Copper

We continuously optimize the technical properties of our products to meet the increasing demands of this industry. Nowadays, equipment for this demanding industry is usually lined with magnesia-chromite bricks of our CRVV/CRXS product range.

Decades of experience in the non-ferrous metals industry enable us to explore new paths and to develop innovative refractory concepts and products for our customers. One good example is our CRVV/CRXS product range, which is performing extremely good for the copper industry.

Special Features of TRL Krosaki DBMC/RBMC Bricks:

  1. Access to the world’s best refractory grade raw material

  2. Low SiO2 Level ensuring direct bonding through Solid State Sintering at high temperature

  3. High temperature fired (~1800 Deg C) direct bonded bricks with low porosity and permeability ensured through automated mixer machine, hydraulic press and high temperature tunnel kiln

  4. Extensive direct bonding and special post firing treatment make DBMC bricks exceptional resistant to slag/molten metal attack

Solution for Secondary Copper Metallurgy

  • Mainly used for melting, refining & purifying red copper scrap

  • Copper products can be made according to different requirements such as copper rod, Copper ingot and Copper Cathode

  • Variety of energy sources are being used according to available facilities (Natural Gas, LPG, Heavy Oil, Diesel, Coal gas etc.)

  • High temperature resistance refractory bricks are used for long service life

  • These kinds of furnaces are mainly:

    1. Reverberatory (Square/Rectangular type furnace, Fixed/tilting)

    2. Short Rotary Furnace (Tilting, Cylindrical)

    3. TSL Furnace

    4. Induction furnace

Reverberatory / Rotary Furnace

High volume processing rate and low operating and maintenance costs.
Low metal recovery & higher fuel cost.

Factors Affecting the Life of Refractory

  • Metallic Oxide (Zn, Pb etc)
  • present in the slag
  • Copper oxide rich slag
  • Thermal Spalling
  • Metal penetration
  • Flame implementation oxy fuel burner

TRL Krosaki Offers tailored made solution for reverberatory furnaces in India that is Direct bonded brick & Castable concretes with different bonding systems.
