Description

Heating device for steel strip production Technical Field

[0001] This utility model relates to a heating device for steel strip production, and more particularly to a heating device for steel strip production applied in the field of steel strip production equipment technology. Background Technology

[0002] From the construction industry to the automotive industry, from the machinery field to the electrical appliance field, hot-rolled steel strip is almost ubiquitous. Hot-rolled steel strip refers to strip and plate produced by hot rolling. The production process of hot-rolled steel strip generally includes billet preparation, heating, descaling, rough rolling, finish rolling, cooling, coiling, and finishing.

[0003] Chinese patent CN118875018A discloses a hot rolling apparatus and method for uniformly heated steel strip production, including a frame, two end conveyor roller assemblies, and edge heaters. The end of the frame closer to the roughing mill is the input end, and the end closer to the finishing mill is the output end. The two end conveyor roller assemblies are respectively located at the input and output ends of the frame. Two edge heaters are located between the two end conveyor roller assemblies, with the two edge heaters facing each other on opposite sides of the frame. The edge heaters have a U-shaped structure, with the U-shaped openings of the two edge heaters facing each other. A central conveyor roller assembly for conveying the steel strip is located between the two edge heaters. An adjusting frame is hinged to the side of the edge heater opposite its U-shaped opening, and a first cylinder is installed between the adjusting frame and the frame. By heating and maintaining the temperature of the edge of the steel strip with the edge heaters, the temperature difference between the middle and edge of the steel strip is reduced, achieving uniform heating of the steel strip.

[0004] Existing steel strip heating devices suffer from waste of resources because the inlet and outlet openings are too large, causing heat and waste gas generated during processing to escape from the heating equipment. Summary of the Invention

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that, in the use of existing steel strip heating devices, the inlet and outlet openings are too large, causing heat inside the heating equipment and waste gas generated during processing to escape, resulting in resource waste.

[0006] To solve the above problems, this utility model provides a heating device for steel strip production, including a base, a heating device fixedly connected to the top of the base, conveyor belts installed on both sides of the heating device at the top of the base, a protective cover detachably connected to the top of the base, grooves symmetrically carved on the top of the base, a locking block fixedly connected to the bottom of the protective cover and engaging with the groove, an air hole opened at the top of the protective cover, an air extraction pipe threaded into the air hole, and an air pump connected to the end of the air extraction pipe away from the air hole, an opening opened at the end of the protective cover away from the heating device, a magnetic plate fixedly connected to the side of the protective cover directly above the opening, a baffle brush adhered to the magnetic plate, and a storage box with casters at the bottom placed directly below the baffle brush.

[0007] In the above-mentioned heating device, by setting up a protective cover, heat and waste gas can be collected during the heating treatment of steel strip, and then the waste gas can be extracted by an air pump, while at the same time achieving the effect of heat retention and preventing heat loss.

[0008] As a further improvement to this application, a side opening is provided at the side end of the protective cover, and an observation window is rotatably connected to the side wall of the side opening via a hinge.

[0009] As a further improvement to this application, a sealing ring is fixedly connected to one end of the observation window near the side opening, and the observation window is made of transparent material.

[0010] As a further improvement of this application, the heating device has symmetrically chiseled discharge ports at both ends, and baffles are slidably connected to the inner walls of the discharge ports.

[0011] As another improvement of this application, the top of the heating device is chiseled with a sliding opening corresponding to the baffle, a pressure plate is inserted into the sliding opening, and the bottom end of the pressure plate is fixedly connected to the baffle. A measuring scale is engraved on the pressure plate.

[0012] As a further improvement to this application, the inner wall of the discharge port is symmetrically carved with grooves, and magnetic blocks corresponding to the grooves are symmetrically fixedly connected to both ends of the baffle, and the magnetic blocks are engaged with the grooves.

[0013] As a further improvement to this application, the inner wall of the slide is made of magnetic material, and the magnetic block attracts the inner wall of the slide.

[0014] In summary, the steel strip enters the heating equipment through the discharge port at the back for heating and processing. After heating, it is conveyed onto the conveyor belt through the discharge port at the front, thus transporting the heated steel strip. The heat generated during processing leaks from the discharge port into the protective cover, and the exhaust gas generated during processing also leaks out. At this time, an air pump can be turned on to extract the exhaust gas leaking into the protective cover through the extraction pipe for purification treatment, preventing the exhaust gas from leaking into the air. In addition, the air pipe located at the top inside the protective cover is equipped with an upward-opening funnel-shaped air inlet, which can reduce the amount of dust drawn in from the bottom. The possibility of heat treatment is also present. When the heat-treated steel belt is transported by the conveyor belt, as the steel belt moves out of the protective cover from the opening, it is scraped by the baffle brush, which can sweep the debris carried during the heat treatment onto the conveyor belt. As the conveyor belt rotates, the debris falls into the collection box for collection and treatment. The baffle brush can also block the opening to a certain extent, reducing the outlet and reducing heat loss. By setting up the protective cover, heat and waste gas can be collected during the heat treatment of the steel belt. Then, the waste gas can be extracted by the air pump, which also achieves the effect of heat retention and avoids heat loss. Attached Figure Description

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figure 1-5 shows a heating device for steel strip production, including a base 1, a heating device 2 fixedly connected to the top of the base 1, conveyor belts 6 installed on both sides of the top of the base 1 at the heating device 2, a protective cover 3 detachably connected to the top of the base 1, slots 11 symmetrically carved on the top of the base 1, a locking block 19 fixedly connected to the bottom of the protective cover 3 and engaging with the slot 11, an air hole 14 opened at the top of the protective cover 3, an air extraction pipe 4 internally threaded to the air hole 14, and an air pump connected to the end of the air extraction pipe 4 away from the air hole 14, an opening 16 opened at the end of the protective cover 3 away from the heating device 2, a magnetic plate 15 fixedly connected to the side of the protective cover 3 directly above the opening 16, a baffle brush 5 adhered to the magnetic plate 15, and a storage box 21 with casters at the bottom placed directly below the baffle brush 5.

[0027] Working principle: The steel strip enters the heating equipment 2 through the discharge port 12 on the back for heating and processing. After heating, it is conveyed from the discharge port 12 on the front to the conveyor belt 6 for transport. The heat generated during processing leaks from the discharge port 12 into the protective cover 3, and the exhaust gas generated during processing also leaks out. At this time, the air pump can be turned on to extract the exhaust gas leaking into the protective cover 3 through the air extraction pipe 4 for purification treatment, preventing the exhaust gas from leaking into the air. The air pipe located at the top inside the protective cover 3 is equipped with a funnel-shaped inlet with an upward opening. The air vent reduces the possibility of dust being sucked in from the bottom. At the same time, when the heat-treated steel belt is transported by the conveyor belt 6, when the steel belt moves out of the protective cover 3 through the opening 16, it is scraped by the baffle 5, which can sweep the debris carried during the heat treatment onto the conveyor belt 6. After the steel belt is removed by the circulating rotation of the conveyor belt 6, the debris that falls on the conveyor belt 6 falls into the collection box 21 from the gap between the bottom of the baffle 5 and the conveyor belt 6 for collection and treatment. The baffle 5 can also block the opening 16 to a certain extent, reduce the outlet, and reduce heat loss.

[0028] By setting up a protective cover 3, heat and waste gas can be collected during the heating treatment of the steel strip. The waste gas can then be extracted by an air pump, which also achieves the effect of heat retention and prevents heat loss.

[0029] Second implementation method:

[0030] Figures 2-3 and 6-7 show that the protective cover 3 has a side opening 17 on its side end. The side wall of the side opening 17 is rotatably connected to an observation window 8 via a hinge. A sealing ring 18 is fixedly connected to one end of the observation window 8 near the side opening 17. The observation window 8 is made of transparent material. The heating device 2 has symmetrically carved discharge ports 12 at both ends. A baffle 10 is slidably connected to the inner wall of the discharge port 12. The top of the heating device 2 has a sliding opening 9 corresponding to the baffle 10. A pressure plate 7 is inserted into the sliding opening 9, and the bottom end of the pressure plate 7 is fixedly connected to the baffle 10. A measuring ruler 20 is engraved on the pressure plate 7. The inner wall of the discharge port 12 has symmetrically carved grooves 13. The two ends of the baffle 10 are symmetrically fixedly connected to magnetic blocks 22 corresponding to the grooves 13. The magnetic blocks 22 are engaged with the grooves 13. The inner wall of the grooves 13 is made of magnetic material, and the magnetic blocks 22 and the inner wall of the grooves 13 attract each other.

[0031] Working principle: Before heating the steel strip, the gap between the baffle 10 and the discharge port 12 can be adjusted by sliding the pressure plate 7 up and down according to the thickness of the steel strip. The pressure plate 7 is equipped with a measuring ruler 20, which can be adjusted precisely. The baffle 10 is magnetically fixed to the inner wall of the slide groove 13 by the magnetic block 22. During the processing of the steel strip, the internal condition can be observed through the observation window 8 to avoid malfunctions and to detect and deal with them in time.

[0032] The baffle 10 is precisely adjusted according to the thickness of the steel strip by the pressure plate 7, thereby controlling the gap between the baffle 10 and the discharge port 12 and reducing heat loss in the heating equipment 2.

[0033] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
