Abstract
The invention discloses a novel rectangular casting blank section. The corner of a rectangular casting blank or a square casting blank is designed into a big fillet, and the radius of the fillet is 20 to 25 percent of the thickness of the casting blank. When the casting blank reaches the position of a withdrawal and straightening unit and is pressed down, because of the effect of geometric dimension of the fillet, the two solidified sides are prevented from being pressed down, and the middle part of the casting blank is easily pressed down, so that obvious light pressing effect is achieved with low pressure, and the light pressing efficiency is greatly improved. The light pressing purpose is fulfilled by using the conventional withdrawal and straightening unit. The required power consumption is reduced, and meanwhile, normal operation of a steel-push heating furnace, operation of the casting blank on a roller table and stability of cogging rough-rolling pass rolling are ensured. Meanwhile, because of the design of the big-fillet casting blank, the casting blank is well cooled in primary cooling and secondary cooling processes of continuous casting, internal corner cracks of the casting blank are effectively prevented, and the cooling effect of the casting blank is close to that of a round billet.
Description
Technical field
The present invention relates to a kind of casting blank section, specially referring to the corner is a kind of novel rectangular casting blank section of fillet.
Background technology
In casting process, use and gently depress the loose and shrinkage cavity that alleviates solidification end, the inherent quality tool that improves continuous casting billet is had certain effect.During strand is in solidification end, on the position of straightening machine, its realization is depressed, existing gently depressing all is to use straight barrel that the square billet or the rectangular bloom on plane are depressed, because the strand both sides had been frozen into solid-state base shell already, so need the drafts that the bigger power of depressing just can reach to be needed, corresponding liquid core organizes the strand mid portion to be depressed distortion fully, reaches the requirement of gently depressing.
Just because of the effect of two solid-state base shells in side, implementing to make it produce plastic deformation when gently depressing, caused the very big power of depressing, the straightening machine has been proposed higher requirement, need very big hydraulic pressure.The back depressed by the straightening machine because the effect of strain, the amount that strand is certain with resilience, thus reduced the effect of depressing, on the straightening machine, must use bigger drafts to adapt to.
In sum,, need a kind of novel rectangular casting blank section especially, to solve the deficiencies in the prior art at the defective of prior art.
Summary of the invention
The object of the present invention is to provide a kind of novel rectangular casting blank section, be designed to big fillet by corner with rectangular casting blank or square strand, thereby realized adopting less pressure to obtain the effect of significantly gently depressing, improved the efficient of gently depressing greatly, can also prevent effectively that simultaneously strand inner corners crackle from taking place, near with the cooling effect of circle base.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of novel rectangular casting blank section is characterized in that the corner of described section is designed to fillet, and the radius of fillet is the 20%-25% of slab thickness.
In one embodiment of the invention, the straightening function is directly depressed the SMIS position of strand, reaches to adopt less pressure to obtain the effect of obviously gently depressing.
In one embodiment of the invention, in the cooling procedure of strand, be provided with the process of once cooling and secondary cooling, reach the effect of approaching circle base cooling in conjunction with the design of fillet.
In one embodiment of the invention, when strand is gently depressed, adopt integral planar to depress, effectively avoid resilience.
In one embodiment of the invention, described section length and wide scope are the 150-500 millimeter.
In one embodiment of the invention, the long-pending decline of casting billet surface that causes owing to fillet can solve by increasing the strand physical dimension.
The present invention is by being designed to big fillet by the corner with rectangular casting blank or square strand, thereby realized adopting less pressure to obtain the effect of significantly gently depressing, improved the efficient of gently depressing greatly, can also prevent effectively that simultaneously strand inner corners crackle from taking place, near with the cooling effect of circle base.
Description of drawings
Fig. 1 is the profile of a kind of novel rectangular casting blank section of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, a kind of novel rectangular casting blank section of the present invention, be that rectangular bloom or square billet are designed to a big fillet, general copper tube design adopts about 4% radius of corner of thickness direction size, the design has reached the 20-25% of slab thickness, technical scheme of the present invention can be used at the 150mm square billet up to the 500mm square billet, on the various rectangular blooms.Such as for the 200mm square billet, fillet is 40mm.When arriving the straightening seat in the plane, puts when depressing strand, because the effect of the physical dimension of fillet, avoided depressing in the both sides of having solidified, be easy to the SMIS position of strand is depressed, thereby realized adopting less pressure to obtain the effect of significantly gently depressing, improved the efficient of gently depressing greatly.Simultaneously, prevented that effectively strand inner corners crackle from taking place because the design of big fillet strand makes it obtain cooling preferably in a cold-peace two cold processes of continuous casting, near with the cooling effect of circle base.Because the long-pending decline of casting billet surface that big fillet causes can solve by suitable increase physical dimension.
Strand is realized gently depressing, elastic recovery after needing to consider to depress, if use conventional whole plane to depress, two sides must will solidifying obtain bigger plastic deformation, adopt the scheme of this big fillet, the reaction of depressing of strand is solidified solid phase area in the side of making an appointment with half.A main middle part of only using lower hydraulic pressure to act on wide of foundry goods has significantly reduced having solidified depressing of both sides base shells, and network is in the molten steel of solidification end and implements effectively extruding, reaches the desirable purpose of gently depressing.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
