Abstract
The utility model relates to a meniscus narrow and shallow flume hot top crystallizer molding board for the technical field of molding, which is mainly characterized in that the profile of the cooling flume of the hot top crystallizer molding board is a combined structure, which has narrow and shallow top and wide and deep bottom; the narrow and shallow flume is arranged at the meniscus and a cooling water distributing channel is formed on the contacting surface between the two flumes; small amount of water passes through the meniscus and carries away small heat; large amount of water passes through the area under the meniscus and carries away large heat; the working surface of the meniscus is provided with thick low thermal conduction abrasion proof metal coating layer for increasing the heat resistance, so as to reduce the heat flux density at meniscus and make a nascent case grow evenly and reduce the sensitivity of the crack. The utility model has the advantages of improving the quality of continuous casting, improving the work efficiency and prolonging the period of usage of the hot top crystallizer.
Description
Technical field
The utility model belongs to casting technology field, is specifically related to the hot top of narrow shallow-water tank, a kind of meniscus district crystallizer stencil.
Background technology
In known technology, the tank in crystallizer stencil meniscus district, hot top is identical with the tank of template bottom.Tank bottom surface, meniscus district is identical to the thickness of working face with tank bottom surface, bottom, and the flow velocity of cooling water is identical, and the heat that cooling water is taken away is identical.Because the temperature of (meniscus district) molten steel is high relatively in the porch, it is inhomogeneous soon to cause the meniscus district to be conducted heat, and makes initial solidification shell growth crystal grain inhomogeneous, and oscillation mark is dark, and crack sensitivity is strong.In the use, continuous casting billet, especially the mild steel continuous casting billet easily cracks, and reduces the quality of continuous casting billet.
Summary of the invention
The purpose of this utility model is to design a kind of meniscus district and conducts heat evenly gently, and the hot top crystallizer stencil of initial solidification shell uniform crystal particles is used to improve the quality of continuous casting billet.
For reaching above-mentioned purpose, the main technical schemes that the utility model adopted is: combination shape tank is set on crystallizer stencil, narrow shallow-water tank promptly is set on the template body in meniscus district, shallow dark arcwall face is down presented in this tank bottom surface, narrow shallow-water tank is connected with former tank on the meniscus district bottom template, basifacial forms split channel under two tanks join, and it is up-narrow and down-wide that tank is, last shallow dark combination shape tank down.And thick low heat conduction antifriction metal (AFM) coating is set on the working face in meniscus district.
The hot top of narrow shallow-water tank, the meniscus district crystallizer stencil of making according to such scheme can be at continuous casting billet, especially in the mild steel continuous casting billet, has solved the meniscus district fast uneven problem of conducting heat effectively.Because what the meniscus district was provided with is narrow shallow-water tank, bottom, meniscus district is provided with wide bendway, and the cooling-water duct of shunting is arranged, and the meniscus district water yield is few, and the heat that the meniscus district is taken away is few, and the following water yield in meniscus district is big, and it is many to take away heat.And the meniscus area working face is provided with thick low heat-conducting metal or alloy (as: nickel plating, nickel cobalt (alloy) etc.), increases thermal resistance, and meniscus district heat flow density is reduced, form hot top crystallizer, the initial solidification shell growth is even, and crack sensitivity reduces, and continuous casting billet quality can be greatly improved.Have the quality that can improve continuous casting billet, enhance productivity, prolong the advantages such as service life of hot top crystallizer stencil.
Reach example in conjunction with the accompanying drawings and further specify specific structural features of the present utility model.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is an A-A cutaway view of the present utility model.
The specific embodiment
Referring to Fig. 1, Fig. 2 the utlity model has template body 1, tank.Tank is by narrow shallow-water tank 2, and tank 3 is formed.Be provided with narrow shallow-water tank 2 in the meniscus district of template body 1, shallow dark arcwall face 6 is down presented in the bottom surface of narrow shallow-water tank 2, tank 3 is arranged on the bottom, meniscus district of template body 1, the former tank that tank 3 adopts on the template, narrow shallow-water tank 2 is connected with tank 3, form split channel 4 in two tank abutted surface bottoms, corresponding water tank is provided with shunting cooling-water duct (double dot dash line signal) tank and is up-narrow and down-wide, last shallow dark combination shape tank down.The working face in template body 1 meniscus district is provided with thick nickel-cobalt alloy plating 5.
