A STEP CHANGE IN CALCIUM CARBIDE PRODUCTION TECHNOLOGY

Calcium carbide production continued to expand rapidly into the 20th century and by the late 1950s and into the early 1960s the carbide chemicals industry was at its peak, with world production of calcium carbide estimated at well over eight (8) million tonnes per year (1962), with more than 90% of this in North America, Europe and the Soviet Un-ion [3]. However, the advent of other routes for ...

Calcium Carbide - an overview ScienceDirect Topics

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).

Calcium Carbide Applications - Carbide Industries LLC

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 ...
