The present invention relates to metallurgy, in particular to gate directions for cooling, hardening and hydraulic conveyance of rolling stock, e.g. bars.

It is a device "" for that purpose known which a number of tubular arranged one behind the other Contains chambers, each of which is at the entrance end

Has/'
an inflow nozzle, which guides liquid into this chamber for conveying and cooling the rolled cast iron, and "has an opening at the outlet end for discharging this liquid (the used coolant). Behind each chamber is the used coolant" 37. from the

Each of these devices consists of one at the chamber outlet end fortified Eohr, which is connected to the water supply source is connected (see the application filed in the EBD ITr. P.19O ^ 30 $ .9jund the "! filed in the GDR Registration number 40/134266).

However, this increases the water consumption and also the power is consumed to generate a high pressure jet that separates the used coolant and the steam jacket is used by the rolling stock at the exit from each chamber. This additional water consumption is 50 ... 70%. of total water consumption. In addition, additional equipment is used

The invention is based on the object of a Device for cooling, hardening and hydraulic conveying

of rolling stock with a device for separating the

used coolant to create which more economical is because it reduces water consumption;

Row of tubular, coaxially arranged chambers, of

each has an inflow nozzle at the inlet end, which flows into this chamber for conveying and cooling of the rolling stock and a device at the outlet end device which directs a jet of liquid,

A flap 9 is used to cone the amount of liquid supplied to the nozzle 7 and the superfluous used to drain away A nozzle 10 is provided for liquid.

The rolled stock, such as bars leaving the rolling mill in the hot state at 15 m / s speed and at 105 ⁰ C! Temperature are cured in the apparatus described, and cooled. The rods are transported by a stream of water and pass through a series of tubular, coaxially arranged chambers 1 and 2 »

It is used for conveying, hardening and cooling the rolling stock ^ into each chamber 1 and 2 of the device via the inlet nozzle 5 At the entry end, water at 40 m / s speed at a small angle to the rolling stock axis directed.

The bulk of the spent water flows through the opening 6 in the side wall of the pipe socket 5, and passes into the outlet connection 10. A portion of the spent Water is supplied to the nozzle 7. The ratio of the size of the flow of spent cooling liquid which is fed to the nozzle 7 to the size of the flow of this

'Liquid that gets into the drain port 10 is regulated by the position of the flaps 9.
