摘要： A configuration in which particles of pitch 2 having a softening point in the range of 70 to 200° C. and a diameter equal to or smaller than 30 μm are held on the surfaces of particles of a refractory raw material 3 having a diameter equal to or smaller than 50 μm is employed. This pitch-containing refractory raw material 1 can be used with the pitch being in a fine-particle form without any aggregation even after the long-term storage. Using it as a part of a raw material formulation allows the fine particles of pitch to be uniformly dispersed during the mixing or kneading process. The resulting carbon-containing refractory has an excellent corrosion resistance. It also provides suppressed increase in the Young's modulus while maintaining the level of strength, thereby being excellent in thermal spalling resistance even with the carbon content ratio being low.

摘要： A nozzle for continuous casting of clean steel is capable of preventing adhesion of Al2O3-based inclusions to a wall surface of the inner hole of the nozzle while fully achieving an effect of a swirl vane. The swirl vane prevents drift in molten steel passing through the inner hole. The swirl vane is disposed in the inner hole. A wall surface is at least partly formed as a tubular-shaped refractory layer and is prepared by controlling a weight ratio of CaO/MgO and an apparent porosity to have a thickness of 3 to 20 mm, so as to prevent adhesion of Al2O3-based inclusions to the wall surface and the swirl vane while effectively maintaining the anti-drift effect for long hours. Further, inert gas is injected into a molten steel flow between an upper nozzle and the swirl vane to facilitate surfacing of Al2O3-based inclusions in a mold and reduce Al2O3-based inclusions in molten steel so as to achieve stable casting operation and high-quality steel with high cleanness.

The stacker stacks the sheet ejected from the ejection port, and the ejection space is disposed above the stacker. The fan is disposed outside the ejection space to suck air. The duct is connected to the fan. The duct has an exhaust port and a guide. The exhaust port is disposed above the ejection port and downstream from the ejection port in the ejection direction to exhaust the air from the exhaust port toward an upper face of the sheet in the ejection space. The guide connects the fan and the exhaust port to guide the air from the fan to the exhaust port.

摘要： In a carbon-containing refractory composed of a refractory aggregate, a carbon based raw material, and a carbon bond connecting between the refractory aggregate or the carbon based raw material, transition metal-containing nanoparticles having particle diameters of 1,000 nm or less and containing a transition metal are contained in the above-described carbon bond while being dispersed.

Therefore, a carbon-containing refractory exhibiting high thermal shock resistance, high abrasion resistance, and high corrosion resistance are provided.

摘要： The present invention provides a technique of applying a CaO-containing material to a nozzle unit for casting of aluminum-killed steel, in such a manner that the amount of large-size alumina inclusions in slabs can be reduced irrespective of nozzle type, such as single-part type or multi-part type. The amount of large-size alumina inclusions in slabs obtained using a single-part type or multi-part type nozzle unit, which has an inner hole to be used for pouring molten steel from a tundish to a mold therethrough and CaO-containing refractories applied to a surface of the inner hole, has a strong correlation with the entire surface area of the inner hole of the nozzle unit and the amount of CaO contained in the employed refractories. According to the present invention, 50% or more of the entire surface area of the inner hole of the nozzle unit is formed of refractories containing 20 mass % or more of CaO to allow the amount of large-size alumina inclusions to be reduced.

摘要： The present invention is a measuring method for detecting penetrant metal intruded in refractories having a conductive cover at a first wall and a nonconductive surface at a second wall and for measuring their thickness. At least one sensor head is used including a metal sensor with a first and second conductive coil for measuring distance between the sensor head and a conductive substance and a distance sensor for measuring distance between the sensor head and the refractories. The sensor head is disposed at a plurality of fixed positions close to the second wall to face the refractories and an alternating current is applied to the first coil to generate an eddy current in the conductive substance which faces the metal sensor. An induced voltage induced in the second coil by at least the eddy current is detected and a first distance is obtained between the sensor head and the conductive substance based on the detected induced voltage. The distance sensor measures a second distance between the sensor head and the second side wall at fixed positions and a third distance is obtained between the second side wall and the conductive substance. Also information is obtained about a relative position of the sensor head with respect to the molten metal vessel. A location and dimension of the penetrant metal and a thickness profile of the refractories is calculated based on the first, second and third distances and the relative position of the sensor head.

摘要： In a method of manufacturing amorphous metal ribbons by ejecting molten metal through a nozzle attached to a tundish onto a rapidly moving cooling body, the molten metal is suppled to the tundish by first pouring the molten metal from a ladle into an intermediate vessel and then by supplying the molten metal from the intermediate vessel to the tundish through a gas-lift pump. An apparatus for supplying molten metal to a tundish comprises an intermediate vessel adjacent to the tundish and a gas-lift pump to supply the molten metal from the intermediate vessel to the tundish. The molten metal is poured from a ladle into the intermediate vessel. The gas-lift pump has a pump proper that is placed over the intermediate vessel and tundish so that its inlet and outlet open in the intermediate vessel and tundish, respectively. Bubbles are suppled into the pump proper through its inlet.
