A temperature measurement system that does not damage the ladle structure.

Abstract

This invention provides a temperature measurement system that does not damage the ladle structure, and includes a ladle and a temperature measuring member. The ladle includes a steel shell, a refractory layer provided inside the steel shell, and a permanent layer provided between the steel shell and the refractory layer. The outer wall of the steel shell itself has an exhaust hole, which communicates with the outer wall of the permanent layer. The cross-section of the temperature measuring member is smaller than the exhaust hole and can be inserted into the exhaust hole to perform temperature measurement. A projection is provided on the outside of the temperature measuring member, which abuts against the wall of the exhaust hole to ensure firm fixation. A gap is formed between the non-protruding part of the outside of the temperature measuring member and the wall of the exhaust hole, which is used for exhaust. Because this invention installs the temperature measuring member in the exhaust hole of the steel shell itself, it does not damage the ladle structure. When the temperature measuring element is attached, the protrusion contacts the wall of the exhaust hole, allowing the temperature measuring element to be fixed to the exhaust hole. A gap is formed between the non-protruding part of the temperature measuring element and the wall of the exhaust hole, and because the air pressure inside the ladle is high, the gas inside the ladle is smoothly discharged through this gap due to the pressure action of the air pressure.

Description

Technical Field

[0001] The present invention relates to the technical field of ladles, and particularly to a temperature measurement system that does not damage the ladle structure.

Background Art

[0002] A ladle is a tool for taking molten metal and pouring it. It is provided with a steel shell, a permanent layer, and a refractory layer in order from the outside to the inside. The steel shell itself has exhaust holes that lead to the outer wall of the permanent layer. When high-temperature molten metal is taken into the ladle, the high-temperature molten metal contacts the refractory layer, which may damage the refractory layer. If the refractory layer is burned out by the high-temperature molten metal, serious accidents such as the ladle breaking may occur. In order to detect damage to the refractory layer at an early stage, the prior art measures the temperature of the refractory layer. Specifically, a thermocouple is inserted into the ladle to measure the temperature inside the ladle. If the measured temperature exceeds the danger value, it is determined that the refractory layer is already damaged, and the refractory layer needs to be repaired or replaced. The exhaust holes of the steel shell itself are used for exhaust and must not be clogged. Therefore, in the prior art, the thermocouple is not installed in the exhaust hole, and a separate hole is drilled on the steel shell to install the thermocouple, but there is a risk of damaging the ladle structure.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The problem to be solved by the present invention is to provide a temperature measurement system that does not damage the ladle structure.

Means for Solving the Problems

[0004] To solve the above-mentioned problems, the temperature measurement system provided by the present invention, which does not damage the ladle structure, includes a ladle and a temperature measuring member. The ladle has a steel shell, a refractory layer provided inside the steel shell, and a permanent layer provided between the steel shell and the refractory layer. The outer wall of the steel shell itself has an exhaust hole, which communicates with the outer wall of the permanent layer. The cross-section of the temperature measuring member is smaller than the exhaust hole and is inserted into the exhaust hole to perform temperature measurement. A projection is provided on the outside of the temperature measuring member, and this projection contacts the wall of the exhaust hole to ensure firm fixation. A gap is formed between the non-protruding portion on the outside of the temperature measuring member and the wall of the exhaust hole for use as exhaust.

[0005] Furthermore, polygonal nuts are laid on the outer wall of the temperature measuring member provided by the present invention, with the corners of the polygonal nuts being the protrusions of the present invention, and the sides of the polygonal nuts being the non-protruding parts of the present invention.

[0006] Furthermore, the temperature measuring element is inserted into the exhaust port and reaches the outer wall of the permanent layer.

[0007] Furthermore, the temperature measuring element is a thermocouple.

[0008] Furthermore, the invention includes a temperature measuring box, the temperature measuring box is provided with a temperature collection module, and the temperature measuring member provided by the present invention is electrically connected to the temperature collection module in the temperature measuring box.

[0009] Furthermore, the temperature collection module has a built-in wireless communication device and possesses wireless communication capabilities.

[0010] Furthermore, there are multiple exhaust vents.

[0011] Furthermore, one side of the steel shell is designated as the horizontal surface, and the steel shell undergoes the firing process in a horizontal position with the horizontal surface facing downwards, while the side of the steel shell that is not the horizontal surface has the exhaust holes provided by the present invention.

[0012] Furthermore, the top of the steel shell is a waste discharge port, the area less than 800 mm below the waste discharge port on the outer wall of the steel shell is a steel slag scattering hazard area, and the part of the side that is not a horizontal surface provided by the present invention, other than the steel slag scattering hazard area, has an exhaust port provided by the present invention.

[0013] Furthermore, the outer wall of the steel shell is provided with a left overhang and a right overhang, and the area lower than the left overhang and the right overhang is a semi-recessed area, and the portion of the side that is not a horizontal surface provided by the present invention, other than the semi-recessed area, has an exhaust port provided by the present invention. [Effects of the Invention]

[0014] In conventional technology, a hole is drilled in the steel shell to attach the temperature measuring member, whereas in this invention, the temperature measuring member is attached to the exhaust hole of the steel shell itself, thus not damaging the structure of the ladle. To solve the exhaust problem of the exhaust hole, this invention attaches a projection to the outside of the temperature measuring member. When the temperature measuring member is attached, the projection abuts against the wall of the exhaust hole and is fixed in place, so the temperature measuring member is fixed inside the exhaust hole, and a gap for exhaust is formed between the non-protruding part of the outside of the temperature measuring member and the wall of the exhaust hole, the air pressure inside the ladle increases, and the gas inside the ladle is smoothly discharged through this gap by the pressure action of the air pressure, thus solving the exhaust problem. Furthermore, because the temperature measuring member is fixed inside the exhaust hole by the projection, it is prevented from shifting radially and interfering with the discharge of gas. [Brief explanation of the drawing]

[0015] [Figure 1] This diagram shows a temperature measurement system that does not damage the ladle structure. [Figure 2] This is a diagram showing a longitudinal cross-section of the side wall of a ladle. [Figure 3] This diagram shows a hexagonal nut and an exhaust port. [Modes for carrying out the invention]

[0016] The present invention will be described in detail below using specific examples.

[0017] As shown in Figure 1, the ladle 1 has a steel shell 10. As shown in Figure 2, a refractory layer 19 is provided on the inside of the steel shell 10, and a permanent layer 18 is provided between the steel shell 10 and the refractory layer 19, with the refractory layer 19 surrounding and forming a cavity 162. The outer wall of the steel shell 10 itself has a plurality of exhaust holes 15, and the exhaust holes 15 communicate from the outer wall of the steel shell 10 to the outer wall of the permanent layer 18 to discharge gas from inside the ladle 1. As shown in Figure 1, a temperature measuring box 2 made of insulating material is provided on the outer wall of the steel shell 10, and a temperature collection module is provided inside the temperature measuring box 2. A thermocouple 3 is provided on the outside of the temperature measuring box 2, and the thermocouple 3 is electrically connected to the temperature collection module inside the temperature measuring box 2 to transmit the temperature data of the ladle to the temperature collection module. A wireless communication device is built into the temperature collection module to transmit the received temperature data of the ladle 1 to a higher-level unit. A hexagonal nut 4 is covered on the outer wall of the thermocouple 3. As shown in Figure 3, the hexagonal nut 4 is hexagonal, with its six corners being projections 51 and its six sides being non-projecting portions 52. The cross-section of the thermocouple 3 is smaller than the exhaust hole 15. The thermocouple 3 is inserted into the exhaust hole 15 and reaches the outer wall of the permanent layer 18 to perform temperature measurement. The thermocouple 3 is fixed in contact with the hole wall of the exhaust hole 15 through the projections 51 of the hexagonal nut 4, and a gap 6 is formed between the non-projecting portions 52 of the hexagonal nut 4 and the hole wall of the exhaust hole 15. The air pressure inside the ladle 1 is high, and the gas inside the ladle 1 is smoothly discharged through the gap 6 due to the pressure action of the air pressure. The temperature measurement system provided by the present invention consists of a ladle 1, a temperature measurement box 2, a temperature collection module, a thermocouple 3, and a hexagonal nut 4 on it.

[0018] As shown in Figure 1, an upper overhang 11, a lower overhang 12, a left overhang 13, and a right overhang 14 are provided on the outer wall of the steel shell 10. As shown in Figure 1, a hanging hook 17 is provided on the outer wall of the back of the steel shell 10, and the steel shell 10 has a front surface (not shown). When the ladle 1 undergoes the firing process, it needs to be lying on its side to receive firing from the firing device, so one side of the ladle 1 is designated as the lying surface. In this embodiment, the ladle 1 has the side wall of the front of the steel shell 10 as the lying surface, and the lying position is achieved with the front of the steel shell 10 facing downwards. Therefore, when measuring the temperature, the thermocouple 3 is not inserted through the exhaust hole 15 on the front of the steel shell 10, but needs to be inserted through the exhaust hole 15 on the other side of the steel shell 10, preferably through the exhaust hole 15 on the back of the steel shell 10. A waste discharge port 161 is provided at the top of the ladle 1. When the slag in the cavity 162 of the ladle is discharged to the outside through the waste discharge port 161, it is likely to be scattered to an area less than 800 mm below the waste discharge port 161 on the outer wall of the steel shell 10. Since this area is a slag scattering hazard area, the thermocouple 3 should not be inserted into an exhaust port 15 located within the slag scattering hazard area, but into an exhaust port 15 located outside the slag scattering hazard area. Before the ladle 1 undergoes the melting process, it is usually transported to the melting site by a transport vehicle, half-embedded in a pit on the transport vehicle. Since the area below the left overhang portion 13 and the right overhang portion 14 of the outer wall of the steel shell 10 is a half-embedded area, the thermocouple 3 should not be inserted into an exhaust port 15 located within the half-embedded area, but into an exhaust port 15 located outside the half-embedded area.

[0019] The foregoing is for the purpose of illustrating embodiments of the present invention and does not limit the scope of protection of the present invention. Those skilled in the art will know that non-essential modifications or substitutions made based on the invention should still fall within the scope of protection of the present invention.
