    摘要: In a insert-type continuous casting nozzle comprising a highly functional layer formed to have a high corrosion resistance, a high anti-attachment capability, etc., and provided to define an inner bore thereof, the present invention is directed to providing a refractory material (mortar) for an intermediate layer of the continuous casting nozzle, which has a property capable of fixing an inner bore-side layer to an outer periphery-side layer (a nozzle body) of the continuous casting nozzle, while preventing the occurrence of expansion splitting in the outer periphery-side layer due to a difference in thermal expansion between the inner bore-side and outer periphery-side layers, and a continuous casting nozzle using the refractory material for the intermediate layer. The refractory material for the intermediate layer contains a hollow refractory aggregate in an amount of 10 to 75 volume %, wherein a ratio of an average radius R of each particle of the aggregate to an average wall thickness t of the particle satisfies the following relation: R/t≧10. This refractory material is disposed between an inner bore-side layer (2) and an outer periphery-side layer (3, 4) of a continuous casting nozzle.

    摘要: An RTC, having a crystal oscillator of different characteristics from those of a crystal oscillator, is provided, and the pulse period of the pulse signal from the RTC and the pulse signal based on the crystal oscillator are compared to detect a fault in the crystal oscillator. As a result, even if, for example, located in a high temperature environment, the degrees to the decrease in frequency will be different, thus making it possible to detect reliably a fault in the crystal oscillator.

    摘要: A production management system has processing devices A, B, C, D, E, and P. A kind of product α is processed in the order of the processing devices A, P, B, P, and C, and a kind of product β is processed in the order of the processing devices D, P, E, and P. To determine whether the processing device P is to be used to produce the product α or the product β, an input ratio of each kind of product is multiplied by the number of times of passing the processing device P for each kind of product, thereby calculating a core of each kind of product. Based on the calculated score, whether the processing device P is to be used to produce the product α or the product β is determined. Accordingly, the work-in-process balance of key processes between different kinds of products can be equalized.

    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.

    摘要: A casting apparatus for low-melting metals has a coating layer of two-layered structure which hardly reacts with low-melting metals, adheres firmly to the substrate, and protects the substrate from thermal and mechanical shocks for a long period of time. The layer in contact with the substrate contains glass powder having a melting point below 1000.degree. C. and at least one binder selected from silicates and phosphates. The layer in contact with molten metal contains 5-80 wt. % of at least one fluorine compound (as a corrosion resistant material) having a melting point of above 700.degree. C. Owing to the multiple layers, each having a specialized function, the casting apparatus has improved durability over a long period of time.

    摘要: A system for transmission of signals between modules wherein, for example, it is possible to transmit reliably, between modules, information relating to, for example, the actuation of safety devices. A transmission module for transmitting a pulse signal of a specific period, which indicates the existence of information, generates, in time division, pulse signals by a plurality of signal generating units that are provided in parallel, and then combines these pulse signals into a single time series pulse signal. Then an attempt is made to output this pulse signal towards a receiving-side module through a relay for controlling the output, and the signals appearing at a normally-open terminal and at a normally-closed terminal of the relay are monitored to determine whether or not there is a failure, where the generation of the pulse signal is stopped when a failure is detected.
