Abstract
The invention discloses a nickel-chromium-iron alloy seamless tube. The nickel-chromium-iron alloy seamless tube is prepared from the components: nickel, copper, manganese, carbon, silicon, sulphur, chromium, aluminum and the balance of iron and is prepared from the steps of: (1) inspecting a blank firstly; (2) carrying out first acid pickling on the blank; (3) carrying out coping treatment on the blank after first acid pickling; (4) carrying out lubrication, cold drawing and rolling, degreasing by virtue of acid pickling, heat treatment, acid pickling and coping on the blank; (5) judging whether the requirements of a finished product are satisfied or not, and repeating the fourth step if the requirements are not satisfied; (6) if the requirements are satisfied, carrying out shaping, straightening, acid pickling, sizing processing and flaw detection on the blank; and (7) finally, marking and warehousing the finished product. The nickel-chromium-iron alloy seamless tube has the functions of resistance to corrosion, high temperature, strong acid and strong alkali, and is saving in cost.
Description
Technical field
The present invention relates to a kind of manufacturing of seamless tube, be specifically related to the nichrome seamless tube that a kind of UNS NO6601 alloy is made.
Background technology
Seamless tube is a kind of circle that hollow section, periphery do not have seam that has, and is square, the rectangle steel.Seamless tube is to make hollow billet with steel ingot or the solid pipe hole that wears long, and makes through hot rolling, cold rolling or cold group then.Seamless tube has hollow section, a large amount of pipelines as conveyance fluid, steel pipe is compared with solid steel such as round steel, when the bending resistance twisting strength is identical, weight is lighter, be a kind of economic cross-section steel, be widely used in manufacturing structure spare and mechanical component, as steel scaffolding of using in oil drill rocker, truck drive shaft, bicycle frame and the building operation etc.
At aspects such as some high temperature, the mineral acid that is mixed with impurity and organic acid (as formic acid and acetic acid), corrosive environment of sea water, general pipe can't widespread use in this environment, and maintenance cost is bigger, can't promote on a large scale.
Therefore, the seamless tube of research and develop a kind of corrosion-resistant, high temperature resistant, anti-strong acid, anti-highly basic, saving cost is problem demanding prompt solution.

Description of drawings
Fig. 1 be a preferred embodiment of the present invention process flow diagram.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
Of the present invention is a kind of nichrome seamless tube, referring to shown in Figure 1, described nichrome seamless tube comprises by weight percentage: nickel is 58%-63%, and copper is 0.06%-0.1%, and manganese is 0.6%-1%, carbon is 0.07%-0.13%, silicon is 0.44%-0.67%, and sulphur is 0.009%-0.015%, and chromium is 21%-25%, aluminium is 1%-1.7%, and the iron of surplus.
The manufacturing step of described nichrome seamless tube is:
(1) at first blank is tested,
(2) then blank is carried out the pickling first time,
(3) the good blank of the pickling first time is carried out reconditioning and handles,
(4) to blank be lubricated, cold drawing and rolling, pickling deoil, thermal treatment, pickling and reconditioning are handled,
(5) judge whether to satisfy finished product, as not being repeating step 4 then,
(6) then carry out shaping aligning, pickling, scale processing and flaw detection in this way and handle,
(7) at last finished product is identified warehouse-in.
Further specify, described Acidwash solution is formed by hydrofluoric acid and nitric acid hybrid modulation, the composition of the pickle solution in the described Acidwash solution comprises that mass percent is that nitric acid and the mass percent of 11%-13% is the hydrofluoric acid of 2.3%-5.5%, described lubricant is made of butter and lime, concrete weight ratio is butter: lime=2:8.5, the scope of the rolling technological parameter deflection of described cold drawing and rolling is 1.3%-1.5%, and described heat-treatment temperature range is 940 ℃-1180 ℃.
