Description

Technical Field

[0001] The invention relates to the technical field of stainless steel belts, in particular to a novel heat-resistant and wear-resistant stainless steel belt. Background Art

[0002] Stainless steel strip is simply an extension of ultra-thin stainless steel plate. It is a narrow and long steel plate produced to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Stainless steel strips include domestic (imported) stainless steel strips: stainless steel coils, stainless steel spring strips, stainless steel stamping strips, stainless steel precision strips, stainless steel mirror strips, stainless steel cold-rolled strips, stainless steel hot-rolled strips, stainless steel etched strips, stainless steel stretched strips, stainless steel polished strips, stainless steel soft strips, stainless steel hard strips, stainless steel medium-hard strips, etc.

[0003] Stainless steel belts are widely used in many industrial fields, but they also have two shortcomings: first, stainless steel belts are easily deformed after being heated, with poor stability and heat resistance; second, stainless steel belts are easily worn, shortening their service life. The above two problems need to be solved urgently. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present invention provides a novel heat-resistant and wear-resistant stainless steel belt to solve the problem that the stainless steel belt in the prior art has poor heat-resistant and wear-resistant performance.

[0006] (II) Technical solution

[0007] To achieve the above object, the technical solution of the present invention is as follows:

[0008] A new type of heat-resistant and wear-resistant stainless steel belt, characterized in that it includes a central composite belt and wear-resistant composite layers arranged on the upper and lower surfaces of the central composite belt; the central composite belt includes two substrates and a heat sink, the substrate is a stainless steel plate, the heat sink is a copper plate, the heat sink is sandwiched between the two substrates, a receiving cavity is arranged in the substrate, a refrigerant is arranged in the receiving cavity, the refrigerant is liquid at room temperature, and the volume of the refrigerant is smaller than the volume of the receiving cavity; the wear-resistant composite layer is arranged on the surface of the substrate away from the heat sink, and the wear-resistant composite layer is used to protect the substrate from wear.

[0009] Furthermore, the wear-resistant composite layer includes a first protective layer and a second protective layer, wherein the first protective layer is arranged on the surface of the substrate away from the heat sink, and the first protective layer is a polytetrafluoroethylene coating, and the second protective layer is arranged on the surface of the first protective layer away from the substrate, and the second protective layer is a polyurea elastic coating coating.

[0010] Furthermore, a plurality of heat-conducting rods are provided on the surface where the heat sink and the substrate are attached, and the heat-conducting rods are copper rods, and the heat-conducting rods are inserted into the accommodating cavity.

[0011] Furthermore, an end surface of one end of the heat conducting rod inserted into the accommodating cavity is in contact with an inner surface of the accommodating cavity away from the heat dissipation plate.

[0012] Furthermore, a feeding hole is provided on the substrate, the feeding hole is connected to the accommodating cavity, the feeding hole is a threaded hole, a sealing rod is threadedly inserted into the feeding hole, the sealing rod is a threaded rod, and the sealing rod seals the feeding hole.

[0013] Furthermore, a rotation groove is provided on the end surface of the sealing rod away from the accommodating cavity, and the rotation groove is an "I" or "X" groove.

[0014] (III) Beneficial technical effects

[0015] In summary, the present invention includes at least one of the following beneficial technical effects:

[0016] 1. In the present invention, due to the provision of a central composite belt and a wear-resistant composite layer, when the stainless steel belt is heated, the refrigerant in the accommodating cavity will absorb heat and change into a gaseous state, thereby reducing the temperature of the stainless steel belt itself, and preventing the stainless steel belt from being deformed due to excessive temperature. In addition, after the refrigerant absorbs heat and vaporizes, the excess heat can be transferred to the heat sink, and then transferred to the outside through the heat sink, thereby accelerating the heat dissipation of the stainless steel belt itself. The wear-resistant composite layer is provided on the surface of the central composite belt, which can effectively protect the central composite belt from being worn, thereby improving the overall wear resistance of the stainless steel belt. In summary, the stainless steel belt proposed by the present invention has the advantages of good heat resistance and wear resistance;

[0017] 2. Since the wear-resistant composite layer includes a first protective layer and a second protective layer, the first protective layer is arranged on the surface of the substrate away from the heat sink, the first protective layer is a polytetrafluoroethylene coating, and the second protective layer is arranged on the surface of the first protective layer away from the substrate, and the second protective layer is a polyurea elastic coating; wherein the polytetrafluoroethylene coating can not only be used normally in high and low temperature environments, but also has extremely strong resistance to chemicals, acid and alkali corrosion, and stable properties, and the polyurea elastic coating has excellent elastomer physical and mechanical properties, wear resistance, impact resistance, scratch resistance, and good anti-corrosion and waterproof performance, good chemical resistance, good aging resistance, stable and reliable, so the first protective layer and the second protective layer can be used together to effectively protect the central composite belt from wear and corrosion, so as to achieve the purpose of improving the overall anti-corrosion and wear resistance of the stainless steel belt;

[0018] 3. Since a number of heat-conducting rods are arranged on the surface where the heat sink and the substrate are bonded, and the heat-conducting rods are copper rods, and the heat-conducting rods are inserted into the accommodating cavity, the heat absorbed by the refrigerant can be transferred to the heat sink through the heat-conducting rods and finally dissipated to the outside. The heat-conducting rods can effectively increase the rate at which heat is transferred from the refrigerant to the heat sink, thereby improving the heat conduction and heat dissipation effect of the heat sink;

[0019] 4. Since the end surface of the heat-conducting rod inserted into the accommodating cavity is in contact with the inner surface of the accommodating cavity away from the heat dissipation plate, the heat-conducting rod can support the substrate, thereby preventing the substrate from being dented due to the accommodating cavity inside, thereby improving the overall stability of the stainless steel belt;

[0020] 5. Since a feeding hole is provided on the base plate, the feeding hole is connected with the containing cavity, the feeding hole is a threaded hole, and a sealing rod is inserted into the thread in the feeding hole, and the sealing rod is a threaded rod, which blocks the feeding hole. With long-term use, the refrigerant will be consumed. At this time, the user can add refrigerant to the containing cavity through the feeding hole, which is convenient to operate;

[0021] 6. Since the end surface of the sealing rod away from the accommodating cavity is provided with a rotation groove, and the rotation groove is an "I" or "X" groove, it is convenient for the staff to insert the sealing rod into the feeding port or take it out from the feeding port by using tools.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Example:

[0035] Reference Figure 1-3 , a new type of heat-resistant and wear-resistant stainless steel belt disclosed in the present invention, comprising a central composite belt 1 and wear-resistant composite layers 2 arranged on the upper and lower surfaces of the central composite belt 1.

[0036] The central composite belt 1 includes two substrates 3 and a heat sink 4. The substrate 3 is a stainless steel plate, the heat sink 4 is a copper plate, and the heat sink 4 is sandwiched between the two substrates 3. A receiving cavity 5 is provided in the substrate 3. A refrigerant is provided in the receiving cavity 5. The refrigerant is liquid at room temperature, and the volume of the refrigerant is smaller than the volume of the receiving cavity 5. The wear-resistant composite layer 2 is provided on the surface of the substrate 3 away from the heat sink 4, and the wear-resistant composite layer 2 is used to protect the substrate 3 from wear.

[0037] Through the above arrangement, when the stainless steel belt is heated, the refrigerant in the accommodating cavity 5 will absorb heat and change into gas, thereby reducing the temperature of the stainless steel belt itself and preventing the stainless steel belt from being deformed due to excessive temperature. In addition, after the refrigerant absorbs heat and vaporizes, the excess heat can be transferred to the heat sink 4 and transferred to the outside through the heat sink 4, thereby accelerating the heat dissipation of the stainless steel belt itself. The wear-resistant composite layer 2 is arranged on the surface of the central composite belt 1, which can effectively protect the central composite belt 1 from wear, thereby improving the overall wear resistance of the stainless steel belt.

[0038] The wear-resistant composite layer 2 includes a first protective layer 6 and a second protective layer 7. The first protective layer 6 is arranged on the surface of the substrate 3 away from the heat sink 4. The first protective layer 6 is a polytetrafluoroethylene coating. The second protective layer 7 is arranged on the surface of the first protective layer 6 away from the substrate 3. The second protective layer 7 is a polyurea elastic coating. Among them, the polytetrafluoroethylene coating can not only be used normally in high and low temperature environments, but also has extremely strong resistance to chemicals, acid and alkali corrosion, and stable properties; the polyurea elastic coating has excellent elastomer physical and mechanical properties, wear resistance, impact resistance, scratch resistance, and good anti-corrosion and waterproof performance, good chemical resistance, good aging resistance, stable and reliable. Therefore, the first protective layer 6 and the second protective layer 7 can be used together to effectively protect the central composite belt 1 from wear and corrosion, so as to achieve the purpose of improving the overall anti-corrosion and wear resistance of the stainless steel belt.

[0039] Furthermore, a plurality of heat-conducting rods 8 are arranged on the surface where the heat-dissipating plate 4 and the substrate 3 are attached. The heat-conducting rods 8 are evenly distributed in an array on the heat-dissipating plate 4. The heat-conducting rods 8 are copper rods, and the heat-conducting rods 8 are inserted into the accommodating cavity 5. Through the above arrangement, the heat absorbed by the refrigerant can be transferred to the heat-dissipating plate 4 through the heat-conducting rods 8 and finally dissipated to the outside. The heat-conducting rods 8 can effectively increase the rate at which heat is transferred from the refrigerant to the heat-dissipating plate 4, thereby improving the heat conduction and heat dissipation effect of the heat-dissipating plate 4.

[0040] In addition, the end face of one end of the heat-conducting rod 8 inserted into the accommodating cavity 5 is in contact with the inner surface of the accommodating cavity 5 away from the heat dissipation plate 4. Therefore, the heat-conducting rod 8 can play a role in supporting the substrate 3, thereby preventing the surface of the substrate 3 from being concave due to the accommodating cavity 5 provided inside, thereby improving the overall stability of the stainless steel belt.

[0041] Furthermore, a feeding hole 9 is provided on the base plate 3, the feeding hole 9 is connected with the accommodating chamber 5, the feeding hole 9 is a threaded hole, a sealing rod 10 is inserted into the inner thread of the feeding hole 9, and the sealing rod 10 is a threaded rod, and the sealing rod 10 blocks the feeding hole 9. With long-term use, the refrigerant will be consumed. Through the above arrangement, the user can add the refrigerant to the accommodating chamber 5 through the feeding hole 9, which is convenient to operate.

[0042] The end face of the sealing rod 10 away from the accommodating chamber 5 is provided with a rotation groove (not shown in the figure), which is an "I" or "X" groove, so it is convenient for the staff to insert the sealing rod 10 into the feeding port or take it out from the feeding port by tools.

[0043] Working principle of this embodiment: In this embodiment, due to the provision of a central composite belt 1 and a wear-resistant composite layer 2, when the stainless steel belt is heated, the refrigerant in the accommodating cavity 5 will absorb heat and change into a gaseous state, thereby reducing the temperature of the stainless steel belt itself and preventing the stainless steel belt from being deformed due to excessive temperature. In addition, after the refrigerant absorbs heat and vaporizes, excess heat can be transferred to the heat sink 4 and transferred to the outside through the heat sink 4, thereby accelerating the heat dissipation of the stainless steel belt itself. The wear-resistant composite layer 2 is arranged on the surface of the central composite belt 1, which can effectively protect the central composite belt 1 from wear, thereby improving the overall wear resistance of the stainless steel belt. In summary, the stainless steel belt proposed in this embodiment has the advantages of good heat resistance and wear resistance.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
