At Carbide Industries, calcium carbide production in different sizes (grades) is all we do. Generally speaking, the different grades of carbide that we make correspond to different reactivities of the carbide. For example, we produce fast-acting carbide powder that is injected into molten iron to combine with and remove sulfur. We also supply carbide in a slower-reacting nut size to add to the stream of molten metal when the steelmaking furnace is tapped. The carbide reduces oxides and returns iron and metal alloys to the steel that would otherwise be trapped in the slag, but does not react so fast that the steel overflows its ladle.

The best way to choose which grade you need is to contact us. Our industry experts have decades of experience specifying carbide grades for different applications and optimizing processes in many industries.

Calcium carbide is a powerful and effective chemical reducing agent, and can also be used as a source of energy. Nowhere is this more evident than in the field of metallurgy, where it is used in several ways to reduce costs.

In modern steelmaking operations, the need for lower sulfur steels demanded by modern continuous casting operations and specialty applications has increased calcium carbide's appeal as a hot metal desulfurizer or as a modifier to the slag to increase desulfurization efficiency.

In addition, the reaction of carbide with oxides produces a large amount of heat that is highly retained in the process. This has efficiency implications for ladle metallurgy, but moreover carbide provides major cost savings as a source of energy and productivity improvement in the steelmaking furnace.

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. This energy is then released and utilized in different ways by our customers for a variety of industrial purposes.

An acetylene cylinder for cutting and welding purposes is perhaps the most recognizable use, but many important chemicals are derived from acetylene.

When carbide is reacted with water to produce acetylene, it produces calcium hydroxide, itself a useful chemical. Having a pH of 12.4 and a ready reactivity with sulfur, it is widely used for acid neutralization, pH modification of soil, and for the cleaning of sulfur emissions from industrial processes and power generators.

In modern steelmaking operations, the need for lower sulfur steels demanded by modern continuous casting operations and specialty applications has increased calcium carbide's appeal as a hot metal desulfurizer.

As late as , most blast furnace iron was desulfurized in the torpedo car as shown above. In the integrated steel mill, this practice has now been largely replaced by the use magnesium to remove an initial amount of sulfur in the transfer ladle, and the use of carbide as a steel ladle deoxidizer and slag conditioner to obtain the final sulfur specification.

In ductile iron foundries, liquid iron must be desulfurized before specialized inoculation treatments can be employed. This desulfurization is frequently performed by feeding granular forms of calcium carbide onto the surface of the liquid iron, which is contained in specially designed mixing units.

Purity and particle size are the key parameters for optimum effectiveness in these applications. Particle sizing is carefully selected to provide maximum contact with carbide particles without incurring excessive dust losses.

Carbide Industries manufactures three standard sized products for ductile iron desulfurization, generally within the range of 8 to 80 US-mesh (2.5 to 0.2 mm). In addition, two patented specialty products are available to meet specific customer requirements. These specialized products are formulated to help eliminate the retention of unreacted carbide in the resulting desulfurization slags and also to minimize slag odor.

For subsurface injection, a powdered carbide is manufactured by ball milling selected sizes of carbide to less than 140 US-mesh (<105 microns). The milled carbide can then be custom blended with a wide range of other powder additives, such as lime, limestone, and fluorspar to meet customer specified formulations. The milled carbide is treated with special additives to significantly improve flow characteristics.

Because of their reactivity, calcium carbide powders are manufactured, mixed, loaded, and transported in either 20 ton pressure differential trailers or 90 ton railcars, under an inert nitrogen atmosphere.

Carbide is an essential tool for the removal of unwanted iron oxide from furnace slag that is carried into the ladle during tapping. When added to the liquid metal stream, or to the ladle after tapping, a coarser grained carbide reacts with the oxides and recovers iron and expensive alloys that otherwise would have been lost. Furthermore, left untreated, these oxides can interfere with the downstream steel refining operation by inhibiting desulfurization, oxidizing ("fading") alloy additions, and attacking refractories.

Although aluminum, ferrosilicon, silicon carbide, and even coke have also been used for this purpose, calcium carbide has proven to be more economical, more efficient, and more reproducible in its effects. This is due to the fact that unlike the other materials, calcium carbide produces CO gas which uniformly distributes and mixes the carbide while foaming the slag; does not require a balancing lime addition as do silicon-based additives (in fact every pound of carbide adds about one pound of lime); reacts exothermically (producing heat) to not chill the slag; and under typical conditions does not dissolve in steel producing practically no carbon pick-up, no unexpected deoxidation, and nearly 100% utilization.

For this application, Carbide Industries can provide the grade size of calcium carbide that best meets the requirements of a particular application. Standard sizes range from 0.5" x 0.25" (13 mm x 6.5 mm) to 10 x 40 US-mesh (2 mm x 0.4 mm). For increased ease of application, these grades are available in smaller 2 1/2 and 5 gallon containers, in addition to the conventional 55 gallon drums and 2.5 ton bulk flo-bin containers.

In every case, consistent carbide purity and sizing are of special importance, especially with respect to oversize and fines.

Carbide has the unique ability to react only with metal oxides without adversely affecting steel chemistry, adding significant amounts of energy to the process. In the electric arc furnace (EAF) the energy produced during the oxide reduction is accompanied by the production of heated lime particles and CO gas which assist in retaining the heat generated while adding to the ability of EAF slags to foam.

In addition, since most of the slag that is generated in the EAF is not tapped into the ladle, all of the benefits of oxide reduction and alloy recovery that are well-known in ladle metallurgy are available to the EAF on a much larger scale.

The result is a much more energy-efficient, faster, higher yield, and higher alloy recovery EAF process.

For furnace injection, Carbide Industries produces carbide in a size range suitable for pneumatic transport to the furnace, where it is blown into the furnace with inert gas. Carbon injection ports that are marketed by several companies are entirely suitable for carbide injection. Carbide Industries LLC has also certified pneumatic equipment vendors that have the know-how to manufacture the tranport equipment. (Pictured is a MOCA pneumatic injector/transporter modified for use with calcium carbide produced by More s.r.l.)

While calcium carbide is utilized directly as a process material, its major use and perhaps its greatest versatility is realized when the rock-like substance is reacted with water to produce acetylene and calcium hydroxide. The unique chemistry of the triple-bonded carbon in the acetylene molecule allows for a variety of useful chemical reactions to form intermediates which are used in the manufacture of a diverse range of chemical derivatives.

Acetylene derivatives are used in a variety of everyday consumer products, including hair sprays, cosmetics, tabletted drugs, sun screens and lotions, antiseptics, and tartar-control toothpastes. In addition, acetylene intermediates provide the basic feedstock for the production of polyurethane fibers, synthetic rubber, perchloroethylene (a widely used dry cleaning solvent), trichloroethylene (a degreasing solvent used in metal working processes), and a new type of refrigerant gas which is designed to replace the environmentally damaging chlorinated fluorocarbons (CFC's) currently in widespread use.

Carbide Industries LLC generates large volumes of acetylene at the Calvert City, Kentucky, plant for distribution via pipeline to several specialty chemical manufacturers.

Calcium carbide is converted into acetylene in a controlled reaction with water using an apparatus called a generator. Acetylene, C2H2, is an extremely useful hydrocarbon due to the energy that is locked up in the triple-bond between the two carbon atoms. This energy is then released and utilized in different ways by our customers for a variety of industrial purposes.

Among the many uses of acetylene gas, the largest and perhaps the most familiar is its use in the form of cylinder gas for metal fabrication and construction. When combined with oxygen in an oxyacetylene torch, acetylene produces a flame temperature in excess of 6,000 degrees F, the hottest flame of all hydrocarbon gases. This provides the means to cut or join many types of metal, cleanse them of surface imperfections, and strengthen them through flame hardening. In addition, acetylene is lighter than air and is therefore the safest fuel gas to use in confined spaces, below ground, or on ships.

Carbide Industries LLC provides calcium carbide to both large national distributors of industrial gases and to numerous smaller, independently owned businesses, which generate acetylene for cylinder filling at locations throughout the US, Canada, and the Caribbean.
