摘要： PURPOSE:To protect a lime filter against steam in the stage of preheating a vessel for a molten metal provided with said filter and to prevent deterioration of the structure owing to a hydration reaction in the stage of preheating the vessel by covering the filter with a shielding body. CONSTITUTION:A vessel 1 for a molten metal is lined internally with a lining material 6 and is coated with a coating material 7 on the surface thereof. A CaO-contg. filter 2 is installed therein in such a way that the base and both flanks of the filter contact tightly the material 7 via a partition plate 8. A refractory material 9 is imposed thereon and the top surface is fixed by a keep plate 5. A shielding body 10 is then pressed to both end faces of the filter 2 in the direction where a molten steel passes so as to cover the filter. The shielding body is wound and set by a metal wire, etc. A top cap 13 is then placed thereon and is heated by a gas burner 11 to perform simultaneously drying of the material 7 and preheating of the inside of the vessel 2. The gas consumption and preheating time required for preheating are reduced by half according to the above- mentioned method.

摘要： PURPOSE:To adsorb away a fine Al2O3 inclusion by installing cylindrical refractories of lime by paralleling the axial direction thereof in the flow direction of a molten steel, between the inflow port and outflow port for the molten steel in a tundish. CONSTITUTION:Cylinders 1 formed of lime refractories are stacked between a long nozzle 3 which charges a molten steel from a ladle into a tundish 2 and a charging nozzle 4 which charges the molten steel from the tundish 2 into a continuous casting mold. Said cylinders are held by a keep plate 5 and are thus prevented from floating. The refractories 1 are so disposed that the axial direction thereof parallels with the flowing direction of the molten steel in the tundish 2. Fine Al2O3 is thus absorbed by the refractories 1 and the refractories 1 are hardly eroded.

摘要： PURPOSE:To prevent the adhesion of a molten steel and a nozzle clogging and to prolong the service life of the nozzle by forming the thermal spraying layer of the material difficult to wet to the molten steel on the surface of a nozzle inner hole and discharging hole. CONSTITUTION:A thermal spraying layer 9-1 is formed on the surface of the inner hole inside by inserting a thermal spraying nozzle from an opening 12 in the state of removing the center part 11 at the bottom of a dipping nozzle. The thermal spraying layer 9-2 onto the surface of the discharging hole inside is performed by inserting the thermal spraying nozzle into the discharging hole and on the other hand the thermal spraying layer 9-2 onto the apex face to the center 11 at the bottom is performed in the state of removing the center part 11. Thereafter the bottom center part 11 is screwed in the opening hole 12 of the outer periphery 10 at the bottom. The nozzle clogging by the attachment with an alumina as the main component to the inner hole and discharging hole parts of the dipping nozzle for continuous casting is thus prevented and the service life of the nozzle is prolonged.
