Below in conjunction with accompanying drawing, the utility model is described further.
Double-current different section slab caster of the present utility model, comprise two stream cast strand equipment and cooling twice width cutting apparatus, as shown in Figures 2 to 4, two stream cast strand equipment comprise light section crystallizer 1, light section bending section 2, light section fan-shaped section 3, big cross section bending section 4, big cross section fan-shaped section 5, large-section crystallizer 6, movable mould 7.Every first-class arc equipment can select to install light section crystallizer 1 respectively, light section bending section 2 combines with light section fan-shaped section 3; Light section crystallizer 1, big cross section bending section 4 combine with big cross section fan-shaped section 5; Large-section crystallizer 6, big cross section bending section 4 combine with big cross section fan-shaped section 5.When only needing wherein first-class work, then adopt movable mould 7 will not pour into a mould region pans lumen loading.
As shown in Figures 2 to 4, cooling twice width cutting apparatus of the present utility model comprises outer arc edge cooling control loop 11, outer arc center cooling control loop 12, inner arc edge cooling control loop 13, the cooling of inner arc center control loop 14, outer arc edge nozzle 15, outer arc central nozzle 16, inner arc edge nozzle 17, inner arc central nozzle 18, whether water flowing controls outer arc edge cooling control loop 11 pairs of outer arc edge nozzles 15, makes the nozzle water yield in the reasonable scope.
In conticaster production process, the molten steel flowed out from the tundish bottom mouth of a river is successively through crystallizer (primary cooling zone), spraying pool (secondary cooling zone) and natural cooling zone (three cooling zones), its heat scatters and disappears gradually and finally solidifies out into strand completely, and the utility model is for secondary cooling zone.Whether water flowing controls outer arc center cooling control loop of the present utility model 12 pairs of outer arc central nozzles 16, makes the nozzle water yield in the reasonable scope; Whether water flowing controls inner arc edge cooling control loop 13 pairs of inner arc edge nozzles 17, makes the nozzle water yield in the reasonable scope; Whether water flowing controls inner arc center cooling control loop 14 pairs of inner arc central nozzles 18, makes the nozzle water yield in the reasonable scope; Wherein outer arc edge nozzle 15, outer arc central nozzle 16, inner arc edge nozzle 17, inner arc central nozzle 18 are sprayed water to the section casting blank in production process respectively according to demand.The utility model adopts cooling twice width blanking method, and when can prevent from producing section casting blank, edge is crossed cold and produces corner crack.And can also reduce water consumption like this, when at utmost ensureing again to produce different section strand, surface temperature control in the reasonable scope, effectively improves slab quality
.
Light section crystallizer 1 cross-sectional sizes of the present utility model is (180,200) mm × (700 ~ 1000) mm, light section bending section 2 cross-sectional sizes is (180,200) mm × (700 ~ 1000) mm, light section fan-shaped section 3 cross-sectional sizes is (180,200) mm × (700 ~ 1000) mm, big cross section bending section 4 cross-sectional sizes is (150 ~ 300) mm × (1100 ~ 2100) mm, big cross section fan-shaped section 5 cross-sectional sizes is (150 ~ 300) mm × (1100 ~ 2100) mm, and large-section crystallizer 6 cross-sectional sizes is (150 ~ 300) mm × (1100 ~ 2100) mm.
(180,200) mm indicates and selects these two points of 180mm, 200mm herein, and (700 ~ 1000) mm represents continuous print numerical value in selection 700mm to 1000mm.
In process of production, two stream cast casting blank sections are different, then casting metal guiding device is not identical, adjusts wide ability because width difference is too large considerably beyond crystallizer itself, thus need to change crystallizer, bending section, fan-shaped section only supporting casting blank prevent bulge plant equipment can be general.But for when preventing from producing light section strand, edge is crossed cold and produced corner crack, the utility model have employed secondary cooling water, gas jets width incision technology see Fig. 1.
See Fig. 2, according to the production schedule, wherein first-class installation light section crystallizer 1, light section bending section 2, light section fan-shaped section 3, first-class installation light section crystallizer 1, big cross section bending section 4, big cross section fan-shaped section 5 in addition, utilize perfect head interchangeability, separate unit casting machine two can be realized and flow and produce little slab simultaneously.
See Fig. 3, according to the production schedule, wherein first-class installation light section crystallizer 1, light section bending section 2, light section fan-shaped section 3, first-class installation large-section crystallizer 6, big cross section bending section 4, big cross section fan-shaped section 5 in addition, can realize the little slab of first-class production, and the first-class on-line width adjustment technology that utilizes can produce slab in (150 ~ 300) mm × (1000 ~ 1500) mm in addition.
See Fig. 2, Fig. 3, when double-current slab is produced simultaneously, pans inner chamber full symmetric, various flow control device optimum configurations is reasonable, can improve inclusion floating condition, improves molten steel temperature uniformity.
See Fig. 4, according to the production schedule, only first-class installation large-section crystallizer 6, big cross section bending section 4, big cross section fan-shaped section 5, output demand can be met according to during the calculating of stove machine coupling known only single current cast sheet slab, thus remaining X flows middle pot drainage opening needs closedown not pour into a mould, this will inevitably cause fluidity molten steel to decline, X flowing water mouth freezeout is caused for avoiding sprue gate and the molten steel excessive temperature differentials of closing between the mouth of a river in pans, thus need to adopt movable mould 7 will not pour into a mould region pans lumen loading, single current can be realized and produce (150 ~ 300) mm × (1100 ~ 2100) mm sheet slab.
Under the condition taking technical scheme to maintain secrecy, from this composite pouring technology on October 09th, 2013, formal certain factory at home comes into operation so far, add up to water steel 1,200,000 t, successively 2 streams produced the little slab of 200 × 860,200 × 800,200 × 740,200 × 700,200 × 940 simultaneously; Also slab in the once little slab of the 1st stream cast 200 × 860 the 2nd stream cast 200 × 1250 simultaneously; Also once only single current produced 200 × 1600 sheet slabs, and strand inside and outside is superior in quality, can according to market situation, and flexible organization is produced, and practical effect is satisfactory.
