What are the shapes of electrode paste and what are their uses?

Electrode paste is a conductive material used in electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces. It is made by dehydrating and melting petroleum coke and asphalt in a melting tank, adding them in proportion to a mixing pot for kneading, and then shaping and calcining them. Generally speaking, electrode paste has three shapes: trapezoidal, elliptical, and cylindrical. Below is a detailed introduction to the uses of these three types of electrode paste shapes:
-Trapezoidal electrode paste: mainly used in silicon manganese alloy ore furnaces, nickel iron alloy ore furnaces, silicon iron alloy ore furnaces, and silicon calcium alloy ore furnaces. After sintering, it can be used as an electrode.

Trapezoidal electrode paste

-Elliptical electrode paste: The use of elliptical electrode paste is similar to that of trapezoidal electrode paste, and it is also used in the four types of ore heating furnaces mentioned above. After sintering, it can be used as an electrode.

Elliptical electrode paste

-Cylindrical electrode paste: mainly used as an electrode after sintering in a calcium carbide furnace.

Cylindrical electrode paste

Electrode paste plays an important role in mining electric furnaces and is known as the "heart" of such electric furnaces. It can withstand high temperatures, with a small coefficient of thermal expansion and a relatively small resistance coefficient, which can reduce the loss of electrical energy. At the same time, it also has a small porosity, which can slow down the oxidation of the heated electrode, and has high mechanical strength, which is not easily broken due to the influence of mechanical and electrical loads.
