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 the silicon carbide crucible good for use? What's the difference between an ordinary graphite crucible and a graphite crucible?
The crucible can be placed on the iron tripod with either positive or oblique directions, and can be placed on the basis of the requirements of the experiment. When the crucible is heated, it cannot be immediately placed on a cold metal table to prevent it from breaking due to rapid cooling. It should not be placed on the wooden table immediately so as not to spoil the table or cause fire. The correct method is to cool the metal on the tripod or to let it cool slowly on the asbestos net. For crucible purposes, see the crucible tongs. The relevant information from the supply of silicon carbide crucible dachengxian Tianjin high silicon carbide crucible crucible factory released using the latest international technology of isostatic pressing method and strict quality assurance inspection system, using advanced refractory raw materials, high-tech formula developed a new generation of high-quality silicon carbide crucible, this product has a large volume density, high temperature resistant, fast heat, acid and alkali resistance, high temperature strength, oxidation resistance and high service life is 3 times that of the clay graphite crucible.
Q:Cast iron into a casting. What is the state of the matter, change, sublimation? Sublimation? melt
The corrosion resistance of acid and alkaline solution is strong, and it has good chemical stability. 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: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:Can quartz ceramic crucibles instead of graphite crucibles?
For the time being, I don't know what to replace. Since graphite was chosen, nothing else could be used.
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:What is the porcelain crucible with a small hole under it?
The main material of the graphite crucible is crystalline natural graphite. Therefore, it keeps all kinds of physical and chemical characteristics of natural right ink. That is: good thermal conductivity and high temperature resistance, in the process of high temperature use, the coefficient of thermal expansion is small, and has a certain strain resistance to hot and cold. The corrosion resistance of acid and alkaline solution is strong, and it has good chemical stability.
Q:What are the main components of a graphite crucible?
Engine cylinder head, brake, air filter, piston, radiator, steering wheel frame, and shell of mobile phone in electronic product, etc..The graphite crucible also needs attention when it is used: because the bottom of the crucible is very small, the crucible needs to be put on the graphite pad or the clay triangle when it is heated. The graphite crucible can be heated directly and can not be cooled immediately after heating and removed with a crucible clampDo not put it on the cold metal table to prevent it from breaking due to rapid cooling. Notice that the above points will extend the life of the graphite crucible.
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:Cast iron into a casting. What is the state of the matter, change, sublimation?
Cast iron into a casting. What is the state of the matter, sublimation?Container for molten iron called graphite crucible, good high-temperature resistance, it is higher than the melting point of iron.
Q:Graphite and diamond are elemental elements made of carbon. Why are physical properties so different?
diamondDiamond is pure carbon, graphite and chemical properties are basically the same, but the physical properties are not the same. The diamond carbon atoms is a tetrahedral solid, a Pyramid shaped structure, the overall shape of the crystal was eight, the structure is very stable, which leads to the hardness of diamond is very high. In addition to diamond almost non-conductive, hard material is the most natural, it is of poor thermal conductivity, high melting point, colorless and transparent.
