The temperatures involved in the production of calcium carbide mean that only professionals trained in the use of the required equipment should attempt to make calcium carbide. Crush the solid calcium carbide in either an open-air setting or inert environment prior to it cooling completely. Failure to do so can lead to an explosion hazard.
Sep 20, 2019· Calcium carbide is a compound produced from a thermally converted combination of coke and lime. It has several industrial applications, the most frequently encountered being the production of acetylene gas. Acetylene is widely used as a less costly alternative to traditional petroleum-based heating fuels in a number of industrial processes.
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.
The calcium carbide process feeds coke4. pre-mixed with lime chunks (calcium oxide, (CaO)) to the EAF, and the electrodes protrude through the furnace cover into the pile of coke and lime. As the EAF provides electricity, heating the feed material to temperatures above 4100°F,
