Abstract
The utility model discloses a foot roll for a novel continuous casting crystallizer, which comprises a roll body and a shaft hole, wherein the roll body is an abnormal roll body which is wide in the middle part and thin in both ends. The foot roll can reduce the line contact length between the casting blank and the foot roll, reduce the possibility of the water accumulation between the circular arc surface of the foot roll and the casting blank and eliminate the phenomenon that the casting blank is immersed in the accumulated water, thereby avoiding the additional forced cooling of the casting blank, lowering the nonuniformity of cooling the casting blank, reducing the deformation amount of the casting blank and improving the qualified ratio of products.
Description
Technical field
The utility model relates to a kind of continuous casting installation for casting parts, particularly a kind of novel continuous cast mold foot roller.
Background technology
Crystallizer is the critical component that improves casting machine main product rate and slab quality as the capital equipment of conticaster.The outlet of crystallizer main body is provided with sufficient roller and cool water shower device, carries out the cooling of two cold-zone initial parts.Strand has cooling water to cool off by sufficient roller section the time.For line contacts, form sealing between down in theory between strand and the sufficient roller, forming sulculus between arc surface and the strand on the sufficient roller.Owing to splash or flow in the sulculus after the cool water shower, form ponding, make this section of strand bubble in ponding, strand is formed extra pressure cooling, the inhomogeneities of aggravation strand cooling causes the casting blank deformation amount to increase, and causes defectives such as strand easily cracks simultaneously.
Therefore, need transform, reduce on the sufficient roller formation chance of ponding between the arc surface and strand, stop the strand bubble in ponding, thereby avoid strand to form extra pressure cooling sufficient roller.
The utility model content
In view of this, the purpose of this utility model provides a kind of novel continuous cast mold foot roller, the formation chance of ponding in reducing on the sufficient roller between the arc surface and strand, stop the situation of strand bubble in ponding, thereby avoid strand to form extra pressure cooling, alleviate the inhomogeneities of strand cooling, reduce the casting blank deformation amount, improve product percent of pass.
Novel continuous cast mold foot roller of the present utility model comprises the body of roll and axis hole, and the described body of roll is the thin special-shaped body of roll in middle thick two.
Further, the thick thin part of part and two is cylinder in the middle of the described body of roll;
Further, the thick thin part of part and two is cylinder in the middle of the described body of roll;
Further, thick part accounts for 1/3 of whole barrel length in the middle of the described body of roll;
Further, the big 50mm of diameter of the part that the diameter of thick part is thinner than two in the middle of the described body of roll.
The beneficial effects of the utility model are: novel continuous cast mold foot roller of the present utility model, the thin sufficient roll structure in thick two in the middle of adopting, reduce strand and sufficient roller line contact length, the formation chance of ponding in reducing on the sufficient roller between the arc surface and strand, stop the situation of strand bubble in ponding, thereby avoid strand to form extra pressure cooling, alleviate the inhomogeneities of strand cooling, reduce the casting blank deformation amount, improve product percent of pass; Thick portion of the body of roll and thin portion adopt cylindrical structure, can play the effect of normal location to strand, can also reduce the contact amount simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is the utility model structural representation.
The specific embodiment
Accompanying drawing is the utility model structural representation, as shown in the figure: the novel continuous cast mold foot roller of present embodiment, comprise the body of roll 1 and axis hole 2, the body of roll 1 is the thin special-shaped body of roll in middle thick two; The thick thin part 12 of part 11 and two is cylinder in the middle of the body of roll 1; Thick part 11 accounts for 1/3 of whole barrel length in the middle of the body of roll 1; Thick part 11 accounts for 1/3 of whole barrel length in the middle of the body of roll 1; The big 50mm of diameter of the part 12 that the diameter of thick part 11 is thinner than two in the middle of the body of roll 1.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
