  • Patent number: 8455408
    Abstract: A method of coating uses an anti-seizure agent for hot steel working that exhibits excellent wettability and surface film-adherability. The agent comprises: an inorganic component (first component); sodium hydroxide (second component); water-soluble resins and/or water-soluble surfactants (third component); and water. With the sum of the first component, the second component, and the third component as 100 mass %, the anti-seizure agent contains: 96.5 mass % or more and 99.98 mass % or less of the first component; 0.01 mass % or more and 2.0 mass % or less of the second component; and 0.01 mass % or more and 1.5 mass % or less of the third component, and the inorganic component is one or more selected from a group consisting of Al2O3, SiO2, CaO, B2O3, K2O, and Na2O. A coating layer formed solidly adheres to the steel and does not come off in both cold and hot working.

  • Patent number: 5681383
    Abstract: A surface-treating agent for a high-temperature refractory material, essentially consisting of 35.0 to 50.0 wt % of sodium silicate, 1.0 to 10.0 wt % of lithium compound, 1.0 to 10.0 wt % of alkali borate, 1 to 10.0 wt % of an organic silicone compound represented by the formula, R--Si(OH).sub.2 Na, wherein R stands for an alkyl group of 1 to 12 carbon atoms, and water and having a viscosity of not more than 100 cps at 20.degree. C., and a method for the surface treatment of a high-temperature refractory material, essentially consisting of rapidly spraying the treating agent mentioned above onto the surface of the refractory material when it is at a temperature in the range of 500.degree. to 1200.degree. C., thereby forming a layer of the treating agent in a molten state, and retaining the layer at a temperature of at least 1100.degree. C.
