(54) COOLING DEVICE

one

The invention relates to heat treatment, and more specifically to devices for rapid cooling.

A device for cooling articles, in particular slabs, etc., 1 which contains a bath, an endless conveyor moving along guide rollers, by means of which the workpieces are moved through the cooling bath 1, is known.

The closest to the proposed technical essence and the achieved result is an installation for cooling slabs, containing a bath, a loading-unloading mechanism and a mechanism for moving products, made in the form of a vertically closed conveyor with carriages 2.

Lack of known installations -. uneven cooling at the initial moment, warping of slabs and an increase in the size of the installation due to the presence of a reverse idle run of the carriages.

The purpose of the invention is to ensure uniform cooling, increase productivity and eliminate the intersection of the drive chain with moving parts when crossing them by performing a chain

with the possibility of its location on either side of the guides.

This goal is achieved by the fact that a device for cooling products, mainly slabs, containing a bath, a loading-unloading mechanism and a product transfer mechanism, made in the form of a vertically closed conveyor with carriages, are equipped with sectional guides installed along the conveyor for moving the carriages 10 while part of the sections are designed to move in a direction perpendicular to the longitudinal axis of the device in the horizontal plane, and is located in the zone of action of the loading-in mechanism Booting and in places of transition of the carriages with one guide to another.

In this case, the conveyor is equipped with intermediate stars located at the transition points of the carriages.

20 In FIG. 1 shows the device, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one.

The device contains a bath 1 in which the slab cools, a roller conveyor 2 for transferring hot and producing cold rolled products, a pusher 3 for pushing the slab all the way up against the loading fork 4, a drive 5 for turning the charging fork, carriages 6 moving on the rollers 7, two or several parallel lines 8 and 9 with fixed sectional guides 10 and a movable section 11 with hydro or electric drive 12 for moving carriages from the loading fork to the axis of the line, moving sections 13 and 14 with a drive 15 for moving carriages with slabs from one line to to a friend u, chain transmission 16 with drive 17, idler intermediate sprocket 18 and stops 19.

The device works as follows.

The hot slab on the roller table 2 enters the loading / unloading zone and is pushed by the pusher 3 until the loading fork 4 stops, the loading fork is rotated by means of the actuator 5 and installed on the carriage 6, placed with its lower part in the cooling tank 1. CLb begins to cool rapidly. The movable section 11 with the carriage 6 fixed on it is moved in a plane perpendicular to the longitudinal axis of the device in the horizontal direction until it is aligned with the stationary sectional guide. Next, turn on the chain gear 16, on the chain of which are located the pushers that engage with the stops

19, located on the carriages 6, the carriage moves by one step and is mounted on the movable section 13. At the same time, the carriage 6 with the cold slave enters the mobile section 11 and thereafter the movable section 11 with the carriage on which the slab moves in the direction of the loading fork 4, which takes the slab, turns and gives out a cold slab on the roller table 2, after which it is transported for further processing.

Simultaneously with the movement of the movable section 11, the moving sections 13 and 14, which move the carriages from line 8 to 9, begin to move, with the mobile section 13 moving the carriage with a slider, and

movable section 14. returns to line 9 without a carriage.

The chain transmission is equipped with blank intermediate sprockets 18, which allow the drive chain to be positioned with

either side of the movable sections and eliminates the intersection of the drive chain with the movable sections 11-14 as they move. The proposed device provides intensive slab cooling, uniform in thickness, significantly reduces the formation of secondary scale, facilitates operating conditions and increases productivity.

Claims (2)

1. A device for cooling products, mainly slabs, containing a bath, loading-unloading mechanism and mechanism transporting articles, made in the form of a vertically closed container with carriages, characterized in that, in order to ensure uniform cooling and increase the productivity of the device, it is equipped with sectional guides installed along the conveyor in a direction perpendicular to the longitudinal axis of the device in the horizontal plane , and is located in the zone of action of the loading-unloading mechanism and in the places where the carriages transition from one guide to another. 2. The device according to claim 1, characterized in that, in order to eliminate the intersection of the drive chain with the moving parts as they move by making the chain with the possibility of its location on either side of the guides, the conveyor is provided with intermediate sprockets located at the transition points of the carriages.
