Abstract
A crystallizer used for enabling the steel liquid to solidifying into a blank shell in a caster is provided. The internal wall of the crystallizer is divided into two sections; an upper section is a copper layer which is integrated into a whole with an external wall 1; a lower section is a cermet layer; the internal surface of the upper section and the lower section is a contour surface. The length of the lower section cermet layer is 1/20 to 1/2 of the whole length of the crystallizer. The thickness of the cermet layer is between 0.5 and 4.0 mm. The crystallizer is taken as a whole, the internal wall is divided into different upper and lower sections; the upper part still keeps good heat dissipation performance; the lower part has not only better heat dissipation performance but also anti-wear performance. As the cermet has the two characteristics, thus, not only the surface quality of the casting billet is improved, but also the service life of the crystallizer is improved and the steel leakage ratio in the operation is reduced.
Description
One, technical field:
The utility model is used in to smelt in the conticaster and makes solidification of molten steel become the parts of base shell.
Two, background technology
Employed crystallizer on the conticaster of smelting industry is to make the molten steel cooled and solidified become the parts of hard base shell at present, and it is divided into tubular type or combined type, is made by copper product.When molten steel injects crystallizer, top is that the soft high temperature billet shell of one deck bag is being praised the molten steel that stirs up and down, the crystallizer of this moment is based on heat radiation, and is not easy to wear, during to the middle and lower part, thick and the hardening of gradual change of base shell, the thermolysis of crystallizer is less than half of bent face, and it mainly acts on and has become holder and is holding up the base shell to move down, thereby the friction of crystallizer copper pipe (plate) inwall is increased, and present crystallizer is to make of copper product, because of its underpart wearing and tearing are scrapped.Its life-span is short, and the breakout ratio height brings inconvenience to production.
Three, summary of the invention
The utility model is for designing a kind of existing good thermal diffusivity the crystallizer of wearability to be arranged again.
The inwall of tubular crystallizer is two sections, and epimere is and the copper layer of outer wall one that hypomere is a cermet coating.Last hypomere inner surface is a contour plane, and the length of hypomere cermet coating is 1/20th to 1/2nd of solid block mold length.The thickness of cermet coating is 0.5---between 4.0mm.The structure of fourplatemold and tubular crystallizer are basic identical, and the inwall hypomere that also is every block of plate is a cermet coating.
This crystallizer is done as a whole, and its inwall is divided into different two sections, and top still maintains good thermal diffusivity, and the existing thermal diffusivity preferably in bottom has wearability again.Because cermet has this two aspect characteristic.Thereby not only improved cc billet surface quality but also improved the service life of crystallizer, reduced operating breakout ratio.
Four, description of drawings
Accompanying drawing is the cross-sectional view of the whole two-stage crystallizer of tubular type.
Ground, the specific embodiment
Example 1, be example: processing is carried out in former crystallizer (1) inwall bottom with the tube type mold, as machining, remove thickness as 2mm, then the bottom is sprayed, cermet coating (2) is closely attached to the surface of processing, up to its surface with upper face is contour will be by desirable radian correction of the flank shape.
Example 2, be combined type as crystallizer (1), just every newspaper inner surface lower part processed spray coating metal ceramic layer (2), top and the bottom are contour plane.
Claims (3)
1, make solidification of molten steel become the crystallizer of base shell in a kind of conticaster, it is characterized in that: the inwall of crystallizer is two sections, and epimere is and the copper layer of outer wall 1 one, and hypomere is cermet coating (2), and last hypomere inner surface is a contour plane.
2, crystallizer according to claim 1 is characterized in that: the length of hypomere cermet coating (2) is 1/20th to 1/2nd of solid block mold length.
3, crystallizer according to claim 1 is characterized in that: the thickness of cermet coating is between 0.5--4.0mm.
