This provides the means to cut or join many types of metal, cleanse them of surface imperfections, and strengthen them through flame hardening. Carbide Industries LLC has also certified pneumatic equipment vendors that have the know-how to manufacture the tranport equipment. Calcium gluconate is used as a food additive. Acetylene is widely used as a less costly alternative to traditional petroleum-based heating fuels in a number of industrial processes. Online Posting Date: 25 Jun 2010. Acetylene, C2H2, is an extremely useful hydrocarbon due to the energy that is locked up in the triple-bond between the two carbon atoms. Acetylene is also extensively used world wide in oxy-acetylene cutting and welding applications. Holzrichter K et al; Calcium Carbide; Ullmann's Encyclopedia of Industrial Chemistry 7th ed. 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. These specialized products are formulated to help eliminate the retention of unreacted carbide in the resulting desulfurization slags and also to minimize slag odor. In addition, acetylene is lighter than air and is therefore the safest fuel gas to use in confined spaces, below ground, or on ships. 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. Carbide is an essential tool for the removal of unwanted iron oxide from furnace slag that is carried into the ladle during tapping. Calcium carbide has three main uses: the manufacture of acetylene, ... reaction with nitrogen to give cyanamide ... and the desulfurization of hot metal, cast iron, and steel. The Merck Index - An Encyclopedia of Chemicals, Drugs, and Biologicals. 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. Reducing agent, e.g. The crystals will turn into a gas, filling the mole tunnels. Hi and many thanks for your interest in this article. It has several industrial applications, the most frequently encountered being the production of acetylene gas. At Carbide Industries, calcium carbide production in different sizes (grades) is all we do. New York, NY: John Wiley & Sons. Cameron W; Calcium Carbide. (Pictured is a MOCA pneumatic injector/transporter modified for use with calcium carbide produced by More s.r.l.). Your concerns are very valid and I will attempt to clarify this point for you ASAP. Carbide has the unique ability to react only with metal oxides without adversely affecting steel chemistry, adding significant amounts of energy to the process. Furthermore, left untreated, these oxides can interfere with the downstream steel refining operation by inhibiting desulfurization, oxidizing ("fading") alloy additions, and attacking refractories. Online Posting Date: June 15, 2000. A product of the high temperature conversion of coke and lime mixtures, calcium carbide produces large quantities of acetylene gas when exposed to water. 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. 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.
