Question

Accepted Answer

EAF is an electric arc furnace used for steelmaking. It uses electricity to melt scrap steel and other materials.

EAF uses graphite electrodes to create an electric arc that melts the scrap steel.
The size of electrodes varies depending on the size of the furnace.
The life of EAF depends on the quality of the refractory lining and the frequency of use.
Refractory lining is made of materials like magnesia, alumina, and silica.
Hydraulics are used to control the movement of the furnace lid and electrodes.
Different types of valves are used for controlling the flow of gases and liquids in the furnace.
Nass value is a measure of the amount of nitrogen in the steel.
PCD of EAF electrode refers to the pitch circle diameter of the electrode holder.
The material of the Cu head is usually copper or copper alloys.
Proportional valves are used for precise control of fluid flow.
Servo valves are used for high-precision control of fluid flow.
Vacuum degassing is a process used to remove impurities from the steel.
LRF stands for Ladle Refining Furnace, which is used for refining the steel before casting.
Cover car is used to cover the furnace during the melting process.
Cranes are used for charging the furnace with scrap steel and other materials.
