Material and Technique

High quality 15% C magnesia carbon refractory bricks for electric arc furnace linings are produced by using fused magnesia and flake graphite as main materials, organic compounds as bonding agent, adding non-oxide additives, thus through mixing, high pressure pressed and heat treatment process.

Properties

Magnesia carbon bricks for EAF have good performance in high temperature resistance, high slag resistance, high thermal shock resistance and temperature creep resistance.

Application

1. Bottom

Refractory magnesia carbon bricks are mainly used for the bottom electrode of DC EAF, which can contribute to improve the service life of bottom electrode and enhance furnace running efficiency.

2. Taphole

Tapping spout and Taphole of eccentric bottom tapping electric arc furnace are also lined with magnesia carbon bricks.

3. Slag line

Refractory magnesia carbon bricks can be used in slag line of EAF.
