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.

Q:What is the importance of carbon graphite as biological material?
As one of the main uses of refractory graphite is the production of refractory materials, including refractory brick, crucible continuous casting, casting mold, mold powder, detergent and high temperature resistant materials by graphite crucible and crucible forming manufacturing related products and refractory and related products, such as crucible, retort, plug head and nozzle etc., has high fire resistance, low thermal expansion, metal smelting process, by metal infiltration and erosion are stable under high temperature, good thermal shock resistance and excellent thermal conductivity, so the graphite crucible and its related products are widely used in the process of direct molten metal.
Q:Can magnesia crucible be melted into stainless steel?
In the smelting of titanium alloy, because there are a lot of active element Ti in the alloy, it is easy to react with C, N, O and other elements, resulting in the change of alloy composition
Q:Aluminum graphite crucible for iron crucible which is good
The graphite crucible produced by our factory can live for 6-9 months.
Q:What are the carbon elements? What are their structures? What are their properties and uses?
C60 molecule is a molecule made up of 60 carbon atoms. It is similar to football, so it is also called "football"C60 is a stable molecule formed solely by carbon atoms. It has 60 vertices and 32 faces, of which 12 are pentagonal and 20 are regular hexagons. The relative molecular weight is about 720.
Q:Can the silicon carbide bearing in the canned motor pump be replaced by graphite bearing? How big is the difference?
Mainly depends on what medium you use Not strong corrosive medium, such as structure, interchangeable, wear-resistant SiC bearings are mainly used in low viscosity and high corrosive medium, but also has its shortcomings, afraid to bump
Q:When decomposing iron ore, why should it be carried out at low temperature?
The decomposition of iron ore, in practical applications, is based on the characteristics of the ores, the requirements of the analytical items, and the separation of interfering elements. Acid decomposition and alkali melting are usually employed.
Q:Will a graphite crucible conduct electricity?Soluble aluminum material with electric iron stove appearance
Chemical stability: graphite has good chemical stability at room temperature. It can resist acid, alkali and organic solvent
Q:Does the graphite pan need preheating?
5. the use of coke block size is less than the furnace wall and the crucible spacing should be added since the 5 fall, not ramming.6. crucible before use for 1-1.5 hours from the gas warm up to 200 degrees Celsius (especially in the initial drying must be in a continuous turning of the crucible and the crucible, slowly warming up and down at the same time and shall not exceed 100 degrees, to be slightly cooler, water vapor discharged after 1 hours) and then continue to heat up. The temperature to about 800 DEG C, baking time not too long. (such as spalling, improper preheating burst, not a quality problem, if the company is not responsible for the return. 7.) must keep the inside wall intact, to avoid bias by.8. flame burner flame heating, don't direct injection in the crucible, should be sprayed on the seat and into the crucible.9. proposed to use.10. into the metal crucible clamp corresponding to the bottom and then insert the scrap metal ingot, but not too close to the edge and, in order to avoid fragmentation through the use of a.11. crucible crucible best due to the expansion of metal Continuous melting, reduce the interval time.12. if intermediate stop using the remaining liquid should be dry, in order to avoid cracking caused by the continued use of.13. in the smelting process, must strictly control the amount of refining agent, added in excess, will reduce the service life of the crucible. And often clean ballast junction, guide and capacity to change the face of the impact of free crucible at the same time. Ballast too thick will cause the upper expansion.
Q:How to extract pure silver from sundry Silver
The precipitation of silver chloride solution: according to the volume of silver nitrate, and then added according to the volume ratio of about l% concentration of 16% hydrochloric acid, the production of white silver chloride precipitate. For clarification, pumping liquid holding, will precipitate wash with water 2 to 3 times, to reach the neutral.
Q:How is graphite formed?
1 isostatic pressed graphite. That's what a lot of people call "three high" graphite, but not three highs or equal pressure.2, molded graphite
