Abrasive materials form the backbone of grinding, cutting, polishing, and surface finishing in modern industry. Their durability and performance depend not only on manufacturing processes but also on the raw materials used. Chromium-containing abrasives stand out due to their hardness, wear resistance, and thermal stability.

Role of Chromium

Chromium (Cr) is typically used as chromium oxide (Cr₂O₃) or in high-chromium alloys.

  • Enhances hardness.

  • Provides high-temperature stability.

  • Improves oxidation and corrosion resistance.
    For this reason, chromium is widely used in high-performance grinding wheels, refractories, and metal cutting discs.

Production Processes

  1. Raw Material Preparation: Chromium oxide, alumina, silicon carbide, or zirconia are milled.

  2. Mixing and Binder Addition: Mixed with resins, clays, or other binders.

  3. Shaping: Pressed or molded into the desired form.

  4. Drying and Sintering: Fired at high temperatures to gain strength.

Equipment Used

In abrasive production, casting pallets are not directly used. Instead:

  • Molds are used for shaping.

  • Presses compact powders under high pressure.

  • Furnace plates (refractory pallets) carry the products during sintering.

  • Mixers and grinders ensure homogeneity.

Thus, instead of the traditional "casting pallet" used in metal foundries, abrasives rely on furnace pallets, refractory plates, and pressing tools.

Conclusion

Chromium-based abrasives play a crucial role in heavy industry, aerospace, and metalworking due to their hardness and durability. Their production does not involve casting pallets but rather specialized presses, molds, and refractory carriers to ensure high-quality manufacturing.
