Description

Technical Field

[0001] The utility model belongs to the technical field of iron and steel metallurgy, and particularly relates to a device for both temperature measurement and sampling in a refining furnace. Background Technique

[0002] At present, temperature measurement and sampling in a refining furnace usually need to be carried out separately. Generally, a temperature measurement gun is used for temperature measurement, and a special sampling rod is used for sampling. Both require manual operation. The temperature measurement time is 3 - 4 seconds, and when measuring temperature, it is inserted into the molten steel by 30 - 35 cm. The sampling time is 3 - 4 seconds, and when sampling, the insertion depth into the molten steel is 30 - 35 cm. The operation time of both is similar, and the insertion depth is the same.

[0003] In an LF furnace, it takes 40 minutes to smelt one heat of steel, and there are about 5 temperatures per heat. In an RH furnace, the number of times of simultaneous temperature measurement + sampling is more than two. During smelting, the operator will issue instructions for temperature measurement and sampling. The furnace front worker first uses a temperature measurement gun to measure the temperature, and then uses a sampling rod to take a sample. This repeated operation not only wastes time and reduces work efficiency, but also the operator needs to enter the high-temperature area for detection multiple times, which undoubtedly increases the risk of heat stroke and scalding, and endangers the life, health and safety of the operator. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems of time-consuming, laborious and high risk caused by separate operation of temperature measurement and sampling in the existing refining furnace, and provides a device for both temperature measurement and sampling in a refining furnace, which reduces the auxiliary time, improves the production efficiency, reduces the labor intensity, reduces the time of personnel in the high-temperature area, and reduces the risk of being scalded.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A device for both temperature measurement and sampling in a refining furnace includes a temperature measurement gun and a sampler that cooperate with each other. The temperature measurement gun includes a temperature measurement rod at the front end, a connecting rod in the middle, and an operation ring at the rear end. A downward-extending mounting bracket is fixed on one side of the connecting rod close to the temperature measurement rod. The bottom of the mounting bracket is hinged to one end of the sampler through a movable shaft. The other end of the sampler is a sampling end, and a buckle device is connected to the sampler. The sampler is fixedly connected to the temperature measurement gun through the buckle device.

[0007] Further, the axis of the mounting bracket is perpendicular to the axis of the connecting rod, and when the sampling end of the sampler is in the same direction as the temperature measurement rod of the temperature measurement gun, the axis of the sampler is parallel to the axis of the temperature measurement gun up and down.

[0008] Further, a limiting boss is provided at the connection between the temperature measurement rod and the connecting rod. The diameter of the limiting boss is larger than the diameter of the connecting rod to prevent the sampler from turning over too much and touching the temperature measurement rod.

[0009] Furthermore, the operating ring is connected to the connecting rod through a fixed block, one side of the fixed block is a flat surface and the other side is an arcuate surface, the flat surface is connected to the end of the connecting rod, the arcuate surface is connected to the operating ring and the curvature of the two is the same, and the arc opening of the operating ring is set toward the connecting rod.

[0010] Furthermore, the snap-on device includes a connected fixed buckle and a movable buckle, the fixed buckle is mounted on the sampler and the two are fixedly connected, the movable buckle is an open snap-on structure, and when the sampler is rotated to an appropriate position, the movable buckle is connected to the temperature gun.

[0011] In the technical solution of the present invention, a sampling rod is added to the temperature measuring gun, which is slightly shorter than the temperature measuring gun head. When it is necessary to measure temperature and take samples at the same time, the temperature measuring probe and the sampling probe are put on at the same time, and temperature measurement and sampling are carried out simultaneously; when sampling is not needed, the sampling rod can be rotated to the upper part of the temperature measuring gun and fixed with a buckle. When needed, it can be rotated to the bottom of the temperature measuring gun and fixed, and temperature measurement and sampling can be carried out simultaneously. The device of the present invention can effectively save time for temperature measurement and sampling, improve work efficiency, reduce work intensity, reduce the time people spend in high-temperature places, and reduce the risk of burns. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is a schematic diagram of the device structure when sampling is not required in the present invention. DETAILED DESCRIPTION Example

[0014] In order to make the present invention more clear, the present invention is further described below with reference to the accompanying drawings. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0015] See also Figure 1 and Figure 2 A device for temperature measurement and sampling for a refining furnace, comprising a temperature measuring gun 1 and a sampler 2 that cooperate with each other, characterized in that:

[0016] The temperature measuring gun 1 includes a temperature measuring rod 11 at the front end, a connecting rod 12 in the middle, and an operating ring 13 at the rear end. The operating ring 13 is connected to the connecting rod 12 through a fixing block 16. One side of the fixing block 16 is a flat surface 16a and the other side is a curved surface 16b. The flat surface 16a is connected to the end of the connecting rod 12. The curved surface 16a is connected to the operating ring 13 and the curvature of the two is the same. The curved opening of the operating ring 13 is set toward the connecting rod 12.

[0017] On one side of the connecting rod 12 close to the temperature measuring rod 11, a downward-extending mounting bracket 14 is fixed. The bottom of the mounting bracket 14 is hinged to one end of the sampler 2 through a movable shaft 3. The axis of the mounting bracket 14 is perpendicular to the axis of the connecting rod 12. And when the sampling end 21 of the sampler 2 is in the same direction as the temperature measuring rod 11 of the temperature measuring gun 1, the axis of the sampler 2 is parallel to the axis of the temperature measuring gun 1 up and down.

[0018] The other end of the sampler 2 is the sampling end 21, and a buckle device 4 is connected to the sampler 2. The sampler 2 is fixedly connected to the temperature measuring gun 1 through the buckle device 4. The buckle device 4 includes a fixed buckle 41 and a movable buckle 42 connected to each other. The fixed buckle 41 is sleeved on the sampler 2 and the two are fixedly connected. The movable buckle 42 is an open-type buckle structure. When the sampler 2 rotates to an appropriate position, the movable buckle 42 is clamped on the temperature measuring gun 1.

[0019] In this embodiment, a limiting boss 15 is provided at the connection between the temperature measuring rod 11 and the connecting rod 12. The diameter of the limiting boss 15 is larger than the diameter of the connecting rod 12 to prevent the sampler from flipping too much and touching the temperature measuring rod.

[0020] In this embodiment, a sampler 2 is added to the temperature measuring gun 1. The sampler 2 can rotate, its length is slightly shorter than that of the temperature measuring gun, and a device that can be fixedly disassembled is added. When temperature measurement and sampling need to be carried out simultaneously, the sampler 2 can be rotated around the movable shaft 3 until the sampling end 21 is in the same direction as the temperature measuring rod 11. After being fixed by the buckle device 4, temperature measurement and sampling can be carried out. When only temperature measurement is required without sampling, the sampler 2 is rotated around the movable shaft 3 again until the sampling end 21 is close to the operation ring 13 side, and then fixed by the buckle device 4.

[0021] The device of the present utility model effectively improves the production efficiency, reduces the labor intensity, reduces the time of personnel in high-temperature places, and reduces the risk of personnel being scalded.

[0022] In addition to the above embodiments, the present utility model can also have other implementation manners. All technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present utility model.
