SU48391A1 - Press with a carousel table for hot briquetting of metallurgical chips - Google Patents

Description

Generally known briquette presses with a rotating table, having through holes for the compressible substance, as well as the briquetting of metal chips with heating by means of an electric current passing through it, are not novel. However, the use of a giver that gives much better results compared to cold mechanical briquetting, both in terms of greater product strength and lower press power, the method of hot briquetting metal chips in practice is difficult due to the lack of an appropriate press device, the design of which would be quite simple and would give the opportunity to satisfactorily implement this method.

The present invention aims to resolve this issue by applying a press, the matrices of which, located in a rotating table, are separated from each other by electrically insulating gaskets. The HaipeB chips, which fill the cells of the dies, are made using arcuate coitactas located above and below the dies and connected to the poles of the current source.

In FIG. I and 2 depict the press scheme in two projections {with a partial section).

In the carousel table 1 of the press, matrixes 2 are installed along its periphery, with through cells 3. In that part of the table where electric heating is to be made chips, the cells are covered at the top and bottom by fixed tires 4, to which the current 5 is connected. By pressing, the loose chips are compressed, and the height of the filled material is given a different distance between the tires. The rotary table 1 thus moves the prepared chips along the tires, and the chips close the current, which produces its heating during the whole time while it moves between the tires. At the end of this period, the chips go under press 6, which is finally pressed in the hot state. The same press pushes the previously briquetted metal into the neighboring matrix with its second punches. Pre-pressing the loose chips can be done with a third punch of the same press or, in the case of two rows of dies, with a special press.
