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:How to improve the service life of graphite crucible
From the product point of view:1., raw materials are chosen from natural graphite to ensure that the graphite is not easily oxidized;2. cold isostatic pressing process is adopted to ensure high density and strength of crucible;3., the crucible surface high temperature, low temperature protection glaze layer, isolated oxygen and graphite contact contact;From the production point of view:1., scientific warming, to prevent cold, hot;2. add proper and proper amount of refining agent;3. do not stop the furnace abnormally;
Q:How long is the service life of the cast iron crucible?
The service life of cast iron crucibles for electric furnaces ranged from 1 months to 2 months.
Q:Help: how can the graphite crucible be heated to 1000 degrees?
The fastest speed is the electromagnetic heating
Q:What are the carbon elements? What are their structures? What are their properties and uses?
C60 molecule is a molecule made up of 60 carbon atoms. It is similar to football, so it is also called "football"C60 is a stable molecule formed solely by carbon atoms. It has 60 vertices and 32 faces, of which 12 are pentagonal and 20 are regular hexagons. The relative molecular weight is about 720.
Q:What is graphite?
Of the six Fang system with a complete lamellar cleavage. The cleavage surface is mainly based on molecular bonds, and has weaker molecular attraction, so its natural floatability is very good.
Q:How to break 40 low carbon steel smelting
Only by argon arc welding in small diameter pipes, piping, is a commonly used method for ITU argon welding section, then replace the consumption of electrode for welding wire, ultra low carbon in the coefficient multiplied by 1.15.
Q:What graphite crucible is used to smelt aluminium by electromagnetic induction heating?
Electromagnetic induction heating is the heating of graphite, and can soon rise to 1000 degrees, but aluminum is a magnetic material, will block the electromagnetic field, so this scheme is not feasible
Q:How to select and use the carbon graphite for machinery? What items should we pay attention to?
Selection must be based on the working conditions of the equipment, taking into account the pressure, wire speed, medium, and grinding materials and other factors, if necessary, after the test selected appropriate.
Q:How to extract pure silver from sundry Silver
The precipitation of silver chloride solution: according to the volume of silver nitrate, and then added according to the volume ratio of about l% concentration of 16% hydrochloric acid, the production of white silver chloride precipitate. For clarification, pumping liquid holding, will precipitate wash with water 2 to 3 times, to reach the neutral.
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. It is necessary to determine the material or grade of the graphite to have the corresponding technical parameters. The letter Ruida graphite thermal field | graphite heater | graphite crucible | isostatic graphite, when processing will also consider these problems, depends on the specific application!
