Graphite Crucible

Graphite crucible, also known as molten copper ladle, molten copper, etc., refers to a class of crucibles fired with graphite, clay, silica and waxy stone as raw materials. raphite crucibles are mainly used to melt non-ferrous metals and their alloys such as copper, brass, gold, silver, zinc and lead.

Description

Graphite crucible, also known as molten copper ladle, molten copper, etc., refers to a class of crucibles fired with graphite, clay, silica and waxy stone as raw materials. Graphite crucibles are mainly used to melt non-ferrous metals and their alloys such as copper, brass, gold, silver, zinc and lead. Graphite crucible is characterized by high temperature resistance, strong thermal conductivity, good corrosion resistance and long service life.

Graphite crucible is characterized by high temperature resistance, strong thermal conductivity, good corrosion resistance and long service life. In the process of high-temperature use, the coefficient of thermal expansion is small, and it has certain strain-resistant performance to rapid cold and heat. It has strong corrosion resistance to acidic and alkaline solution, excellent chemical stability, and does not participate in any chemical reaction in the melting process.

The inner wall of graphite crucible is smooth, the melted metal liquid is not easy to leak and adhere to the inner wall of the crucible, so that the metal liquid has good mobility and casting, and it is suitable for casting and molding in different kinds of molds.

Features

01
The high density of graphite crucible makes the crucible have the best thermal conductivity, and its thermal conductivity is obviously superior to other crucibles.
02
Graphite crucible has special glaze layer and dense molding material on the exterior, which greatly improves the corrosion resistance of the product and prolongs its service life.
03
The graphite composition in the graphite crucible is made of high quality graphite material with very good thermal conductivity. The graphite crucible must not be placed on a cold metal table immediately after heating to avoid it rupturing due to rapid cooling.

Care and Preservation

Graphite crucible should pay attention to moisture proof.Graphite crucible is most afraid of moisture, and the quality is greatly affected by moisture. If using the crucible with moisture, there will be phenomena such as rupture, bursting piece, dropping gang and dropping bottom etc., which will cause the loss of melted metal, and even industrial accidents. So the graphite crucible must pay attention to the moisture proof in the process of storage and use.
