Abstract
The utility model discloses a narrow-surface copper plate structure for a thin-slab caster mould, belongs to the technical field of continuous casting equipment and is used for solving the problems that the mould has high corner cooling strength, may easily form a thicker corner for a shell and the like. A working surface on the narrow surface of the mould is a concave cambered surface; five cooling pipelines are longitudinally arranged in the narrow surface of the mould; and the axes of the five cooling pipelines are collinear in the transverse direction of the narrow surface of the mould. In the utility model, the narrow-surface copper plate structure of the mould is optimally designed, the working surface used is the concave cambered surface, and the reasonably arranged cooling pipelines are matched, so the corner cooling speed is effectively slowed down and the difference between the thickness of the shell at the corner and the thickness of the middle shell is reduced to ensure that the shell can meet the technical requirements. The design of the structure meets the cooling form of a casting blank in the mould, ensures the thickness of the casting blank when the casting blank is discharged from the mould and is in favour of improving the surface quality of the casting blank and prolonging the service life of the narrow-surface copper plate of the mould.
Description
Technical field
The utility model relates to a kind of cast steel equipment, especially for the leptoprosopy structure of thin-slab caster crystallizer, belongs to the continuous casting installation for casting technical field.
Background technology
Continuous casting steel machine (continuous casting) is the technology that the molten steel continuously cooling and freezing is become strand, and crystallizer is to be the core component of strand with the molten steel crystallization in the continuous casting installation for casting.The thin-slab caster crystallizer adopts combining form usually, as shown in Figure 3: be made up of two wide copper coins 4 and two narrow copper plates 1.At present, the working face of the narrow copper plate of thin-slab caster crystallizer mostly is single tapering leptoprosopy or many taperings leptoprosopy (vertical working face vertical profile sees that working face is many taperings), these two kinds of crystallizer narrow copper plates are all according to strand strand vertical contraction situation design in crystallizer in process of setting, and two kinds of narrow copper plates in use can satisfy strand in contraction longitudinally by regulating online tapering.But in cooling procedure because leptoprosopy bight, strand both sides be a two dimension cools off, intensity of cooling is big, cause base shell bight thicker, more serious to the wearing and tearing of crystallizer narrow copper plate limit portion, make crystallizer narrow copper plate wearing and tearing bigger, and strand goes out behind the crystallizer because the base shell is thicker, causing fan-shaped section to depress difficulty, to cause fan-shaped section to be pressed not in place, strand attenuate difficulty also causes defectives such as the mashed limit of coiled sheet easily.
The utility model content
The utility model is used to overcome the defective of prior art and a kind of cooling form of strand in crystallizer that meet is provided, and guarantees the thin-slab caster crystallizer narrow copper plate structure of slab thickness when strand goes out crystallizer.
The alleged problem of the utility model is that following technical scheme solves:
A kind of thin-slab caster crystallizer narrow copper plate structure, its special feature is: the working face of described crystallizer narrow copper plate is the cambered surface of indent, in the crystallizer leptoprosopy, vertically be provided with five cooling lines, at the crystallizer leptoprosopy axis conllinear of five cooling lines transversely along it.
Above-mentioned thin-slab caster crystallizer narrow copper plate structure, described crystallizer leptoprosopy working face arc surface radius R is 200-270mm, the cooling line axis in the middle of described being positioned at and the distance L at working face center are 28.1-21.1mm.
The utility model causes crystallizer bight intensity of cooling big at present crystallizer for continuous casting of thin slabs narrow copper plate structure, easily cause the thicker problem in base shell bight to improve, crystallizer narrow copper plate structure has been carried out optimal design, its working face adopts the cambered surface of indent, the cooling line that cooperates reasonable disposition, effectively slow down crystallizer bight cooling velocity, reduce the bight shell thickness, make the base shell can satisfy technological requirement with the gap between the intermediate blank thickness of the shell.Design of the present utility model meets the cooling form of strand in crystallizer, guarantees the slab thickness when strand goes out crystallizer, helps improving the service life of cc billet surface quality and crystallizer narrow copper plate.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the sectional drawing in Figure 1A-A cross section;
Fig. 3 is a thin-slab caster crystallizer schematic diagram.
Label is expressed as follows in the accompanying drawing: 1. crystallizer narrow copper plate; 2. working face; 3. cooling line; 4. wide copper coin of crystallizer.
The specific embodiment
The utility model improves thin-slab caster crystallizer narrow copper plate structure, as shown in Figure 1 and Figure 2: the high cambered surface in low both sides in the middle of the working face 2 of described crystallizer leptoprosopy 1 adopts, in the crystallizer leptoprosopy, vertically be provided with five cooling lines 3 along it, these five the relative crystallizer leptoprosopy of cooling line cross central lines are symmetrically distributed, and at the crystallizer leptoprosopy axis conllinear of five cooling lines transversely.This design is far away to the distance of cooling line because of crystallizer leptoprosopy both sides, helps slowing down the bight cooling velocity, and it is thicker, serious and influence problem such as slab quality to the wearing and tearing of crystallizer leptoprosopy limit portion to eliminate base shell bight.
Referring to Fig. 2, crystallizer leptoprosopy working face arc radius size R is that 200-270mm is advisable, and the cooling line in the middle of described being positioned at and the distance L at working face center are that 28.1-21.1mm is advisable.
Claims (2)
1. the bad conticaster crystallizer narrow copper plate of thin plate structure, it is characterized in that: the working face (2) of described crystallizer narrow copper plate (1) is the cambered surface of indent, in the crystallizer leptoprosopy, vertically be provided with five cooling lines (3), at the crystallizer leptoprosopy axis conllinear of five cooling lines transversely along it.
2. thin-slab caster crystallizer narrow copper plate structure according to claim 1, it is characterized in that: described crystallizer leptoprosopy working face arc surface radius R is 200-270mm, and the cooling line axis in the middle of described being positioned at and the distance L at working face center are 28.1-21.1mm.
