Abstract

The invention discloses a funnel-shaped crystallizer copper plate mould of a continuous casting sheet billet. The funnel-shaped crystallizer copper plate mould comprises a cooling water tank, a cooling water tank surface, inlaid strips, a rib plate and a water through hole in the rib plate, wherein the front side of the cooling water tank is a funnel-shaped working face, and the back surface of the cooling water tank has a cooling function; the inlaid strips are inserted into the cooling water tank to control the section dimension of the cooling water tank; the rib plate is arranged between the cooling water tank; the inlaid strips are connected with two positioning mechanisms arranged on the upper part and the lower part of the cooling water tank surface; the inlaid strips and the cooling water tank form a water passing sectional area and are fixed through the positioning mechanisms; the cooling water tank sectional area of the high-temperature area of the copper plate mould is smaller than the area of the middle lower part; a distance between the working face of the high-temperature area of the copper plate mould and the bottom surface of the cooling water tank of the copper plate is smaller than the distance of the middle lower part; a distance between the center of the water hole of the high-temperature area of the copper plate mould and the working face of the copper plate mould is smaller than the distance of the middle lower part; therefore, the defect that water flow on a regulation screw position disorders since the area of the water tank is occupied because the regulation screw is adopted to regulate the inlaid strips is overcome, the service life of the copper plate mould is prolonged, and meanwhile, the quality of a continuous casting billet is stably improved.

Example Embodiment

[0019] Example one: such as figure 1 , figure 2 , Image 6 As shown, a continuous casting thin slab funnel mold copper plate mold includes a funnel-shaped working surface 1 on the front, a cooling water tank 2 with cooling function and a cooling water tank surface 3 on the back, and an inserted cooling water tank 2 to control the cooling water tank 2 The cross-sectional size of the insert 4 also includes the ribs 5 between the cooling water tanks 2 and the water holes 6 on the ribs 5. The copper plate mold is called the upper part near the mouth of the funnel, and the opposite is called the lower part. The strip 4 is connected with two positioning mechanisms arranged on the upper and lower parts of the cooling water tank surface 3, and the cross-sectional area formed by the insert 4 and the cooling water tank 2 is fixed by the positioning mechanism.
[0020] The positioning mechanism is composed of a long keyway 71, a long key 81, and a slot 9 at the connection part of the insert 4 and the long key 81. The long keyway 71 and the long key 81 span all the cooling water grooves 2 of the copper plate mold. , But do not extend the cooling water tank surface 3 of the copper plate mold. The several inserts 4 are connected with the two long keys 81 on the upper and lower parts by fasteners, and are inserted into the corresponding grooves. The long keys 81 and the long keyways 71 are fastened Pieces to connect.
[0021] The cross-sectional depth dimension design of each part of each insert is the same as the corresponding depth dimension of the corresponding cooling water tank. With the weakening of the thermal zone of the copper plate mold, optimally, starting from the upper mouth of the copper plate mold until the distance 150mm, the cross-sectional depth dimension design of each part of each insert and the corresponding depth dimension of the corresponding cooling water tank gradually increase by 20%, from 150mm from the upper mouth to the lower mouth of the copper plate mold. The difference between the section depth dimension of the part and the corresponding part depth dimension of the corresponding cooling water tank remains unchanged.

Example Embodiment

[0022] The second embodiment: the difference from the first embodiment is that: optimally, starting from the upper mouth of the copper plate mold, until the distance from the upper mouth is 250mm, the cross-sectional depth dimension design of each part of each insert and the corresponding depth of the corresponding cooling water tank The size difference gradually increases by 15%, from 250mm from the upper mouth to the lower mouth of the copper plate mold, the difference between the cross-sectional depth dimension of each part of each insert and the corresponding depth dimension of the corresponding cooling water tank remains unchanged.

Example Embodiment

[0023] The third embodiment: the difference from the first embodiment is that: preferably, starting from the upper mouth of the copper plate mold, until the distance from the upper mouth is 300mm, the cross-sectional depth dimension design of each part of each insert and the corresponding part depth of the corresponding cooling water tank The size difference gradually increases by 10%, from the distance of 300mm from the upper mouth to the lower mouth of the copper plate mold, the difference between the cross-sectional depth dimension of each part of each insert and the corresponding depth dimension of the corresponding cooling water tank remains unchanged.
