It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the concept of these exemplary embodiments to those of ordinary skill in the art.

[0052] like Figures 1 to 3 As shown, the embodiment of the present application proposes an externally heated vacuum rolling mill, comprising: a preparation chamber 110, a rolling mill chamber 120 and a cooling discharge chamber 130 which are connected in sequence; wherein the rolling mill chamber 120 comprises: a rolling mill chamber body 121, a heater 122, a rolling mill roller 123 and heating elements 129 to 124, the heater 122 and the rolling mill roller 123 are arranged in the rolling mill chamber body 121, the rolling mill roller 123 is arranged on the side of the heater 122 away from the preparation chamber 110, the heating element 129 is sleeved on the rolling mill roller 123, and in the length direction of the rolling mill roller 123, the heating element 129 is arranged in the middle of the rolling mill roller 123.

[0053] The externally heated vacuum rolling mill provided in the embodiment of the present application includes a preparation chamber 110, a rolling mill chamber 120 and a cooling discharge chamber 130 which are connected in sequence, and the rolling mill chamber 120 includes: a rolling mill chamber body 121, a heater 122, a rolling mill roller 123 and a heating element 129. Based on this, when the magnetic material is rolled, the magnetic powder is pre-treated to form a block material, and then the block material is transported to the preparation chamber 110, and isolated from the external environment by the preparation chamber 110. After that, the entire externally heated vacuum rolling mill system is vented and vacuumed, so that the part to be rolled is The pieces are in a low-oxygen or oxygen-free state, and then the block materials enter the rolling mill chamber body 121 of the rolling mill chamber 120 through the preparation chamber 110. The materials to be rolled pass through the heater 122, and the heater 122 heats the materials to be rolled. Then, the materials are transported to the rolling mill rollers 123, and the rolling mill rollers 123 extrude and roll the materials to be rolled to make the materials more compact and improve the product quality. Finally, the products output by the rolling mill rollers 123 can be shaped by the orthopedic component 124 to obtain the final product, and the final product is output through the cooling discharge chamber 130.

[0054] The externally heated vacuum rolling mill provided in the embodiment of the present application, the rolling mill chamber 120 also includes a heating element 129 mounted on the rolling mill roller 123. Based on this, during the rolling process, the heating element 129 can preheat the rolling mill roller 123 so that the temperature of the rolling mill roller 123 is close to the rolling temperature. Based on this, the heated workpiece to be rolled can be avoided from contacting the roller surface with a lower temperature, and instead can contact the rolling mill roller 123 with a higher temperature, thereby improving the rolling efficiency.

[0055] The externally heated vacuum rolling mill provided in the embodiment of the present application provides heat energy to the rolling mill roller 123 by means of a heating element 129 which is sleeved on the outside of the rolling mill roller 123. The rolling mill roller 123 can be heated without changing the structure of the rolling mill roller 123, thereby facilitating the preparation of the externally heated vacuum rolling mill and reducing costs.

[0056] It can be understood that during the operation of the externally heated vacuum rolling mill, the preheating temperature of the magnetic material is 400-900°C; and the heating temperature of the rolling mill roller 123 is 350-900°C. Based on this, the rolling efficiency of the magnetic material can be improved, especially for the rolling of neodymium-iron-boron (NdFeB) material, which can improve the rolling effect.

[0057] In some examples, the heating temperature of the heater 122 is 300-950°C.

[0058] The externally heated vacuum rolling mill provided in the embodiment of the present application can better isolate the rolling mill chamber 120 from the external environment through the arrangement of the preparation chamber 110 and the cooling discharge chamber 130, thereby facilitating the rolling mill chamber 120 to be in a low-oxygen state, facilitating the continuous processing of materials, and improving the processing efficiency of magnetic materials.

[0059] In a feasible embodiment, the rolling mill chamber 120 also includes: a cooling jacket, which is sleeved on the end of the rolling mill roller 123; wherein, there are two rolling mill rollers 123, and the two rolling mill rollers 123 form a rolling zone, and the heating element 129 is arranged in the rolling zone and sleeved on the outer sides of the two rolling mill rollers 123, and in the length direction of the rolling mill roller 123, the area corresponding to the rolling mill roller 123 and the heating end forms a high-temperature rolling zone 1231, and the area corresponding to the rolling mill roller 123 and the cooling jacket forms a forced cooling zone 1232, and a natural cooling zone 1233 is formed on the rolling mill roller 123 between the high-temperature rolling zone 1231 and the forced cooling zone 1232.

Based on this, the high-temperature rolling zone is in contact with the product to be rolled, so as to improve the rolling efficiency. By forming a natural cooling zone 1233 between the high-temperature rolling zone 1231 and the forced cooling zone 1232 on the rolling mill roller 123, a temperature transition zone can be formed on the roller body of the rolling mill roller 123, which not only ensures that the rolling mill roller 123 can efficiently roll the product to be rolled, but also prevents the driving components of the rolling mill roller 123 from being damaged by high temperature.

The processor is connected to the temperature sensor to obtain the temperature of the end of the rolling mill roller 123. When the temperature is too high, the flow rate of the cooling medium supplied to the cooling jacket may be increased to improve the cooling efficiency of the rolling mill roller 123 and avoid damage to the rolling mill roller 123. At the same time, the processor may also be connected to the heating element 129 to control the heating power of the heating element 129 and avoid excessive temperature of the heating element 129.

[0064] In some examples, the mill chamber 120 may further include: a heat preservation chamber 1210, which is sleeved on the outside of the heating element 129, so that more heat energy of the heating element 129 can be collected on the mill roller 123, thereby improving the heating efficiency.

[0067] In this technical solution, the feed channel 1251 and the heater 122 are covered by the thermal insulation layer 127, which can reduce the overflow of heat energy.

[0068] In this technical solution, the rolling mill chamber 120 may further include a first gate valve 128 , which is configured to facilitate cutting off the connection between the rolling mill chamber body 121 and the cooling discharge chamber 130 , thereby facilitating maintaining a low oxygen environment in the rolling mill chamber body 121 .
