Super Quality Long Working Life SiC Graphite Crucibles

 

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:Can sintering rare earth fluorides be made of corundum crucibles?
If it is 700-800 degrees, you can consider using graphite crucible, it is aluminum (aluminum alloy temperature 700-900 degrees) with the best refractories, life expectancy in about half a year, you can understand!
Q:How do you use crucibles to process copper?
The medium frequency furnace crucible is made of quartz sand lining material, and the crucible has a long service life, usually in three months. The power frequency furnace is also sintered with quartz sand.
Q:What crucible can be used to make steel? At least 1500 degrees resistant
BOF is carried out in the converter. The converter is shaped like a pear, wall brick, oven side holes (outlet), compressed air from these holes blowing furnace, also called side-blown converter. Initially, the converter at the level of 1300 degrees Celsius, inward injected liquid raw lime and iron. Adding a certain amount of air, and then make it stand upright and rotate the converter.
Q:What is the porcelain crucible with a small hole under it?
Is the crucible, crystalline form of natural graphite as the main raw material, plastic refractory clay as binder, refractory graphite crucible with different types of clinker with which is mainly used in smelting special alloy steel, nonferrous metals and alloy melting. Graphite crucibles are an integral part of refractories in terms of their properties and uses.
Q:How long will it take to warm the water at 20 degrees to 3000 degrees at 3800?
You don't want it either, because the thermodynamic chart is the highest, that is, the superheated vapor data of the 1000C. In addition, in the absence of a catalyst, at 1800K and 1mmHg, the water vapor begins to decompose into H2, O2, H, O, OH. At 3500K, all the water vapor breaks down into H, O atoms.
Q:How long can a graphite crucible last for a long time?
High temperature resistance, graphite melting point is very high, in the vacuum of 3850 degrees, sublimation at low pressure, sublimation temperature of 2200 degrees, and the general material is different
Q:What is the difference between the indirect method Zinc Oxide and the direct law Zinc Oxide?
The direct method of Zinc Oxide in a variety of zinc ore or debris as raw material. Zinc Oxide and coke in the reaction when heating is reduced into metallic zinc by the steam, and then oxidation by oxygen in the air for Zinc Oxide, Zinc Oxide to remove most of the impurities. The direct method to obtain coarse particles, the product purity was 75%-99.5%.
Q:Why does China choose quartz crucible directly in the aspect of Czochralski silicon?
Hello, quartz crucibles are the necessary accessories for CZ crystals. They have not been heard to replace quartz crucibles. You are new enough.
Q:Will the friction powder of the graphite sliding bearings rust?
The letter Ruida graphite thermal field | Rita graphite mold | letter letter Ruida lightning protector graphite | isostatic graphite graphite | surge | Ruida letter letter letter Ruida Ruida graphite products | graphite vacuum furnace | Rita graphite crucible | letter custom processing | graphite graphite powder |EDM graphite |10/350 surge graphite sheet for you to answer the above point of view, for reference only!
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.
