Magnesium Oxide Ceramic Crucible

The magnesium oxide ceramic crucible is made of high-purity MgO with a melting point of approximately 2800°C. It has strong resistance to alkaline slag and can be used in environments above 2200°C, suitable for smelting precious metals such as platinum and palladium, as well as special materials. Although it has poor thermal shock resistance and high cost, it is essential for high-end metallurgy and scientific research.

Advantages of Isostatically Pressed Crucibles:

  1. Energy-saving: Reduces energy consumption by 10-20%.
  2. Convenient use: Short preheating time, no need for furnace drying or sintering; can be directly powered for smelting.
  3. High efficiency: The furnace liner has high refractoriness; the inner bottom of the liner only needs to be pressed with one turn of induction coil at most. Compared with traditional ramming furnace linings, the furnace chamber has a larger volume and higher effective power, significantly improving the melting rate of the electric furnace.
  4. Quick installation and removal: Easy and fast to install and disassemble.
  5. Improved productivity: The assembly-based installation of the furnace liner greatly increases labor productivity and effectively reduces labor intensity.
  6. Enhanced molten steel quality: High refractoriness, good thermal stability, and strong resistance to high-temperature scouring by molten steel significantly reduce slag inclusions in molten steel.
  7. Long service life: Optimized particle gradation, high-performance composite materials, and pressure forming greatly improve the service life and stability of the furnace liner.
  8. Safe use: The ramming layer (safety lining) outside the furnace liner provides reliable protection when the liner fails, effectively preventing furnace penetration accidents.
