Abstract

The utility model discloses a cooling device for high speed wire laying heads, aimed at solving the problems of finished product steel-heaping accidents and high consumption caused by irregular wire coiling and fast inner wall surface wearing of pipe of laying head when self-cooling techniques are used for high-speed and temperature wire rolling. An outer pipe is arranged inside the delivery pipe where the wire bars from the laying head pass through, which is communicated with the pipe of laying head. An inner pipe is arranged inside the outer pipe. An air passage is arranged between the inner pipe and the outer pipe, in which an inlet manifold is plugged. The cooling water in the inner pipe is dispensed into fine spray by the compressed air in the outer pipe, which is adhered on the inner wall of the pipe of laying head, thus quickening the cooling speed of the wire rods and protecting the inner wall of the pipe of laying head by reducing wear of the pipe of laying head and in turn improving the period of usage of the pipe of laying head and reducing finished product steel-heaping and laying head blocking accidents and downtime. Up to 830,000 RMB can be directly and indirectly saved on per production line of the steel plants.

Description

High-speed rod weave silk the part cooling device
Technical field
The utility model belongs to the rolling machinery auxiliary equipment, and is specifically a kind of to the weave silk device of part cooling of the wire rod after the hot rolling.
Background technology
In the production of high-speed rod, the rolling wire rod that comes out enters laying head behind conduit, spinneret, rotate lopping at a high speed in laying head, throws away into coiling of round from the wire vent hole then, is commonly called as to be wire rod.Finished product sortie mill speed is fast, temperature is high because wire rod goes out, and causes wire rod when passing spinneret, and is fast to the transducer wall ' s abrasion of spinneret, make and occur groove in the spinneret, thereby cause the circle of weaving silk disorderly, easily in Laying head, block, cause heap steel accident behind the finished product sortie.In order to eliminate above-mentioned phenomenon, must frequently change wearing and tearing and the spinneret of groove occurring, especially when producing the harder steel grade of steel, change very frequently, otherwise can influence lumber recovery, a production line will more be changed 120 of spinnerets every year, consumes height; Frequent simultaneously replacing spinneret effort is time-consuming, and what influence was produced normally carries out, and is seriously restricting the production of high-speed rod.
The utility model content
Technical problem to be solved in the utility model is, overcoming the existing wire rod lopping equipment of producing is by the nature cooling, because rolled wire speed is fast, temperature is high, to the tube wall quick abrasion of weaving silk, cause weaving silk circle disorderly, pile the steel accident and consume high shortcoming, the cooling device that provides a kind of high-speed rod to weave silk part after causing the finished product sortie.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the wire rod at Laying head exports in the conduit of process, the outer tube that leads in the spinneret is installed, in the tube chamber of outer tube, be with interior pipe, leave air flue between interior pipe and the outer tube, the air flue in air intake branch inserts between pipe and the outer tube.
The utility model also has following technical characterictic:
Air flue in described between pipe and the outer tube is an annular;
An end in spinneret of pipe and outer tube in described, the length of outer tube slightly is longer than interior pipe;
Described air intake branch is the air flue between pipe and outer tube in the oblique insertion of wire vent direction of wire rod.
Advantage of the present utility model and good effect are that because the interior pipe of sleeve pipe leads to cooling water, the logical compressed air of outer tube, entering of pressure-air atomizes cooling water, form high-pressure water mist, spray in the spinneret along conduit, high-pressure water mist has quickened the cooling velocity of wire rod attached to the inwall of spinneret; Simultaneously; high-pressure aerial fog forms one deck air film at the spinneret inwall, and the spinneret inwall is also played a very good protection, and has slowed down the wearing and tearing of high-speed rod to spinneret; improve the service life of spinneret, reduced heap steel and card Laying head accident behind the finished product sortie.
After using above-mentioned cooling device, production line is produced only needs 12 spinnerets every year, saves surplus the direct cost about 430,000 yuan; Can utilize the scheduled overhaul time regularly to change according to life cycle during replacing, the shutdown outside the plan in having avoided producing have improved production efficiency; Reduce the wearing and tearing of spinneret, improved the lumber recovery of wire rod; Reduce downtime and two of the rates of reducing the number of rejects and seconds, year can increase income about 40 surplus ten thousand yuan, like this, one can be that enterprise saves directly production line year and indirect expense reach 830,000 surplus yuan.Simultaneously, also prevented the generation of the accidents such as scald that cause because of the spinneret temperature is high.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the B portion enlarged drawing of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Among Fig. 1, spinneret cooling device 3 is to pass through the conduit 1 that is fixed on the base 2 at wire rod rolling on the Laying head 7, enters laying head 5, after coiling in laying head 5, discharges to conveyer belt through wire vent hole 6.In conduit 1, the outer tube 3.2 that leads in the spinneret 4 is installed, pipe 3.3 is provided with air flue 3.4 between interior pipe 3.3 and the outer tube 3.2 in the inner chamber of outer tube 3.2 is provided with, and even, smooth and easy for air inlet, described air flue 3.4 can be made as annular.Communicate in the annular air channel 3.4 between air intake branch 3.1 insertion outer tubes 3.2 and the outer tube 3.2 and with it; Resistance when reducing air intake branch 3.1 air inlets, air intake branch 3.1 is towards the oblique insertion of wire vent direction (referring to Fig. 2) of wire rod.In pipe 3.3 can be concordant with the end of outer tube 3.2 in spinneret 4, but pipe 3.3 in preferably outer tube 3.2 slightly is longer than feeds cooling waters in the interior like this pipe 3.3, feeds compressed air between interior pipe 3.3 and the outer tube 3.2, compressed air can lead cooling water to advance, and makes the atomizing of cooling water more abundant.
During use, air flue 3.4 in air intake branch 3.1 is introduced compressed air between pipe 3.3 and the outer tube 3.2, be enclosed in outside the tube wall of interior pipe 3.3, pipe 3.3 cooling waters of sending here were crashed to pieces and become granule in the pressure of air made, the cooling water atomizing forms high-pressure water mist, and spray in the spinneret 4 along conduit 1, high-pressure water mist is attached to the inwall of spinneret 4, and the tube wall of the spinneret 4 that has made by wire rod 7 roasting heat also can cool off fast and can not scald the people; Simultaneously, high-pressure aerial fog forms one deck air film at the inwall of spinneret 4, and spinneret 4 inwalls are played a very good protection, and has slowed down the wearing and tearing of 7 pairs of spinnerets 4 of high-speed rod, has prolonged the service life of spinneret 4.
