11.4 Calcium Carbide Manufacturing
of lime, 683 kg (1,506 lb) of coke, and 17 to 20 kg (37 to 44 lb) of electrode paste are required to produce 1 megagram (Mg) (2,205 lb) of calcium carbide. The process for manufacturing calcium carbide is illustrated in Figure 11.4-1. Moisture is removed from coke in a coke dryer, while limestone is converted to lime in a lime kiln. Fines from
AP42 Section: 11.4 Calcium Carbide Manufacturing Title: Comments
calcium carbide is the coal tar pitch binder in the furnace electrode paste. Because the maximum volatiles content . in . the electrode paste is about . 18 . percent, the electrode paste represents only a small potential source of hydrocarbon emissions. electrode paste typically furnaces, actual hydrocarbon emissions from the consumption . of
Cylinder Soderberg Electrode Paste For Calcium Carbide Production
Products Description. Cylinder Soderberg Electrode Paste For Calcium Carbide Production is used as self-baking electrodes for submerged arc furnaces,Cylinder Soderberg Electrode Paste For Calcium Carbide Production is a kind of carbon products,consisting of ECA,CPC and graphite powder,with the coal tar pitch as the binder,after the mold shaping.During the application,the paste will be put into ...
Use Of Electrode Paste
Soderberg Electrode paste is widely used in ferroalloy electric furnace and calcium carbide furnace because of its simple process and low cost. The performance of soderberg electrode paste is not different from that of carbon electrode when the electrode is baked well, but its manufacturing cost is only one-eighth of that of graphite electrode.
Carbon Electrode Paste – Maruti Electro Carbon
Carbon Electrode Paste. Electrode Carbon Paste is a Soderberge paste processed from a mix of a specific fraction and / or Electrically Calcined Anthracite Coal – ECA, impregnated with selective Coal Tar Pitch. It is used in submerged Arc Furnaces for production of Ferro Alloys and Calcium Carbide.

Electrode paste composed of coal tar pitch binder and anthracite coal is fed into a steel casing where it is baked by heat from the electric arc furnace before being introduced into the furnace. The baked electrode exits the steel casing just inside the furnace cover and is consumed in the calcium carbide production process.
