Graphite Electrodes
Graphite electrodes are conductive members of an electric
steel-making furnace, which recycles scrap iron to manufacture
steel products.
Since graphite electrodes are used under high temperature and
oxidation atmosphere, they require low electric resistivity and
thermal shock resistance.
The product is a large-size pillar-shaped graphite material with
a maximum diameter of 800 mm and length of 3,000 mm.
High-temperature heat treatment technology
Raw materials are extruded, baked and then heat-treated at high
temperature in a graphitizing furnace.We have the know-how
(energization schedule, inter-electrode connection method,
protection of the furnace body from high heat, etc.) to control the
properties of the final products and heat-treat the materials with
good yield.
