Description
Technical field
The present invention relates to high-pressure water jet normal temperature descaling process technical field, specifically refer to a kind of nozzle for high-pressure water jet normal temperature descaling process.
Background technology
Steel in heating process, ferro element generation oxidation reaction and diffusion in the oxygen in furnace gas, carbon dioxide, moisture etc. and steel top layer, surface forms a large amount of iron scales.For lower road cold-drawn operation, carry out the surface scale removal, i.e. the Rolled steel descaling technology.Current domestic de-scaling generally adopts the traditional handicrafts such as pickling, ball blast, and spent acid and waste gas serious environment pollution that pickling produces, more and more be subject to the restriction of national environmental protection.The dust pollution that ball blast produces is also very serious, and causes steel tube surface table shape that a lot of pockmarks is arranged, and equipment investment is large, and operating cost is high.And adopt the Mould of High Pressure Water Abrasive Jet method to remove steel surface firecoat method, and because the overall cost of its de-scaling is low, and there is no industrial pollution, so attract wide attention, the research at this to the abrasive water jet flow nozzle enters critical stage.Hybrid mode research by water under high pressure and abrasive material at present has various ways, there is kind of internal-mixing nozzle to adopt abrasive material to mix with water under high pressure under high pressure conditions, then from nozzle, spray together, this type of nozzle wear is serious, and because water under high pressure has very high flow rate, abrasive material can't enter into the water jet centre, and mixed effect is not ideal, and service efficiency is not high.Also having kind of an outer mixed mode nozzle is after adopting water under high pressure to spray at a high speed, with the low pressure abrasive material, mix again, this type of nozzle is with several strands of high-speed water jets, with certain angle, aloft cross, and abrasive flows is passed at center, at junction point and water jet, force to converge, usually outer mixed mode nozzle mixes for abrasive material, and nozzle wear is less, adopts the superhard alloy integrated formed structure, after such structure causes the higher and nozzle of the cost of nozzle to damage, integral body is scrapped, and is unfavorable for that industrial production controls cost.
Summary of the invention
The present invention is directed to the above-mentioned deficiency of prior art, a kind of nozzle for high-pressure water jet normal temperature descaling process reduced costs when guaranteeing the results of use such as abrasive material mixes, and nozzle wear is less is provided.
Technical scheme of the present invention is: a kind of nozzle for high-pressure water jet normal temperature descaling process, it comprises and is provided with at least one for first import of advancing water under high pressure and a nozzle body that is provided with the second import for advancing the husky mixed liquor of low-pressure water, it also comprises the first nozzle core, second nozzle core and clamp nut, described the first nozzle core is provided with at least two triple feed inlets of being made by carbide alloy and entering for water under high pressure and one for advancing the 4th import of the husky mixed liquor of low-pressure water, the inner peripheral wall of described second nozzle core is provided with hard alloy layer, described the first nozzle core, the second nozzle core, clamp nut and nozzle body are demountable structure.
Can find out that according to such scheme the present invention has following advantage: when the husky mixed liquor of water and water under high pressure enter in nozzle, the nozzle easily place of wearing and tearing concentrates on the triple feed inlet of the first nozzle core and water under high pressure and the husky mixed liquor meet of water of second nozzle core, these two places wearing and tearing are the most serious, so the ejection of the triple feed inlet from water under high pressure from the first nozzle core and the inner-wall material of the husky mixed liquor meet of water of second nozzle core are all adopted to super wearable hard alloy; Simultaneously whole designs of nozzles is dismountable structure, so, when the first nozzle core or second nozzle core go wrong, can be changed arbitrarily.So nozzle of the present invention is inlayed super wearable hard alloy being easy to abrading section, both can guarantee not easy to wear under high-pressure situations and mix, can increase service time by Cost reduction again, and dismounting is safeguarded also very convenient.
As preferably, described demountable structure refers to the first nozzle core and nozzle body clamping, the upper end of described second nozzle core and the first nozzle core offset and with the nozzle body clamping, described clamp nut and nozzle body are spirally connected; Such structure can be so that enter at high-pressure fluid structural stability and the wearability that nozzle guarantees nozzle, and remove also suitable convenience.
As preferably, the direction of described the 4th import vertically and respectively with the second import, the concentricity line of second nozzle core; Such design can be so that abrasive material be lower to the wearing and tearing of nozzle.
As preferably, the inwall aperture of the upper end of described second nozzle core from top to bottom diminishes gradually; After such structure makes the husky mixed liquor of water mix in nozzle with water under high pressure when spraying from nozzle pressure further promote, the better effects if of de-scaling.
