High quality graphite blocks

1. Material: Molded,Impregnated graphite 2.Good machine surface 3.Quality is steady

MATERIAL:

 

Extruded Graphite,Molded Graphite,Isostatic Graphite,Vibration Graphite,High density and high Flexural Strength graphite material . (Die molded graphite),High pure extruded graphite,Special carburizing treatment graphite material

CHARACTERISTIC :

1.perfect sealing performance , long service life , low maintenance

2. high thermal and chemical resistance , good thermal conductivity , low coefficient of thermal expansion , minimal wettability to molten metals

3 . High pure mold graphite means fine gain, high pruity-strength-density. Graphite products using the fine quality coke(low ash content) as its raw material.

It is made in a scientific formula through the process of mixing, pressing, baking and graphitization (above 2500 degrees).

Therefore, it has the good properties of high temperature resistance, high electric and thermal conductivity, good lubricity. and is widely used in the electronic,mechanical and chemical industry.etc.

It can be used as rectifier graphite anode, mold for electronics agglomeration, consitantly casting graphite crystallizer, accurate casting, the melting of semiconductor and rare metals, graphite crucible, mechanical seal in some fields as chemical industry, electrospark machining discharge anode,etc.

APPLICATIONS:

1. Apply to graphite anode, graphite mould , graphite pallet . used for chemical  metallurgy, electronic industry and textile. etc

2. Machine to Electrodes, anodes, cathodes, heating elements, resistors, fluxing/degassing tubes, molds, crucibles, special structural parts, etc. in metallurgy, mechanical engineering, chemical & electrochemical industry, energy management, glass & ceramics, transportation and other industries.

3. Molds in continuous casting systems for making shaped steel, cast iron, copper;  Sintering molds for cemented carbides, diamond tools and electronic components; 

4. Molds for making shaped glass;   Crucibles for melting precious metals or alloys; 

5. Electrodes for EDM;      Heating elements, heat shields, crucibles, boats in furnaces for pulling monocrystalline silicon or optical fibers;  Anodes for production of manganese dioxide, metallic magnesium and rare metals; 

6. Graphite Blocks are molded or extruded or isotropic or vibrating graphite blocks. It is mainly used in the metallurgy or resistance furnaces such as carborundum or graphitization furnaces as the lining material, electric conduction material or impermeable graphite heating converters.

 

 High density and high Flexural Strength graphite material . (Die molded graphite)

Featrue:   High density, Fine grain size, High purity, High strength, Low specific resistance, Ease of precise machining Excellent thermal shock resistance to high temperature and oxidation ,Good anticorrosion .
