The continuous casting rod close to one side of the water cooling jacket and far away from one side of the water cooling jacket in the mold is easy to have uneven temperature (the appearance shows uneven red heat degree) due to large difference of cooling amount. Secondly, when the graphite mold is used for producing continuous casting rods, the cooling capacity of copper rods is small, the traction speed is limited, and the production efficiency is low.
[ summary of the invention ]

The technical scheme adopted by the invention is as follows:
a graphite mould comprises a cuboid mould body, a plurality of continuous casting channels are communicated between the front side surface and the rear side surface of the mould body, the side wall of each continuous casting channel is in a round table shape, the axis of each continuous casting channel is perpendicular to the front side surface and the rear side surface of the mould body, an opening of each continuous casting channel, which is located on the front side surface of the mould body, is a copper inlet, and the diameter of each copper inlet is D1The opening of the continuous casting channel on the rear side surface of the die body is a copper outlet with the diameter D2，200mm≥D2≥10mm，D1＞D2。
The invention has the beneficial effects that:
the rectangular parallelepiped mold body allows each continuous casting channel to be formedThe graphite mold is close to the water cooling jacket as much as possible, so that the temperature in each continuous casting channel can be as consistent as possible, and the temperature of the whole graphite mold is more uniform. D can be adjusted according to the specification of the finished product of the continuous casting rod and the wire drawing allowance1D of different continuous casting passes1May be of different values to produce a plurality of specifications of continuous cast rods. D2Limiting the volume shrinkage of the lead brass between the liquid and solid states.
The axes of all the continuous casting channels are in the same plane, and the planes of the axes of all the continuous casting channels are parallel to the upper side surface and the lower side surface of the die body.
The planes of all the continuous casting channel axes are the symmetrical planes of the upper side surface and the lower side surface of the die body.

[ detailed description ] embodiments
The technical solutions of the embodiments of the present invention are explained and illustrated below with reference to the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, and not all embodiments. 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 graphite mold for producing a lead brass continuous casting rod, which includes a rectangular parallelepiped mold body 1, and a plurality of continuous casting channels 2 communicated between a front side surface and a rear side surface of the mold body 1.
The continuous casting channels 2 are used for producing continuous casting rods, and the number of the continuous casting rods which can be produced by the graphite molds at the same time is the number N of the continuous casting channels 2. Under the condition that the volume of the die body 1 is certain, N is too large, so that the continuous casting channels 2 are too dense, the adjacent continuous casting channels 2 are mutually influenced in the cooling process, and N is too small, so that the production efficiency of the graphite die is too low. According to actual production conditions, generally 20N 3.
The side wall of the continuous casting channel 2 is in the shape of a circular table, and the axis of the continuous casting channel 2 is vertical to the front side surface and the rear side surface of the die body 1. Wherein the opening of the continuous casting channel 2 positioned on the front side surface of the die body 1 is a copper inlet 3, and the diameter of the copper inlet 3 is D1The opening of the continuous casting channel 2 on the rear side surface of the die body 1 is a copper outlet 4, and the diameter of the copper outlet 4 is D2，D1＞D2。
D1The specific numerical value of the continuous casting rod is determined according to the specification of the finished product of the continuous casting rod and the wire drawing allowance. D of different continuous casting channels 21The values are different, so that the graphite mold of the embodiment can produce continuous casting rods with a plurality of specifications.
200mm≥D2Not less than 10mm to limit the volume shrinkage rate between liquid state and solid state of the lead brass.
In order to make the volume shrinkage of each part as uniform as possible during the production of the continuously cast rod, 2D is preferred2≥D1。
Furthermore, the volume shrinkage of the lead brass between the liquid and solid state is also dependent on the distance L between the front and rear sides of the mould body 1, L being the length of the continuous casting channel 2, preferably L ≧ 10 (D)1-D2)。
For effective use of the mould body 1, the axes of all the continuous casting channels 2 are in the same plane, and the planes of the axes of all the continuous casting channels 2 are parallel to the upper side and the lower side of the mould body 1.
Furthermore, the planes of the axes of all the continuous casting channels 2 are the symmetrical planes of the upper side surface and the lower side surface of the die body 1.
The cuboid mould body 1 makes each continuous casting channel 2 as close as possible to the water cooling jacket. The larger the volume of the continuous casting channel 2, the closer the continuous casting channel 2 is to the water cooling jacket, the larger the cooling amount is, so that the temperature in each continuous casting channel 2 is approximately the same, and the temperature of the whole die body 1 is more uniform.
In addition, water cooling sleeves can be respectively arranged on the upper side surface and the lower side surface of the die body 1, so that the temperature in the single continuous casting channel 2 can be as uniform as possible, and the occurrence of cracking of the continuous casting rod caused by nonuniform temperature is reduced.
The traction speed of the graphite mold of the embodiment is greatly improved compared with that of the existing four-hole graphite sleeve, and the drawing speed is specifically shown in table 1.
