Product Description

 

Specifications for Graphite Silicon Carbide Crucible For Aluminum Melting :

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.

8.Multi-function: Can be used in induction graphite crucible furnace

Physicochemical Properties of graphite crucible:

 

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

Graphite crucible, with is special advantages and Plasticity, is widely used in the smelting area, e.g. gold smelting, silver smelting, aluminum smelting, cooper smelting, etc.

Q:What magnetic material is sintered with large corundum crucible?
The graphite crucible is a high temperature resistant and difficult to sinter material, but the biggest problem must be used in a vacuum or a reducing atmosphere. Otherwise, graphite is easily oxidized at high temperature. And the crucibles are more expensive.
Q:Can graphite products be calcined in air for a long time?
Graphite products are characterized by high thermal conductivity, and stable performance at high temperatures, in the use of the process, even if the temperature is very high, still able to maintain good performance. Graphite crucible thermal expansion coefficient is very small, in the cold, hot situation is still very little impact on the performance of the crucibleGraphite crucible is superior in smelting, alloy, tool steel, non-ferrous metals and other alloy smelting has good advantages, so it is widely used in metallurgy, casting, machinery, chemical and other industrial sectors. The application of the graphite crucible has a good effect both technically and economically.
Q:What are the components of a pencil core?
Graphite is an allotrope of elemental carbon around each carbon atom attached to three other carbon atoms arranged in a plurality of hexagonal honeycomb, each layer between the Fan Dehua gravitational weak. Since each atom emits an electron, the electrons are free to move, so the graphite belongs to the conductor. Graphite is one of the most soft mineral, opaque and feel greasy, color from black to gray iron, the shape of a crystal, thin, squamous, striped, layered or scattered in the metamorphic rocks. Chemical properties are inert and corrosion resistant.
Q:Why does the graphite crucible used for molten gold add a quartz coat?
Graphite crucible is afraid of high temperature, but high temperature oxidation, Shi Huang coat is not oxidized to protect the crucible.
Q:Why graphite and diamond is composed of carbon graphite, but not light, is black, and the diamond is urgently in light!
Although they are all carbon, the arrangement of the carbon atoms is different, so different structures lead to different physical properties
Q:What are the main changes in graphene supercapacitors?
What are the main changes in graphene supercapacitors?"
Q:What are the welding methods at the end of the thermocouple?
Argon arc welding type K thermocouple argon arc welding equipment consists of 5 parts, such as DC welding power supply, high frequency oscillator, welding gun, welding power supply and clamp. When welding, the cerium tungsten wire extending out of the welding nozzle is used as the negative electrode, and the welding thermocouple is fixed on the fixture as an anode. When the poles by high frequency and high voltage when the arc ignition function, using thyristor voltage control, arc intensity, under the protection of argon to cerium tungsten and generating arc discharge between welding thermocouple, high temperature generated by the arc melting end of the thermocouple wire into a ball. In order to facilitate the alignment of the thermocouple with the electrode, the work fixture and the welding torch can move in both horizontal and vertical directions. The welding torch is equipped with cerium tungsten electrode of diameter 1mm and 1.5mm, which is used for welding thermocouples of different diameters.
Q:Application of ceramic fiber module in gas crucible furnace
The ceramic fiber module plays a major role in fireproof and heat preservation in the gas clamp boiler, and prolongs the service life of the Tong boiler. According to the different materials of the gas tongs boiler, the refractory and heat preservation materials used are different, and the ceramic fiber module, refractory fiber board and refractory pouring material are all the heat preservation materials used by the conventional clamp boilers.
Q:What is the aluminum crucible?
The crucible of aluminium melting can be sintered by neutral sand in medium frequency electric furnace. Melting crucible is made. The service life is more than 300
Q:Is the jade pressed by the machine natural?
The market of jade mainly have three kinds, namely a cargo, B goods and C goods, which refers to the goods without any manual optimization of natural jade is genuine genuine goods at a fair price. B goods after a strong acid cleaning, inside the note of glue, although after polishing, but the surface will still have acid corrosion pattern, this kind of goods after a period of time will be yellow. C goods is a dyed emerald, usually with colorless, light colored and water head better low-grade jade artificial dyeing, and a long time will fade.
