Calcium carbide is converted into acetylene in a controlled reaction with water using an apparatus called a generator. Acetylene, which has the chemical formula C2H2, is an extremely useful hydrocarbon due to the energy that is locked up in the triple-bond between the carbon atoms.
Reducible oxides in the slag, primarily FeO and MnO, react with the calcium carbide to produce iron, manganese, gas and lime (CaO), as shown in the equations below. The other components of the NuFlux product then help to dissolve the CaO and facilitate the release of the CO which burns to CO2 as it contacts the air above the slag.
We are offering calcium carbide.It is used in the desulfurisation of iron (pig iron, cast iron and steel); as a fuel in steelmaking to extend the scrap ratio to liquid iron, depending on economics and also as a powerful deoxidizer at ladle treatment facilities.
Calcium carbide is a chemical compound with the chemical formula of CaC2. Its main use industrially is in the production of acetylene and calcium cyanamide. Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and coke at approximately 2000°C.
The steelmaking slag is at a temperature of from about 2500 to about 3100 degrees Fahrenheit. The ing additive contains from about 20 to about 80 weight percent of a source of elemental carbon, from about 5 to about 80 weight percent of calcium carbide, and from about 25 to about 75 weight percent of anoxide compound.
The products are customized to be used in accordance with the requirements of each process. The agents are made of calcium oxide, calcium carbide, metallic magnesium and others. Tecnosulfur also supplies the equipment required to apply these products, such as agent addition or injection systems.
Production. Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and coke at approximately 2,200 °C (3,990 °F). This is an endothermic reaction requiring 110 kilocalories (460 kJ) per mole and high temperatures to drive off the carbon monoxide. This method has not changed since its invention in 1892: CaO + 3 C → CaC 2 + CO

Steel - Steel - Electric-arc steelmaking: About one-quarter of the world's steel is produced by the electric-arc method, which uses high-current electric arcs to melt steel scrap and convert it into liquid steel of a specified chemical composition and temperature. External arc heating permits better thermal control than does the basic oxygen process, in which heating is accomplished by the ...
The equipment used for the smelting of calcium carbide is similar to that employed in electric furnaces used for other forms of ferroalloys processing, where carbon is used as a reductant. Calcium carbide is also an intermediate product in the smelting of calcium–silicon alloy. Technical grade calcium carbide is crystallized from the melt and contains ~80% CaC 2 and 10% to 15% CaO (Fig. 19.4).
Carbide lamps, or acetylene gas lamps, are simple lamps that produce and burn acetylene (C 2 H 2 ) which is created by the reaction of calcium carbide (CaC 2 ) with water (H 2 O). It was prepared by the hydrolysis of calcium carbide, a reaction discovered by Friedrich Wöhler in 1862 and still familiar to students: Arc furnaces were also used to prepare calcium carbide for use in carbide lamps.
