Unshaped refrectories for lining

Scope and purpose

Production of refractory products and monolithic lining of heat generating units in various industries. Refractory concrete and ramming materials are used as unformed materials for lining.

Characteristics of Refractory Concrete

Are made according to TU 1584-003-43539424-2018

Application area, Material grade

  • lids for blasting – annealing furnaces VulCAST 45R, VulCAST 60R, VulCAST 65R
  • steel ladle covers – intermediate reinforcement lining – ladle leveling layer – hearths of VulCAST 60R heating furnaces VulCAST 65R
  • heating wells – boilers VulCAST 45 R
  • gutter cover VulCAST 45R, VulCAST 60R, VulCAST 65R
  • blast chutes – bottom and walls of cast iron ladles – cupolas VulCAST 70R
  • working lining of the bottom and walls of the steel ladle VulCAST 87L, VulCAST 91L, VulCAST 95L
  • lining of the nozzle of the VulCAST 91 L, vacuum unit VulCAST 95 L
  • manufacture of refractory products for steel pouring ladles (purge systems, nest blocks, bucket glasses, etc.) VulCAST 96 U

Benefits of Refractory Concrete

  • mechanization of the lining process and a significant reduction in labor costs;
  • easy way to use;
  • high durability during operation;
  • the use of a special vibration pattern for workability of the working layer of the linings

Characteristics of ramming masses

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

VulTamp® 90 F corundum stuffing 90% to 1750
VulTamp® 93F 93%

The benefits of ramming

  • 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.
