Abstract: The present invention provides an anti-seizure agent for hot steel working comprising: an inorganic component as a first component; sodium hydroxide as a second component; water-soluble resins and/or water-soluble surfactants as a third component; and water, wherein, to the mass of 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 Al 2 O 3 , SiO 2 , CaO, B 2 O 3 , K 2 O, and Na 2 O. This anti-seizure agent for hot steel working exhibits excellent wettability and surface firm-adherability to the steel; moreover, the coating layer formed after application solidly adheres to the steel and does not come off in the environment of both cold and hot working.

Abstract: PURPOSE:To reduce COD value by adding a primary ion of specific times the mol of H2O2 to effectively treat an oil matter contained in a circulating cooling water in iron and steel factories at the time of reducing the COD value by adding H2O2 into an oil containing waste water. CONSTITUTION:The oil containing waste water produced in a rolling mill is fed into a flocculating and settling vessel 18 through a waste water pipe 1 and after the solid matter in the waste water is removed (flocculation and settlement) with a high molecular flocculating agent fed from a feeding device 19, is filtered further in a secondary treating device and is reused as the cooling water. At this time, one part of the waste water is transferred to a water storage tank 3 by using a valve 2, the COD value in the waste water is measured with an organic carbon analyzer 4 and a ferrous sulfate solution from a feeding device 6 and H2O2 from a feeding device 9 are successively added into the waste water (ferrous ion of 0.5-2.0 times the mol of H2O2 is added). As a result, activated.OH (OH radical) is generated, the decomposition by oxidation and dehydrogenation proceeds and the value of COD is reduced.
