[0003] The present invention introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This part of the present invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.
[0005] In view of this, embodiments of this application propose a rolling mill roll, comprising:
[0006] A roller body, wherein a cavity is formed inside the roller body, a heating zone and a cooling zone are formed on the roller body, the cooling zone is located on both sides of the heating zone, and the cavity extends from one end of the roller body to the heating zone;
[0007] A heating element is disposed within the roller body and is used to provide heat energy to the heating zone of the roller body.
[0008] In one possible implementation, the cavity is arranged along the length of the roller and extends from one end of the roller to the middle of the roller.
[0009] In one feasible implementation, the mill rolls further include:
[0010] The cooling component includes a forced cooling zone and a natural cooling zone. The natural cooling zone is adjacent to the heating zone, and the forced cooling zone is adjacent to the natural cooling zone. The cooling component is connected to the forced cooling zone.
[0011] In one feasible implementation, the cooling element includes:
[0012] A cooling jacket is fitted over the forced cooling zone of the roller body.
[0013] In one feasible implementation, the heating element includes a heating resistance wire disposed within the cavity.
[0014] In one feasible implementation, the heating element further includes:
[0015] A heat insulation sleeve is fitted onto the heating resistance wire, and the heat insulation sleeve is positioned opposite to the cooling zone.
[0016] In one feasible implementation, the inner wall of the end of the cavity is recessed, and the recessed inner wall is used to position the heating resistance wire.
[0017] In one feasible embodiment, the mill roll further includes an end cap connected to the roll body, and the heating element passing through the end cap and disposed within the cavity.
[0018] In one possible implementation, the mill roll further includes a heat-insulating coating applied to the inner wall of the cavity in the region opposite to the cooling zone.
[0019] In one feasible embodiment, the mill roll further includes a heat-conducting element filled in the cavity and located between the heating element and the inner wall of the roll body.
[0020] Compared with the prior art, the present invention has at least the following beneficial effects:
[0021] The rolling mill roll provided in this application embodiment includes a roll body and a heating element. The roll body contains a cavity, a heating zone, and a cooling zone. The heating element is disposed within the roll body. Based on this, during the operation of the rolling mill roll, such as during the rolling of magnetic materials, the heating element can be activated before rolling. The heating element preheats the roll body. When the rolling roll contacts the magnetic material, the magnetic material contacts the higher-temperature roll body, reducing heat loss and making the magnetic material more compact. This avoids the heated material from contacting the lower-temperature roll surface, instead ensuring contact with the higher-temperature roll body, thus improving rolling efficiency. Furthermore, the roll body includes a cooling zone and a heating zone. The heating zone of the roll body is used for contact with the magnetic material, ensuring rolling efficiency. The formation of the cooling zone prevents the high temperature of the roll body from affecting other components of the rolling equipment, ensuring smooth rolling.

[0029] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.
[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.
[0031] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.
[0032] like Figure 1 and Figure 2 As shown in the embodiment of this application, a rolling mill roll is proposed, including: a roll body 110, a cavity 111 formed inside the roll body 110, a heating zone 112 and a cooling zone 113 formed on the roll body 110, the cooling zone 113 being located on both sides of the heating zone 112, and the cavity 111 extending from one end of the roll body 110 to the heating zone 112; and a heating element 120 disposed inside the roll body 110 for providing heat energy to the heating zone 112 of the roll body 110.
[0033] The rolling mill roll provided in this embodiment includes a roll body 110 and a heating element 120. The roll body 110 has a cavity 111, a heating zone 112, and a cooling zone 113. The heating element 120 is disposed in the roll body 110. Based on this, during the operation of the rolling mill roll, such as during the rolling of magnetic materials, the heating element 120 can be turned on before rolling. The heating element 120 can preheat the roll body 110. When the rolling roll comes into contact with the magnetic material, it can make the magnetic material come into contact with the higher temperature roll body 110, reducing the loss of heat energy of the magnetic material, making the magnetic material more compact, and avoiding the heated material to be rolled from coming into contact with the lower temperature roll surface, but instead coming into contact with the higher temperature roll body 110, thus improving the rolling efficiency. Furthermore, the roll body 110 includes a cooling zone 113 and a heating zone 112. The heating zone 112 of the roll body 110 is used to contact the magnetic material to ensure rolling efficiency. The formation of the cooling zone 113 prevents the high temperature of the roll body 110 from affecting other components of the rolling equipment, thus ensuring the smooth progress of rolling.
[0034] Understandably, during the operation of the rolling mill rolls, the preheating temperature of the magnetic material is 400~900℃, while the heating temperature of the rolling mill rolls is 350~900℃. Based on this, the rolling efficiency of the magnetic material can be improved, especially when used for rolling neodymium-iron-boron (NdFeB) materials, which can improve the rolling effect.
[0035] like Figure 1 and Figure 2 As shown, in one possible embodiment, the cavity 111 is arranged along the length of the roller 110 and extends from one end of the roller 110 to the middle of the roller 110.
[0036] In this technical solution, the cavity 111 is further provided in a shape. The cavity 111 is arranged along the length direction of the roller 110 and extends from one end of the roller 110 to the middle of the roller 110. Based on this, it is convenient to extend the heating element 120 to the middle of the roller 110, so that the heating element 120 can provide heat energy to the heating zone 112 of the roller 110.
[0037] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the mill roll further includes a cooling element 130, the cooling zone 113 includes a forced cooling zone 1132 and a natural cooling zone 1131, the natural cooling zone 1131 is disposed adjacent to the heating zone 112, the forced cooling zone 1132 is disposed adjacent to the natural cooling zone 1131, and the cooling element 130 is connected to the forced cooling zone 1132.
[0038] In this technical solution, the mill roll may also include a cooling element 130. The cooling zone 113 includes a forced cooling zone 1132 and a natural cooling zone 1131. The heating element 120 is disposed in the cavity 111 and is disposed opposite to the heating zone 112. That is, when the heating element 120 is turned on, the heating element 120 can provide heat energy to the heating zone 112. The position of the natural cooling zone 1131 above the roll body 110 can be naturally heated by heat exchange with the environment. Furthermore, a forced cooling zone 1132 is formed on the side of the forced cooling zone 1132 away from the heating zone 112. The forced cooling zone 1132 can be located at the end of the roll body 110. The cooling element 130 is disposed above the forced cooling zone 1132 to provide forced cooling to the end of the roll body 110, which can prevent the high temperature of the roll body 110 from affecting other components, such as the transmission equipment of the roll body 110.
[0039] like Figure 2 As shown, in one feasible embodiment, the cooling element 130 includes a cooling sleeve that is fitted onto the forced cooling zone 1132 of the roller body 110.
[0040] In this technical solution, the structure of the cooling component 130 is further provided. The cooling component 130 may include a cooling jacket, which is fitted on the forced cooling zone 1132 of the roller body 110, which can increase the heat exchange efficiency and cool the end of the roller body 110.
[0041] It is understandable that the interior of the cooling jacket can have flow channels for the circulation of cooling medium.
[0042] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the heating element 120 includes a heating resistance wire 121, which is arranged inside the cavity 111.
[0043] In this technical solution, the structure of the heating element 120 is further provided. The heating element 120 may include a heating resistance wire 121. When the heating resistance wire 121 is turned on, heat energy can be generated. The heating resistance wire 121 is arranged opposite to the heating zone 112. When the heating resistance wire 121 is turned on, it can provide heat energy to the heating zone 112 of the roller body 110.
[0044] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the heating element 120 further includes a heat insulation sleeve 122, which is sleeved on the heating resistance wire 121 and is disposed opposite to the cooling zone 113.
[0045] In this technical solution, the heating element 120 may also include a heat insulation sleeve 122. By placing the heat insulation sleeve 122 on the heating resistance wire 121, the heat energy supplied by the heating resistance wire 121 to the cooling zone 113 of the roller body 110 can be reduced, thereby reducing the temperature of the cooling zone 113 of the roller body 110.
[0046] It is understandable that the heating resistance wire 121 corresponding to the heating zone 112 does not need to be covered with a heat insulation sleeve 122.
[0047] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the inner wall of the end of the cavity 111 is concave, and the concave inner wall is used to position the heating resistance wire 121.
[0048] In this technical solution, the shape of the cavity 111 is further provided. The inner wall of the end of the cavity 111 is concave. This setting can make the positioning of the heating resistance wire 121 more reliable and reduce the probability of the heating resistance wire 121 becoming loose.
[0049] like Figure 2 As shown, in one feasible embodiment, the mill roll further includes: an end cover 140, the end cover 140 being connected to the roll body 110, and a heating element 120 passing through the end cover 140 and disposed within the cavity 111.
[0050] In this technical solution, the mill roll may also include an end cap 140, which is connected to the roll body 110 and can serve to seal the cavity 111, making the use of the mill roll safer.
[0051] like Figure 2 As shown, in one feasible embodiment, the mill roll further includes a heat-insulating coating 150, which is applied to the inner wall of the cavity 111 in the area opposite to the cooling zone 113.
[0052] In this technical solution, in order to further suppress the transfer of heat energy from the heating element 120 to the cooling zone 113 of the roller body 110, a heat insulation coating 150 can be applied to the inner wall of the cavity 111 in the area opposite to the cooling zone 113 to reduce the transfer of heat energy from the heating element 120 to the roller body 110, so that the heating zone 112 of the roller body 110 maintains a high temperature, while the end temperature of the roller body 110 is reduced, thus ensuring the safe operation of the equipment.
[0053] like Figure 2As shown, in one feasible embodiment, the mill roll further includes a heat-conducting element 160, which is filled in the cavity 111 and located between the heating element 120 and the inner wall of the roll body 110.
[0054] In this technical solution, the mill roll may also include a heat-conducting element 160, which is arranged between the heating element 120 and the roll body 110. This arrangement facilitates the transfer of heat energy from the heating element 120 to the heating zone 112 of the roll body 110, thereby increasing the temperature of the heating zone 112 and enabling the material to come into contact with the higher-temperature roll body 110.
