Glassy substance formed as a by-product from the smelting of metallic ores.
A film that forms on top of molten metal as a result of impurities. Slag is composed of non-metal elements.
the leftovers from the ironmaking process, the impurities left when the iron is smelted
As related to coal, ash that is or has been in a molten state.
Waste containing impurities produced in ore-smelting.
In this work the term slag is used to describe any metamorphic vitrified mass derived from fuel ash under the influence of extreme heat. Support for the use of the term in this context can be found in its definition in the Oxford English Dictionary and in Searle's Encyclopaedia of the Ceramic Industries.
A by-product of the iron and steelmaking process comprising largely of limestone. During steelmaking, slag, which has a lower density than molten steel, floats above the molten steel and acts as a scavenger for undesirable elements in the steel. Once cooled and solidified, slag can be used in soil mixtures, road stones and cement.
A byproduct of smelting. Slag is a glassy, sand-like material containing small amounts of lead, zinc, copper and other materials.
a hard, gray, porous by-product of the steel industry.
When smelting is done, The non-metallic materials float on top of the heavier metallic constituents in the molten state, and remains in that position when it cools and hardens
the scum formed by oxidation at the surface of molten metals
a waste product which consists of impurities from the making of steel, the historically dominant economic force in the area of
The waste product of the process of smelting.
molten impurities formed by reactions during smelting
A grayish, porous aggregate left as a residue from blast furnaces and used as surfacing aggregate.
offensive term for a woman (Blasted).
Impurities in the iron ore that have been captured by limestone or other fluxes.
Residue from blast furnaces that is sometimes used for the surfacing on aggregate-surfaced built-up roof systems.
The impurities in a molten pool of iron. Flux such as limestone may be added to foster the congregation of undesired elements into a slag. Because slag is lighter than iron, it will float on top of the pool, where it can be skimmed.
In every melting process oxidic materials are created which due to their lower specific gravity float on the surface of the molten iron or steel. Undesirable elements separated from the iron oxide are passed into the slag. When solidified, slag is glass or stone-like. Steel mill slag is a valuable material: Blast furnace slags are used in the production of cement (iron portland and blast furnace cement), bricks, pumice, lime, roadbuilding materials, railway ballast and mineral wool. Finely ground phosphorus-containing converter slag is a valuable fertilizer.
A by-product, containing inert materials of the burden, produced during the melting process of blast furnace and steelmaking operations.
Smelter beneficiated titanium product (85% TiO2)
Waste product from the smelting and refining processes.
(2) -- refuse matter separated from a metal in the process of smelting (Oxford Dict.)
Waste material from the smelting process. The black, lava-like material is primarily iron and silica.
A layer of flux soot the protects the weld from oxides and other contaminants while the weld is solidifying (cooling). Slag is to be removed after cooling.
A waste substance formed during the extraction or refining of a metal from its ore. (Sometimes however, uses can be found for a slag.)
Waste from blast furnaces or from burning bituminous coal.
A man-made sediment that looks like black sand, but has a high metal content.
(1) the glassy residue from which metals have been removed at a smelter.
The waste product of a smelter.
waste material left after smelting iron
The vitreous mass of glass material separated from the fused metals in the smelting process.
Melted matter separated during the reduction of a metal from its ore.
During iron, copper and steel smelting, a fluxing agent (usually limestone) is mixed in with the heated ore to help separate the pure metal from the rock it's found in. The result is that the fluxing agent fuses with the rock, and they combine to form a waste material, called slag.
Byproduct of steelmaking, crushed and screened as aggregate.
Slag is the left over material from metalworking. It is made up of the impurities that have been separated from the metal.
A by-product of the iron industry, slag consists of mainly silica and lime with many trace elements. This may be used to improve the fertility of grassland.
The impurities in a molten pool of iron. Flux may be added to congregate the impurities into a slag. Slag is lighter than iron and will float allowing it to be skimmed.
Impurities in metal, usually removed either in the furnace or beaten out.
Porous aggregate used as built-up bituminous membrane surfacing, comprising silicates and alumino-silicates of calcium and other bases, developed with iron in a blast furnace.
A fused nonmetallic material that protects molten metal from the air and extracts certain impurities from the melt.
The fusible material formed by the chemical reaction of a flux with gangue of an ore, with ash from a fuel, or with impurities oxidized during the refining of a metal.
The layer of various oxides and impurities which form on the surface of molten metal.
a hard, air-cooled aggregate that is left as a residue from blast furnaces, which may be used as a surfacing material on certain (typically bituminous) roof membrane systems.
Waste substance produced in a forge as a result of heating iron, consisting largely of silica and iron. "Stringers" (fine threads) of slag also characterize wrought iron.
A by-product of smelting ore such as iron, lead or copper. Also overburden/dropping from welding which may burn, melt, or discolor adjacent surfaces.
a hard, air-cooled aggregate that is left as residue from blast furnaces. It is used as a surfacing aggregate and should be surface dry and free of sand, clay, or other foreign substances at the time of application.
The fused refuse separated from smelted metal or processed ore, which is used in concrete as an aggregate.
A fused nonmetallic material used to protect molten metal from the air and to extract certain impurities. The nonmetallic covering on molten metal resulting from the combination of impurities in the initial charge like ash from fuel, and any silica and clay eroded from the refactory lining. It is skimmed off prior to pouring the metal.
Slags are the by-product of smelting ore to purify metals. They can be considered to be a mixture of metal oxides; however, they can contain metal sulphides and metal atoms in the elemental form. While slags are generally used as a waste removal mechanism in metal smelting, they can also serve other purposes, such as assisting in smelt temperature control and minimizing re-oxidation of the final liquid metal product before casting.
