Description

[0002] Aluminium alloy ingot needs to be treated by extrusion deformation, solid solution and aging process in industrial production to obtain finished product with excellent performance, but actual production conditions result in a large number of non-equilibrium precipitated phases in the ingot which are not conducive to subsequent processing. These non-equilibrium precipitated phases are mainly coarse Mg2Si primary phase and AlFeSi impurity phase, and the undissolved Mg2Si primary phase will lead to the decline of aging strengthening effect of the material, and the AlFeSi impurity phase will lead to uneven deformation or even failure of the material in the pressure processing, so the ingot needs to be homogenized before pressure processing. Homogenization treatment can dissolve Mg2Si primary phase in the aluminium alloy ingot and convert coarse rod-shaped AlFeSi phase into granular shape, thereby reducing the organizational heterogeneity and internal stress of the ingot and facilitating subsequent pressure processing.

[0014] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described in combination with specific embodiments.

[0015] The first embodiment of the utility model provides a homogeneous cooling auxiliary device, referring to Figures 1-2 The cooling furnace body is distributed on, for example, a concrete foundation, and has a left furnace wall 1a, a right furnace wall 1b and a furnace body top 1c. A furnace door and a back furnace wall are respectively arranged at the front end and the rear end of the cooling furnace body. The material of the cooling furnace body can be metal material, but is not limited to metal material. A base 2 is arranged in the cooling furnace body along the length direction of the cooling furnace body, Figure 2 The left-right direction is the length direction of the cooling furnace body, and Figure 1The left and right directions shown are the width direction of the cooling furnace body. The base is provided with a plurality of layers of casting rod bearing pad groups 3 distributed along the width direction of the cooling furnace body, for example, five layers of casting rod bearing pad groups, each layer of casting rod bearing pad group having seven long strip-shaped pads 4 distributed at equal intervals, the length of the long strip-shaped pad being less than the width of the inner chamber of the cooling furnace body, leaving a corresponding space in the inner chamber of the furnace body, which can increase the safety of work and facilitate the corresponding maintenance work. The gap of each layer of casting rod bearing pad group is provided with a cooling water spray pipe 5 extending into the cooling furnace body from the side wall of the cooling furnace body, through which the casting rod can be quickly sprayed and cooled. The top of the cooling furnace body is provided with a cooling water spray pipe 5 for cooling the uppermost layer of casting rod. The cooling water dropped from the upper cooling water spray pipe flows naturally to the bottom of the cooling furnace body. The two side walls of the cooling furnace body in the width direction are provided with insertion holes corresponding to the distribution position of the cooling water spray pipe. The number of insertion holes corresponds to the number of cooling water spray pipes. The hole wall of the insertion hole can be sleeved with a rubber sleeve or a ceramic sleeve.

[0016] Referring to Figure 2 As shown, the cross section of the long strip-shaped pad is rectangular. Regular rectangle can avoid displacement (rolling) of the pad. The width of the long strip-shaped pad is greater than the height of the long strip-shaped pad. The wider pad can increase the contact surface with the casting rod to improve the stability of the casting rod. The height of the pad is lower than the width, which can maximize the overall height of the multi-layer pad group and increase the space utilization efficiency of the inner chamber of the furnace. As an option, the long strip-shaped pads of the cooling furnace body are distributed in a rectangular array in the furnace chamber of the cooling furnace body, for example Figure 2 As shown, five rows and seven columns, a total of 35 long strip-shaped pads are distributed in the furnace chamber.

[0017] Here, the five layers of cooling water spray pipes are defined from bottom to top as the first layer of spray pipe K1, the second layer of spray pipe K2, the third layer of spray pipe K3, the fourth layer of spray pipe K4, and the fifth layer of spray pipe K5.

[0018] It is worth mentioning that the cooling water spray pipe of the present case does not adopt a single straight-through furnace chamber scheme, but adopts a segmented distribution scheme. Specifically, referring to Figure 1 Among the interlayer-distributed cooling water spray pipes, the cooling water spray pipes on the same axis (for example, the axis I of the bottom-distributed cooling water spray pipe) adopt an opposite distribution. One cooling water spray pipe on the left side extends into the furnace chamber vertical center axis O from the left side wall of the cooling furnace body, and one cooling water spray pipe on the right side extends into the furnace chamber vertical center axis O from the right side wall of the cooling furnace body. This segmented distribution scheme can increase the spraying efficiency and avoid the problem of low insertion efficiency caused by inserting a single water spray pipe. A plurality of spray holes are formed in the wall of each cooling water spray pipe. Each cooling water spray pipe is connected to a water source, for example, a water pump is used to send water to each cooling water spray pipe. The cooling water spray pipe can be a circular pipe, of course, it can also be a square flat tube.

[0019] The cushion blocks here can be in a detachable mounting form, and after the casting bars are placed in layers, a layer of long strip-shaped cushion blocks is placed, and the placing work of the casting bars in the furnace stone is completed in sequence, and then the cooling water spraying pipes are inserted to start the spraying operation.

[0020] The water supply system connected to the cooling water pipe is omitted in the embodiment.

[0021] The second embodiment of the utility model provides a homogenizing cooling auxiliary device, which is different from the first embodiment in that the side wall of the cooling furnace body is provided with a guide sleeve 7 matched with the cooling water spraying pipe.

[0022] Referring to Figure 3 The guide sleeve 7 has a ceramic cylinder body 7a mounted on the side wall of the cooling furnace body and a rubber cylinder body 7b mounted on the ceramic cylinder body, and the end of the rubber cylinder body is provided with an embedded part in L-shaped section, which is embedded into the ceramic cylinder body. The guide sleeve adopts a ceramic sleeve combined with a rubber sleeve at the tail end, which can improve the insertion operation of the cooling spraying pipe, effectively avoid the impurities of the furnace wall from blocking the spraying holes of the cooling spraying pipe, and the rubber sleeve can have a large friction force between the cooling spraying pipes, thereby improving the installation stability of the cooling spraying pipe.

[0023] The cross-sectional shape of the guide sleeve here is determined according to the cross section of the cooling spraying pipe. When the cross section of the cooling spraying pipe is circular, the guide sleeve adopts a circular cross section. Similarly, when the cross section of the cooling spraying pipe is square, the cross section of the guide sleeve is also square, and other cross-sectional shapes are similarly used.

[0024] As another embodiment, a middle guide pipe can be mounted in the inner hole of the cooling spraying pipe, which can form an annular water channel with the cooling spraying pipe. The annular water channel directly diffuses the cooling water outward from the holes on the surface of the cooling spraying pipe under the action of pressure. In the case of a relatively thick pipe diameter, if the internal cooling water is too heavy, it will easily affect the carrying capacity of the cooling spraying pipe. The middle guide pipe can be made of plastic material, which can reduce the water carrying capacity inside the cooling spraying pipe by reducing the cross section.

[0025] Those skilled in the art can understand that the above embodiments are specific embodiments for implementing the utility model, and in actual application, various changes can be made in form and details without departing from the spirit and scope of the utility model.
