Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the thermal treatment cooling and shaping water-jet that is used for various steel such as helix rib steel wire, rod iron of the present utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein is only in order to explanation the utility model rather than to restriction of the present utility model.
Shown in Fig. 1～4, steel heat of the present utility model is handled the cooling and shaping water-jet, comprise overcoat 1 with water-in 2, water spray core 3, described overcoat 1 and water spray core 3 surround a water storage cavity 4, water coolant enters into described water storage cavity 4 from water-in 2, is ejected into by the spout hole 6 on water spray core 3 walls on the various steel 5 such as the helix rib steel wire of heat-treating cooling and shaping that passes described water spray core 3, rod iron.
Shown in Fig. 2～3, thermal treatment cooling and shaping water-jet of the present utility model, the spout hole 6 on the described water spray core 3 is arranged along branches such as water spray core 3 walls, and each row along the circumferential direction six five equilibriums has six holes.
The water coolant spray angle of described spout hole 6 is for being 84 degree angles with the parallel various steel 5 such as helix rib steel wire, rod iron that enter the water spray core.
Described water spray core 3 comprises import 7 and afterbody 8, and its import is 7 big, afterbody 8 is little.The import 7 of described water spray core 3 is that a cross section is the trapezoid hollow circular tube, afterbody 8 is that a cross section is rectangular hollow circular tube, the cross section trapezoid base diameter of described import 7 is greater than the diameter of described afterbody 8, the cross section trapezoid top diameter of described import 7 equals the diameter of described afterbody 8, and described import 7 and afterbody 8 are connected to form the hollow tube core that various steel 5 such as one section helix rib steel wire of heat-treating cooling and shaping, rod iron can pass through.
Preferably, as a kind of embodiment, as shown in Figure 4, described water-in 2 is two up and down, and its nominal diameter (Nominal Diameter) is DN25;
Described water storage cavity 4 is DN65, long 290 millimeters water storage cavity.
The trapezoidal cross-section base diameter that described water spray core 3 is an import 7 is 44 millimeters of Φ, and cross section trapezoid top diameter (equaling tail diameter) is 22 millimeters of Φ, and is connected with the special pipe that diameter is the afterbody 8 of 22 millimeters of Φ.
With an example steel heat processing cooling and shaping water-jet of the present utility model is described below, establishing cooling water pipeline water supply flow velocity is 1 meter per second, pressure of supply water 0.1MPa, 20 ℃ of temperature.
