Abstract
The utility model relates to a high pressure water pipe nozzle for removing scales on the inner surface of a seamless steel tube, in particular to a high pressure water pipe nozzle used by a discharge roller way at back of a walking beam reheating furnace and the inlet section of a walking beam cooler on removing the scales on the inner surface of the online steel tube. A nozzle body is a cylinder with a lug boss, a through hole is arranged in the axis of the nozzle body, one end of the through hole is close to the lug boss and is provided with a conical water inlet, and the other end of the through hole is provided with a conical water outlet. During the process of removing the scales on the inner surface of the hot-rolled seamless steel tube, the high pressure water sprayed by the nozzle to the tail inner hole and head inner hole of the steel tube can completely reach the inner surface of the steel tube and radically remove the scales on the inner surface of the hot-rolled seamless steel tube.
Description
Technical field
The utility model relates to the nozzle on a kind of high-pressure water pipe, particularly a kind of high-pressure water pipe nozzle that uses when the walking beam cooler inducer is removed the inner surface oxidized iron sheet of line Pipe that reaches on the furnace delivery table of step-by-step movement reheating furnace back.
Background technology
Development along with the steel pipe industry, the user requires more and more higher to tube quality, particularly high pan pipe, the user proposes to remove epoxy iron sheet in the steel pipe, the purpose one of removing epoxy iron sheet in the steel pipe is to prevent that in order to check the steel pipe internal-surface quality, to the more important thing is interior iron scale from peeling off the back blocking pipeline.The method of epoxy iron sheet is to adopt the pickling of steel pipe off-line, ball blast, inner surface reconditioning in the existing removing steel pipe.And inner surface reconditioning, ball blast opposing outer face are very difficult, and efficient is also very low, and often class of an equipment can only reconditioning 3～5, in the steel pipe's production that so not only the extended cycle, has increased the steel pipe's production cost again; Pickling inner surface effect is not good yet, and the peracid corrosion phenomenon is arranged, and is influential to pipe quality.
Steel pipe is adopted the removing of online inner surface oxidized iron sheet, be on the furnace delivery table of step-by-step movement reheating furnace back and the walking beam cooler inducer is removed the inner surface oxidized iron sheet of line Pipe, the method for removing is to remove the iron scale of steel pipe internal-surface by the water under high pressure that the nozzle on the high-pressure water pipe sprays into certain flow to steel pipe afterbody endoporus and head endoporus.Adopt this method to remove the iron scale of steel pipe internal-surface, reduced steel pipe rear portion finishing procedure, not only saved the cost of pickling, ball blast, reconditioning but also improved production efficiency.
The water under high pressure that sprays into certain flow to steel pipe afterbody endoporus and head endoporus by the nozzle on the high-pressure water pipe is removed the iron scale of steel pipe internal-surface, and the design of nozzle is very crucial.Because steel pipe has certain length, designs of nozzles is bad, and the water under high pressure of nozzle ejection can not arrive steel pipe internal-surface fully, and the effect of removing the steel pipe internal-surface iron scale is just bad.
Summary of the invention
The purpose of this utility model provides a kind of high-pressure water pipe nozzle that is used to remove the hot rolled seamless steel tube inner surface oxidized iron sheet.
The technical solution of the utility model is: a kind of high-pressure water pipe nozzle of removing the hot rolled seamless steel tube inner surface oxidized iron sheet, the body of nozzle is the cylinder of a band boss, be provided with a through hole in the axle center of body, through hole end by boss is provided with a conical water inlet, and the other end of through hole is provided with a conical delivery port.
To the steel pipe of difference, select the nozzle of different size for use when internal diameter.When pipe diameter during greater than 150mm, select for use in the big flow setting-out and in the setting-out nozzle steel pipe internal-surface is carried out the online oxidation iron sheet that removes; When pipe diameter during, select for use low discharge water under high pressure and hydraulic spray that steel pipe internal-surface is carried out the online oxidation iron sheet that removes less than 150mm.
Setting-out and low discharge water under high pressure are meant the flow and the pressure of water in the described big flow, and the setting-out of middle setting-out is less than water under high pressure.
Setting-out nozzle and hydraulic spray are meant the size of nozzle endoporus in described, and the endoporus of middle setting-out nozzle is greater than the endoporus of hydraulic spray.
The high-pressure water pipe nozzle that the utility model provides has following characteristics: in the process of removing the hot rolled seamless steel tube inner surface oxidized iron sheet, nozzle can arrive steel pipe internal-surface fully to the water under high pressure that steel pipe afterbody endoporus and head endoporus spray into, and thoroughly removes the iron scale of hot rolled seamless steel tube inner surface.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
