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:Is graphite crucible resistant to hydrofluoric acid?
The graphite crucible has a maximum temperature of 1800 degrees Celsius and can be used for a long time! But generally graphite crucibles are used below 1300 degrees celsius!
Q:Cast iron into a casting. What is the state of the matter, change, sublimation?
In metallurgy, casting, machinery, chemical and other industrial sectors, it is widely used in smelting of alloy tool steel and smelting of nonferrous metals and their alloys. And has better technical and economic results.
Q:How is graphite formed?
1 isostatic pressed graphite. That's what a lot of people call "three high" graphite, but not three highs or equal pressure.2, molded graphite
Q:Electromagnetic induction heating device into the copper coil heater, to use more power consumption to reach the melting temperature of iron?
Ten on the theory but can't stand hot kilowatts, ah
Q:How should CPP aluminium plating film be produced?. Is the vacuum aluminizing machine necessary? How much is the machine?. What material does CPP aluminum plating film need?.
CPP film is aluminum barrier films by vacuum aluminum plating process will be a thin layer of aluminum atoms accumulated to CPP film formed on the casting quality, with metal luster bright, excellent gas and light resistance and good moisture, light, can use the advantages of replacing aluminum foil.
Q:Does the silicon carbide graphite Tong have a magnetic field in the intermediate frequency furnace?
Good crack resistance, corrosion resistance and oxidation resistance - 5-10 times the quality of ordinary graphite crucibles2., shorten the dissolution time, good heat transfer, high thermal conductivity, energy saving - energy savings 2/5-1/33. long service life
Q:Graphite products are mainly used in what industry?
Graphite has good chemical stability. After special processing of graphite, with corrosion resistance, good thermal conductivity, low permeability, is widely used in the manufacturing of the heat exchanger, the reaction tank, condenser, combustion tower, absorption tower, cooler, heater, filter and pump equipment. Widely used in petroleum, chemical, hydrometallurgy, acid and alkali production, synthetic fiber, papermaking and other industrial sectors, can save a lot of metal materials.
Q:Cast iron into a casting. What is the state of the matter, change, sublimation? Sublimation? melt
The graphite crucible has good thermal conductivity and high temperature resistance, and the thermal expansion coefficient is small in the process of high temperature use, and has a certain anti strain property for hot and cold quenching.
Q:What is the conductivity of graphite and copper, iron and zinc?
Graphite and copper, iron, and zinc are electrically conductive. The conductivity and thermal conductivity are different for different grades of materials.
Q:What is the importance of carbon graphite as biological material?
What is the importance of carbon graphite as biological material?Because graphite has many excellent properties, it has been widely used in metallurgy, mechanical, electrical, chemical, textile, national defense and other industrial sectors.
