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

Q:How to select and use the carbon graphite for machinery? What items should we pay attention to?
In the case of high or high pressure, heat of friction must be derived by an effective method and should be washed when used in a crystalline medium.
Q:The graphite boat loading and loading real real graphite boat is what?
The graphite boat used for solar energy industry and real loading: PECVD carrying vehicles, loaded from silicon, preparation of middle and high efficiency filter, ensure that blows air purifying requirements.
Q:Why do laboratory crucibles use ceramics instead of glass?
Because the glass has a softening temperature, and the temperature is below 1000 DEG C, therefore, made of glass crucible at high temperature when the heating crucible may be softening deformation, and the glass crucible should not contact with alkaline substances.
Q:How to judge the thermal stability of rubber oil?
Thermal analysis method of qualitative thermal stability of 1 instrument 1.1 instrument differential thermal analyzer (DTA) and differential scanning calorimeter (DSC), temperature programmed rate at 2~30 C / min range, the precision of temperature control for soil 2 degrees, the size of power difference or temperature difference can reach 40% ~ 95% of the full scale deviation on the recorder.
Q:What is the difference between the indirect method Zinc Oxide and the direct law Zinc Oxide?
Zinc Oxide direct method generally used for ceramics, glaze, glass frit, and pigment industry.Zinc Oxide: the indirect method can be used in rubber, varistors, paint, phosphating solution, film, conductive materials and other industries. The direct effect of heavy metal impurity content of the products of the heavy metal content of zinc or zinc, low heavy metal content of the products, but also can be used for livestock feed, medicine, health care and other industries.
Q:Which is a good quality graphite crucible?
The silicon carbide crucible is a bowl shaped container with a ceramic bottom. When solids have to be heated by fire, the crucible must be used. Because it is more able to withstand high temperatures than glass. When used, the crucible does not usually fill the melt too much to prevent the heat from jumping out and allowing the air to pass in and out freely for possible oxidation.
Q:I'd like to smelt 104 aluminium alloy by medium frequency furnace. What should I pay attention to? Please point it out, thank you!
I can not decide which is good. I just want to talk about the smelting methods of some nonferrous alloys of my own experience. (1) casting, casting, tin bronze, 5-5-5, fused magnesia, medium frequency furnace smelting. Carbon contamination of aluminum alloy and copper alloy
Q:How to calculate the loss of aluminum slag melting?
Look at the size of aluminum slag, big saw recovery rate is high, small saw fine chip is low.
Q:What are the characteristics of jade? There are jade and jade on the market. How do you distinguish it from jade?
The first is to make amorphous jade glass material. The reagent and reagent of sodium aluminum silicate and silicate containing colouring ions, according to the composition of jadeite content, is placed in a crucible into the mixing and grinding after the vessel, and then placed in a muffle furnace crucible is heated to 1100 degrees Celsius, and constant temperature cooling after a few hours, they can get colored amorphous glass material the composition of jadeite jade. The second is made of crystal jade glass. The amorphous glass will jade colored pieces to more than 125 meshes (i.e. particle size less than 0.125 mm), 600 kg / cm on the embedded prototype, heating prefabricated 14X15 (mm) cylinder or 14X6 (mm) of the wafer; then the preformed cylinder or wafer in high-purity graphite crucible. Bake in the oven at 140 degrees Celsius for 24 hours or more; and then the pressure chamber six crucible into a compressor, the compressor start six top closure, in the long time, current power, pressure relief, can get the crystal jade glass. Synthetic emerald glass by X ray powder diffraction analysis, infrared absorption spectrum analysis, chemical composition analysis, hardness measurement, relative density (specific gravity), determination of refractive index determination, fluorescence analysis, and the data are basically consistent with natural jade.
Q:What material of graphite is used in arc furnace production?
Today, large diameter semi graphitic carbon electrodes have been adopted in industrial silicon electric furnaces. Can effectively save production costs, and the technology is relatively mature.
