【考案の詳細な説明】
本考案は高炉出銑樋等の溶融金属容器に不定形
耐火材料を内張施工するための振動成形用中子に
関するものである。[Detailed Description of the Invention] The present invention relates to a vibration forming core for lining a molten metal container such as a blast furnace tap trough with a monolithic refractory material.
樋の内張施工には流し込み施工方法が広く採用
されているが、この方法では耐火材料に水分を添
加しているため施工体の乾燥に長時間を要すると
いう欠点がある。最近流し込み施工方法に代わる
ものとして乾式振動成形方法が開発されている。 The pouring method is widely used for gutter lining construction, but this method has the disadvantage that it takes a long time to dry the constructed material because water is added to the fireproof material. Recently, a dry vibration molding method has been developed as an alternative to the pouring method.
乾式振動成形方法は水分を添加していない耐火
材料に振動を与えて流動状態として充填を行い、
耐火材料中に含有された硬化剤の働きによつて施
工体を硬化させ成形するものである。そして樋内
に中子をセツトしたのち材料を投入し、振動機に
より中子を介して材料に振動を与えて充填し、施
工体が硬化した後、中子を脱枠するという工程で
施工されるものである。 In the dry vibration molding method, vibration is applied to the refractory material to which no moisture has been added, and the material is filled into a fluidized state.
The construction object is hardened and shaped by the action of a hardening agent contained in the fireproof material. After setting the core in the gutter, the material is put into the gutter, and a vibrator vibrates the material through the core to fill the material. After the construction body has hardened, the core is removed from the frame. It is something that

をセツトし、次の施工場所を施工する際の振動に
より充填完了の施工体が損傷されないようにして
いるが、これでは兼用型中子とダミー中子の入れ
替え作業に煩雑な手数を伴う。 In this type of vibration molding, the core conventionally used is a dual-purpose type that has the dual function of applying the vibrations of the vibrator to the material and maintaining the shape of the constructed object until the material hardens. The construction site cannot be moved to the next construction site until it has completely hardened and can be removed from the frame. This is extremely inconvenient during construction, so conventionally, when filling is completed, a dummy core is set in place of the dual-purpose core without waiting for complete hardening, and vibrations are generated when constructing the next construction site. This prevents damage to the completed construction body, but this involves a complicated task of replacing the dual-purpose core and the dummy core.

適宜の個所に備えた振動機である。 In the preferred embodiment of the present invention shown in the figure, the shape-retaining core 1 is gutter-like and has a double structure inside and outside, and at the upper ends of both longitudinal ends, beam members are attached. It is supported by a pillar 4 via 3. This core 1 does not necessarily have to have a double layered structure inside and outside, but may have a single layered structure. The vibration core 2, which is removably combined with the shape-retaining core 1, has an outer diameter corresponding to the inner diameter of the core 1 and a length slightly shorter than the core 1. Shape retaining core 1 from between 3 and 3
It has a structure that allows it to be inserted and removed inside. This vibrating core 2 may be supported by the shape-retaining core 1 as shown in the figure, or it may be supported by a support via a beam material as in the case of the shape-retaining core 1. configuration may be adopted. In the figure, 2a is a vibrator provided at appropriate locations on the bottom and both side surfaces of the vibrating core 2.

成形施工を完了するものである。 After removing residual iron (first step) and constructing the lining (second step) as usual, the core of the present invention is set in the molten metal container c (third step), and then the filling formed on the outside of the core is set in the molten metal container c (third step). Inject the monolithic refractory material a into the gap b (fourth step), then drive the vibrator 2a to densely fill the filling material while vibrating it through the core of the present invention. Among the cores of the present invention, the vibration core 2 is removed from the frame while leaving the shape-retaining core 1 (fifth step), and then, after the filling material a has hardened, the shape-retaining core 1 is removed from the frame. (Sixth step) This completes the vibration molding construction.

なく滓樋、溶銑鍋、溶鋼鍋などにも適用できる。 In this way, in the core of the present invention, the shape-retaining core 1 and the vibrating core 2 are removably combined, so after the vibration molding and filling is completed, the shape-retaining core 1 is left behind. The vibration core 2 can be immediately removed from the frame, and there is no need to replace it with a dummy core. Also, the vibrating core 2 unframed in this way
By combining with other shape-retaining cores 1, vibration molding can be carried out again, and if multiple shape-retaining cores 1 are set, such vibration molding can be carried out one by one from one construction site to another. It can be carried out continuously, and work efficiency can be significantly improved. For example, as shown in Fig. 3, a shape-retaining core 1 having an outer shape that matches the width of the gutter.
By preparing multiple units, continuous construction can be carried out by moving the vibrating core 2 in the length direction of the trough 5, even when the width of the trough is different, such as a blast furnace tap trough. can. The present invention can be applied not only to blast furnace tap troughs, but also to slag troughs, hot metal ladle, molten steel ladle, etc.
