Background technology
Spiral is widely used in cement prefab, cassette ceiling structural member, concrete duct of the bar-mat reinforcement in airport, highway, tunnel etc. and protection network and civil buildings etc.Under identical service condition, improve the yield strength of spiral, can reduce the diameter of reinforcing bar, save steel to reduce cost; Under identical mechanical property condition, can promote the selling price that product uses class and final raising product by improving the rebar surface quality.
For improving the intensity of building bar, the technical measures that adopt mainly are carbon content and employing alloying and the micro-alloying technologies by improving steel at present, and its essence is to reach the purpose that improves reinforced steel bar strength by means of solution strengthening, precipitation strength and structure refinement etc.But thereby this technology is because of having increased Si, Mn content and/or having added the cost that microalloy elements such as Nb, V, Ti have improved reinforcing bar.
China Patent No. 00109495.5 discloses " production method of low-carbon screw thread reinforcing bar ", and its technical characterictic is that steel is at Ae
3And Ar
3Temperature range surpasses the finally rolling of 50% deformation quantity, carries out the water cooling of wearing that cooling rate surpasses 20 ℃/S after rolling, and it is cold to be cooled to 300～600 ℃ of laggard line spaces.Adopt this technology can improve the yield strength of reinforcing bar.It is high that but this patent of invention requires equipment, and general producer equipment is difficult to satisfy its production requirement.
Summary of the invention
Usually adopt the online water cooling of wearing in view of existing spiral cooling, be i.e. directly pass the tank of filling water after the reinforcing bar finish to gauge and cool off, require cooling water inflow big, pairing circulation power increases, in addition, this kind technology cooling velocity is less, and cold rear surface residual water can't be removed.The utility model purpose is to provide a kind of line cooling device of spiral, and is with low cost, simple to operate, cooling capacity is big, can improve the line cooling device of rebar surface quality simultaneously.
For achieving the above object, the technical solution of the utility model is, the line cooling device of spiral comprises, outer casing seat, in a cavity and an opening are arranged, also be provided with the intake channel that is connected with cavity on it; Inner casing base is inserted in the outer casing seat cavity, is provided with passage in the middle of it, and is corresponding with the outer casing seat opening; Outer casing seat, inner casing base assembling form cavity, and a gap is formed on the top of cavity, and the gap forms 360 ° of hoop line nozzles thus; Lead and let out block set, its two ends cooperate with outer casing seat, are provided with passage in the middle of it, and are corresponding with the outer casing seat opening.
Further, described leading let out the block set outer face and matched with the outer casing seat end face and form one and lead and let out groove.
The utility model also is provided with a base plate, described outer casing seat, leads and lets out block set and be fixed on this base plate.
Described line cooling device can arranged in series many.
The utility model steel billet adopts low temperature to come out of the stove and after rolling, reinforcing bar is by online every group of multiple tracks beam current type water cooling plant and beam current type gas equipment for drying, the even reinforcing bar circumferential surface of jetting at a high speed of the gentle transmitted beam under high pressure of water head piece hoop, realize that thereby the online surperficial cold treatment of wire rod improves the intensity and the surface quality of product, solve the problem of the on the low side and surface quality difference of intensity level that wire rod slowly causes because of air cooling.
The beneficial effects of the utility model
The utility model device can fast, evenly cool off reinforcing bar whole circumference surface by gentle the doing of multiple tracks hoop beam current type water-cooled under Gao Shui (gas) pressure, gas equipment for drying subsequently can rebar surface is residual the water mark evenly dry up and the remained on surface iron scale blown off, thereby improve surface quality of products and improve its intensity.
