Description

The invention relates to the rolling of metal, in particular, to devices for cooling rolled products in a stream of wire or section mill.

A known section of the longitudinal rolled products line includes cooling wiring made in the form of a cylindrical chamber, a system for supplying and discharging coolant with a drip cover and a drain system.

However, this section does not have devices for cleaning the used liquid from T solid particles.

A wiring path section is also known, comprising a line of cooling wiring housed on the base of the fluid inlet and outlet system. The base is made in the form of a receiving tray, where liquid with scale is drained from the cooling wiring. A mesh is installed at the bottom of the tray to trap particles of wood (scale, pieces of wire). The liquid from the tray goes into the sewer.

When using this section, the grid of the tray t becomes obstructed with human particles. The liquid overflows the tray and spreads on the floor, which deteriorates the working conditions, lowers the production culture, and reduces the reliability of the section.

Closest to the invention is a wiring route section with a system for descaling wire with a liquid, including a wiring line, a supply and removal system. The liquid along with the scale enters the collection trays, from which the piping system is discharged into a separate tank with a filter for descaling. The tank is connected to an overflow pipe with a reservoir for purified water.

However, installing cleaning devices at a certain distance from the wiring route using a piping system leads to clogging of pipelines, which reduces the reliability of the section.

The purpose of the invention is to reduce the dimensions of the section and reduce the downtime of the mill by increasing the efficiency of water purification after cooling.

The goal is achieved by those. that in the section of the wiring route containing the wiring with the nozzles of the water supply and the water drainage system, the liquid drainage system is made of containers placed one into another with the formation between them of a cavity for overflowing water from the inner tank to the outer tank, and the cooling wires are fixed above the inner tank.

1 shows a conductor path section, a longitudinal section; figure 2 - section aa; figure 1: fig.Z - section BB in figure 1.

The section contains cooling wiring 1 with water inlet nozzles and a system 2 for draining water. The system 2 of water (liquid) removal is made in the form of containers 3.4 placed one inside the other with the formation of cavities 5 for the overflow of water for the overflow of water from the internal container 3 to the external 4. Cooling lines 1 are fixed above the internal container 3. The cavity 5 serves for draining purified from m particles b,

5 for example scale, pieces of wire, liquid. In places where the liquid exits the cooling wiring 1 at the length I of the inner wall 3 and the outer 4 containers are tightly interconnected by a strap 7

0 to prevent the suspended particles from entering the cavity 5 immediately after leaving the cooling wiring 1. The containers 3.4 are made with separate outlets 8, 9. 8 the bottom of the internal container 3 in

5 a drainage hole 10 is installed a stopper 11 with a protective grid 12. A channel 8 for draining the cleaned liquid by means of a pump 13 is connected to a system 14 for supplying cooling liquid, thus forming a closed cycle. .

The section works as follows. During the heat treatment of the metal using cooling wires)) ok 1, the liquid from the supply system 14 is fed to

5 cooling wiring 1. Then the waste liquid along with the dross 6 enters the inner tank 3. The dross 6 settles at the bottom of the inner tank 3, the drainage hole 10 is closed by the stopper 11, and the purified water overflows through the walls of the inner tank 3 (in the middle parts of the section where there is no interposer 7, fig.Z) falls into cavity 5. Cleared; on water through channel 8 using pump 13

5 is supplied to the fluid supply system 14 to form a closed loop, or, if necessary, to sewage.

Periodically, the bottom of the inner container 3 is cleaned from scale 6. To do this, remove the plug 11 from the drainage

0 openings 10 and, drain the sedimented liquid from the inner container 3 by opening the valve 15 of the drainage opening 10. Then remove the scale 6, close the valve 15 and replace the plug 11. The section is ready for operation again,

Performing a drainage system in the form of two containers placed one inside the other With the formation of a space between them for overflowing water from into the (| morning to the outside capacity), it allows the descaling of the liquid directly in place and using the purified liquid for re-cooling, while solid particles remain in the inner tank and the MOs clog the drainage channels, which prevents the liquid from overflowing over the edge of the receiving tray to the floor of the workshop and, thereby, enhances the production culture, increases the reliability of the wiring section races, reduces mill downtime, increases productivity. The wiring section is compact, cooling wires are fixed above

internal capacity, which reduces the size of the section.
