In the liquid steel level position, owing to reasons such as liquid fluctuatings, make copper plate of crystallizer bear thermic load much larger than other position from molten steel in this position, therefore the fire check at this position copper coin is the main reason that copper plate of crystallizer lost efficacy, especially middle high draw speed plate blank continuous casting, optimize the crystallizer copper plate structure at liquid steel level place, become the strategic point of continuous casting line continous-stable operation.
Summary of the invention
The purpose of this utility model is to provide a kind of change tank cross sectional plates billet crystallizer copper coin, by changing the cross sectional shape of molten steel surface location high-temperature region copper plate of crystallizer bosh, accelerate the flow velocity method of cooling water in the tank of copper coin high heat load zone, the heat transfer of reach the maximum temperature that reduces copper coin, quickening copper plate of crystallizer high heat load district lead, make the copper plate working surface Temperature Distribution more evenly, prolong copper plate of crystallizer purpose in service life.
Technical scheme of the present invention is: a kind of change tank cross sectional plates billet crystallizer copper coin, mainly comprise: a copper plate of crystallizer inner panel, the tank that has some parallel and variable cross-sections on its inner panel, a water tank that links to each other with inner panel by threaded connector, at water tank and copper plate of crystallizer inner panel adjacent surface, be distributed with the rib that is cemented in the some parallel and variable cross-section on the water tank with variable cross-section tank correspondence position.
Aforesaid change tank cross sectional plates billet crystallizer copper coin, it is characterized in that: inner panel tank changes of section section and rib distributing position are positioned at the high heat load district of crystallizer top near the liquid steel level high-temperature region, can take away more heat by cooling water.
Aforesaid change tank cross sectional plates billet crystallizer copper coin, it is characterized in that: becoming tank cross section section, the common concave cross section tank that forms a sealing of crystallizer inner panel, water tank and rib, its sectional area reaches this concave cross section section cooling water flow velocity and is higher than other section effect less than the sectional area of crystallizer bottom rectangle tank.
Aforesaid change tank cross sectional plates billet crystallizer copper coin, it is characterized in that: two of the variable cross-section tank sides are trapezoidal on the crystallizer inner panel, make the cross section expand gradually and shrink, help destroying the laminar film between the cooling liquid and cooling bath wall in this zone.
Aforesaid change tank cross sectional plates billet crystallizer copper coin, it is characterized in that: rib is similar to variable cross-section section shape on the crystallizer inner panel, be long hexagonal prism type, along increasing gradually perpendicular to the length direction cross section, keep subsequently, shrink gradually at last, form the concave cross section tank of this section sealing.
Aforesaid change tank cross sectional plates billet crystallizer copper coin is characterized in that: rib is connected with water tank by securing member or processes with the water tank one, is convenient to dismounting and maintenance.
Beneficial effect of the present invention is: for general plate slab crystallizer copper coin, because the cross sectional shape of tank is constant, to the bottom, the coefficient of heat transfer between crystallizer tank and the cooling water is constant substantially from the crystallizer top.The utility model copper plate of crystallizer is by changing the cross sectional shape method of molten steel near surface inner panel tank, improved the flow velocity of this place's cooling liquid, increase is to the cooling of this position copper plate of crystallizer, improve between water channel bottom and adjacent water channel crystallizer internal cavity heat and conducted non-uniform phenomenon in the horizontal direction, reduce the maximum temperature of copper coin hot side, the meniscus surface area that is reduced in copper coin cracks and makes the tendency of plating exfoliation, the change of cross sectional shape simultaneously destroyed should the zone in laminar film between cooling liquid and the cooling bath wall, more effectively improve the heat transfer efficiency in copper plate of crystallizer high heat load district, reduce the maximum temperature of copper coin, it is more even that copper plate temperature is distributed, and prolonged the service life of copper plate of crystallizer.
