摘要： A method of producing an ultra-low-carbon steel by conducting vacuum-decarburization of a molten steel by means of a vacuum degasifier of the type having recirculation pipes and a vacuum chamber. When the carbon content of the molten steel has come down to a level of 50 ppm or less, hydrogen gas is introduced together with an inert gas into the molten steel either by directly injecting a hydrogen-containing gas into the molten steel in the vacuum chamber through a tuyere provided in the wall of the vacuum chamber or by blowing the hydrogen-containing gas onto the surface of the molten steel in the vacuum chamber through a lance provided in the vacuum chamber. In order to enhance the effect produced by the method of the present invention, it is possible to take an additional measure such as blowing of hydrogen gas through a tuyere provided in the wall of the recirculation pipe or injection of hydrogen or hydrogen-containing gas through an injection lance immersed in the molten steel held in, a ladle.

摘要： A method of producing an ultra-low-carbon steel by using a vacuum degasser on a molten steel has the steps of conducting vacuum decarburization to attain a predetermined level of carbon content, e.g., 25 ppm or below, in the molten steel while progressively reducing the pressure in said vacuum degasser, conducting addition of hydrogen in which hydrogen is dissolved in said molten steel while said pressure is temporarily elevated to 20 Torr or above, and conducting final decarburization after reducing said pressure to 2 Torr or below. The addition of hydrogen may be conducted to meet the following conditions:[H].gtoreq.{([C]-[C]final)/5}+4wherein [H] represents the hydrogen content (ppm) in said molten steel in the state after the addition of hydrogen, [C] represents the carbon content (ppm) in the molten steel in the state after the addition of hydrogen, and [C] final represents the final carbon content (ppm) to be obtained.

摘要： Method and top blowing lance for decarburization refining chromium molten ferrous metal in which dust formation and chromium loss due to oxidation are suppressed and high productivity is achieved. Decarburization of molten ferrous metal is achieved by blowing gaseous oxygen into the molten metal in a refining furnace provided with a top blowing lance having a plurality of gas blowing nozzles at the tip of the lance. The gas blowing nozzles include at least one sub-nozzle provided at or near the lance axis and a plurality of main nozzles at an outer section of the lance. Blowing refining is carried out with oxygen flow from a plurality of the main nozzles at a flow rate higher than that from the sub-nozzle(s), when the carbon content in the molten metal is about 1 wt % or more.

摘要： In this invention, the smelting reduction operation can be carried out in a high efficiency by charging a carbonaceous material in such an amount that total surface area is not less than 60 m.sup.2 per 1 ton of slag weight. Carbon substance finely particulating through thermal crumbling under a high-temperature atmosphere inside the vessel is used as the carbonaceous material, whereby it is possible to stably conduct the smelting reduction while controlling the scattering of the carbonaceous material, and also the erosion, particularly locally erosion of refractory in the smelting reduction furnace, which was a serious problem in the conventional technique, can considerably be decreased to largely prolong the service life of refractory.

摘要： A user terminal is connected through the Internet to a server. On the basis of the identification information of the client inputted from the client terminal, the server extracts an service selected by the client from a database for user management, further, extracts calculated maintenance contents for each service from a database for service management and sends them to the user terminal. Thus, the user can collect maintenance contents, such as the staff capable of providing service, the time until the user receives a service, and the charge, so that the user can utilize the information as indications to select an optimal service such as maintenance.

摘要： In an image reading apparatus, a white reference member for obtaining a reference value used in shading correction in the reading mechanism and an elastic member for cleaning a surface of the transparent member are provided such that respective positions of the white reference member and the elastic member with respect to the transparent member are variable. A controller controls the positions of these members with respect to the transparent member to alternately achieve movement of the white reference member to a position where the white reference member faces the transparent member and movement of the elastic member to a position where the elastic member faces the transparent member. The controller calculates the above reference value using a plurality of detection values read by the reading mechanism through the above positional control.
