of calcined dolomite activated slag were investigated by Gu et al. in a related paper. The results indicated that relatively higher quantities of CaO and MgO in D1000 led to a higher hydration degree of slag with higher contents of C-S-H and hydrotalcite-like phases than D800 did.
Abstract In the present study, the dissolution mechanism and rate of lime, limestone and dolomite in converter slag was studied. Lime dissolution in stagnant slag was studied first and dissolution

In addition to those before me, having spent 33 years in concrete technology, I have no doubt that I can answer another aspect of the life of steel mill slag. Ground granulated blast furnace slag (GGBFS, or just "slag") is a very useful supplementary cementitious material.
In addition to environmental benefits, the use of recycled aggregates in pavement concrete lowers the overall construction cost by eliminating the expenditure associated with mining and transporting good quality natural aggregates, and with disposal of waste material (1). Blast furnace slag is a by-product generated during melting of iron ore.
Burnt Dolomite Bricks Components. Dolomite brick is a kind of refractory products that is made from calcined dolomite sand. Generally speaking, the content of the calcium oxide is more than 40%, and that of magnesium oxide is 35% above. In addition, there …
In this study, influence of blast-furnace slag (BFS) on expansion properties of dolomite was explored. Portland Cement (CEM I 42.5R) was replaced with dolomite up to 40% and blast-furnace slag …
In industry, dolomite is an important source for magnesium and calcium metals, and is used as a flux for metallurgy. A flux is a material that melts easily and can be used to remove impurities from metal ores or to make the slag produced by metal ore smelting more fluid so it can be disposed of more easily.
