Abstract
The invention relates to an adjustable ring-shaped spiral-flow type cooling method. Water enters a ring-shaped cavity between a water cooler seat and a water cooler core, ejected water curtains surround the periphery of a steel material to be cooled to cool the steel material, the size of a water ring seam can be adjusted by adjusting the position of the water cooler core towards left or right, and after the position of the water cooler core is adjusted, the water cooler core is screwed and fixed by a lock nut; the water is ejected from a ring seam between the water cooler seat and the water cooler core to form a first path ring-shaped water curtain; the water is ejected from a small hole positioned on the front end of the water cooler core to form a second path rotation-shaped water curtain; when the front end of a water-cooled tube is not provided with a horn lip, a moving direction of the cooled steel material is in keeping with a water flow direction; and when the front end of the water-cooled tube is provided with the horn lip, the moving direction of the cooled steel material is reverse to the water flow direction. The invention can solve the problem that the size of the ring seam of a water cooler can not be adjusted.
Description
Technical field
The invention belongs to the cooling field, particularly relate to a kind of adjustable ring-shaped spiral-flow type cooling method.
Background technology
The controlled rolling of steel is a kind of raising steel serviceability with the control cooling, produces effective technique of III-IV level spiral.In this technical process, need high-effect cooling device, the cooling velocity of steel is controlled.Make a general survey of cooler both domestic and external, nothing more than three kinds of direct injections, turbulence type, spiral-flow type, wherein the cooler of direct injection is comprised of nozzle core, water cooler seat and water cooling tube.Cooling water is enclosed in around the spiral of heat by the circumferential weld ejection of water cooler, carries out heat exchange.This water cooler is often made open type (being combined by two halves, such as the root milling train that rubs of the U.S.).Thereby hydraulic pressure is lower, and the water-cooled effect is bad, is only applicable to the less rod of diameter, wire rod cooling.Turbulent flow cooler is comprised of nozzle core, turbulent flow body and water cooling tube, and water is by spraying in the circumferential weld, and is enclosed in around the steel by the turbulent flow body, and carries out turbulent flow.Because Reynolds number increases, thereby heat-transfer effect is greater than direct injection, but the water cooler internal resistance is larger, thereby is only applicable to the cooling of large specification steel, and cooling uniformity is not good.The nozzle core of spiral-flow type cooler is comprised of the ommatidium by constant slope of arranging in the form of a ring, and the cooling water that therefore surrounds steel is to spray in the shape of a spiral, thereby heat-transfer intensity is stronger, and cooling uniformity is better, is applicable to the steel cooling of all size.
The common shortcoming of above-mentioned three kinds of water coolers is that the nozzle circumferential weld is non-adjustable, thereby can only rely on the valve regulated water yield, hydraulic pressure on the water cooler water inlet pipe, in case water shortage, water cooler is not fully filled, just will produce the inhomogeneous cooling phenomenon, in case because iron sheet, foreign material have stopped up water cooler, disassembly, cleaning are also relatively more difficult.
Summary of the invention
Technical problem to be solved by this invention provides a kind of adjustable ring-shaped spiral-flow type cooling method, to solve the uncontrollable problem of circumferential weld size of water cooler in the prior art.
The technical solution adopted for the present invention to solve the technical problems is: a kind of adjustable ring-shaped spiral-flow type cooling method is provided, water is entered in the ring cavity between water cooler seat and the water cooler core by the inlet opening, the water curtain that ejects is enclosed in steel to be cooled on every side with its cooling, by regulating to the left or to the right the position of water cooler core, size that can the adjusting water outlet circumferential weld, after the adjusting, tighten fixing by anti-loose-back cap; Water forms the water curtain of first via ring-type by the ejection of the circumferential weld between water cooler seat and the water cooler core; Water forms the water curtain of the second tunnel rotation shape by the aperture ejection of water cooler core front end; When the water cooling tube front end did not fill loudspeaker and chews, the steel direction of motion that is cooled was consistent with water (flow) direction; When front end was loaded onto loudspeaker and chewed, the steel direction of motion that is cooled was opposite with water (flow) direction.
A kind of cooler that uses adjustable ring-shaped spiral-flow type cooling method, formed by rotatable water cooler core, water cooler seat, water cooling tube, water cooler core front end has the oblique aperture of a circle, link to each other with thread between water cooler core and the water cooler seat, and fix with anti-loose-back cap, described water cooling tube is fixed on the water cooler seat with bolt, packing ring.
Beneficial effect
Characteristics of the present invention are that the circumferential weld size is adjustable, can change flexibly the water yield and the hydraulic pressure of water cooler, and the dismounting cleaning is also more convenient.Simultaneously, two kinds of water curtains cross, and produce stronger turbulent flow, have not only strengthened heat-transfer effect, and have improved the uniformity of steel coolings.

Wherein: 1-water cooler core, 2-prevents the loose-back cap, 3-water cooler seat, the 4-water cooling tube, the 5-loudspeaker are chewed.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
A kind of adjustable ring-shaped spiral-flow type cooling method, its flow process as shown in Figure 1, after the size of having determined required water outlet circumferential weld, unclamp anti-loose-back cap 2, by regulating to the left or to the right the position of water cooler core 1, the size of adjusting water outlet circumferential weld, after the adjusting, tighten fixing by anti-loose-back cap 2.
As shown in Figure 2, water is entered in the ring cavity between water cooler seat 3 and the water cooler core 1 by the inlet opening, from the ejection of the circumferential weld between water cooler seat 3 and the water cooler core 1, forms the water curtain of first via ring-type; Water forms the water curtain of the second tunnel rotation shape by the aperture ejection of water cooler core 1 front end, and two kinds of water curtains cross, and is enclosed in steel to be cooled and makes its cooling on every side.
Such as Fig. 2, when water cooling tube 4 front ends do not fill loudspeaker and chew 5, are forward type water coolers, the steel direction of motion that is cooled is consistent with water (flow) direction; Are reverse type water coolers when front end loads onto that loudspeaker chew 5, the steel direction of motion that is cooled is opposite with water (flow) direction.
