Products Description

SiC Graphite Crucible-- High Temperature Resistant Molten Copper Aluminum Casting

What we used is high purity, three high ,fine grain graphite material, (moulded through big press machine, the graphite will be pressed more compact,lower porosity rate,so the oxidation resistance will be better).

Our crucible moulds are made of quality graphite, with good thermal conductivity, which can well shorten the melting time and save energy, can withstand 2000 degree Celsius, resistant to corrosion and compression, flexible and durable, not easy to break or deform, can serve you for long time.

Products features

(1).Graphite crucibles have been a popular choice for melting and casting metals due to their excellent heat stability and thermal shock resistance. But with the increasing demand for better performance and durability under extreme conditions, SiC graphite crucibles are becoming more common in various industries such as metallurgy, foundry, and semiconductor.

 

(2).SiC graphite crucibles are composed of high-quality graphite and silicon carbide, which forms a dense and strong material that can withstand high temperatures and thermal shocks. This combination provides the crucible with enhanced properties such as excellent thermal conductivity, high corrosion resistance, and low ash content. These properties make SiC graphite crucibles an essential tool for melting and casting metals in various industries.2-1

 

(3).One of the significant benefits of using SiC graphite crucibles is their superior heat resistance. These crucibles can withstand temperatures up to 1800°C without any deformations, making them ideal for high-temperature applications. They also have a higher thermal conductivity compared to standard graphite crucibles, which aids in faster melting times and saves energy.
In addition to their enhanced heat resistance, SiC graphite crucibles also have excellent corrosion resistance. They can resist acid and alkali solutions and the aggressive environments that occur during certain metal melting processes. This property makes the crucibles highly durable and long-lasting, lowering the overall cost of ownership.

 

(4).Furthermore, SiC graphite crucibles have significantly lower ash content, which is critical in applications that require clean and pure metal alloys. This feature prevents the precious metals from being polluted during the melting process, ensuring high-quality output.

 

(5).Finally, SiC graphite crucibles require only minimal maintenance, making them a cost-effective option in the long run. They are easy to clean, require no preheating, and have a longer lifespan than standard graphite crucibles.

 

In summary, SiC graphite crucibles are an ideal choice for high-temperature melting and casting applications. Their superior performance, enhanced durability, and low maintenance requirements make them a valuable tool in various industries. Whether you are working with precious metals or other high-temperature materials, SiC graphite crucibles provide the reliability you need for consistent and high-quality output.

HOW TO WON FOR BEST PERFORMANCE
During the use of the crucible, if the following matters can be followed, the best performance of theintained and the service life of the crucible can be effectively extended.
1. For different melting metals, crucible for corresponding design purposes should be selected.3-2

 

2. When heating the crucible, note the following:

   (1). Preheat the new crucible as specified to remove moisture in the crucible.
   (2). Heat the outer surface of the crucible evenly when heated.
   (3). Use the crucible furnace cover to seal the top of the crucible to reduce heat loss and oxidation of the crucible. But leave enough expansion space to avoid pressing tightly along the crucible.
   (4). When using a gas or fuel crucible furnace, use a slightly oxidized flame and avoid direct flame injection at the bottom of the crucible.
   (5). When adding additives, the metal solution should be stirred immediately and the slag on the crucible should be removed in time. When adding flake or bulk additives, use a bell cover to immerse them.
 
3. In the pouring process, avoid crucible clamp, ladle and other tools collision or knock crucible.
 
4. When cleaning the crucible, use special tools matching the crucible to clean while it is hot.
 
5. When the crucible is temporarily suspended, the following matters shall be noted:
   (1).If gas or gas-burning furnace is used, all fans should be closed so as not to cause oxidation or even rupture caused by cold air invading the outside of the crucible.
   (2).Make the crucible self-cooled to room temperature. accelerating or delaying the rate of self-cooling may increase the oxidation of the crucible or lead to the rupture of the crucible.
   (3).For the crucible which is not often used, it should be stored in a fixed area and keep the storage environment dry.
 
6. The use condition of crucible furnace should be checked frequently to ensure that the crucible furnace works normally. The slag on the inner lining of the crucible furnace should be cleaned in time.
 
7. lf the customer stops the furnace for more than 3 days, it is necessary to re-bake the crucible as if using a new crucible. lf the weather humidity is too high, the furnace body and crucible must be seriously dampened, must first put the crucible baking furnace body for 2 hours, and then put the crucible into the furnace body to bake again like a new crucible.
