Definitions

  • the second method, the cement gun, is only suitable for the temporary repairs of the exterior sections of the ovens.
  • an object of the invention is to develop such a product whose manufacture does not involve technological difficulties, is of low cost and does not require the use of substances which are costly, are difficult to be found or involve dangers for the workers or for the environment.
  • the function of the alkaline salts of silicic and/or metasilicic acid is of forming, at the surface of the refractory materials onto which the product is applied, a vitreous or ceramic layer having a high hardness.
  • This layer effec- tively protects the refractory material from the wear by abrasion, reduces the friction coefficient with respect to the coke, thus reducing the resistances when the coke is taken out of the oven, and is suitable for obstructing, and therefore repairing, at least the minor fissures.
  • the function of the fluxes is to render more easy and uniform the building up of said vitreous or ceramic layer, and the fluxes derived from boron also have the function of increasing the hardness of said vitreous or ceramic layer.
  • the function of the refining products is to suppress or reduce the dishomogeneity of the components in the building up of said vitreous or ceramic layer.
  • the refining products include sodium sulphate.
  • the alkaline salts of silicic and/or metasilicic acid are included in the product in a weight ratio from 30% to 60%, and more preferably from 45% to 60%.
