Ramming mass

Scope and purpose

Ramming mass is a refractory material used for the manufacture of linings for thermal units of ferrous and non-ferrous metallurgy and other industries.


It is made according to TU 1523-011-43539424-2017

Application area, Material grade:

  • Vaults for electric furnaces – VulTamp® 87 F steel bucket nest blocks
  • cast iron and steel smelting furnaces – bottom and walls of casting ladles – bronze smelting furnaces VulTamp® 87 F VulTamp® 90 F VulTamp® 93F
  • VulTamp® 90 F aluminum smelting furnaces VulTamp® 93F

Basic indicators

Physicochemical properties:

Material grade, Mass characteristic, Сomposition mass fraction of Al2O3, Service temperature

VulTamp® 87 F, mullite-corundum stuffing, 87%, up to 1600 оС

VulTamp® 90 F, corundum stuffing, 90%, up to 1750 оС

VulTamp® 93F, 93%


  • increased ductility;
  • do not require high-temperature drying and firing;
  • developed on the basis of specially selected raw materials of high purity (corundum and Al2O3 compounds);
  • they are neutral; they are used for lining induction furnaces when melting high alloyed, manganese, and heat resistant steels;
  • form a particularly strong sintered surface at high temperatures due to thermally reactive components;
  • provide increased resistance to particularly aggressive metals and slag.
