    Metal smelting industry

    Metal smelting is the process of changing metal from combined state to free state. The reduction reaction of carbon, carbon monoxide, hydrogen and other reducing agents with metal oxides at high temperature can obtain metal elements.
  • One-ring high purity graphite crucible for melting precious metals

    One-ring high purity graphite crucible for melting precious metals

    The precious metal smelting is divided into roughing and refining. High purity precious metals are obtained by smelting low purity precious metals. The graphite crucible used in refining need high requirement to the purity, bulk density, porosity, strength and other indicators. The material is isostatic pressure or molded graphite with three dipping and four baking. The processing requirements are very strict, not only the size of accurate, but also the surface polishing. Our graphite material is strictly tested and carefully selected to ensure that it can matched with the power, the heating effect is the best, and the processing technology must meet the design requirements.

  • Graphite crucible with thread lid

    Graphite crucible with thread lid

    This product adopts high purity, high density, high strength isostatic pressure graphite material, its purity is very high and will not have pollution to the metal it will hold. With its unique threaded sealing cover design, it has good sealing performance, assure the metal liquid will not leak out.
  • High Purity Isostatic pressing formed graphite Crucible

    High Purity Isostatic pressing formed graphite Crucible

    Isostatic Pressing Graphite has good heat resistance. In inert gas, its mechanical strength increases with the increase of temperature, reaching the peak value at about 2500℃.Compared with ordinary graphite, the structure of isostatic graphite is more compact, delicate, and symmetrical. It's thermal expansion coefficient is very low, its thermal shock resistance is excellent, and its isotropic, chemical corrosion resistance is strong, meanwhile, it has good thermal and electrical conductivity and excellent machining performance.
  • Isostatic pressing crucible for aluminum evaporation

    Isostatic pressing crucible for aluminum evaporation

    Aluminum foil for packaging, decoration (gold and silver) and electrical equipment (capacitor) has a wide range of applications. This process is made by evaporating molten aluminum in high temperature and high vacuum to make it evaporate on plastic film or paper.
  • Crucible with thick wall

    Crucible with thick wall

    Crucible with thick wall is made of high-purity graphite as the main raw material It has the characteristics of 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 a certain anti strain performance for rapid cooling and rapid heating. It has strong corrosion resistance to acidic and alkaline solutions, excellent chemical stability, and does not participate in any chemical reaction in the smelting process. The inner and outer walls of the graphite crucible are polished to make the appearance smooth. 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 castability. It is suitable for casting in various molds. Due to the above excellent characteristics of graphite crucible, high purity graphite crucible is widely used in smelting alloy tool steel and nonfe

  • Graphite crucible for aluminized film production

    Graphite crucible for aluminized film production

    Graphite crucible is a consumable part widely used in the production of vacuum aluminized films. The quality of graphite crucible will directly affect the quality and production cost of aluminized films. The quality requirement to graphite crucible in vacuum aluminizing production is very strict, at present, there are few enterprises that can produce and supply this kind of crucible stably. According to the process requirements of vacuum aluminum plating, we choose special graphite as material, which has high bulk density and low porosity, and can resist the erosion of molten aluminum and gaseous aluminum particles to the greatest extent. The graphite material is treated by special technology, which leads to strong oxidation resistance, low consumption and long service life.
