Description
Technical field
The utility model relates to metal freezing and continuous casting field, particularly a kind of combination mould copper coin with longitudinal fluting.
Background technology
In modern metallurgical production technology, the continuous development and progress of continuous casting technology shows that mainly the steel grade of can casting constantly enlarges, and some high-carbon, high alloy, high-quality steel grade are constantly produced in the continuous casting production procedure of large-scale iron and steel enterprise.The development of especially big section casting blank continuous casting technology is to the compression ratio requirement increase of steel, to the internal soundness requirement raising of steel product.But because the existence of process of setting choosing part crystallization rule, the adverse effect of bringing in the big section casting blank production process of high alloy, high-carbon steel is exactly the center segregation of strand and loosens, to such an extent as to it is to cause high alloy, the tired defective in high-carbon steel center that the basic reason of fracture takes place.
In order to overcome the harm that high alloy, high-carbon steel center segregation bring to steel military service performance, the metallargist has carried out number of research projects for many years, developed a series of control solidification technology, what this was wherein main has two: the one, and electromagnetic agitating technology comprises crystallizer electromagnetic agitation, solidification end electromagnetic agitation etc.It is under lower molten steel overheat condition, and the center equiaxial crystal ratio by increasing strand is to reach the purpose that reduces the strand center segregation.But, practical application effect shows: the center equiaxial crystal ratio that improves strand is fairly obvious to the center segregation of strand and the improvement of loosening, but it does not reach desired effect, the even not evitable sometimes generation that also can cause V-shaped segregation and white band.
At the problems referred to above, the metallargist has developed solidification end again and has gently depressed technology in recent years, and it has been widely used in the continuous casting production of square billet, rectangular bloom, slab, and improve the strand center segregation and loose aspect played positive effect.The adjustment of people by drafts can be so that the strand center reaches zero segregation, even negative segregation.But in the bloom that the width large rectangle base close with thickness even width and thickness equate is produced, because segregation occurs over just in the very little zone of strand core, this zone to be rolled and close, and the solution of segregation is extruded, must be rolled whole big section base.Like this, not only need the bigger power of depressing, and less drafts can not be delivered to the strand core fully, but need be than heavy reduction.Bigger drafts causes solidification front extension deflection to increase, and this is to cause the solidification end interdendritic to depress the basic reason that crackle produces.China's document " improving the measure of little square billet internal soundness " (literature reference: Liu Xin. continuous casting, 2009, (4), p36～39) by optimizing continuous casting process, the strand internal soundness is improved.China's document " bloom continuous casting is dynamically gently depressed the technology application study " (literature reference: Yang Subo, Chen Yong, Li Guijun. iron and steel, 2005,40(6), p24-26) gently depress process system and improved strand center segregation, loose and shrinkage cavity by adjusting.
In the existing technology, production rectangular bloom, billet continuous casting crystallizer have only two kinds: the one, and tubular type rectangular bloom, square blank crystallizer, two is four plate combined type rectangular bases, square blank crystallizer.But on the whole, their strands of producing all are rectangles or square.
China utility model patent CN102554155A, title " tube type mold " provides a kind of square billet tube type mold, and the strand that adopts above-mentioned technology to produce is rectangular bloom or square billet.These strands are being carried out solidification end when gently depressing, will produce inevitably that the power of depressing is big, solidification end easily produces problems such as depressing crackle.
Summary of the invention
The combination mould copper coin that provides a kind of with longitudinal fluting of the present invention, it can save casting-rolling force, improves the segregation effect significantly, avoids depressing the interdendritic crackle that distortion causes simultaneously.
To achieve these goals, the utility model is by the following technical solutions:
A kind of combination mould copper coin with longitudinal fluting, this combination mould copper coin comprises four working face copper coins, be respectively a pair of wide the copper coin and a pair of narrow copper plate of positioned opposite, wherein: four working face copper coins are dismountable connection, wide copper coin is extrados copper coin 1 and intrados copper coin 2, narrow copper plate is two side cambered surface copper coins 3,4, on cross section arbitrarily, at the zone line of intrados copper coin 2 and/or extrados copper coin 1, an outwards outstanding longitudinal fluting 5 is arranged from top to bottom; Be distributed with a plurality of boshes on each working face copper coin 1,2,3,4.

Width L, the depth H of described longitudinal fluting 5 diminish to end opening gradually from the suitable for reading of combination mould copper coin, and suitable for reading and ratio end opening is 1.03～1.35.
Described longitudinal fluting 5 is selected from the longitudinal fluting 9 of platform-like, arcuation or the longitudinal fluting 12 of multilayer step shape.
The longitudinal fluting of described platform-like is made up of 7,8 of the transition regions on neutral straight district 6 and both sides, two width of transition zone D be respectively longitudinal fluting 5 overall width L 20%～60%.
Described outer, wall thickness such as inner arc working face copper coin 1,2 is or wall thickness such as non-.
Described bosh is vertical tank 10 or vertical water hole 11.
Each angle α of described longitudinal fluting 5 is the obtuse angle, and the angle at α angle is 95 °＜α＜170 °, and the top of each angle α is the circular arc R smooth transition of 5～2000mm with radius during use.
The outline of the combination mould copper coin of described band longitudinal fluting is the arc that is applicable to the arc casting machine; Or be applicable to the straight shape of straight type casting machine.
The casting blank section that described combination mould copper coin is suitable for is wide 120～1000mm, thick 120～600mm.
The beneficial effects of the utility model are: strand depress the liquid core place that deflection can directly affact solidification end, improved the center segregation of strand effectively; And owing to the colder strand of strand the right and left does not deform, so the required power of depressing is also seldom, the deflection that strand extends is also very little, the generation that also just can effectively avoid depressing crackle.
