摘要:
The present invention discloses a metal separator for a fuel cell including a reaction gas channel formed to protrude from a first face of the metal separator to a second face thereof, a coolant channel formed between the reaction gas channels protruding from the second face of the metal separator, a reaction gas manifold opened to introduce a reaction gas into the metal separator, a coolant manifold opened to introduce a coolant into the metal separator, and a stepped portion positioned at any one of the space between the reaction gas channel and the reaction gas manifold, and the reaction gas channel. This configuration serves to widen the reaction gas flowing portion and the coolant flowing portion on the metal separator, and prevent deformation of the reaction gas flowing portion and the coolant flowing portion, thereby improving efficiency of the fuel cell.

An apparatus for recovering valuable metals and manufacturing multifunctional aggregate from slag. The apparatus includes a slag reforming processing pot 10 in which molten slag discharged from a converter or an electric furnace is stored, a reducing agent introducing part 20 which introduces a reducing agent into the slag reforming processing pot from above, the reducing agent recovering valuable metals from the molten slag, a reducing agent inflow part 25 which inputs a reducing agent into the slag reforming processing pot through a lower portion of a side of the slag reforming processing pot, the reducing agent recovering valuable metals from the molten slag, and cooling units 30 and 40 which create bubbles and perform controlled cooling in order to convert the molten slag, from which the valuable metals are recovered, into a light material having a porous structure.
摘要:
The present invention relates to an apparatus for turning steel products. The apparatus includes a rotating shaft which rotates with external power applied thereto; a first turning plate which is fixed to the rotating shaft and oriented in a lateral direction of the rotating shaft, and which rotates along with the rotating shaft; and a second turning plate which is provided on the rotating shaft and oriented in a lateral direction of the rotary shaft. The second turning plate is moved forwards and backwards in the longitudinal direction of the rotary shaft and is removably coupled to the first turning plate.

The present invention relates to a scrap compactor and to an apparatus for manufacturing same. The apparatus for manufacturing scrap compactors includes a core by means of which a through-hole can be formed in a scrap compactor (S), improves the melting behavior of the scrap compactor by means of the through-hole (h), and also has the effect of preventing the deliberate misrepresentation of the weight of the contents of the scrap compactor carried out by inserting heavy substances into the scrap compactor instead of scrap.
