Chelyabinsk Region, manufacture of refractory materials

Since 2009 VSM is applied to produce refractory materials (powders, mixtures, the so-called gunning mixes) and castable refractories. Such products are used in:

  • ferrous metallurgy;
  • non-ferrous metallurgy;
  • cement industry;
  • glass industry.

Experience of Russian producers suggests that application of VSM in production of refractory materials leads to complex improvement of quality and strength of final products.

The following effects can be observed during refractories formation and thermal coating application:

  • lower shrinkage stress;
  • zero cracking;
  • achievement of homogeneous mortar with no segregation effect;
  • - uniform distribution of single reinforcing fibers in the mix with no clumping.

After hardening refractories and the protective layer acquire the following properties:

  • higher impact strength help avoid damage risk to the product or thermal layer during transportation, erection or through occasional mechanical impact;
  • higher bending strength will ensure integrity of the layer during the start-up of the equipment (thermal expansion of metal);
  • during operation of high-temperature equipment: due to complete burn-out of polymer fiber at 350°C (mass fraction of ash is 0,035%) refractories are characterized by higher porosity.
