  • Method for partially building and/or repairing at high temperatures industrial facilities including a structure made of refractory materials, and prefabricated element therefor
    Patent number: 5966886
    Abstract: A method for repairing industrial facilities at high temperatures using at least one prefabricated element (1) made of mullite-crystallized refractory product with an alumina content of 30-80%, preferably 50-80%, made of refractory materials securely attached to the structure (11) of the facility by using an oxygen-containing carrier gas stream to spray a mixture of particles capable of exothermically reacting with the oxygen and particles of a refractory material, whereby a coherent refractory mass (14) is formed in situ for attaching said element to said structure.
    Type: Grant

  • Mixture of chemicals for forming a refractory composition
    Patent number: 5942453
    Abstract: A powdered mixture of chemicals for forming a refractory composition, including a filler consisting of refractory particles, metal particles and metal peroxide containing particles, wherein the metal peroxide containing particles have a calcium peroxide content of at most 75 wt %, a magnesium peroxide content of at most 30 wt %, a barium peroxide content of at most 92 wt %, and/or a strontium peroxide content of at most 90 wt %. A refractory composition prepared from said mixture, a method for forming said composition and a method for using same are also disclosed.

  • Method for partially building and/or repairing at high temperatures industrial facilities including a structure made of refractory materials, and prefabricated element therefor
    Patent number: 5833895
    Abstract: A method for repairing industrial facilities at high temperatures using at least one prefabricated element made of a -mullite-crystallized refractory product with an alumina content of 30-85%, preferably 50-80%, made of refractory materials securely attached to the structure of the facility by using an oxygen containing carrier gas stream to spray a mixture of particles capable of exothermically reacting with the oxygen and particles of a refractory material, whereby a coherent refractory mass is formed in situ for attaching said element to said structure.
