Description
Technical field
The utility model belongs to wire rod rolling equipment, particularly relates 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 reverse cooling jet and air purge spray 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 tubes connection groove, straight hole, extend out conical water outlet, straight hole respectively with tubes connection groove, extend out conical water outlet and be coaxially connected.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, easily cause milling train to pile steel fault, equipment operation ratio is low, frequently changes nozzle, and spare parts consumption is large, greatly increases production cost.
Utility model content
In order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of high-speed rod rolling line water tank reverse cooling combined nozzle, and nozzle wear is little, reduce and change the frequency and production cost, reduce heap steel fault, stablize rolled piece quality, improve equipment operation ratio.
The reverse 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 three lobe guiding gutter successively on body, retaining keyway, retaining thread, rotate keyway, tubes connection groove and straight hole coaxial line is inside established to be connected, be characterized in establishing ring-shaped step in described tubes connection groove end, the tungsten carbide nozzle inner sleeve of its apertures is established in straight hole, nozzle inner sleeve rear end is resisted against on straight hole step, body is stretched out in front end, body, the central axis of nozzle inner sleeve on the same line, extend the life-span in gap between recoil nozzle entrance and recoil nozzle.During use, nozzle is fixed on nozzle holder, and coordinates with recoil nozzle casing, and cooling water is contrary with the direction of workpiece motion s, oppositely cools.
The utility model improves further, and described nozzle inner sleeve is connected and composed by more piece sleeve pipe and casing head, and sleeve structure shape is identical, and sleeve outer is consistent with the diameter of ring-shaped step end face, and casing inner diameter is consistent with straight hole aperture; Casing head external diameter is slightly larger than the diameter of ring-shaped step end face, and casing head adopts heat expansion method to be embedded in body straight hole, establishes tubaeform delivery port and be connected straight hole in casing head, connects straight hole and is coaxially connected with delivery port.
The utility model improves further, and described casing head is suitable with casing length, and casing head is 1:5 to 1:6 with the ratio of sleeve pipe overall length.
Compared with prior art, advantage is novel, and structure letter is gathered, rationally; The utility model adopts combining nozzle, tungsten carbide nozzle inner sleeve contacts with high temperature rolled piece, steel transportation amount reaches 8.2 ten thousand ton hours, and uneven wear is only 0.65mm, and wear extent is very little, can continue to use, long service life, improves rolled piece temperature control precision, the tissue of improving product, performance, stablize rolled piece quality, avoid occurring heap steel fault; Nozzle exchange number of times reduces simultaneously, and spare parts consumption reduces, and production cost reduces.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation of the reverse cooling combined nozzle of high-speed rod rolling line water tank;
Fig. 2 is side view of the present utility model;
