Mechanization of the doffing of the green product from the presses and forming the charge on the kiln trucks

Conclusions

Six designs were chosen as standard types, viz., two charge-setting machines, three row-forming units, and a charge manipulator. The standard type machines are suitable for the mechanization of the loading of most types of product on the kiln trucks.

The charge-setting machines, which are designed to carry out all operations from the doffing of the green product from the press to its stacking on the kiln truck in a grid pattern, can be used to form a kiln charge of only a single type product in the form of standard bricks or ladle refractories, provided the charge-forming point is situated near the press.

Row-forming machines are intended for the doffing of the product from the press, arranging it in rows, and forming columns from the rows. If the charge-forming point lies near the press these machines can be used for placing the rows in columns directly on the kiln truck. If the charge-forming point is remote from the press the rows are built up to columns on a transfer device which conveys them to the charge-forming point.

Kiln-charge manipulators are designed for the operation of loading the charge columns on the kiln truck and can be used for the formation of a column-type charge of any desired height consisting of one or more than one type of product.

The technical documentation for the series production of the standard equipment for the mechanization of the loading of the product in the kiln trucks is being prepared by the All-Union Scientific-Research Institute for Mechanization in Ferrous Metallurgy on the basis of specimens which proved their worth either in long-term service or in experimental industrial-scale tests. The preparation of the technical documentation is being centralized in a single organization because of the necessity for a maximum standardization of the individual subassemblies as demonstrated by cumulative experience and requirements.
