Abstract
A method of forming a metal feedstock from wasted metal products is disclosed. The method includes the steps of crushing the metal products into pieces; magnetically separating sheet-shaped ferrous scraps and ferrous cast blocks from the crushed pieces; placing the cast blocks between the sheet-shaped scraps to make a sandwich structure; and pressing the sandwich structure to form a metal feedstock.
Claims17
A method of forming a metal feedstock from wasted metal products comprising the steps of
- crushing the metal products into pieces;
- magnetically separating the crushed pieces into sheet-shaped ferrous scraps and ferrous cast blocks;
- placing the ferrous cast blocks between the sheet-shaped ferrous scraps to make a sandwich structure;
- and
- pressing the sandwich structure to form a metal feedstock.
An apparatus for forming a metal feedstock from wasted metal products comprising
- a first, second and third measuring means for measuring out an amount of sheet-shaped scraps, cast blocks and sheet-shaped scraps, respectively, said scraps and blocks being obtained by crushing waste metal products;
- a transport means for successively transporting the sheet-shaped scraps, the cast blocks and the sheet-shaped scraps measured out by said first, second and third measuring means respectively;
- a holding means for receiving and holding the sheet-shaped scraps and the cast blocks transported by said transport means;
- and
- a pressing means for simultaneously pressing the sheet-shaped scraps, the cast blocks and the sheet-shaped scraps in said holding means to form a metal feedstock of a sandwich structured.
A metal feedstock comprising ferrous cast blocks and sheet-shaped ferrous scraps wherein said cast blocks are disposed between said sheet-shaped scraps and pressed together to form a sandwich-structured metal feedstock.
