Abstract
The utility model discloses a copper plate crystallizer which is formed by assembling two opposite wide-face copper plates and two opposite narrow-face copper plates. The copper plate crystallizer is characterized in that the narrow-face copper plates are narrow-face chamfered copper plates, working faces, making contact with molten steel, of the narrow-face chamfered copper plates comprise two chamfered faces and a working face body between the two chamfered faces, the inner surface of the longitudinal profile of the working face body is a first curve from an upper opening to a lower opening of the crystallizer in a smooth transition mode, and the contour lines of the chamfered faces and the working face body on the upper opening and the lower opening of the crystallizer are straight lines respectively. By means of the arrangement, the performance of the crystallizer is optimized.
Description
Technical field
The utility model relates to field of iron and steel smelting, is specifically related to the copper coin crystallizer in a kind of casting process.
Background technology
Continuous casting technology, since occurring, has been one of industrial technology with fastest developing speed in steel industry, and it has the production technology of simplification, increases recovery rate of iron, reduces energy consumption, improves working conditions, and improves the advantages such as slab quality.But on the current technology, continuous casting crystallizer for plate billet can only be for pouring into a mould the slab of fixed dimension casting blank section, and pouring type is single.If want, realize the cast of billet production process, must change mould assembly, its cost will increase.Because the development of current whole metallurgy industry is depressed, the state that Ge great steel mill even loses in meagre profit, the increase of equipment cost will make the production of steel mill drop into burden.Meanwhile, when continuous casting steel billet section is excessive, can bring the problems such as bulge, crackle, affect the further raising of pulling rate.
Utility model content
The purpose of this utility model is to propose a kind of copper coin crystallizer;
For reaching this object, the utility model by the following technical solutions:
A kind of copper coin crystallizer, by two relatively wide copper coin narrow copper plates relative to two, fit together and form, it is characterized in that: described narrow copper plate is leptoprosopy chamfering copper coin, the working face that described leptoprosopy chamfering copper coin contacts with molten steel comprises the working face between two fillet surfaces and two fillet surfaces, described working face longitudinal profile inner surface is suitable for reading from crystallizer is the first line smoothing transition to end opening, and fillet surface and working face are straight line at crystallizer outline line suitable for reading and at the outline line of end opening; Described crystallizer is also provided with the mouth of a river, the described mouth of a river forms with horizontal segment by vertical section, described vertical section comprises annular sidewall, described annular sidewall is prepared from by refractory material, this annular sidewall forms the mouth of a river first half and middle part, the mouth of a river, mouth of a river Lower Half forms horizontal segment, offers water hole, mouth of a river opened upper end on described annular sidewall; The mouth of a river first half is funnel ring body, middle part is cylinder ring body; Near symmetry on the sidewall of the cylinder ring body at middle part, have three water holes, all and intracavity inter-connection, three water holes are all angle of inclination with horizontal direction for three water holes; On the sidewall near above bottom, be arranged with a contralateral exposure, two side holes is connected with hollow lumen; The wall of side opening surrounding extends to horizontal direction, is positioned at mouth of a river Lower Half and forms described horizontal segment, and described horizontal segment one end of every side is connected with vertical section, other end bottom sealing, top perforate, and institute's perforate and vertical direction are angle of inclination.
As preferably, the 8%-22% that the length of the outline line that narrow copper plate fillet surface is suitable for reading is thickness of strand.
As preferably, described fillet surface and the angle between working face are 142-172 degree.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model crystallizer;
Wherein: 1 leptoprosopy chamfering copper coin; Working face between 2 leptoprosopy chamfering copper coin fillet surfaces; 3 fillet surfaces; 4 fillet surfaces; 5, the outline line at 6,7 crystallizer places suitable for reading; 8, the outline line at 9,10 crystallizer end opening places.
The specific embodiment
A kind of copper coin crystallizer, by two relatively wide copper coin narrow copper plates relative to two, fit together and form, it is characterized in that: described narrow copper plate is leptoprosopy chamfering copper coin, the working face that described leptoprosopy chamfering copper coin contacts with molten steel comprises the working face between two fillet surfaces and two fillet surfaces, described working face longitudinal profile inner surface is suitable for reading from crystallizer is the first line smoothing transition to end opening, and fillet surface and working face are straight line at crystallizer outline line suitable for reading and at the outline line of end opening; Described crystallizer is also provided with the mouth of a river, the described mouth of a river forms with horizontal segment by vertical section, described vertical section comprises annular sidewall, described annular sidewall is prepared from by refractory material, this annular sidewall forms the mouth of a river first half and middle part, the mouth of a river, mouth of a river Lower Half forms horizontal segment, offers water hole, mouth of a river opened upper end on described annular sidewall; The mouth of a river first half is funnel ring body, middle part is cylinder ring body; Near symmetry on the sidewall of the cylinder ring body at middle part, have three water holes, all and intracavity inter-connection, three water holes are all angle of inclination with horizontal direction for three water holes; On the sidewall near above bottom, be arranged with a contralateral exposure, two side holes is connected with hollow lumen; The wall of side opening surrounding extends to horizontal direction, is positioned at mouth of a river Lower Half and forms described horizontal segment, and described horizontal segment one end of every side is connected with vertical section, other end bottom sealing, top perforate, and institute's perforate and vertical direction are angle of inclination.The length of the outline line that narrow copper plate fillet surface is suitable for reading is 12% of thickness of strand.Described fillet surface and the angle between working face are 162 degree.
