Abstract

The utility model discloses a spray cooling device for the finishing area of a medium plate. A wheel disc type No.1 cooling bed and a wheel disc type No.2 cooling bed are arranged on the finishing area in the direction of the steel plate; a lower atomizing nozzle is arranged in the No.2 cooling bed area below the steel plate to be cooled and an upper atomizing nozzle is arranged in the No.2 cooling bed area above the steel plate to be cooled; the water spray port of the lower atomizing nozzle faces the lower surface of the steel plate to be cooled and that of the upper atomizing nozzle faces the upper surface of the steel plate to be cooled; and both the lower atomizing nozzle and the upper atomizing nozzle are communicated with a high-pressure water pipeline. The utility model adopts the structure that an abrasion-resistant plate is arranged on the upper surface of the lower shearing table, and the steel plate rubs the abrasion-resistant plate instead of directly rubbing the lower shearing table when passing, so that only the abrasion-resistant plate needs to be repaired in case of abrasion, and the thermal deformation of the lower shearing table is avoided, thereby guaranteeing installation precision and normal operation of a shearing machine, and further ensuring the normal production. Meanwhile, the structure is good for shortening required time for repair, improving work efficiency, and saving labor cost and material cost.

Description

Cut deal Runout area spray cooling device

Technical field

The utility model relates to a kind of cut deal processing auxiliary equipment, particularly a kind of cut deal Runout area spray cooling device.

Background technology

In the Plate Production Process, by rolling, cool off, cut limit and course of conveying, cutting the limit is that cut deal is cut into qualified size and dimension, to adapt to different market demands.

Along with the increase of the market demand, the updating of Heavy Plate Production technology, existing Heavy Plate Production equipment has rhythm of production faster; And follow-up cut the limit before process for cooling can not satisfy the requirement that fast pace is produced, particularly for the slab of thickness greater than 25 millimeters, plate speeds up by the cooling zone, can't fully cool off, temperature when cutting the limit generally will be higher than 300 ℃, blue limit can appear in this moment, influences the welding performance of slab; Influence the type quality and the shearing quality of slab simultaneously.

Therefore, need the cooling system of existing cut deal Runout area be improved, the steel plate cooling velocity is accelerated, slab temperature when shearing is reduced to below 300 ℃, simultaneously, can guarantee internal performance, type quality and the shearing quality of steel plate.

The utility model content

In view of this, the utility model provides a kind of cut deal Runout area spray cooling device, in use, the steel plate cooling velocity is accelerated, slab temperature when shearing is reduced to below 300 ℃, simultaneously, can guarantee internal performance, type quality and the shearing quality of steel plate.

Cut deal Runout area spray cooling device of the present utility model, be followed successively by Wheel-type 1# cold bed and Wheel-type 2# cold bed at Runout area by the steel plate trend, 2# cold bed zone is positioned at needs the bottom of cooling metal sheets that atomizer is set down, being positioned at needs the top of cooling metal sheets that atomizer is set, the water jet of described atomizer down is over against the lower surface of need cooling metal sheets, and the water jet of last atomizer is over against the upper surface of need cooling metal sheets; Described atomizer down and last atomizer all are communicated with the water under high pressure pipeline.

Further, described atomizer down is communicated in the water under high pressure pipeline by control valve I, and last atomizer is communicated in the water under high pressure pipeline by control valve II;

Further, the injection flow rate of described down atomizer be last atomizer injection flow rate 1.5-2 doubly;

Further, the spray angle of described atomizer down and last atomizer is 120 °;

Further, described down atomizer and last atomizer all in the mode of spacing 3-4 rice along horizontal uniform the setting in a row of need cooling metal sheets;

Further, described atomizer down and last atomizer are all along needing cooling metal sheets laterally to be reduced gradually by centre to both sides injection flow rate.

The beneficial effects of the utility model: cut deal Runout area spray cooling device of the present utility model, in the 2# of Runout area cold bed zone spray cooling device is set, steel plate is assisted cooling from two surfaces up and down, the steel plate cooling velocity is accelerated, slab temperature when shearing is reduced to below 300 ℃, be applicable to thickness greater than the cooling of 25 millimeters slab, be applicable to also that certainly thickness uses under given conditions less than 25 millimeters steel plate; Because the utility model is to be vaporific sprinkling cooling, local cooling can not occur to steel plate; And, owing to be located at the 2# cold bed, had bigger reduction than the steel billet temperature of firm bottom roll, can not cause the steel billet temperature rapid drawdown, thereby, can guarantee internal performance, type quality and the shearing quality of steel plate.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

Accompanying drawing is a structural representation of the present utility model, as shown in the figure: the cut deal Runout area spray cooling device of present embodiment, be followed successively by Wheel-type 1# cold bed (not marking among the figure) and Wheel-type 2# cold bed 1 at Runout area by the steel plate trend, 2# cold bed 1 zone is positioned at needs the bottom of cooling metal sheets 2 that atomizer 4 is set down, being positioned at needs the top of cooling metal sheets 2 that atomizer 3 is set, the water jet of described atomizer 4 down is over against the lower surface of need cooling metal sheets 2, and the water jet of last atomizer 3 is over against the upper surface of need cooling metal sheets 2; Described atomizer 4 down and last atomizer 2 all are communicated with water under high pressure pipeline 5.

In the present embodiment, described atomizer 4 down is communicated in water under high pressure pipeline 5 by control valve I 4a, and last atomizer 3 is communicated in water under high pressure pipeline 5 by control valve II 3a; Can regulate the injection flow rate of atomizer 3 and following atomizer 4 according to cooling off needs, the control cooling effect.
