Description
Technical field
The utility model relates to a kind of continuous casting crystallizer copper plate, and particularly one laterally with longitudinally becomes convexity continuous casting crystallizer copper plate.
Background technology
Crystallizer is the parts of most critical in conticaster, its performance plays a very important role the production capacity of conticaster and slab quality, and copper plate of crystallizer is direct and steel contacts heat exchange, in order to ensure under high as far as possible pulling rate along crystallizer periphery base shell homoepitaxial, continuous casting billet is made to have good surface quality, base shell in crystallizer is needed to try one's best and copper plate of crystallizer close contact, considered that the solidification shrinkage of initial solidification shell in crystallizer produced air gap and hinders heat transfer in the past, general employing arranges certain taper to make up the generation of air gap along on throwing (longitudinal direction) direction at narrow face copper plate of crystallizer, develop single tapering thus, the type crystallizers such as many taperings and parabola taper, but the design of these crystallizers only considered along shrinking law on throwing direction for the impact of shell growth, and do not consider that transversely air gap is for the impact of shell growth in crystallizer, by finding the actual measurement of a large amount of slab bleed-out base shell, within the scope of the portion 30mm-50mm of Kuan Mian drift angle, crystallizer exit, base shell is the thinnest, easily produce the defects such as the even longitudinal line of surface indentation splits herein and affect cc billet surface quality, this is owing to transversely contacting comparatively tight with crystallizer wall owing to being subject to ferrostatic pressure in Kuan Mian center at strand, heat exchange amount large base shell is thicker, and although strand bight is shunk comparatively early, and air gap is larger, but bight belongs to Two-Dimensional Heat, it is not base shell thinnest part, the position that base shell is the thinnest appears at drift angle portion hotspot location, therefore be necessary to consider that base shell cross-direction shrinkage rule designs a copper plate of crystallizer and caves in the base shell solving drift angle portion hot zone and easily produce and the defect such as longitudinal crack.
Summary of the invention
One of the purpose of this utility model is that providing a kind of laterally with longitudinally becomes convexity continuous casting crystallizer copper plate, continuous casting billet drift angle portion hot zone can be avoided easily to produce the generation of base shell depression and longitudinal crack phenomenon, contribute to improving the surface quality crystallizer strand.
the utility model solves the technical scheme that its technical problem adopts:
The utility model comprises: wide copper coin and narrow copper plate, and the two ends of described wide copper plate working surface, a certain position at close top are risen, are laterally respectively equipped with the convexity conical camber extended to bottom.
The total length of described convexity conical camber is the 2/3-1/2 of length of mould, and the starting point on convexity conical camber summit is positioned at crystallizer edge position, and convexity conical camber bottom terminal place is an arc-shaped curved surface, at the lowermost end of wide copper coin.
Described arc-shaped curved surface is made up of three sections of tangent circular arcs, wherein the camber line of two ends circular arc and the horizontal flat segments of copper coin tangent, be 60 mm-100 mm with flat segments two point of contact spacing.The arc height of middle circular arc is 0.1mm-3 mm apart from copper coin flat segments height.Wherein: the conical camber of described band convexity effectively can make up the air gap transversely produced in base shell solidification shrinkage process in crystallizer.
The casting blank section width that the copper plate of crystallizer that described wide copper coin and narrow copper plate are formed is suitable for is 600mm-3000mm, thickness 120mm-300mm.
Described wide copper coin and narrow copper plate can assembledly be dismantled, the copper plate of crystallizer of formation.
Described wide copper coin comprises extrados copper coin and intrados copper coin.
Described narrow copper plate working face is surface plate or single tapering, many taperings or parabola taper.
Described wide copper coin and narrow copper plate are all dispersed with longitudinal bosh.
the beneficial effects of the utility model are:
The utility model laterally has Design of Crown respectively by the two ends edge at wide copper plate working surface, the solidification shrinkage rule of base shell in crystallizer can be agreed with, improve the inhomogeneous growth of the base shell that heat transfer inequality that the wide face of continuous cast mold transversely causes because of the generation of air gap causes, the blemish such as the depression of elimination crystallizer base shell drift angle portion hotspot location and line split, improve continuous casting billet quality.
