Description
Technical field
The present invention relates to a kind of continuous casting installation for casting, and in particular to a kind of billet caster clamping roll-type is three sections fan-shaped.
Background technique
Continuous casting is one of the key link of iron and steel enterprise's quality control, and efficient, low consumption produces flawless high-quality slab
It is the productive target of conticaster.Currently, during large square bland continuous-casting machine continuous casting, since the steel grade of production is more, purposes ratio
Relatively wide, alloying element is more complex, and bulge phenomenon occurs in slab, reduces slighter compress effect, slab center porosity, center occurs
The defects of shrinkage cavity, center segregation, middle crack.
Specifically, slab, in process of setting, the unstability of slab heat transfer leads to column crystal speed of growth speed not
One, the column crystal of preferred growth meets to be formed " bridging " at slab center, and molten steel is separated, crystal brige by " solidification crystal brige " in liquid core
The molten steel of lower part cannot get the molten steel supplement on top in solidification shrinkage and form loose or shrinkage cavity, and with center segregation；Casting
Latter stage is also solidified, ot-yet-hardened is enriched with the molten steel flow of segregation element (C, S, P), is moved in the molten metal of ot-yet-hardened, this
A little easily segregation elements are enriched to slab center or solidification end region, thus generate center segregation and loose.In addition, slab is sent out
When raw bulge deformation, bulge amount is bigger, and center segregation is more serious.
Three sections of the sector of current conticaster generally only outer arc carrying roller and side arc guiding, production section high-carbon high-quality is special
When steel, secondary cooling water cooling requirement takes weak cold mode, and temperature drift when slab being caused to enter three sections fan-shaped, casting blank shell is relatively
Thin, in wide face bulge scene can occur for slab under green shell interior liquid ferrostatic pressure operation.Therefore, it is impossible to solve slab drum
Tripe problem, and because of the internal soundnesses problem such as slab center porosity caused by casting blank bulging.
Summary of the invention

Dummy bar top bad niproll or carrying roller guarantee equipment safety operation.
Carrying roller is additionally provided in the braced frame, the carrying roller is located on slab progress path after outer arc leading truck
Side, and it is located at the end of braced frame.
The carrying roller and the extrados of the arc base shape control area are in the same arc surface of slab progress path
On.The operation with supporting casting blank and flexible dummy bar is kept by carrying roller.
The braced frame has the support plate for being located at two sides and the cooling-water duct being formed between two panels support plate.
Entire braced frame is cooled down by cooling water.
The two sides of the upper roller and lower roll all have rotary joint, access cooling water by rotary joint, in upper roller under
Cooling water path is formed inside roller.
The utility model has the advantages that three sections of the sector pass through and niproll are arranged on the support frame, by under the outer arc on niproll
The arc base shape control area for controlling square billet base shape is collectively formed between roller and the upper roller of inner arc, when slab passes through the region
When, effective control to the wide dough shape of slab realized by the cooperation of upper roller and lower roll, thus the effective solution wide face of slab
Bulge problem, slab is scrapped caused by avoiding because of bulge.
