The cooling compound nozzle of the high-speed wire rod rolling water tank, disclosed by the invention, has the advantages that by means of the compound nozzle, the inner nozzle sleeve made of tungsten carbide is contacted with a high-temperature rolled piece; when the total steel amount is up to 82000 tons, the uneven wear is only 0.65 mm; the abrasion loss is very low, so that the nozzle can be used continuously; the temperature control precision of rolled pieces is increased; structures and properties of products are improved; the quality of the rolled pieces is stabilized; pile-up faults are avoided; simultaneously, the replacement time of the nozzle is reduced; the production cost is reduced.
Description
Technical field
The invention belongs to wire rod rolling equipment, particularly relate to a kind of high-speed rod rolling line water cooling box nozzle.
Background technology
High-speed wire rolling production line arranges water cooling box, in water cooling box, establishes cooling jet and cleaning nozzle to carry out cooling processing to rolled piece.In the operation of rolling, rolled piece is by the nozzle in water cooling box, by cut-out governing water yield size, to control rolled piece temperature, makes wire rod obtain tissue, the performance of expection.Current, the nozzle used makes hollow tube by steel alloy 3Cr13 monoblock cast, processing and heat treatment, body front end peripheral hardware is containing taper surface, nozzle rear end peripheral hardware retaining thread, inside establish containing taper water inlet and straight barrel type delivery port, taper water inlet is coaxially connected with straight barrel type delivery port, and the tapering of taper water inlet is consistent with the tapering of taper surface.Problems existing is in high temperature rolling process, nozzle contacts with the high temperature rolled piece of high-speed cruising, spray nozzle front end contact site wear extent is very large, when steel transportation amount is at about 1.2 ten thousand tons, wear extent can reach 2-3mm, and nozzle useless cannot regulating pondage size, and rolled piece temperature is out of hand, the cooling effect of rolled piece is poor, causes rolled piece qualification rate low; And excessive wearing and tearing can affect the direct motion of rolled piece, milling train is easily caused to pile steel fault; Equipment operation ratio is low, frequently changes nozzle, and spare parts consumption is large, greatly increases production cost.
Summary of the invention
In order to overcome the defect of prior art, the object of the present invention is to provide the cooling combined nozzle of a kind of high-speed rod rolling line water tank, nozzle wear is little, reduces and changes the frequency and production cost, reduces heap steel fault, stablizes rolled piece quality, improve equipment operation ratio.
The cooling combined nozzle of high-speed rod rolling line water tank, comprise the nozzle body be made up of steel alloy 3Cr13 entirety, body front end peripheral hardware is containing taper surface, peripheral hardware positioning spline, retaining thread, rotation keyway successively on it, be characterized in described nozzle body centrally axis establish two-stage stepped hole, establish the nozzle inner sleeve be made up of tungsten carbide in stepped hole, nozzle inner sleeve rear end face and body flush, body is stretched out in front end, and the central axis of body, nozzle inner sleeve on the same line.During use, nozzle is fixed on nozzle holder, and coordinates with jet expansion cover, and cooling water direction is consistent with workpiece motion s direction forward to be cooled.
The present invention improves further, in the middle part of described nozzle inner sleeve, peripheral hardware step matches with the stepped hole inside body, inner sleeve front end peripheral hardware taper surface and flushing with body taper surface is connected, and the external diameter of nozzle inner sleeve is slightly larger than the internal diameter of stepped hole, and nozzle inner sleeve and body are interference fit; Nozzle inner sleeve centrally axis establishes containing taper water inlet and straight barrel type delivery port, and taper water inlet is coaxially connected with straight barrel type delivery port, and the tapering of taper water inlet is consistent with the tapering of taper surface, water inlet and delivery port length ratio 1:(1-1.2).
Compared with prior art, advantage is novel, and structure letter is gathered, rationally; The present invention adopts combining nozzle, tungsten carbide nozzle inner sleeve contacts with high temperature rolled piece, steel transportation amount reaches 8.2 ten thousand ton hours, uneven wear is only 0.65mm, and wear extent is very little, can continue to use, improve rolled piece temperature control precision, the tissue of improving product, performance, stablize rolled piece quality, avoids occurring heap steel fault; Nozzle exchange number of times reduces simultaneously, and spare parts consumption reduces, and production cost reduces.
