Description

Technical Field

[0001] The utility model relates to the field of stainless steel smelting equipment, in particular to a crystallizer with a temperature measuring function. Background Art

[0002] In the continuous casting process, steel leakage is a typical production accident. It will not only reduce the productivity of the continuous casting process, damage the equipment, but also may cause harm to the on-site operators. Therefore, it is very necessary to add a steel leakage prediction function to the continuous casting machine of the steelmaking plant to control the occurrence of steel leakage accidents, reduce losses, and increase production. The crystallizer copper plate with temperature measurement function is an important component of the steel leakage prediction function.

[0003] A Chinese patent with authorization announcement number CN201201041Y discloses a slab continuous casting crystallizer copper plate thermocouple installation structure, including a sleeve, a thermocouple and a thermocouple locking nut. The sleeve is installed in a thermocouple fixing hole on the back plate of the crystallizer, and the thermocouple is inserted in the center hole of the sleeve. The crystallizer copper plate and the crystallizer back plate are fixedly fitted, and the inner end of the thermocouple fixing hole is arranged toward the crystallizer copper plate. A thermocouple installation hole connected to the thermocouple fixing hole is opened on the crystallizer copper plate. The head of the thermocouple extends out of the sleeve and is inserted into the thermocouple installation hole. The tail of the thermocouple is locked and fixed to the sleeve by a thermocouple locking nut. The head of the thermocouple is fixed to the junction of the crystallizer copper plate and the crystallizer back plate by a positioning block. However, the above-mentioned existing thermocouple installation structure still has the following defects: (1) It is difficult to install the positioning block at the junction of the crystallizer copper plate and the crystallizer back plate in the thermocouple fixing hole, and tools are required; (2) It is necessary to open another thermocouple fixing hole on the crystallizer back plate, which increases the difficulty of processing.

[0014] The implementation method of the crystallizer with temperature measurement function of the utility model is described in detail below:

[0015] Combination Figure 1 and Figure 2A crystallizer with a temperature measurement function comprises a crystallizer copper plate 10, a back plate 20 fitted on the back of the crystallizer copper plate 10, and a temperature measuring component 30 connected between the crystallizer copper plate 10 and the back plate 20, wherein the temperature measuring component 30 comprises a sleeve 31, a thermocouple 32 axially inserted in the center hole of the sleeve 31, and a thermocouple locking nut 33, wherein a sleeve mounting hole 21 is provided on the back plate 20, a sleeve mounting groove 11 connected to the sleeve mounting hole 21 is provided on the crystallizer copper plate 10, the sleeve 31 passes through the sleeve mounting hole 21, and its front end is inserted into and fixed in the sleeve mounting groove 11; the head of the thermocouple 32 extends out of the front end of the sleeve 31 and conflicts with the crystallizer copper plate 10, and the thermocouple locking nut 33 is sleeved on the tail of the thermocouple 32 and is locked and connected with the rear end of the sleeve 31.

[0016] When installing the temperature measuring component 30, first clean the sleeve mounting groove 11 and the sleeve mounting hole 21, then insert the sleeve 31 into the sleeve mounting hole 21 and the sleeve mounting groove 11, then pass the head of the thermocouple 32 through the center hole of the sleeve 31 and make the head of the thermocouple 32 contact the crystallizer copper plate 10, finally, screw and fix the thermocouple locking nut 33 on the rear end of the sleeve 31 to fix the tail of the thermocouple 32.

[0017] The crystallizer with temperature measuring function of the utility model has a simple overall structure, and the sleeve 31 passes through the sleeve mounting hole 21 on the back plate 20 and the front end thereof is inserted into and fixed in the sleeve mounting groove 11 on the crystallizer copper plate 10, that is, the sleeve 31 spans the back plate 20 and the crystallizer copper plate 10. The setting of the sleeve 31 strengthens the connection stability between the back plate 20 and the crystallizer copper plate 10, and reduces the risk of accidental misalignment at the junction of the back plate 20 and the crystallizer copper plate 10. Even if a slight misalignment occurs, the protection of the sleeve 31 can reduce the impact on the thermocouple 32; in addition, there is no need to install a positioning block in the narrow space between the thermocouple 32 and the sleeve, and the installation is simpler.

[0018] Further, such as Figure 2 As shown, the temperature measuring component 30 also includes a spring 34 coaxially sleeved on the thermocouple 32, the front end of the spring 34 is fixedly connected to the thermocouple 32, and the rear end of the spring 34 is in conflict with the thermocouple locking nut 33. When the temperature measuring component 30 is installed, the spring 34 is in a compressed state. The head of the thermocouple 32 is the temperature measuring part, and the spring 34 can provide the thermocouple 32 with a force to press the crystallizer copper plate 10, ensuring that the head of the thermocouple 32 is always pressed against the crystallizer copper plate 10 to avoid poor contact.

[0019] Further, the sleeve 31 is a bolt with a center hole therein, and the outer peripheral wall of the front end of the bolt is threadedly matched with the groove wall of the sleeve installation groove 11, so as to achieve a fixed connection between the sleeve 31 and the crystallizer copper plate 10. Of course, the sleeve and the crystallizer copper plate 10 can also be fixedly connected by fixing methods such as bonding.

[0020] Further, such as Figure 2 As shown, a first sealing ring 36 is provided between the front end face of the sleeve 31 and the inner bottom wall of the sleeve installation groove 11, and the first sealing ring 36 is used to achieve sealing between the front end face of the sleeve 31 and the inner bottom wall of the sleeve installation groove 11 to prevent water vapor from entering and corroding the thermocouple. Furthermore, a first sealing glue layer is also provided in the gap between the front end face of the sleeve 31 and the inner bottom wall of the sleeve installation groove 11 (the first sealing glue layer is formed by applying a layer of sealing glue on the inner bottom wall of the sleeve installation groove 11), and sealing is achieved by the first sealing glue layer. The first sealing ring 36 and the first sealing glue layer are preferably provided at the same time. The first sealing glue layer can achieve or strengthen the fixing effect between the sleeve 31 and the crystallizer copper plate 10, and at the same time, the sealing effect can also be strengthened.

A sleeve locking nut 35 is threadedly fitted on the sleeve 31 in the recessed groove 40, and the outer diameter of the sleeve locking nut 35 is larger than the aperture of the sleeve mounting hole 21. Since the front end of the sleeve 31 is fixedly connected to the crystallizer copper plate 10, the fixed connection between the rear end of the sleeve 31 and the back plate 20 can be achieved by rotating the sleeve locking nut 35 to move it forward. Of course, the fixed connection between the sleeve 31 and the back plate 20 can also be achieved by threaded fitting between the outer peripheral wall of the sleeve 31 and the hole wall of the sleeve mounting hole 21. Furthermore, as Figure 2As shown, an annular gasket 37 is provided between the sleeve locking nut 35 and the inner bottom wall of the sink 40. The gasket 37 is sleeved on the sleeve 31, and a second sealing ring 38 is provided between the front end face of the gasket 37 and the inner bottom wall of the sink 40. The gasket 37 and the second sealing ring 38 can achieve sealing between the front end face of the sleeve locking nut 35 and the inner bottom wall of the sleeve mounting groove 11 to prevent water vapor from entering and corroding the thermocouple. In the specific implementation process, a second sealing layer is also provided in the gap between the front end face of the sleeve locking nut 35 and the inner bottom wall of the sink 40 (a layer of sealant is applied on the inner bottom wall of the sink 40 to form the second sealing layer), and the sealing effect is enhanced by the second sealing layer. The second sealing ring 38 and the second sealing layer are preferably provided at the same time. At the same time, in combination with Figure 1 and Figure 2 The surface of the back plate 20 on the side away from the crystallizer copper plate 10 is also provided with a thermocouple cable routing groove 50 connected to the sink 40. The tail of the thermocouple 32 is usually connected with a compensation wire.
