Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative effort belong to the protection scope of the present invention.

In the following description, the appearances of the indicating orientation or positional relationship such as the terms "inner", "outer", "upper", "lower", "left", "right", etc. are only for convenience in describing the embodiments and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the present invention.

Example (b):

referring to fig. 1-2, the present embodiment provides a continuous casting mold, which includes a copper substrate 1, a cooling pipe 4, a shunt pipe 5, a collecting pipe 6, a water inlet pipe 2, and a water outlet pipe 3.

In this example, the cooling target of the continuous casting mold is a rectangular parallelepiped graphite mold, two continuous casting molds are used in a set, and the two continuous casting molds are respectively installed on the upper bottom surface and the lower bottom surface of the rectangular parallelepiped graphite mold.

The copper substrate 1 is a rectangular plate so as to be attached to the bottom surface of the rectangular graphite mold, and the heat of the graphite mold is transferred to the copper substrate 1 as much as possible.

Taking the continuous casting crystallizer installed on the upper bottom surface of the graphite mold as an example, the water inlet pipe 2 and the water outlet pipe 3 are both located above the copper substrate 1, so as to avoid interfering with the bonding state of the graphite mold and the copper substrate 1. In view of the conventional structural arrangement of the piping, the water inlet pipe 2 and the water outlet pipe 3 are both arranged perpendicular to the copper substrate 1.

The number of the cooling pipes 4 is multiple, all the cooling pipes 4 are laid in the copper substrate 1 side by side, and two ends of each cooling pipe 4 are respectively communicated with the water inlet pipe 2 and the water outlet pipe 3. The water inlet pipe 2 conveys cooling water to the cooling pipe 4, the cooling water enters the copper substrate 1, and the cooling water flows to the water outlet pipe 3 through the cooling pipe 4 and is discharged from the inside of the copper substrate 1. The heat of the graphite mold is transferred to the copper substrate 1 and then taken away by the cooling water. Therefore, the greater the number of cooling pipes 4, the greater the cooling capacity of the copper substrate 1.

The shunt tubes 5 and the collecting tubes 6 are inserted in the copper base plate 1, and two ends of the shunt tubes 5 and two ends of the collecting tubes 6 are sealed. Trompil has been seted up to shunt tubes 5's the lateral wall and the lateral wall of collecting pipe 6, and the both ends of cooling tube 4 are pegged graft respectively in the trompil of shunt tubes 5 and the trompil department of collecting pipe 6 to make the one end of cooling tube 4 communicate to shunt tubes 5, the other end of cooling tube 4 communicates to collecting pipe 6. The water inlet pipe 2 is communicated with the shunt pipe 5 and further communicated with the cooling pipe 4. The water outlet pipe 3 is communicated to a collecting pipe 6 and further communicated with the cooling pipe 4. The inlet tube 2 disperses the cooling water to each cooling tube 4 through the shunt tubes 5, and the cooling water in each cooling tube 4 takes away the heat and gathers to the collecting pipe 6, and then discharges in unison through the outlet pipe 3. The shunt tubes 5 and the collector tubes 6 simplify the piping outside the copper base plate 1.

Structural design that cooling tube 4 laid side by side for different cooling tube 4 projections on copper base plate 1 bottom surface can not coincide, and the projection of all cooling tube 4 on copper base plate 1 bottom surface also covers whole copper base plate 1 bottom surface as far as simultaneously, and the heat can directly be taken away from each part on copper base plate 1 to the cooling water, and each part of corresponding copper base plate 1 also can effectively absorb the heat from the graphite jig, makes copper base plate 1 obtain optimizing to the cooling capacity of graphite jig. In addition, different cooling tubes 4 do not absorb heat to the same portion of the copper substrate 1, and each cooling tube 4 can be fully utilized.

In order to promote the length of cooling tube 4 to increase the cooling capacity of cooling tube 4, shunt tubes 5 and collector 6 are on a parallel with the preceding side of copper base plate 1, and shunt tubes 5 are located the edge of the preceding side of copper base plate 1, and collector 6 is located the edge of copper base plate 1 back side, and corresponding cooling tube 4 is located between shunt tubes 5 and the collector 6, and the length of cooling tube 4 can be as far as possible with the width maintenance unanimity of copper base plate 1.

The corresponding water inlet pipe 2 is vertical to the shunt pipe 5, and the water outlet pipe 3 is vertical to the collecting pipe 6.

In order to effectively absorb heat to the whole graphite mold, the length of the cooling pipe 4 is preferably greater than 1m, so that the length of the cooling pipe 4 is greater than the width of the graphite mold.

The cooling pipes 4 are round pipes, all the cooling pipes 4 are parallel to each other, and the diameter of any cooling pipe 4 is a fixed value R. The maximum cooling capacity of the individual cooling tubes 4 is therefore approximately fixed.

The axial distance between the adjacent cooling pipes 4 is L, so that in order to avoid heat absorption blind areas generated between the adjacent cooling pipes 4, L is less than or equal to 1.5R.

Preferably, L is 1.5R, and in this case, the heat absorption capacity of each portion of the copper substrate 1 is substantially the same.

In this embodiment, the length of the shunt tube 5 in the copper substrate 1 and the length of the manifold 6 in the copper substrate 1 are both greater than 2m, and the distance between the two cooling tubes 4 at the farthest distance can reach 2m as much as possible, so that the cooling tubes 4 can be projected on the graphite mold as much as possible along the normal direction of the copper substrate 1, and the cooling capacity of the continuous casting mold of this embodiment on the graphite mold is increased.

Due to the improvement of the continuous casting crystallizer, the drawing speed of the lead brass continuous casting rod in the graphite mold is also improved, and the specific numerical values are shown in the table 1.
