ALUMINIUM INDUSTRY (Al-wetting products)

Manufacturer of trading product by our firm plays key role in developing materials of aluminium industry. We offer castables, bricks, and additional products for the lining of every type of furnace, runner and ladle.

Advantages of using monolithic linings in aluminium furnaces:

  • Essentially fewer joint compared to the brick execution
  • The furnace geometry can be formed more flexibly
  • Partial repairs are possible
  • Cleaning is easier because the bricks cannot be pulled out
  • Due to high density of castables and their non-wetting effect
    • the work lining seems to have essentially less damp effect
    • compared to brick execution, lower inclination seems to the formation of corundum
    • Lower maintenance cost due to the longer lifetime of refractory lining
    • Better quality of the aluminium alloys because of no Si dissolving in the binding phase

Monolithic products:

  • LC and MC castables, where the aluminium touches the lining
    (work lining)
  • Insulating castables and castables of safety layer
    (also Al-wetting)
  • Drying masses
    (Induction furnaces)
  • Plastic masses
    (Induction furnaces, burners, repairing masses)
  • Special masses for different fields of application: castables on SiC and SiO2 basis
    (Charging bank, areas requiring good thermal-sock resistance)

Fields of application:

  • Aluminium melting furnaces, picture 1 and 2.
  • Melting and holding shaft furnace picture 3 and 4.
    (E.g. ZPF-Therm, Striko, Stotek, etc.)
  • Low-pressure furnace, picture 5.
    (E.g. Westomat, Stotec)
  • Induction furnace, picture 6.
    (E.g. Junker, Inductoterm)
  • Induction furnace with runner, picture 7.
  • Ladles, public road transport ladles, runners

Induction furnaces with crucible

Among our producers there is one of the world’s leader suppliers of refractory foundry materials. Its Unique Swedish basic commodity has been a benchmark to other induction furnace lining materials since more than 50 years. We offer all types of dry vibro-mass: acid, neutral, basic. Wilde range of our dry masses has been used for 40 years in induction furnaces for melting iron, steel and copper. The basic product line enables to found compound steel, high manganese content manganese steel mainly continuous works. For melting copper and copper alloy we offer different products.

Melting furnaces with runner, holding and casting furnaces

As a result of the close cooperation with furnace manufacturers and foundries, a wide choice of quality materials and solutions have worked up for moulders. Refractory liners are excellently applicable even in the most employed areas. Neutral and basic materials are available for the inductor.

Cupola furnaces

As a market leader, our producer transports high quality materials for the long, medium and short campaign cupola furnaces. Lining materials let users get several advantages:

  • Increased walling lifetime
  • Reduced production losses
  • Efficient, productive lining materials
  • Reduced maintenance time
  • Lower power consumption
  • Prominently good repairing and walling methods

However, ladles play key role in every foundry. We take great care of the choice of the necessary refractory liners for every possible ladle to reduce heat loss and consumed energy.

Lining in ladles can be done with castable, fireclay and basic bricks depending on the application.

    1. Non-ferrous metal foundry
  1. Cement Intusdry

Due to developments made for the past 30 years, our partners possess a wide product palette adequate for the requirements of cement industrial refractory materials.

In our product palette you can find:

  • LC low cement castables
    outstanding strength, resistance to wear and corrosion
  • ULC – ultra low cement castables
    lowest porosity; excellent mechanical resistance to wear, and resistant to alkali formation
  • Self-flowing castables
    for the lining of thin layers and hardly accessible places, with keeping the quality of LC and ULC castables
  • Gunning castables, masses
    low installation loss, equal homogeneity
  • Rammed castables
    easy installing, and drying combined with good strength and thermal-sock resistance
  • Special LC and ULC castables enriched with SiC
    resistance to the corrosion in consequence of alkali, respectively to eliminate or minimize sticking up
  • Plastic refractory materials
    air setting or phosphate setting working lining for some special area
  • Insulating castables
    casting or gunning with low installation loss

Fields of use:

  • Clinker cooler
  • Satellite cooler – outlet, knee
  • Burner/lance
  • Rotating kiln – closing ring
  • Furnace head
  • Tertiary air pipe
  • Chain zone
  • Grate
  • Inlet part
  • Cyclones
  • Chutes
  • Cooler – air exhauster cyclones

    2. Ramming and self-flowing castables
      1. Ramming castables
        (Easy to install, requires minimal vibration.)
      2. Self-flowing castables
        (Requires precise mixing, but it does not have to be vibrated. It fills in the space and exhausts air by itself. It casts very well to the cleaned old lining.)
    3. Gunning masses

  2. Plastic ramming masses
    They are installed by ramming. It makes the lining of roofs and vaults possible. It is easy to dry and it has remarkably good heat-sock resistance.

  3. Thin layers, top layers
    SiC products were developped for the refractory lining of diaphragm (membrane) walls. Among their qualities there are good thermal conductivity, good heat-sock resistance and chemical resistance.

  4. Insulating materials
    Their temperature of application is 850-1700 oC.

    Fields of application:

    • Outlet port
    • Fluid beds
    • Cyclones
    • Slag conductor
    • Burners
    • Furnace chamber
    • Inlet part

  1. Waste Incinerator

Our producers are suppliers of many companies that operate in the field of refuse destruction.

  • Household incinerator
  • Thick-walled grated incinerator
  • Thin-walled grated or rolling incinerator
  • Static or circulating fluid-bed incinerator
  • Vibrating or rotary kiln incinerator
  • Incinerator with pyrolysis
  • Hospital incinerator
  • Industrial suspension incinerator
  • Biomass and wooden cuttings incinerator

Our refractory products meet the requirements caused by the resistance to corrosion and abrasion, aiming at long-lasting usability.

Abrasion:
The inlet part, the sidewalls of the grate, and the slug tundish are places exposed to abrasion so much – it is recommended to install materials with low cement content.

Corrosion:
The ultra low cement castables and self-flowing castables are extensively used in chambers that claim alkali resistance.
