Graphite Block

The advantages of graphite blocks in the metallurgical field include high-temperature resistance, excellent conductivity, and corrosion resistance, contributing to equipment stability and enhanced production efficiency.

Graphite Carbon Block is a kind of carbonaceous refractory material made from coke, anthracite or graphite, and tar as raw materials after being mixed and shaped, and burned to 1450℃ in reducing flame. The carbon mass fraction is 88% to 90%. It can resist the erosion of molten metal and various slag, but it is easy to be oxidized. It’s used for masonry bottom and hearth of blast furnace.

Application
Graphite blocks are mainly used in three aspects:

Utilizing its excellent conductive properties as conductive materials, such as anodes of magnesium electrolytic cells, conductive electrodes and end walls of graphitization furnaces.

Use its excellent thermal conductivity and corrosion resistance as refractory materials, such as the bottom masonry of iron-making blast furnaces.

Using graphite blocks as the matrix, mechanical processing, impregnating and curing with synthetic resin or other liquid impregnating agents to produce chemical equipment, such as block graphite heat exchangers.

Advantage:

Graphite blocks have several advantages, including:

Strong conductivity: Graphite blocks are excellent conductors, suitable for various electrical and electronic applications. They exhibit good electrical and thermal conductivity, thus finding wide use in batteries, electrolytic cells, conductive lubricants, and more.

High chemical stability: Graphite blocks demonstrate stability in many chemical substances, resisting acids, alkalis, solvents, etc., making them extensively used in the chemical industry.

Good mechanical properties: Graphite blocks possess a certain level of strength, hardness, and elasticity, enabling them to withstand certain pressures and abrasion in mechanical applications.

Excellent high-temperature resistance: Graphite blocks maintain stability at high temperatures, resisting thermal stress and thermal shock.

Good lubrication properties: Graphite blocks act as effective lubricants at high temperatures, serving as lubricating additives, for instance, in manufacturing mechanical components.
