Product Description

single ring crucible

Graphite crucible, also known as molten copper clad, molten copper, etc., refers to a type of crucible made of graphite, clay,
silica and wax as raw materials. Graphite crucibles are mainly used for smelting non-ferrous metals such as copper, brass, gold,
silver, zinc and lead and their alloys.

single ring crucible

The graphite crucible is made of natural flake graphite as the main raw material, and is processed with plastic refractory clay or
carbon as the binder. It has the characteristics of high temperature resistance, strong thermal conductivity, good corrosion
resistance and long service life.

single ring crucible

In the process of high temperature use, the thermal expansion service coefficient is small, and it has certain strain resistance to rapid cooling and rapid heating. It has strong corrosion resistance to acidic and alkaline solutions, has excellent chemical stability, and does not participate in any chemical reaction during the smelting process. The inner wall of the graphite crucible is smooth, and the molten metal liquid is not easy to leak and adhere to the inner wall of the crucible, so that the metal liquid has good fluidity and pourability, and is suitable for casting and molding in various molds. Due to the above excellent characteristics of graphite crucibles, it is widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys.

Crucible Instructions

1. There are a certain amount of pores in the body of the graphite crucible, which is easy to be affected by moisture. It must be
baked and preheated before use, especially in the humid summer in the south. 2. The crucible is preheated and baked in the empty
tank without feeding 3. The crucible needs to be dried before preheating, otherwise the low temperature preheating time should be
prolonged 4. If the crucible is preheated too fast, it is easy to cause the crucible to burst. 5. The crucible is preheated above
400℃, the time should not be too long, if the time is too long, the fuel will be lost, and if the time is too long or too short,
the life of the crucible will be shortened. 6. The crucible heating rate is up to 400℃ 7. After the crucible is preheated, the
operator needs to quickly raise the temperature to about 950°C without feeding, and then bake the empty can at high temperature
for 0.5h to 1h. When the temperature drops to about 700°C, start feeding.

factory profile

ZOUPING SANJING CARBON CO.,LTD

Zouping Sanjing carbon Co., Ltd. was engaged in graphite industry in 1974, its predecessor was Shanshan Group sub-processing points, after more than 40 years of continuous development, has now developed into covering, graphite materials, refractory materials, metal materials, polymer materials and other production, research and development, sales as one of the comprehensive enterprises. At present, the company has set up branches in Shandong, Henan, Jiangxi and other places, and has agents in many
provinces across the country. The main plant Zouping Tricrystal Carbon Co., Ltd. covers an area of 100,000 square meters with a total investment of 370 million yuan. There are more than 300 employees, including 40 senior and middle engineers and technicians, and more than 100 people with bachelor's degree or above, covering the whole systematic service of graphite research and development, production, processing and sales.

Ordinary crucibles

In the early days, the manufacture of graphite crucibles was relatively imperfect. Some ordinary crucibles were gray in color, coarse in graphite particles, low in density, and contained impurities, which affected the quality and color of the metal during casting. Due to the low purity, it was easy to crack during high-temperature casting. Reduced use life.

High-purity graphite

Using selected smelting graphite as the main raw material, the purity is as high as 99.95%, and it is refined by the manufacturer. It has high density and will not be mixed with impurities during the smelting process. Used for refining high-purity precious metals.
