Embodiment
Below in conjunction with embodiment, the utility model is further described.
Water cooling spraying and quenching device in Fig. 1 comprises: main body 101 and shower nozzle 102, main body 101 inside is provided with cooling chamber, main body 101 is symmetrically arranged with two liquid-inlet pipes 103 perpendicular to steel wire 3 traffic direction, shower nozzle 102 prolongs the cooling chamber that steel wire 3 traffic direction runs through main body 101, shower nozzle 102 is hollow cylindrical, be provided with the pore 104 that diameter is 1.0mm ~ 1.5mm, every square centimeter can arrange 6 ~ 9.
As depicted in figs. 1 and 2, pore 104 can be regularly distributed on hollow circuit cylinder, also as shown in Figure 3, often can arrange between pore and be mutually in staggered distribution on hollow circuit cylinder.
The vertical section of the pore in Fig. 1 can be rectangle, and also can be isosceles trapezoid, the conveniently process for processing of device, main body 101 and shower nozzle 102 be threaded connection, and conveniently can replace shower nozzle as required in use.
When the water cooling spraying and quenching device utilizing the utility model to provide cools, water cooling spraying and quenching device 1 is placed in quenching tank 2 and forms quench water circulation line 5 with well heater 4, quench water water tank 6, first high pressured water circuling pump 7, cooling tower 8 and the second high pressured water circuling pump 9 and tap water water tank 10 form cooling water pipeline 11, and quench water circulation line 5 and cooling water pipeline 11 are connected to form water cooling system as shown in Figure 4 by plate heat exchanger 12.Cooling water pipeline 11 is for carrying out cooling process by the quench water in plate heat exchanger 12 pairs of quench water pipelines 5, in quench water pipeline 5, well heater 4 is used for carrying out samming to quench water, the quench water temperature being delivered to water cooling spraying and quenching device 1 is made to maintain 40 DEG C ~ 60 DEG C, the steel wire 3 of heating to transmit with the speed of 50-60m/min under the drive of transmission mechanism (not shown) radially across shower nozzle 102, the high pressure water of 40 DEG C ~ 60 DEG C is inputted by liquid-inlet pipe 103, high pressure water under the effect of the pressure, atomized spray is formed on the steel wire 3 of heating by the pore 104 on shower nozzle 102, the homogeneous moisture film of one deck is formed in Steel Wire Surface, both make use of the feature that the heat conduction efficiency of water is high, utilizing again moisture film to form a kind of protective layer in Steel Wire Surface makes steel wire be unlikely to too fast cooling, avoid steel wire because cooling and embrittlement fast, steel wire is fully cooled, structural transformation is even.Along with the reduction of wire temperature, a large amount of moisture vaporization, cooling chamber is discharged along with the transmission of steel wire, some quench water enters in quench water water storage tank 10 along with pipeline, and temperature displacement is carried out by plate heat exchanger 12 and the tap water in cooling water pipeline 11 under the effect of the first high pressured water circuling pump 7, again by entering water cooling spraying and quenching device 1 after well heater 4 samming after replacing, liquid-inlet pipe 103 just can quench to steel wire by conveying high-pressure water endlessly.
