White Corundum Furnace (New)

White corundum Furnace

Equipment use description: Mainly used for electric fused corundum, mullite and other abrasives and refractory smelting.

Product Overview:​

  White corundum arc furnace is the main equipment for producing white corundum. The furnace body structure is unique, the shell is usually a circular platform, composed of U-shaped structure and slope structure, this design helps to reduce the area above the solution chamber, so that the heat is not easy to lose, so as to improve energy utilization efficiency.

Product features:​

  White corundum arc furnace has the characteristics and advantages of low energy consumption, high efficiency and safety, high degree of automation, continuous production, etc., which can meet the needs of large-scale industrial production.

Product process:

  1. Raw material preparation: Select high quality aluminum oxide powder as the main raw material, ‌ and add appropriate amount of conductive materials and additives ‌ as required
  2. Mixing of ingredients: aluminum oxide powder is mixed with conductive materials and ‌ additives in proportion to ensure the uniformity of raw materials ‌. ‌
  3. Loading: ‌ will mix the raw materials into the electric arc furnace, ‌ usually use tipping or fixed electric furnace.
  4. Power melting: Close the furnace cover, power so that the raw materials in the electric arc furnace began to melt. In this process, the aluminum oxide powder in the raw material is melted and recrystallized at high temperatures to form white corundum ‌
  5. Refining treatment: by controlling the parameters such as voltage, current and temperature in the smelting process, refining treatment is carried out to eliminate impurities and residual gases in the molten liquid to ensure the purity and quality of white corundum ‌
  6. Cooling crystallization: the molten liquid is poured into the ladle, cooled and crystallized at a certain cooling rate, and finally a dense white corundum block is obtained.
  7. Crushing and screening: the cooled white corundum block is broken, ‌ screening, ‌ according to the granularity required by customers for processing, ‌ to form different specifications of white corundum particles or micro-powder.
