Product Description:


Features

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: highdensity body and low apparent porosity greatly improve its heat conductivity.

3.Newstyle 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

Product Uses

1. Graphite crucible cannot be exposed in moisture, and must be placed in indoor dry place or wooden shelf. Maintain ventilated. Moisture is strictly prohibited. Damped crucible is likely to crack.

 

2. Each crucible, especially damped ones, must be preheated and roasted in drying equipment or next to a ground furnace before use. The roasting temperature should start from a low temperature of 100°C below. Roast it to 150°C at a speed of not higher than 30°C per hour. Preserve the heat for about 8 hours and then dry it. The crucible dried next to a ground furnace should be placed at least for one shift, and often turned to change direction, till workers feel the internal wall of crucible is hot.

 

3. The melting time for the first time should be at least twice of the normal melting time, in order to avoid cracking inside the crucible due to heating up too fast, or even cracking immediately when the fire sets on.

 

4. Handle with care. Falling or shaking is strictly forbidden in order to present cracking. Crucible should be placed below the mouth of furnace to prevent the furnace lid abrading the upper edge of the crucible and thus affecting the capacity.

 

5. Pour out the remaining cold metals inside the crucible after use, and then add new materials. Carefully and gently add new materials into the crucible. Feed materials according to the capacity of crucible. It is not allowed to feed too many materials, in order to prevent crucible from swelling or bursting.

 

6. Knock gently to remove slags and cokes on the internal and external wall of the crucible. Avoid damaging the crucible body.

 

7. In the melting process, do not add chloride solvents in order not to corrode the crucible. For the furnace that uses oil and coal gas as fuels, the oil wind should not reach one part of the crucible directly. Turn around the crucible from time to time, in order to avoid local damage.

 

8. Clamps and other discharging tools should comply with the shape of the crucible. During furnace discharging, remove the cokes on the external wall of the crucible, and lower the furnace temperature; do not discharge at high temperature after stopping blasting. Clamp the upper and middle parts instead of the top of the crucible in order not to damage the crucible. Graphite crucible is used mainly to melt gold, silver and other precious metals.

Q:Excuse me, carbon steel, carbon steel pipe, seamless steel pipe, spiral steel pipe, what is the difference?
There is no joint in the whole. The material can be used according to the needs, often used for high temperature, high pressure and other fluids. Hence, it is called seamless steel tube. The spiral steel tube is also formed by the heating and rotating of the strip steel. The utility model is suitable for the fluid below 30Kg, and the material can replace the seamless pipe with the big caliber and difficult to be manufactured according to the requirement, and is suitable for the medium and low pressure fluid with large caliber.
Q:How to distinguish carbon rods to identify carbon fishing rods?
I'm also waiting to learn! It seems all very busy, the masters are not on-line
Q:What is the difference between carbon and carbon materials?
Carbon refers to elements. Carbon materials usually refer to materials that contain carbon and are the main bodyCarbon is a carbon containing substance of no composition and property consisting of carbon elementsCarbon materials are usually specified, especially carbon and graphite materialsCarbon material is a broad carbon containing materialAbove.
Q:Carbon steel with carbon steel, carbon steel yuan yuan is the same? The trouble to know the answer urgently
Nor can we see carbon steel and carbon circle are called carbon circle. If the carbon steel and carbon circle are called carbon that are circular steel.
Q:Why is carbon content of stainless steel low?
The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steel is lower, the maximum is not more than 1.2%, and some steel's Omega C (carbon content) is even less than 0.03% (such as 00Cr12). The main alloying element in stainless steel is Cr (chromium), and the steel has corrosion resistance only when the Cr content reaches a certain value. Therefore, stainless steel in general Cr (chromium) content of at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements.
Q:Iron and steel are different in terms of carbon content
That is, high manganese content, less nickel or nickel free stainless steel. This stainless steel market costs more than 1000 yuan per ton of stainless steel with nickel. Some dealers is the use of good people are not on the stainless steel magnet suction misunderstanding, to deceive consumers, so the price as high with expensive stainless steel.There are more than 100 kinds of stainless steel, and the characteristics and functions are different. General decoration, landscape, sculpture using austenitic stainless steel. Because of the low thermal conductivity of austenitic stainless steel, using it as a kettle, wok, rice cooker is not appropriate, will use a lot of energy, but also to extend the boiling water cooking time. Using ferritic stainless steel as a wok and rice cooker, not only has excellent corrosion resistance, but also its thermal conductivity is nearly half higher than that of austenitic stainless steel.
Q:Is badminton material good with carbon fiber or carbon fiber + resin? Five
HelloThese two rackets are a good choice for beginners, and the price is almost the same. In theory, of course, the resin + carbon fiber is better. Carbon fiber increases the hardness of the racket, while the resin increases the toughness of the racket. Therefore, this kind of racket is softer than the center pole, suits the defensive and the ball control type. However, 3363 people as a basic racket, is not on the resin have too many requirements, as mentioned above, the content of resin may be less than 5%, which is why the two price is almost the sake of racket.My suggestion is that the landlord to buy carbon fiber 3361, first, this time longer, very popular, reputation has been good, two is 3363, some people feel too soft, the ball is not far away, with a very uncomfortable feeling. Of course, it depends on the characteristics of the landlord himself.I hope that the answer can help to you, I hope you join our team "badminton kingdom", to create our own kingdom of badminton!
Q:What is the effect of carbon on the human body? One hundred
It is well known that the basic units of life, amino acids and nucleotides, are derived from carbon skeletons. First, a carbon chain, a chain of carbon bound together, evolved into proteins and nucleic acids; then evolved primitive single cells, evolved worms, fish, birds, animals, monkeys, orangutans, and even humans.
Q:Why is the solubility of carbon in austenite larger than that in ferrite?
Ferrite: interstitial solution of carbon formed in alpha Fe.Austenite: interstitial solid solution formed by carbon in gamma Fe.The ferrite structure is a BCC lattice with a gap radius (0.291~0.154). Because of the smaller size of the lattice gap, the solubility of carbon in alpha -Fe is relatively small.
Q:How to identify a laptop shell is carbon fiber
Carbon fiber, as its name suggests, is made from carbon fiber, so there are several characteristics. First, if it is not colored, you can see the obvious fiber. Second is black carbon color. And it's a lot more than ABS.
