Description
Technical field
The utility model relates to a kind of dendrite corrosion metallographics to detect rubbing down integration apparatus, belong to detection ancillary equipment technology
Field.
Background technique
Dendrite corrosion macroscopic examination method is the development with continuous casting technology and the continuous casting billet macroscopic examination method to become better and approaching perfection day by day.
Compared with the macroscopic examinations method such as traditional sufur printing and hot acid erosion, it not only can accurately show the internal flaw of continuous casting billet, and
And the solidified structure of continuous casting billet can also be clearly displayed.This is just further analysis slab defects and the phase between solidified structure
Pass information, the approach for seeking improvement continuous casting billet quality and measure create advantage.
It is electrochemical process to the corrosion in test check face that dendrite, which corrodes macroscopic examination method, is shown by medical fluid corrosion
The inhomogeneities of specimen surface.In electrolyte solution, metal surface different zones have different electrode potentials, are formed a large amount of
Micro cell, the lower area of current potential is that anode dissolves, and the higher area of current potential is precipitated for cathode.Metal and alloy
The current potential of crystal boundary is usually lower than intra-die, is the anode of micro cell, so corrosion is first since crystal boundary.Metal and alloy
The segregation generated when solidification is also the reason of causing electrochemical nonuniformity, therefore dendrite corrosion macroscopic examination method can be shown
The presence of segregation defects.
Before dendrite corrosion experiment, need to carry out sample polishing grinding, existing polishing grinding needs to be detected with hand-held
Sample is polished on sand paper, and the dust after polishing spills into working environment, has biggish injury to the respiratory tract of personnel.
And in the step of specimen surface polishes, needs man-hour manually hand-held to be detected test specimens and polished on high speed polishing disk, due to
Tested test specimens are smaller, are easy to fly out in polishing disk upthrow light, and there are some potential safety problemss, for this purpose, designing a kind of safety
The good polishing grinding equipment of protective is of great significance to the safety for improving experiment.
Summary of the invention

There is sample 60, extension arm 20 is provided on workbench 11,20 one end of extension arm is provided with driving motor 21,21 lower section of driving motor
Shaft is connected with polishing disk 22, and draught hood 30 is additionally provided on workbench 11, and 30 side of draught hood offers logical for extension arm 20
The exhausting cover opening 301 crossed, on draught hood 30 according to distinguished and admirable flow direction be disposed with corrugated flexible hose 32, wind chamber connecting pin 33,
Wind chamber 34 and cyclone separator 40,34 bottom of wind chamber are provided with the first garbage collection storehouse 35, and cyclone separator 40 wraps
Air inlet 41 and air outlet 42 are included, blower 44 is provided on cyclone separator 40,40 bottom of cyclone separator is provided with
Two garbage collection storehouses 43.
Sample 60 to be polished is fixed on specimen holder 15 in above scheme, and draught hood 30 is then placed into sample 60
Around, then extension arm 20 is extend into draught hood 30, starts to carry out sample 60 sanding and polishing, polishing by polishing disk 22
The dust of generation is by there is corrugated flexible hose 32 to enter in wind chamber 34, and the dust of heavier mass is in the first garbage collection storehouse 35
It is once settled, lighter dust will enter in cyclone separator 40 with distinguished and admirable, and in the second garbage collection storehouse 43
Second of sedimentation of interior completion, subsequent air-flow are discharged from air outlet 42.
(such as it can be due to needing persistently to provide coolant liquid to the buffed surface of sample during the polishing process and use water as cold
But liquid), therefore the dust generated of polishing can be mingled with steam and enter in wind chamber 34, dust group of being easy under wet environment
Gather together, therefore collect dust in the first garbage collection storehouse 35 to keep in the position of orlop, will not with it is distinguished and admirable into
Enter into cyclone separator 40.After entering cyclone separator 40, according to the principle of cyclonic separation, most of dust
Grain can be deposited to the second garbage collection storehouse 43.
