Description

Technical Field

[0001] The invention belongs to the field of steel macrostructure and defect detection equipment, and in particular relates to a mobile steel macrostructure and defect cold etching device. Background Art

[0002] With the naked eye or with a low-power magnifying glass, we can observe the obvious defects such as looseness, segregation, bubbles and shrinkage cavity residues, inclusions, white spots, etc. on bars, wire rods and billets. The defects detected by macroscopic inspection are called low-power structural defects of steel. At present, despite the advanced instruments and methods for steel quality inspection and judgment, low-power structural defect inspection is still widely used in production practice because it is simple and direct.

[0003] With the development of modern steel industry, rapid detection of the internal quality of continuous casting billets has become increasingly important. The cold etching method for low-power structure and defects of steel is widely used in major steel production industries due to its advantages of simple operation and low detection cost. However, in the detection process of this method, chemical waste liquid is difficult to collect, causing environmental pollution, and the volatilization of cold etching liquid can easily cause damage to the human respiratory tract. Summary of the invention

[0020] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] The invention discloses a mobile steel macrostructure and defect cold etching device, such as Figure 1 As shown, it includes: a billet cold etching plate 1, a waste liquid placement plate 2, a waste liquid tank 3, a drain pipe 12, a bracket 4, and a universal wheel 5. The billet cold etching plate 1 is horizontally arranged, and the billet cold etching plate 1 is recessed downward to form a cold etching groove 11 for holding the cold-etched steel billet. A first through hole is opened at any corner and the central position of the cold etching groove 11. The waste liquid placement plate 2 is horizontally arranged and located directly below the billet cold etching plate 1. The waste liquid tank 3 is a closed container, and the waste liquid tank 3 is placed on the waste liquid placement plate 2.

[0022] A second through hole is provided on the top of the waste liquid tank 3, and the waste liquid tank 3 is used to hold the waste liquid flowing out of the cold etching tank 11. The upper end of the drain pipe 12 passes through the first through hole to be connected with the cold etching tank 11, and the lower end of the drain pipe 12 passes through the second through hole to be connected with the waste liquid tank 3. The drain pipe 12 is used for the waste liquid in the cold etching tank 11 to flow out from top to bottom to the waste liquid tank 3. The bracket 4 is vertically arranged, and the bracket 4 is a frame. The bracket 4 is used to accommodate the steel billet cold etching plate 1 and the waste liquid placement plate 2. The bracket 4 is fixedly connected to the steel billet cold etching plate 1 and the waste liquid placement plate 2 on all sides. The universal wheel 5 is installed on the lower side of the waste liquid placement plate 2. The universal wheel 5 is used to drive the entire device to move. There are four universal wheels 5, and they are all lockable universal wheels, which can be easily moved to the desired position and locked and fixed.

[0023] A magnet is installed on the vertical inner wall of the cold etching tank 11, and a brush and / or a water scraper 9 is adsorbed on the magnet by magnetic force. The magnet on the cold etching tank 11 can suspend and adsorb the brush and the water scraper 9 on the side wall of the cold etching tank 11, which is conducive to the brush and the water scraper 9 to drain, and can make full use of the space for fixed placement. The scraper of the water scraper 9 is made of acid and alkali resistant rubber, which can quickly scrape off the flushing liquid on the surface of the sample and has a magnet embedded at the root, which can be adsorbed on the magnet on the side wall of the cold etching tank 11.

[0024] The first through hole of the cold etching groove 11 is opened at the corner and the center of the cold etching groove 11. The first through hole opened at the corner is convenient for concentrated discharge of residual liquid by the water scraper 9, and the first through hole opened in the center is convenient for a large amount of residual liquid to be discharged and enter the waste liquid tank 3 located below the cold etching groove 11.

[0025] Any edge of the cold etching groove 11 extends laterally to form a receiving table, and the receiving table is recessed downward to form a receiving groove 6 for placing multiple inclined gaskets 10. Each inclined gasket 10 is a triangle and is used to level the steel billet in the cold etching groove 11. Each inclined gasket 10 is connected to the bracket 4 by a rope. The inclined gasket 10 is made of acid-base material and is used to adjust the level of the sample detection surface to prevent uneven distribution of the cold etching liquid from affecting the detection results.

[0026] A drain valve 7 is installed on the side wall of the waste liquid tank 3. The drain valve 7 is arranged close to the bottom of the waste liquid tank 3. The waste liquid valve is at a certain distance from the bottom of the waste liquid tank 3, which is conducive to the precipitation of impurities after neutralization and prevents clogging of the sewer; the sealing of the waste liquid tank 3 can be achieved by equipping the upper part with a box cover to prevent the waste liquid from volatilizing.

[0027] Any edge of the cold etching tank 11 extends transversely to form a placement table, and the placement table is recessed downward to form a circular placement groove 8 for placing multiple solvent bottles. The placement groove 8 can be used to place reagents and flushing liquid containers required for the test.

[0028] Example 1

[0029] Step 1: Place the prepared steel billet sample test surface upward and flat in the cold etching tank 11, push the present invention under the fume hood, use the inclined gasket 10 to pad under the sample and adjust it to make the sample test surface horizontal, use a brush to dip the cold etching reagent, and brush it evenly on the sample test.

[0030] Step 2: After the organization and defects are clear, rinse the sample surface with a rinse solution and scrub it with a brush. After completion, pull the present invention out of the fume hood and use a water scraper 9 to scrape off the liquid on the sample surface, then use an electric blower to blow dry before image acquisition and rating work can be carried out.

[0031] Step 3: Take out the sample and put the inclined gasket 10 back to its original position, use the water scraper 9 to collect the residual liquid to the first through hole at the corner of the cold etching tank 11 and let it flow into the waste liquid tank 3 to complete this test.

[0032] Step 4: When a certain amount of chemical waste liquid is collected in the waste liquid tank 3, add a neutralizing agent into the waste liquid tank 3 from the first through hole at the corner of the cold etching tank 11 to neutralize the waste liquid, open the waste liquid valve to release a small amount of waste liquid into the container, test it with pH test paper until it reaches neutrality, then open the waste liquid valve, and the neutralized waste liquid flows into the sewer, take out the waste liquid tank 3 to clean the impurities precipitated at the bottom.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
