Carbon Graphite Block For Furnace Foundry Edm

Common Uses of Graphite Blocks

High-Temperature Furnaces

Graphite blocks are used as heating elements, insulation, or structural components in industrial furnaces for processes like sintering, annealing, and heat treatment.

Electrodes in Metallurgy

Used as electrodes in electric arc furnaces (EAF) for steelmaking and other metal refining processes.

Semiconductor Industry

Graphite blocks are used in the production of silicon wafers, as susceptors in chemical vapor deposition (CVD) systems, and in other high-purity applications.

Nuclear Reactors

Graphite blocks serve as moderators in nuclear reactors, slowing down neutrons to sustain nuclear fission reactions.

Chemical Processing

Used in reactors, heat exchangers, and other equipment exposed to corrosive chemicals due to graphite's chemical inertness.

Aerospace and Defense

Graphite blocks are used in rocket nozzles, thermal protection systems, and other high-temperature applications.

Foundry and Metal Casting

Used as molds, crucibles, or linings for melting and casting metals like aluminum, copper, and steel.

Energy Storage (Batteries)

Graphite blocks are used in some battery designs as conductive components or current collectors.

Electrolysis and Electrochemical Applications

Used as electrodes or current collectors in processes like aluminum production (Hall-Héroult process) or water electrolysis.

Laboratory and Research

Used in high-temperature experiments, as crucibles, or as sample holders.
