Electrode Paste
ELECTRODE PASTE
Electrode paste is a conductive material used in ferroalloy furnaces, calcium carbide furnaces and other ore-arcing furnaces. This product has a small resistivity which can reduce the loss of electric energy, has small pores, can slow down the oxidation speed of the heated electrode,is resistant to high temperatures, has a small thermal expansion coefficient, and has high mechanical strength.
SEALING PASTE
This product is used in closed submerged arc furnaces that require good sintering performance of electrode paste. lt has good thermal stability, low-temperature melting and certain fluidity, low resistance and high mechanical strength. After sintering, it is resistant to high temperature oxidation and seismic.
