The graphite spoon for scooping high temperature metal solutions
A: Company profile
L.T Group has a comprehensive product and technology portfolio that focuses on four field
of graphite - ultrafine particle graphite mould, graphite electrode, graphite crucible, as well as
other products mainly made of graphite.
Graphite materials exhibit unique properties such as good electrical and thermal conductivity,
heat and corrosion resistance, low friction, and reduced weight while at the same time maintaining
high strength. Due to the shortage of energy and raw materials, our high performance products
made from graphite are in increasingly high demand in industries. They also play a progressively
important role in everyday life, thereby substituting traditional materials.
B: Why choose us
The graphite spoon can be used for scooping high temperature metal solutions. The graphite spoon has good corrosion resistance, good chemical stability at room temperature, acid and alkali resistance and corrosion resistance of mailing solvents.
Our mold features:
Raw materials is very important, We only use Ultrafine particle structure, High purity and High
graphitization raw graphite materials.
Our finished graphite mold is:
a: dense structure and low porosity
b: Fined surface and low rate heat-deformation
c: High mechanical strength and machining accuracy
d: Oxidation resistance and durable
C: Product features
Due to its special structure, graphite has the following special properties:
(1) High temperature resistance
The melting point of graphite is 3850±50ºC. Even if it is burned by an ultra-high temperature arc, the weight loss is very small, and the thermal expansion coefficient is also small. The strength of graphite increases with increasing temperature, and at 2000°C, the strength of graphite doubles.
(2) Electrical and thermal conductivity
The conductivity of graphite is one hundred times higher than that of ordinary non-metallic minerals. The thermal conductivity exceeds that of metal materials such as steel, iron, and lead. The thermal conductivity decreases with increasing temperature, and even at high temperatures, graphite becomes a thermal insulator. Graphite can conduct electricity because each carbon atom in graphite forms only 3 covalent bonds with other carbon atoms, and each carbon atom still retains 1 free electron to transport charges.
(3) Lubricity
The lubricating performance of graphite depends on the size of the graphite flakes. The larger the flakes, the smaller the friction coefficient and the better the lubricating performance
D: Processing method
1. Customer provide design drawings.
2. Our technical team will check, analyze the drawings, and divide the drawing to reasonable parts
if needed, and prepare proper graphite blocks .Our mechanics will design and customize grinding wheel.
3. Our workers will grinding and polishing graphite block according to the instructions of mechanics.
This process may need operating few times if needed.We will strictly keep deviation within ±0.03-0.08mm.
4. Then our packing team will assembling different parts into a whole graphite mold.During the
assembling period, unqualified products will be picked out.
