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 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:Is pig iron smelted in a graphite crucible?
In charge of limestone (CaO) from slagging, fluxing action, it can reduce the melting temperature of iron ore, iron and other elements also formed slag react, covering on the surface of the molten iron, molten iron and insulation protection.After the pig iron smelting, made pig iron ingot, sold to the market. According to the application of ingot has two kinds: cast iron and steel and iron.Casting pig iron: the fracture surface is dark grey, and the mass fraction of silicon is high. It is mainly used in the production of cast iron parts.Steel pig iron: the fracture surface is bright white, and the mass fraction of silicon is low. It is mainly used in the steelmaking process.
Q:What's the pot in the lab that puts in the oven?
There are many kinds of crucibles, such as cast iron crucibles, stainless steel crucibles, clay crucibles, graphite crucibles, silicon carbide and corundum crucibles.
Q:Which is a good quality graphite crucible?
The ordinary graphite crucible can not guarantee the safety in the high temperature environment, moreover, the conduction speed is slow in the test, which is not good for the experiment.
Q:How to select and use the carbon graphite for machinery? What items should we pay attention to?
Carbon - graphite is a brittle material whose mechanical strength is generally lower than that of metals. Therefore, in the design of the structure should pay full attention to this feature, in the processing and assembly process should be carefully operated, is strictly prohibited to strike with hard objects, to avoid rupture.
Q:Melting the iron in the graphite crucible. Does the graphite in the crucible turn into carbon and it melts into the steel?
In addition to carbon, charcoal contains hydrogen, oxygen, nitrogen, and a small amount of other elements. Carbon in charcoal is not a transition crystal like graphite, but amorphous carbon and no C-C covalent bonds. Charcoal ignition is 320-370 DEG C, the general fire than the high temperature, so the charcoal can be lit.
Q:How do you use crucibles to process copper?
Is actually very simple, dish stove, put on the container, the best graphite crucible, then copper into the graphite crucible, with high melting temperature, the melting of copper to copper in water, then pour you want to die production.
Q:Procedures for operating high temperature furnaces
A, check the power line contact is goodB, check if the connection is normalC, check if the cooling water is normalD, check the tightness is normalE, prepare the necessary tools: dust-free paper, anhydrous alcohol, canvas gloves, operating gloves, masks, high temperature gloves, graphite trolley, stainless steel tray
Q:Graphite crucible used six or seven times on how bad?
May be the temperature contrast is too large, cold, plus hot pot Meng, after use, and suddenly cooled, in the case of expansion and contraction, easily damaged.
Q:Application of ceramic fiber module in gas crucible furnace
From the way of heating, the crucible furnace has gas, fuel, electricity, coal, coke and so on. The life of the furnace crucible depends on the insulation material.
