摘要： PURPOSE: To detect the amount of carbon contained in steel melt for easily and properly controlling decarburization, by measuring the amount of heat per time unit taken off with exhaust gas formed by injecting oxygen into the steel melt in a reactor vessel to refine said steel melt.
CONSTITUTION: Oxygen and Ar gases are injected through a tuyere 11 into steel melt 2 in a reactor vessel 1, while oxygen gas is blown through an upper lance 3 against the steel melt to perform its decarburization. An alloying element shooter 5 equipped with a cooling jacket is provided inside a suction hood 4 for discharging exhaust gas. The amount of heat per time unit in the exhaust gas which takes off heat formed by the oxidation of carbon in the steel melt 2 is measured from the difference ΔT in temp. between the inlet 51 and the outlet 52 of said jacket for circulating cooling water. Thus, the amount of carbon in the steel melt 2 is accurately estimated without depending on any analyzer means, accurate decarburization is performed, and the amount of carbon contained at a final point can be controlled.

摘要： PURPOSE:To elevate a dephosphorizing effect without dropping the yield of Fe, by blowing carbon powder and oxygen gas into molten steel under the existence of high basic slags, and bubbling molten slags so that they are discharged easily, when steel is manufactured and refined by an arc furnace. CONSTITUTION:When steel is refined by an arc furnace, high basicity slags whose basicity CaO/SiO2 is >=2 are generated by adding a flux such as CaO, CaF2, etc. Also, carbon powder is blown into molten steel together with oxygen gas by a lance, the carbon powder reacts with oxygen in the molten steel or the molten slag, and a great deal of gaseous CO is generated. By this gaseous CO, a foaming layer is formed in the molten slag and swells, its fluidity is elevated, and it is discharged easily out of the furnace. Accordingly, a phosphorous portion removed in the form of phosphoric acid lime in a high basic slag is discharged, is dephosphorized effectively without being rephosphorized in the molten steel, also the molten steel is oxidized at a high temperature, and the yield does not drop.

摘要： PROBLEM TO BE SOLVED: To obtain an antimicrobial wax which exhibits a persistent strong antimicrobial power and does not human bodies harm by dispersing, in a wax, an antimicrobial agent which is prepared by attaching silver and/or copper particles to the surfaces of ceramic particles. SOLUTION: This antimicrobial wax is prepared by dispersing, in a wax, an antimicrobial agent which is prepared by attaching 0.1-10 wt.% silver and/or copper particles having an average particle size lower than 4 nm to the surfaces of ceramic particles having an average particle size of 0.005-0.5 μm. The antimicrobial agent is prepared, e.g. by adding ammonia to an aqueous silver nitrate solution, dispersing the resultant silver nitrate-ammonia complex under stirring in an aqueous dispersion containing ceramic particles (e.g. titanium oxide particles) dispersed therein, adding a reducing agent (e.g. hydrazine) to the resultant dispersion to precipitate silver particles on the surfaces of the ceramic particles, and settling, separating, cleaning, and drying the ceramic particles having silver particles attached thereonto. Titanium oxide, silicon dioxide, felspar, zeolite, zinc oxide, zirconium oxide, calcium carbonate, etc., can be used as the ceramic particles.
