Description

Technical Field

[0001] The utility model belongs to the technical field of main iron channels, and in particular relates to a main iron channel temperature monitoring device. Background Art

[0002] In the steel production process, temperature control of the main iron ditch is crucial to ensuring product quality and production efficiency. The working layer of the main iron ditch is mainly made of refractory materials and forms a barrier. The molten iron is in this barrier for a long time. By detecting the temperature of the working layer, workers can control the iron tapping temperature. Traditional main iron ditch temperature monitoring usually adopts manual inspection method, that is, the operator regularly uses infrared temperature measuring guns or thermocouples and other equipment to monitor the temperature of the main iron ditch.

[0003] In a patent application filed in China with the publication number CN215103364U and titled "A Main Iron Channel Temperature Measuring Device," a copper plate for temperature measurement is fixed to the inner surface of the steel shell sidewall at each temperature measurement point in the main iron channel. The height of the copper plate is comparable to the height of the slag-iron boundary line. The copper plate has good thermal conductivity, so the thermocouple can monitor the temperature of an area the size of the copper plate, making thermocouple monitoring more comprehensive. According to the patent's specification and accompanying drawings, the patent's technical solution places the copper plate on the steel shell sidewall. However, the actual structure of the main iron channel consists of a steel shell, a permanent layer, an intermediate layer, and a working layer. During the temperature measurement process, the temperature of the working layer is primarily measured, which is different from the temperature of the steel shell. The aforementioned technical solution cannot accurately monitor the temperature of the working layer, resulting in differences in temperature measurements.

[0004] In order to solve the above problems, this application proposes a main iron channel temperature monitoring device. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The utility model provides Figures 1-8 The main iron channel temperature monitoring device shown includes a controller 5, a thermocouple sensor 7 is provided on one side of the controller 5, and a temperature sensing rod 71 is connected to the bottom of the thermocouple sensor 7. One side of the controller 5 is the working layer 1 of the main iron channel. The top of the working layer 1 is provided with a slot 8, and a support tube 6 is inserted into the slot 8. The temperature sensing rod 71 can be downwardly inserted into the support tube 6, and the outer wall of the support tube 6 is tightly fitted with the inner wall of the working layer 1.

[0029] It should be noted that a data line 3 is provided between the controller 5 and the thermocouple sensor 7, and the data line 3 is in a suspended state and does not contact the ground;

[0030] A display 4 is provided on the front surface of the controller 5. When the controller 5 is started, the thermocouple sensor 7 senses the heat of the working layer 1 through the temperature sensing rod 71. The heat is conducted to the thermocouple sensor 7 and transmits the signal to the controller 5 through the data line 3. Finally, the temperature data is displayed on the display 4. The user can know the temperature of the working layer 1 by observation and thus carry out the next step of work. It should be noted that the working principle of the thermocouple sensor 7 is the existing technology and will not be elaborated here.

[0031] Specifically, a protective cover 2 is further provided on the outside of the thermocouple sensor 7. The outer wall of the protective cover 2 is provided with a number of air holes. The protective cover 2 can protect the outer shell of the thermocouple sensor 7. During the iron-making process or daily work, molten iron and impurities will not damage and contaminate the thermocouple sensor 7, which is conducive to ensuring the long-term use of the thermocouple sensor 7 and higher safety.

[0032] like Figure 1-Figure 7 As shown, specifically, under the influence of high temperature, the working layer 1 expands and squeezes the support tube 6. The outer wall of the support tube 6 is fixed with a steel rib 61. The steel rib 61 and the main structure of the support tube 6 can be fixed by welding. The steel rib 61 plays a role in improving the strength of the support tube 6. With the auxiliary support of the steel rib 61, the support tube 6 is ensured not to be deformed, thereby providing all-round protection for the temperature sensing rod 71 to prevent the temperature sensing rod 71 from being squeezed. At the same time, the support tube 6 supports the inner wall of the working layer 1 to ensure that the working layer 1 will not be broken.

[0033] like Figure 7 and Figure 8 As shown, specifically, a plurality of support members 9 are provided inside the support tube 6, a gasket 91 is provided at one end of the support member 9, and an aluminum plate 92 is provided at the other end. The gasket 91 is an arc-shaped structure, and the outer surface of the gasket 91 is tightly fitted with the inner wall of the support tube 6;

[0034] A positioning tube 10 is further provided inside the support tube 6 , the outer wall of the positioning tube 10 is in contact with the inner wall of the support tube 6 , and one side surface of the aluminum plate 92 is in close contact with the outer wall of the positioning tube 10 .

[0035] The support member 9 is made of aluminum. During the iron-making process, the working layer 1 is affected by the high temperature of the molten iron, and the working layer 1 expands due to the heat. The support tube 6 is squeezed by the inner wall of the working layer 1, and the support tube 6 has a tendency to shrink inward, but the support tube 6 will not be deformed. The inward shrinkage tendency of the support tube 6 can push the gasket 91, the gasket 91 pushes the support member 9, the support member 9 pushes the aluminum plate 92, and the aluminum plate 92 pushes the positioning tube 10. At this time, under the support of the gasket 91, the support member 9 and the aluminum plate 92, the positioning tube 10 will not tilt, and the temperature sensing rod 71 inserted in the positioning tube 10 will not tilt or loosen.

[0036] like Figure 6 As shown, it should be noted that a buffer spring 11 is further provided inside the support tube 6 near the bottom end of the positioning tube 10, and a metal ball 12 is provided on the top of the buffer spring 11. The central axis of the metal ball 12 is in a straight line with the central axis of the positioning tube 10;

[0037] Among them, after the temperature sensing rod 71 is inserted downward into the positioning tube 10, during the process of continuing to insert downward, after the bottom end of the temperature sensing rod 71 reaches the bottom end of the positioning tube 10, the bottom of the temperature sensing rod 71 contacts the metal ball 12. After the metal ball 12 is squeezed, it simultaneously squeezes the buffer spring 11, and the buffer spring 11 is compressed, thereby having a buffering effect, avoiding the problem of damaging the temperature sensing rod 71 during the insertion process of the temperature sensing rod 71.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
