What is Graphite Crucible?
The graphite crucible is a kind of graphite mold, using as a carrier, which can put the raw materials and parts that we need to position or shape together in the graphite mold for high-temperature sintering, melting, or casting. The graphite crucible is made of artificial graphite blocks by mechanical processing.
High-purity graphite crucible has good thermal conductivity and high temperature resistance. In high temperature use, the coefficient of thermal expansion is small, and it has a certain resistance to rapid heat and cold. It has strong corrosion resistance to acid and alkali solvents and has good performance. The chemical stability. High-purity graphite crucibles have a wide range of applications, mainly used to smelt various silver, aluminum, lead, copper, zinc and other non-ferrous metals, medium carbon steel and rare metals. The high-purity graphite crucible has stable quality and long service life, greatly reduces fuel consumption, reduces labor intensity, improves labor intensity, and creates better economic benefits.
The advantages of graphite crucible are as follows:
In the metallurgical industry, high-purity graphite crucibles have a very wide range of uses. Its main function is to store various liquid metals. As a metallurgical manufacturer, graphite crucibles will be used. Otherwise, there will be some problems in the use and production. Let's introduce what issues should be paid attention to in the high-purity graphite crucible.
1. High-purity graphite crucibles are more susceptible to moisture, and the products will become soft after being damp, and some impact objects will be deformed when hit, and once water enters the high-purity graphite crucible, it will affect the inside. The raw materials in full bloom will cause the dilution of the raw materials, and some chemical reactions will further affect its quality problems, so waterproof measures must be done well.
2. Although the high-purity graphite crucible is very good in quality and not easy to damage, it should be handled with care. Dropping or bumping from a high altitude has little effect on the quality of the graphite crucible, but it will continue to do so for a long time. The phenomenon of cracks, there is no way to remedy this situation, it can only be replaced.
3. Do not heat the high-purity graphite crucible over an open flame. Because its thermal conductivity is not particularly sufficient, heating on it is meaningless, and it is unsightly if it is smoked and grilled or scorched underneath it.

Product Introduction
Brass smelting graphite crucible - an important tool in metallurgy. The crucible is made of high-quality graphite material and can be processed into two types: U-shaped and V-shaped according to customer requirements. Copper melting graphite crucible can withstand the extreme temperatures during the melting process of metallic copper. . Taking full advantage of the excellent thermal conductivity and stability of graphite materials, it is very suitable for metal copper smelting and heating applications.
ZIBO JINPENG Brass melting graphite crucible have adopted three kinds of materials:Fine-grain Specialty Graphite, High pure graphite, Isostaic graphite. They have different qualitative indicators, I will show up as following

Applications Of Brass Melting Graphite Crucible
Brass melting is an important process for various industries such as foundries and in the manufacturing of decorative items. To ensure that the melting process is efficient and effective, the use of graphite crucibles is essential. Graphite crucibles offer many benefits, including high thermal conductivity, resistance to thermal shock, and excellent chemical stability.
When using graphite crucibles for brass melting, it is important to ensure the crucible is clean and free from any contaminants that could compromise the quality of the melted brass. The crucible should also be preheated before its first use to prevent cracking or damage.
Once the crucible is prepared, the brass can be loaded into it and heated to the desired temperature. Graphite crucibles can withstand high temperatures, making them ideal for brass melting. The crucible should be handled with care during the heating process to avoid any damage or breakage, which could result in lost production time and increased costs.
As the brass melts, the graphite crucible helps to efficiently transfer heat to the material and allows the liquids to flow smoothly and pour easily. Graphite crucibles also have a low level of impurities, which helps to prevent oxidation and contamination during the melting process.
After the brass has been melted, the crucible should be allowed to cool before it is emptied. The crucible should then be carefully cleaned and inspected to ensure that it is ready for its next use.
Overall, the use of graphite crucibles for brass melting is a reliable and beneficial technique that can increase efficiency, improve product quality, and ultimately save time and money. With proper care and handling, graphite crucibles can be an indispensable tool for any industrial process requiring brass melting.
1. The crucible should be stocked in the dry situation
2. Carry the crucible lightly
3. Warm the crucible in the drying machine or near the furnace. The warming temperature should be up to 500&#;.
4. The crucible should be put under the furnace month flat.
5. When put the metal into the crucible, you should take the crucible capacity as your reference.If the crucible is too full,it will be damaged by expansion.
6. The clamps shape need as that of crucible. Avoid the concentrate stressed destroy of the crucible
7. Clean the crucible regularly and lightly.
8. The crucible should be put in the center of the furnace and leave some distance between the crucible and furnace.
9. Turn the crucible once in one week and this will help lengthen the service life.
10. The flame should not touch the crucible directly.
11. 24 hours constant use will make crucibles have longer service life.
The smelt soup in the crucible should be cleared out when the furnace stop working, in order to avoid molten soup solidificating and will be expanded when fire to reheat, and affect the service life of crucible or even burst.
12. We suggest that about 2 months for crucible melting aluminum alloy (every week for melting copper alloy), hanging out to check whether there is something wrong in the surface, and clean furnace hearth as well as turn the crucible, this operation ishelpful to prolong the service life of crucible.
