Commercial Production of Calcium Carbide and Acetylene. Failing to find anyone willing to buy their calcium carbide and acetylene patents, Morehead and Willson turned their attention to finding and promoting uses for the products themselves, beginning with acetylene in lighting.
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. Applications of calcium carbide include manufacture of acetylene gas, and for generation of acetylene in carbide lamps; manufacturer of chemicals for fertilizer; and in steelmaking.
Published March 2017. Calcium carbide is an inorganic compound with the following primary commercial applications: generation of acetylene, production of calcium cyanamide (a nitrogen fertilizer), and use in the iron (foundry) and steel industries as a desulfurization reagent in the production of ductile iron and steel and as a slag modifier/conditioner (reducer) in steel production.
The aim is geared towards using calcium carbide waste and bamboo leaf ash as partial replacement of cement in bid to achieve this aim, the specific objectives are to: • determine the chemical composition of calcium carbide waste powder (CCWP), bamboo leaf ash (BLA) and Ordinary Portland cement (OPC).
New Calcium Carbide Production Plant, Blast Furnace Slag Pulverizer Introduction : Calcium Carbide Production Plant, Blast Furnace Slag Pulverizer --- LM vertical grinding mill is a kind of large scale powder making mill which is designed specially to solve the problems of low capacity and high consumption of industry mills.
Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of Ca C 2.Its main use industrially is in the production of acetylene and calcium cyanamide.. The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC 2 (the rest is CaO (calcium oxide), Ca 3 P 2 (calcium phosphide ...
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.
Calcium carbide powder and magnesium granulates are used in the steel industry for desulphurisation or deoxidation purposes. Calcium carbide granulates are used for the production of acetylene, a welding gas. The fine for Evonik Degussa was increased by 50% because it had previously taken part in similar infringements.
Described herein is the production of tungsten and tungsten carbide in powder form by chemically reducing to tungsten oxide a tungsten compound containing less than 100 ppm total of the elements, sodium, potassium, and calcium, and thereafter chemically reducing the tungsten oxide to tungsten powder with dry hydrogen having a dew point not higher than -30*F.
In order to cater the variegated demands of our precious clients, we have come up with a qualitative grade Calcium Carbide.

Cement industry is the best way for calcium carbide residue to be harmless, large dosage, no residue and resource treatment, and calcium carbide residue production cement is the best way for calcium carbide residue cleaning treatment.Because the decomposition heat of calcium carbide slag is much lower than that of limestone, the coal ...
The invention relates to a production method of calcium carbide, which takes coal powder and calcium oxide as raw materials. According to the method, the coal powder is crashed to 120 meshes, and then mixed with the calcium oxide at the weight rate of 1:0.8 to 1. A certain amount of water is added into the mixture which then can be stirred to be even and compressed into cubic honeycomb blocks ...
