示されている。2. Description of the Related Art In the case of reusing scrap materials, press scraps, etc. of galvanized steel sheets for automobiles as steelmaking materials, zinc oxide, etc. shortens the melting furnace life. Therefore, the plated zinc must be removed from the steel. I have to. As a method for removing zinc from steel, a steel sheet for automobiles is not an example, but Japanese Patent Publication No. 61-23858 discloses that in a heating furnace,
The object to be treated is heated under reduced pressure to evaporate the zinc on the surface,
A method of depositing and collecting evaporated zinc on a collector is disclosed.

えられる。However, even if the above-mentioned conventional method is applied to remove zinc from scrap material of galvanized steel sheet for automobiles, highly efficient removal of zinc cannot be obtained. This is because the scrap material from the car shredder adheres mechanical oil and press oil and also contains impurities such as resin. When zinc is recovered and heated, these organic materials evaporate and react with zinc, resulting in ZnCl 2 , Z
It is considered that this is because a layer of a compound that hardly evaporates, such as nS or ZnSO 4 , is formed on the surface, and this hinders the evaporation of zinc (Zn).

Japanese Patent Application No. 3-146636 proposes a method capable of removing the adhered metal from the metal adhered steel sheet with high efficiency.
In this method, the material to be treated is heated at the zinc evaporation temperature or lower to evaporate the organic material, so that the organic material is prevented from reacting with zinc to form a compound when the zinc is recovered by heating. For this reason, zinc is smoothly evaporated during heat recovery of zinc,
It becomes possible to remove zinc with high efficiency.

In order to do so, it is necessary to divide the recovery device according to the processing temperature, which causes a problem that the equipment scale becomes large. In addition, it is difficult to sort metals and the like that evaporate at close temperatures by type, and it is difficult to efficiently capture both.
