China Graphite Crucible For Metal Smelting

Key Benefits

• Technological Merit


• Good mechanical strength


• Long life: Due to a the excellent chemical stability, corrosion, erosion and temperature resistance, the material is afforded a long lifespan.


• High heat conduction performance and resistance to thermal shock: Possible to use even at 2760°C in inert atmosphere, high thermal shock resistance at high temperatures.


• Excellent corrosion resistance: Resistance is excellent against a wide range of acid and alkaline environments, great degree of chemical stability.

Specifications from the graphite crucible :

1.Long working lifetime: its working lifetime is increased 3-5 times over normal clay-crucible due to the compact body formed under    high pressure.

2.High thermal conductivity: high-density body and low apparent porosity greatly improve its heat conductivity.

3.New-style materials: new heat conduction material ensures faster heat conductivity and pollution-free product, reduces adherent slag.

4.Resistance to corrosion:better anti-corrosion than normal clay-crucible.

5.Resistance to oxidation: advanced process dramatically improves its oxidation resistance, which ensures persistent heat conductivity and long working lifetime.

6.High-strength: high-density body and logical structure make the product better compression property.

7.Eco-friendly: energy-efficient and pollution-free, not only ensure metal product purity, but also ensure sustainable development on environment.

 

NOTICE: We also supply Copper-melting Clay Graphite Crucible and Aluminum-melting Clay Graphite Crucible. Meanwhile, a matched graphite stand is strongly recommended in order to expand the lifetime and improve heat conduction of crucible.

 

The crucible is  an utensil or melting tank vessels that is made of refractory material (such as clay, graphite, clay, quartz or difficult molten metal iron, etc.).

Graphite crucible, which is divided into general type of graphite crucible, special type of graphite crucible, high purity graphite crucible.Graphite crucible, which is divided into general type of graphite crucible, special type of graphite crucible, high purity graphite crucible.

The main raw materials of Graphite crucible is natural crystalline graphite. Therefore, it maintains the original natural graphite various physical and chemical properties.

Graphite crucible has good thermal conductivity and high temperature resistance;Uder the high temperature, the thermal expansion coefficient is small, rapid heating, quench with certain anti-strain properties. The strong corrosion resistance of acid, alkaline solution has excellent chemical stability.

Graphite crucible, with their more excellent performance, in metallurgy, casting,mechanical, chemical and other industrial sectors, is widely used in smelting and alloy tool steel smelting of non-ferrous metals and their alloys . Besides,it has achieved a good technical and economic results.
