Abstract
The utility model relates to a novel square billet conticaster dummy bar, the bottom surface of dummy bar head recess comprises straight face and inclined plane, and the crossing department on straight face and recess facade, straight face and inclined plane is transition fillet structure. The utility model discloses changed the traditional design form of dummy bar, made the molten steel even in the recess of dummy bar head, cooled off fast, reduced the danger of bleed-out.
Description
Technical field
The utility model relates to a kind of cast steel equipment, has particularly related to a kind of novel billet caster dummy bar.
Background technology
Dummy bar is the common equipment in the cast steel process, the dummy bar head is provided with groove, the profile bottom of tradition dummy bar groove is swallowtail trough structure, in order to take off ingot smoothly, the dovetail groove rear design becomes arc structure, but dummy bar is in drawing the process of steel, and limit portion cools off fast and inner the cooling slowly, cause strand to lift up, the security incident that ingot is taken off in easy generation automatically owing to inhomogeneous cooling forms.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of novel billet caster dummy bar is provided, and this dummy bar head adopts new design, effectively avoided strand since inhomogeneous cooling and on the phenomenon of lifting up, ensured the safety of producing.
In order to address the above problem, the utility model by the following technical solutions:
A kind of novel billet caster dummy bar, the bottom surface of dummy bar head groove is formed by facing directly with the inclined-plane, faces directly with groove facade, the intersection faced directly with the inclined-plane to be the knuckle structure.
Described face directly and the groove facade between the knuckle radius be R
1, R
1Be 5～20mm.
The described knuckle radius of facing directly with the inclined-plane is R
2, R
2Be 40～60mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model has changed the traditional design form of dummy bar, face the arc surface of bottom portion of groove directly with the inclined-plane combination instead, alleviated and drawn the fluctuation of strand in the dummy bar groove in the steel process, reduced the danger of bleed-out.
Description of drawings
Fig. 1 is the utility model cross-sectional view;
Fig. 2 is the dummy bar head cross-sectional view before improving.
The specific embodiment
A kind of novel billet caster dummy bar, as shown in Figure 1, the bottom surface of dummy bar head 1 groove by face directly 2 and inclined-plane 3 form, face directly 2 with the groove facade, face directly 2 and the intersection on inclined-plane 3 be the knuckle structure.Face directly 2 and the groove facade between the knuckle radius be R
1, R
1Be 5～20mm, face directly 2 and the knuckle radius on inclined-plane 3 be R
2, R
2Be 40～60mm.
Embodiment 1: by the strand diagnosis refrigeration, be the dovetail groove rear section radius that the excessive circular arc of 200mm changes into and faces 2 and the combination on inclined-plane 3 directly, R
1For 5mm, the long L of facade are 140mm, R
2Be 40mm.
Claims (3)
1, a kind of novel billet caster dummy bar is characterized in that, the bottom surface of dummy bar head groove is formed by facing directly with the inclined-plane, faces directly with groove facade, the intersection faced directly with the inclined-plane to be the knuckle structure.
2, a kind of novel billet caster dummy bar according to claim 1 is characterized in that, described face directly and the groove facade between the knuckle radius be R
1, R
1Be 5～20mm.
3, a kind of novel billet caster dummy bar according to claim 1 is characterized in that, the described knuckle radius of facing directly with the inclined-plane is R
2, R
2Be 40～60mm.
