Technical field
The present invention relates to a kind of crystallization apparatus, especially a kind of crystallizer that can reduce the service life of the dummy ingot resistance of crystallizer lower surface, the quality that improves ingot casting center line and strand, prolongation crystallizer.
Background technology
Usually, the crystallizer that horizontal casting production bronze uses all is that the Inlet and outlet water quantity of upper and lower surface is the same, all adopts two to advance three and go out or two advance four and go out, and the number of upper and lower surface import and export is symmetrical.But, the difference of ingot casting upper and lower surface cooling degree is not considered in traditional crystallizer design, after discarded crystallizer dismounting, can find, the degree of wear of the graphite cake of each crystallizer upper and lower surface is different, upper surface only exists slight wearing and tearing and the adhesive of a little, but not only there is serious wear phenomenon on the surface of the graphite cake of lower surface, and is that have even broken.
Because the pressure of copper liquid makes the scull of ingot casting be close to crystallizer wall, because the crystallizer residing liquid-column height difference in position up and down, scull suffered pressure ratio top in bottom is big in the crystallizer.In addition, because under the effect of ingot casting self gravitation, up and down the tightening degree bottom is greater than top at crystallizer to cause scull, thereby the contact length bottom of scull and crystallizer has caused dummy ingot resistance bottom greater than top greater than top.
In addition, the temperature of crystallizer top melt is than the bottom height during horizontal casting, thereby the crystallization of crystallizer top ingot casting is more late than the bottom, observes and measures and find by the low power sample of ingot casting, exist nucleus of crystal phenomenon on the upper side during the horizontal casting ingot casting, caused the inhomogeneous of ingot structure like this.When poring rate was accelerated, the nucleus of crystal eccentricity value can diminish, but ingot casting speed is too fast, can increase the internal flaw of strand, even caused the bleedout copper strips.At present, good solution is not also arranged.
Summary of the invention
Technical assignment of the present invention is to provide a kind of crystallizer at above-mentioned deficiency of the prior art, this a kind of crystallizer has the temperature that has reduced the ingot casting upper surface, make ingot casting upper and lower surface even tissue, increased the intensity of cooling of graphite cake above the crystallizer, reduced the intensity of cooling of crystallizer lower surface, make ingot casting crystallization simultaneously up and down in the crystallizer, the degree of wear of crystallizer lower surface graphite cake has some improvement, and has increased the characteristics in service life.
The technical solution adopted for the present invention to solve the technical problems is: it comprises the crystallizer housing, the top of described crystallizer housing is provided with top delivery port and top water inlet, the crystallizer lower part of frame is provided with bottom delivery port and lower water inlet, described top water inlet and lower water inlet are respectively two, described top water inlet and lower water inlet are symmetrical arranged, the quantity of described top delivery port is more than the quantity of bottom delivery port, the setting that is staggered of described bottom delivery port and lower water inlet.
