Description

Technical Field

[0001] This utility model relates to the field of metallurgical furnace roller technology, and in particular to a novel iron-based composite metallurgical furnace roller. Background Technology

[0002] In the metallurgical industry, furnace rolls, as important components of heat treatment equipment, undertake multiple functions such as material heating, transmission, and support. However, in the existing design and use of metallurgical furnace rolls, a serious problem is often encountered: the uneven temperature between the inside and outside of the furnace roll leads to a large temperature difference, which seriously affects the service life of the furnace roll and metallurgical efficiency.

[0003] Traditional furnace roll designs often overlook the temperature difference between the inside and outside of the roll. As a result, during the metallurgical process, the temperature inside the roll is relatively low due to the lag and obstruction of heat transfer, while the outside of the roll is directly exposed to a high-temperature environment and its temperature rises rapidly. This temperature inconsistency not only reduces the overall heating efficiency of the furnace roll, but also makes it highly susceptible to cracking and other damage under the combined effects of high temperature and mechanical stress. Utility Model Content

[0004] The purpose of this invention is to provide a novel iron-based composite metallurgical furnace roller to solve the problems mentioned in the background art and facilitate its widespread application.

[0005] A novel iron-based composite metallurgical furnace roller includes a drive shaft, a support assembly on the drive shaft, a heat equalization assembly on the support assembly, and a ventilation assembly on the heat equalization assembly.

[0006] The support assembly includes a plurality of evenly arranged support rods fixedly mounted on a drive shaft. A support roller is sleeved on the drive shaft, and the end of each support rod away from the drive shaft is fixedly mounted on the inner wall of the support roller.

[0007] Furthermore, the heat equalization assembly includes a plurality of uniformly arranged heat equalization holes opened on the support roller, a plurality of uniformly arranged heat equalization rods inserted on the support roller, a heat equalization plate fixedly provided at one end of each heat equalization rod, and the heat equalization plate being disposed inside the support roller.

[0008] Furthermore, the breathable component includes a roller body fixedly mounted on a support roller, with a plurality of evenly arranged breathable holes on the outer wall of the roller body, and filter plates symmetrically arranged on the inner wall of the roller body.

[0009] Furthermore, the heat-equalizing rod and heat-equalizing plate are made of copper.

[0010] Furthermore, there are several heat-equalizing rods and heat-equalizing plates, which are arranged equidistantly and symmetrically.

[0011] Furthermore, there are several support rods, which are equidistantly arranged around the drive shaft.

[0012] As an improvement, the beneficial effects of this utility model are as follows:

[0013] This invention relates to a novel iron-based composite metallurgical furnace roller. By creating heat-distributing holes on the support roller and inserting heat-distributing rods and plates, the heat inside the furnace roller can be distributed more rapidly and evenly. In particular, the heat-distributing rods and plates are made of copper, a material with excellent thermal conductivity, further improving heat transfer efficiency. This design not only significantly improves the heating efficiency of the furnace roller but also ensures the uniformity of temperature inside and outside the roller, extending its service life.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Identical components are indicated by the same reference numerals.

[0025] This embodiment provides a novel iron-based composite metallurgical furnace roller, including a drive shaft 1, a support assembly 2 on the drive shaft 1, a heat equalization assembly 3 on the support assembly 2, and a ventilation assembly 4 on the heat equalization assembly 3.

[0026] In this embodiment, the support assembly 2 is a key component connecting the drive shaft 1 to the subsequent components. It mainly consists of multiple evenly arranged support rods 201 and a support roller 202 sleeved on the drive shaft 1. One end of the support rod 201 is fixedly mounted on the drive shaft 1, while the other end extends into and is fixed to the inner wall of the support roller 202. This design not only enhances the structural stability of the entire furnace roller but also ensures that the drive shaft 1 can smoothly drive the entire furnace roller to rotate.

[0027] Specifically, there are several support rods 201, which are equidistantly arranged around the drive shaft 1 to form a uniform support structure. This design helps to distribute the weight of the support roller 202, avoid damage caused by excessive local stress, and also helps to improve the rotational balance of the furnace roller.

[0028] In this embodiment, the heat equalization component 3 aims to ensure the uniformity of temperature inside and outside the furnace roller, preventing large temperature differences between the inside and outside of the furnace roller and thus preventing cracking of the furnace roller. It mainly consists of multiple uniformly arranged heat equalization holes 301 opened on the support roller 202, and multiple heat equalization rods 302 and heat equalization plates 303 inserted into the support roller 202.

[0029] The heat equalization hole 301 helps to transfer heat evenly, while the heat equalization rod 302 and heat equalization plate 303 are made of copper with excellent thermal conductivity. They are inserted into the support roller 202 and cooperate with the heat equalization hole 301 to further improve the heat transfer efficiency and uniformity.

[0030] In addition, there are several heat-dissipating rods 302 and heat-dissipating plates 303, which are arranged equidistantly and symmetrically at the center. This design enhances the heat dissipation effect.

[0031] In this embodiment, the ventilated component 4 is mainly used to improve the permeability of the metallurgical furnace, promote the circulation and exchange of gas inside the furnace, and further ensure the uniformity of temperature inside and outside the furnace roller. It mainly consists of a roller body 401 fixedly mounted on the support roller 202, a plurality of evenly arranged vent holes 402 opened on the outer wall of the roller body 401, and filter plates 403 symmetrically arranged on the inner wall of the roller body 401.

[0032] The vent holes 402 allow gas inside the furnace to circulate and exchange through the roller body 401, thereby improving the permeability of the furnace. The filter plate 403 helps prevent impurities inside the furnace from entering the roller body 401, ensuring the cleanliness and service life of the venting assembly 4.

[0033] In addition, the symmetrical arrangement of the filter plates 403 helps to improve the structural symmetry of the roller body 401, further enhancing the overall stability and durability of the furnace roller.

[0034] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
