Description

Technical Field

[0001] This utility model relates to the field of steel tapping temperature measurement technology, and more specifically, to a steel tapping temperature monitoring device. Background Technology

[0002] Steel tapping temperature measurement is a crucial step in the steelmaking process. Specifically, it refers to the temperature measurement and sampling performed after the converter blowing process is completed and the lance is lifted during steelmaking. This is to determine whether the composition and temperature of the molten steel meet the tapping requirements before the steel is tapped. This step is essential for ensuring the smooth progress of the steelmaking process and the quality of the final product. Existing steel tapping temperature monitoring devices, due to the limitations of their measuring end positions, cannot measure the temperature of molten steel in different areas of the furnace. The temperature of molten steel in different areas may vary, making it difficult to obtain comprehensive steel temperature information and affecting the accuracy and reliability of steel tapping temperature measurement. Based on this, this utility model designs a steel tapping temperature monitoring device to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a steel tapping temperature monitoring device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A steel tapping temperature monitoring device includes a support, a transmission base, a positioning plate, and a heat-resistant cylinder. The support is equipped with a lifting drive assembly for driving the transmission base to move up and down. The positioning plate is rotatably connected to the bottom of the transmission base via an assembly shaft. An eccentric seat is fixedly installed on the outer side of the positioning plate. The transmission base is equipped with a rotation drive assembly for driving the positioning plate and the eccentric seat to rotate. The heat-resistant cylinder is fixedly inserted through the eccentric seat. An infrared temperature detector is fixedly installed inside the heat-resistant cylinder via a heat insulation seat. A heat insulation sleeve is provided on the inner side of the heat-resistant cylinder. A heat-conducting temperature measuring column is fixedly inserted through the bottom of the heat-resistant cylinder at a position corresponding to the infrared temperature detector.

[0006] As a preferred embodiment of this utility model, the lifting drive assembly includes a telescopic cylinder and a connecting block. The telescopic cylinder is fixedly installed on the upper end of the bracket, and the transmission seat is fixedly installed on the telescopic end of the telescopic cylinder through the connecting block.

[0007] As a preferred embodiment of this utility model, a guide block is fixedly installed on the outer side of the transmission seat, and the guide block is slidably sleeved on the outside of the bracket.

[0008] As a preferred embodiment of this utility model, the number of guide blocks is two, and the guide blocks are symmetrically distributed.

[0009] As a preferred embodiment of this utility model, the rotary drive assembly includes a motor and a positioning gear. The motor is fixedly mounted on a transmission base, and the positioning gear is fixedly connected to the drive shaft of the motor. A gear ring is fixedly sleeved on the assembly shaft, and the positioning gear meshes with the gear ring.

[0010] As a preferred embodiment of this invention, the outer diameter of the gear ring is larger than the diameter of the positioning gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a telescopic cylinder to drive the transmission seat and the heat-resistant cylinder to descend, allowing the heat-resistant cylinder and the thermally conductive temperature measuring column to extend into the molten steel inside the furnace. The depth of the thermally conductive temperature measuring column within the molten steel can be adjusted. A motor drives a positioning gear to rotate, which in turn rotates the positioning disc, eccentric seat, and heat-resistant cylinder. This allows for adjustment of the horizontal position of the thermally conductive temperature measuring column within the molten steel. The molten steel temperature is transferred to the thermally conductive temperature measuring column, and its temperature is measured using an infrared temperature detector inside the heat-resistant cylinder. By adjusting the depth and horizontal position of the thermally conductive temperature measuring column, it is convenient to measure the temperature of the molten steel in different areas of the furnace, facilitating comprehensive acquisition of molten steel temperature information and ensuring the accuracy and reliability of the temperature measurement during steel tapping.

[0019] like Figures 1 to 4 As shown, this utility model provides a steel tapping temperature monitoring device, including a bracket 1, a transmission seat 2, a positioning plate 4, and a heat-resistant cylinder 6. The bracket 1 is provided with a lifting drive assembly 3 for driving the transmission seat 2 to move up and down. The positioning plate 4 is rotatably connected to the bottom end of the transmission seat 2 through an assembly shaft 201. An eccentric seat 401 is fixedly installed on the outside of the positioning plate 4. The transmission seat 2 is provided with a rotation drive assembly 5 for driving the positioning plate 4 and the eccentric seat 401 to rotate. The heat-resistant cylinder 6 is fixedly inserted through the eccentric seat 401. An infrared temperature detector 8 is fixedly installed inside the heat-resistant cylinder 6 through a heat insulation seat 601. A heat insulation sleeve 602 is provided on the inner side of the heat-resistant cylinder 6. The heat insulation seat 601 and the heat insulation sleeve 602 can play a good heat insulation and protection role. A heat-conducting temperature measuring column 7 is fixedly inserted through the bottom of the heat-resistant cylinder 6 at the corresponding position of the infrared temperature detector 8.

[0020] Among them, such as Figure 2 As shown, the lifting drive assembly 3 includes a telescopic cylinder 301 and a connecting block 302. The telescopic cylinder 301 is fixedly installed on the upper end of the bracket 1, and the transmission seat 2 is fixedly installed on the telescopic end of the telescopic cylinder 301 through the connecting block 302. The telescopic cylinder 301 can be used to drive the transmission seat 2 and the heat-resistant cylinder 6 to perform lifting and lowering activities.

[0021] Among them, such as Figure 2 As shown, a guide block 202 is fixedly installed on the outer side of the transmission seat 2, and the guide block 202 is slidably sleeved on the outside of the bracket 1. There are two guide blocks 202, which are symmetrically distributed to achieve the purpose of providing good guidance for the transmission seat 2.

[0022] Among them, such as Figure 2 and Figure 4 As shown, the rotary drive assembly 5 includes a motor 501 and a positioning gear 502.

A gear ring 9 is fixedly sleeved on the assembly shaft 201, and the positioning gear 502 meshes with the gear ring 9.

[0023] Among them, such as Figure 4 As shown, the outer diameter of the toothed ring 9 is larger than the diameter of the positioning gear 502, which achieves the purpose of enabling the positioning gear 502 to drive the toothed ring 9 to rotate at a relatively slow speed.

[0024] The working principle of this utility model:

[0025] The telescopic cylinder 301 drives the transmission seat 2 and the heat-resistant cylinder 6 to descend, allowing the heat-resistant cylinder 6 and the heat-conducting temperature measuring column 7 to extend into the molten steel inside the furnace. The depth of the heat-conducting temperature measuring column 7 in the molten steel can be adjusted. The motor 501 drives the positioning gear 502 to rotate, and the gear ring 9 drives the positioning disk 4, the eccentric seat 401, and the heat-resistant cylinder 6 to rotate, adjusting the horizontal position of the heat-conducting temperature measuring column 7 in the molten steel. The temperature of the molten steel is transferred to the heat-conducting temperature measuring column 7, and the temperature of the heat-conducting temperature measuring column 7 can be measured by the infrared temperature detector 8 inside the heat-resistant cylinder 6. By adjusting the depth and horizontal position of the heat-conducting temperature measuring column 7, it is convenient to measure the temperature of the molten steel in different areas of the furnace, facilitating the comprehensive acquisition of molten steel temperature information.
