Abstract: A method for recycling steelmaking dusts has a granulating step of mixing steelmaking dusts, containing as a principal component iron and oxides thereof produced during the steelmaking in a melting furnace, with a powder containing carbon as a principal component and granulating the resultant mixture to provide mixed granules, a water impregnating step of immersing the mixed granules in a water to allow them to be impregnated with the water, a solidifying step of molding the water impregnated, mixed granules under pressure within a mold assembly to provide a solid body of the steelmaking dusts, a step of transporting the solid body of the steelmaking dusts as a raw material to be charged into the melting furnace, an enhancing step of increasing the concentration of zinc in the dusts, and a dezincing step of dezincing the dusts during a period from acquisition of the steelmaking dusts out of the melting furnace to the solidifying step.

Abstract: Steelmaking dusts produced during the manufacture of iron and steel by means of a melting furnace and containing iron and iron oxides as a principal component are mixed, and granulated, with a powder containing carbon as a principal component to provide mixed granules. The mixed granules are, after having impregnated with water before the molding thereof, molded under pressure within a mold assembly to provide briquettes, which are solidified bodies of the steelmaking dusts. The briquettes are reused as a raw material to be charged into the melting furnace. When the dusts having a concentration of zinc enhanced are dezinced, reduction in amount of dezincing treatment and increase of the efficiency of the dezincing treatment can be achieved.

Abstract: A cylindrical ornamental body can protect a reflective member from being damaged and reducing production cost. The cylindrical ornamental body comprises a transparent cylindrical main body made of synthetic resin and a reflective member having a reflective face inserted into said cylindrical main body. An air layer is provided between the reflective face of the reflective member and an inner wall of the cylindrical main body. The reflective member is composed of a belt-like member having the reflective face on at least one face thereof and has a fixing portion which is fixed to the inner wall of the cylindrical main body at least along a side edge in the length direction thereof. A attaching portion may be provided integrally on part of an outer side face of the cylindrical main body along a longitudinal direction of the cylindrical main body.
