摘要： PROBLEM TO BE SOLVED: To realize a method for evaluating the physical properties of a regular shape refractory product composed of more than one kind of material having different thermal conductivity nondestructively and accurately by heating the refractory product up to a predetermined inspection temperature and making an evaluation based on the temperature distribution shown by a thermographic image. SOLUTION: A thermography performs noncontact measurement of infrared energy radiated from a regular shape refractories to determine the infrared intensity distribution, i.e., the temperature distribution, imagewise. Obtained data is delivered to a data processing section in order to evaluate the physical properties of the regular shape refractories. Since the infrared wavelength region to be observed can be limited, reliability of measurement can be enhanced and since the data can be preserved, measurement conditions can be generalized and a long term evaluation can also be made. A given temperature variation is imparted to an object and the heat shock resistance is evaluated, based on the variation data of temperature with time for the entire object. When the shape or the material of a refractory product is modified, the effect of modification onto the heat shock resistance can be evaluated nondestructively.

摘要： PROBLEM TO BE SOLVED: To improved a gas sealing effect for preventing oxidation of molten steel and to extend the service life of a slide plate by arranging blowing holes at the peripheral edge parts mutually faced in the longitudinal direction of the plate base material and the opposite position to a molten steel pouring hole and the actual operating surface of the plate base material. SOLUTION: The slit state blowing holes 16a, 16b are arranged at the inner peripheral upper part 3u of the peripheral edge parts 15a, 15b mutually faced in the longitudinal direction of the plate base material 2, constituted with the inner peripheral upper part 3u of a frame body 3 and the outer peripheral upper part 11u of the plate base material 2, and this blowing holes 16a, 16b are communicated with a gas passage 12. Therefore, at the time of pouring the molten steel, the invasion of the air from the molten steel pouring hole 10 by passing through fine gap developed between the sliding surface of a fixed plate and the sliding surface 7 of the slide plate 1, is prevented with inert gas blown from the blowing holes 16a, 16b, and it is effectively prevented that the molten steel is oxidized and deteriorated by the invaded air. Further, the neiboring part 20 of the molten steel pouring hole 10 becoming high temp., is cooled with the inert gas.

摘要： PROBLEM TO BE SOLVED: To prevent the leakage of molten steel and to achieve the miniaturization of a refractory for sliding gate according to the miniaturization of the shape of an upper nozzle by arranging a projecting part for positioning, engaged with the lower outer wall or the refractory of a molten metal holding vessel, at the outer periphery at the lower end of the upper nozzle. SOLUTION: In the case of inserting the upper nozzle into a well block 1 in a molten metal holding vessel of a tundish or a ladle, etc., from the lower part, the projecting part 6 for positioning the upper nozzle 2 is engaged by hitting to the lower outer wall 7 or the refractory 11 or the recessed part 10 formed therein in the molten metal holding vessel and the upper nozzle 2 is not inserted into deeper position than the engaging position of the well block 1 and is held at the fixed position in the well block 1. In this way, the interval between the lower surface of the upper nozzle 2 and the upper plate 3 of the sliding gate can be held constant. Therefore, the interval between the lower surface of the upper nozzle 2 and the upper plate 3 of the sliding gate is not enlarged longer than required and small quantity of mortar is enough.
