Abstract
The utility model provides a crystallizer broadside copper plate for an efficient slab caster and relates to continuous casting crystallizers. The crystallizer broadside copper plate comprises a broadside copper plate body and a plurality of rows of screw holes arranged on the broadside copper plate body. A cold surface of the broadside copper plate body is provided with a cooling water tank. The crystallizer broadside copper plate is characterized in that the cooling water tank comprises deep water tanks and shallow water tanks which are different in depth; and between two adjacent rows of the screw holes, two deep water tanks are arranged symmetrically and close to the screw holes, and two shallow water tanks are arranged symmetrically and close to center lines of the two rows of the screw holes. The crystallizer broadside copper plate is based on thermophysical parameters of a crystallizer copper plate, proceeds from heat transfer between a high temperature solidification blank shell and the crystallizer copper plate, and enables the crystallizer copper plate to have high cooling intensity and cooling uniformity by means of changing the depth and distribution of the cooling water tank. Therefore, uniformity of the heat transfer is achieved on the basis of ensuring fast heat transfer between the copper plate and a high temperature casting blank, uniform thermal load of the copper plate is guaranteed, and the purposes of improving casting blank quality, prolonging service life of the copper plate and reducing production cost are achieved.
Description
Technical field
The utility model relates to continuous cast mold, refers to a kind of wide copper coin of crystallizer that is used for efficient slab caster particularly.
Background technology
As the heart of continuous casting, the casting process in the crystallizer is that an association heat transfer, solidified, flows and the complex process of phenomenon such as solute reallocation.Interrelated between each phenomenon, the reciprocal effect effect makes the heat transfer behavior in the crystallizer become unusual complicated.Wherein, the diabatic process of molten steel has very significant effects to slab quality in the crystallizer.For adapting to the contraction of high temperature billet shell in crystallizer, improve cooling condition, improve casting speed, improve slab quality, rational sink structure just plays crucial effects in the copper plate of crystallizer.The inhomogeneous strand crackle that is easy to cause that conducts heat also is prone to cause simultaneously the internal stress, face crack of copper coin itself and the appearance of unfavorable phenomenon such as crystallization again.Based on this, the design of copper coin sink structure to the direct motion of whole casting process, optimize slab quality, improve the copper plate of crystallizer life-span and aspect such as reduce production costs all has crucial meaning.
The utility model content
The utility model technical problem to be solved just provides a kind of wide copper coin of crystallizer that is used for efficient slab caster; Can be on the basis that guarantees the copper plate of crystallizer intensity of cooling; Improve its cooling uniformity, for the carrying out of efficient sheet billet continuous casting, improve the copper coin life-span and reduce production costs feasible way is provided.
For solving the problems of the technologies described above; A kind of wide copper coin of crystallizer that is used for efficient slab caster that the utility model provides; Comprise wide copper coin body and on some row screw holes; The huyashi-chuuka (cold chinese-style noodles) of wide copper coin body is provided with bosh, and its special feature is: said bosh comprises bendway and the shallow-water tank that the degree of depth is different; Between adjacent two row screw holes, two bendways are symmetrical set near screw hole, and two shallow-water tanks are symmetrical set near the center line of two row screw holes.
In the technique scheme, the degree of depth of said bendway is 18 ~ 22mm, and the degree of depth of said shallow-water tank is 10 ~ 16 mm.
Further, the distance of the end of said bosh and wide copper coin body top and bottom is respectively 20 ~ 30mm.
Further, the end of said bosh is the rounding that radius is 60 ~ 80 mm.
The heat transfer relation of copper plate of crystallizer and high temperature strand many aspects such as slab quality, copper coin life-span and production cost, has crucial effects, and the bosh structure that be copper plate of crystallizer relevant with the copper coin cooling capacity.Compared with prior art; The utility model is the basis with the thermal physical property parameter of copper plate of crystallizer; From the heat transfer between high temperature solidified shell and copper plate of crystallizer; Designed wide copper coin of a kind of rational crystallizer,, made copper plate of crystallizer have higher intensity of cooling and cooling uniformity through the degree of depth and the distribution that changes its bosh.Thereby on the quick heat exchange basis that guarantees between copper coin and high temperature strand, realized the uniformity of heat exchange, guaranteed that the thermic load of copper coin is even, and then reached the purpose that improves slab quality, improves the copper coin life-span and reduce production costs.
In actual production; The strand of cast 1600mm * 220mm is an example; The crystallizer that utilizes wide copper coin of the utility model to constitute; Realized that 395 ℃ of crystallizer hot-face temperatures (being lower than the recrystallization temperature of copper coin) and hot-face temperature uniformity remain on 10 ℃ with interior effect, the crystallizer (hot-face temperature fluctuates in 30 ~ 50 ℃ of scopes) that more traditional equidistance, wide copper coin of even depth sink structure constitute has had remarkable lifting.

Among the figure: 1-wide copper coin body, 2-screw hole, 3-bendway, 4-shallow-water tank.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further to describe in detail.
Extremely shown in Figure 3 like Fig. 1; A kind of wide copper coin of crystallizer that is used for efficient slab caster of the utility model; Comprise the bosh that is provided with on some row screw holes 2 and wide copper coin body 1 huyashi-chuuka (cold chinese-style noodles) on wide copper coin body 1, wide the copper coin body 1; Fig. 1 has illustrated the structure of 1 one repetition periods of wide copper coin body; Visible by figure, the bosh of present embodiment comprises darker two bendways 3 and two more shallow shallow-water tanks 4, and the degree of depth of bendway 3 and shallow-water tank 4 is respectively 21mm and 16mm.Between adjacent two row screw holes 2, two bendways 3 are symmetrical set near screw hole 2, and 4 center lines near two row screw holes 2 of two shallow-water tanks are symmetrical set.Bendway 3 is provided with near screw hole 2, has increased near the heat-transfer capability the screw hole 2, and 4 of two shallow-water tanks in middle part play the evenly effect of the hot-face temperature of wide copper coin body 1, for the longevityization of wide copper coin has played important function.Bendway 3 is 25mm with shallow-water tank wide copper coin body 1 top of 4 distances and bottom position; Guaranteed up and down property symmetrically; Each bosh end is the rounding that radius is 60mm, has greatly strengthened the heat-transfer capability at meniscus position place, also constitutes the assurance that the continuous casting high efficiency is produced.
