Description
Technical field
The utility model belongs to steel corrosion detection technique field, is specifically related to a kind of for the pick-up unit with rust steel sample rusty scale compactness extent.
Background technology
The corrosion phenomenon of steel component is ubiquitous, and the waste of material caused thus and economic loss are also inestimable.Hold corrosion-prone problem in an atmosphere to solve steel, people have developed weathering steel.Hinder corrosive medium to contact matrix because weathering steel surface can generate stable fine and close protective rust, reduce corrosion speed, be therefore widely used.And the rusty scale that steel surface is formed is loose easily comes off, and there is micro-crack to exist, therefore can not play a protective role to matrix.In actual applications, many steel constructions (as bridge, container etc.) will bear certain load, as the vibrations of vehicle by producing during bridge, and the collision etc. that container produces in handling process.If the rusty scale on steel surface is fine and close not, in actual military service process, rusty scale just easily ftractures, and makes rusty scale localised protection action deprivation, and iron and steel occurs again to corrode.So can weathering steel generate fine and close rusty scale in corrosion environment, has great significance to corrosion stability.
The rusty scale of the stable densification that naked steel corrosive nature under atmospheric environment mainly relies on surface to be formed is protected matrix, thus hinders corrosive medium contact matrix to realize.The evaluation of current people to rusty scale compactness extent mainly contains electrochemical process, corrosion product analysis method, rusty scale Mechanics Performance Testing and rusty scale freeze-thawing method etc.
Paper " W450QN steel atmospheric corrosion performance " (corrosion and protection [J], 2011,32 (4): 305-307), electrochemical process is adopted to carry out polarization curve test to the atmospheric exposure band of 3 years rust sample, the compactness of rusty scale is judged by tieing up blunt current density, tie up blunt current density less, illustrate that its rusty scale is fine and close, rusty scale barrier propterty better.But the method needs to inlay sample before carrying out corrosion test, electrochemical test can not be carried out to the normal tape sample that becomes rusty, therefore there is limitation.
Paper " mechanical property of Protective Rust Layer Formed on Surface of Weathering Steel Panels " (steel research journal [J]; 2006; 18 (3): 42-45), cutting is carried out to band rust sample and inlays sanding and polishing, adopt ultra microhardness instrument to carry out impression test to rusty scale xsect.Because the method is also need cutting, rusty scale is thus easily made to crack.
Publication number CN102866104A discloses one " evaluation method based on the weathering steel rusty scale protective capability of freeze-thawing process "; adopt freeze-thawing method process weathering steel rusty scale; produce the change of rusty scale crackle; utilize scanning electron microscope to observe, thus evaluate the compactness extent of weathering steel rusty scale.The method mainly resists the ability of frost or dew to the impact of rusty scale for north cold area rusty scale, has limitation; And the method carries out that freeze-thawing required time is longer, process is loaded down with trivial details, and needs to utilize scanning electron microscope to judge, test that can not be quantitative, result is affected by human factors greatly.
Summary of the invention
It is simple that the utility model aims to provide a kind of structure, is easy to safeguard, sample is without the need to cutting and inlay, and fast, accurately, quantitatively can detect the device of normal tape rust sample rusty scale compactness extent.
For this reason, the solution that the utility model is taked is:
A kind of band rust steel sample rusty scale compactness extent pick-up unit, comprises base, pillar, base, body, regulating sleeve, chuck, weight, drift and spring; Base, by shore supports base, is fixed with the body of surface band scale above base, body side axially has one lifting groove; Be provided with weight in body, weight top is fixed with handle by connecting link, and connecting link is placed in lifting groove; " H " shape regulating sleeve with draw-in groove in the middle of one is slidably socketed outside body, an annular chuck is flexibly connected in regulating sleeve draw-in groove, with gap on chuck, regulating sleeve side is provided with slot with lifting groove correspondence position, regulating sleeve is fixed on body by adjustment screw, one "T"-shaped drift is housed below weight, and on the plunger rod of four-prism, cover has spring, and lower spring end card is placed in the bore of the punch chuck in the middle of base.
Described weight weight is 0.5 ~ 3kg.
Described tube surfaces scale is 0 ~ 300mm.
The using method of the utility model band rust steel sample rusty scale compactness extent pick-up unit is:
Produce at least 2 steel grades, each steel grade 3 pieces of plane plate specimens carry out contrast detect.One of them sample is placed on pick-up unit base.Rotary chuck, chuck gap is overlapped with regulating sleeve slot, unclamp adjustment screw, after regulating sleeve being adjusted to setting height, locking adjusts screw, after again the weight chosen being raised to regulating sleeve slot upper end, rotary chuck makes chuck gap and regulating sleeve slot stagger, and makes weight be fixed on desired height.When dropping hammer, rotary chuck makes its gap overlap with regulating sleeve slot, and weight falls naturally, drift lower end pressing in sample rusty scale surface.Promote weight to regulating sleeve slot upper end by handle, rotary chuck, fixes weight.Take out sample, measure two diagonal line crack lengths of sample rusty scale surface squares impression, calculate two diagonal line crack length sums, and record.Detect respectively by above-mentioned steps and calculate two diagonal line crack length sums of all the other each samples, after averaging by steel grade, more different steel grade mean value, length shorter explanation sample rusty scale is finer and close, otherwise then loosens.
The beneficial effects of the utility model are:
The utility model structure is simple, be easy to safeguard, band rust sample used is without the need to cutting processing, can directly test, and can quantitative comparison rusty scale compactness extent, choose weight and the pendency height of weight as required, carry out the test of different impulsive force, detect result fast, its influence factor is few, and testing result is more stable.
