Description
Technical field
The invention belongs to continuous casting steel billet identification technology fields, more particularly, to a kind of quick identification method of continuous cast round billets.
Background technique
It, need to be to steel billet in order to carry out follow-up of quality management and provide bloom production process tracing basis in continuous casting
It is identified work --- letter and number combinatorics on words, to indicate the contents such as heat (batch) number, tank number, steel grade code name, stream number and steel billet number,
Once quality problems occur, date of production can be traced according to mark, heat (batch) number, lot number and corresponding material situation and its
His related data, to search problem and solving the problems, such as to provide reliable help.Continuous cast round billets are as seamless steel pipe, big swaged forging
Part primary raw material, transport flow through the clarity identified in journey, accuracy is related to subsequent product processing technology and quality.
Conventional identification operation be by mode of manually writing or label, but at present continuous cast round billets transport mainly use water transport,
Traffic condition is relatively poor, and phenomena such as transportational process easily causes mark to obscure, fall off, therefore common identification method is unable to satisfy
The mark of continuous cast round billets needs.The way for doing numeral mark to round billet in industry is, after the casting blank stacking wait need to identify is cooling,
Carry out the cold mark of section again according to data markers, however, this mode identification cycle is long at present, the stacking cooling waiting time makes long
It is big at quantity in stock, production flowing is constrained, and not can guarantee the integrality of mark during transportation still.
Therefore, how to ensure round billet mark quickly, it is accurate, prevent from falling off, shorten process cycle as continuous cast round billets mark
It is badly in need of solving critical issue.
Summary of the invention
It is an object of the invention to propose a kind of quick identification method of continuous cast round billets, the mark for being directed to continuous cast round billets at present is solved
Deficiency existing for knowledge mode improves marking effect, shortens identification cycle, ensures the integrality of mark.
In order to achieve the above object, the present invention uses following technical scheme：
A kind of quick identification method of continuous cast round billets comprising following steps：
1) continuous cast round billets of well cutting are moved on cold bed, checks slab information, confirmation steel grade, specification, heat (batch) number and slab
Tracking system is consistent, and updates character on spray number plate；
2) slab reaches spray region on cold bed, removes the iron scale that casting blank section generates；
3) number plate face casting blank section is sprayed, heat-resisting paint is sprayed, by character spray printing on casting blank section；
4) casting blank stacking is cooled to assigned temperature, smears protective coating in casting blank section, is applied to form one layer of protection
Layer.
Wherein, when spray, the surface temperature of slab is 400 DEG C~600 DEG C.
Wherein, 700 DEG C of heat-resisting paint high temperature resistant.
Wherein, the assigned temperature of slab cooling is 50 DEG C~150 DEG C.
Wherein, protective coating is by varnish and solvent or diluent according to 2:1 proportion composition.
Wherein, heat-resisting paint is sprayed using spray rifle, and AEI After End of Injection will spray number plate, spray rifle is put in impregnate in water and prevent
It is dry.
Wherein, spray number plate is made of sub- board and female board, and female board is arranged according to casting blank cross-section size, and sub- board is provided on female board
Insert port, sub- board are combined by several letters, number and/or spcial character.
To sum up, the quick identification method of continuous cast round billets provided by the invention combines pyrolytic coating with antifreezing protection technique,
Instead of the production method identified again after original equal cooling, spray process is not influenced by slab waste heat and is shifted to an earlier date,
So as to shorten identification cycle, and protect process to identify forming effect is more preferable, keeps timeliness more long, mark, which is not easy to lose, to be known
It does not spend, solves the problems, such as of the existing technology, meet higher production requirement.
Specific embodiment
The technical scheme of the invention is further explained by means of specific implementation.
Present embodiments provide a kind of quick identification method for continuous cast round billets comprising following steps：
Step 1: the continuous cast round billets of well cutting are moved on cold bed, check slab information, confirmation steel grade, specification, heat (batch) number with
Slab tracking system is consistent, and updates character on spray number plate.To guarantee that character can accurately reflect the slab information.
Step 2: slab reaches spray region on cold bed, the iron scale that casting blank section generates is removed.It is understood that general
Continuous cast round billets surface temperature is between 400 DEG C~600 DEG C, and traditional handicraft needs the cooling such as stacking that could reprocess, so that product
Accumulating amount is big, poor fluidity, and the method does not have to take slab waste heat into account, directly carries out section cleaning using angle grinder, can wait
To be painted number.
Step 3: spray number plate face casting blank section, sprays heat-resisting paint, by character spray printing on casting blank section.Herein
Heat-resisting paint is a kind of metallic high temperature coating, and high temperature resistant is sprayed up to 700 DEG C using spray rifle, without scrupling slab table
Face temperature influences mark forming effect.It should be noted that AEI After End of Injection will spray number plate, spray rifle is put in water and impregnates, this
Spray number plate can be effectively prevented for sample and spray rifle is counter does.
Step 4: casting blank stacking is cooled to assigned temperature, protective coating is smeared in casting blank section, is prevented to form one layer
Protect coating.Assigned temperature herein is preferably 50 DEG C~150 DEG C, and due to the progress of preceding processes, slab temperature has been gradually decreased,
When to this step, the stacking time is greatly decreased, and the amount of hoarding will not be too many.After being cooled to above-mentioned temperature range, reusing hairbrush will
Protective coating is uniformly applied to casting blank section, carries out character protection, and section may make to identify clearly, without discoloration.Protection herein
It is varnish that coating, which forms primary raw material, and varnish and solvent or diluent proportion are 2:1.
In addition it supplements, the spray number plate of use is made of sub- board and female board, and female board is according to the big little makings of casting blank section, on female board
Sub- board insert port is reserved, sub- board is combined by several letters, number and/or spcial character, sub- board exists according to slab information
Combination is installed, such spray number plate production is simple, changes convenient for information on female board.
To sum up, the quick identification method of continuous cast round billets in the embodiment combines pyrolytic coating with antifreezing protection technique,
Instead of the production method identified again after original equal cooling, spray process is not influenced by slab waste heat and is shifted to an earlier date,
So as to shorten identification cycle, and protect process to identify forming effect is more preferable, keeps timeliness more long, mark, which is not easy to lose, to be known
Do not spend, solve the problems, such as it is of the existing technology, mark quick and precisely, the process-cycle is short, meets higher production requirement.
The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present invention
Limitation.
