Graphite electrode development history

In 1810, charcoal electrodes were made from charcoal.
In 1846, Stewart and Edward mixed with coke powder and sucrose, pressed and formed at a high temperature to produce another carbon electrode.

In the early 20th century, electric steelmaking mainly used carbonaceous electrodes with anthracite as raw material or natural graphite electrodes with natural graphite as raw material.
In the 1960s and 1970s, high-power and ultra-high-power graphite electrodes were successfully developed.
