Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, in particular to a continuous casting billet conveying device. Background Art

[0002] A continuous casting billet is a plate-shaped, rectangular or circular billet formed after molten steel is processed through components such as a tundish and a mold during the steelmaking process. After the continuous casting billet is obtained, it needs to be conveyed, cooled, and sampled for inspection. For unqualified continuous casting billets, remelting and processing are required.

[0003] During the conveying process of the continuous casting billet, due to its high surface temperature, directly conveying it to the aerosol cooling section will cause its surface to cool rapidly, while the core temperature cannot be transferred quickly, resulting in local stress concentration and cracks on the surface, thus affecting the overall quality of the continuous casting billet. To address this problem, in addition to adjusting the raw material components or processing parameters, surface grinding, flame treatment, etc. can also be carried out. However, these treatment methods are not easy to adjust on the one hand, and on the other hand, they are post-remedial measures after abnormalities occur. Summary of the Utility Model

[0004] The utility model provides a continuous casting billet conveying device for the above problems.

[0005] The technical solution adopted is that the continuous casting billet conveying device includes a crystallizer blanking device, a blowing cooler, and a horizontal conveyor;

[0006] The discharge end of the crystallizer blanking device conveys the continuous casting billet to the feed end of the blowing cooler;

[0007] A air supply mechanism and a continuous casting billet pushing mechanism are arranged in the blowing cooler;

[0008] The horizontal conveyor is arranged at the discharge end of the blowing cooler, and the horizontal conveyor conveys the continuous casting billet to the continuous casting billet aerosol cooling device.

[0009] Optionally, a guiding wheel is arranged at the discharge end of the crystallizer blanking device, and the guiding wheel can contact the lower part of the continuous casting billet.

[0010] Optionally, a fixing seat is arranged at the discharge end of the crystallizer blanking device, an elastic movable platform is installed on the fixing seat, the guiding wheel is installed on the elastic movable platform, and the guiding wheel can move vertically on the elastic movable platform.

[0011] Optionally, the air supply mechanism includes an induced draft fan arranged at the top of the blowing cooler, and the induced draft fan can discharge the air introduced from the air inlet end and the air outlet end of the blowing cooler.

[0012] Optionally, the continuous casting billet pushing mechanism includes a first pushing wheel disposed at the feeding end of the blowing cooler and a second pushing wheel disposed at the discharging end of the blowing cooler, and both the first pushing wheel and the second pushing wheel can contact the upper part of the continuous casting billet.

[0013] Optionally, a first mounting seat is provided at the feeding end of the blowing cooler, a first driving motor is provided on the first mounting seat, the first pushing wheel is disposed below the first mounting seat, and the first driving motor can drive the first pushing wheel to rotate;

[0014] A second mounting seat is provided at the discharging end of the blowing cooler, a second driving motor is provided on the second mounting seat, the second pushing wheel is disposed below the second mounting seat, and the second driving motor can drive the second pushing wheel to rotate.

[0015] Optionally, auxiliary pushing sections are arranged at intervals on the horizontal conveyor, and auxiliary pushing wheels are arranged in the auxiliary pushing sections.

[0016] The advantages of the present utility model include:

[0017] 1. By arranging a blowing cooler and a horizontal conveyor behind the discharging end of the original crystallizing blanking device, the former can relatively gently reduce the temperature of the outer billet shell of the continuous casting billet through flowing air, so that the temperature difference between the outer billet shell and the inner core is not too large. The latter further cools down in an open-air exposed environment after relatively gentle cooling, facilitating subsequent aerosol cooling treatment.

Detailed Embodiment

[0022] The following specific examples illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0023] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present utility model in a schematic manner. Therefore, only the components related to the present utility model are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation can be arbitrarily changed, and the layout type of the components may also be more complex.

[0024] As Figure 1 and Figure 2 shown, the continuous casting billet conveying device includes a crystallization blanking device 1, a blowing cooler 2, and a horizontal conveyor 3;

[0025] The discharge end of the crystallization blanking device 1 conveys the continuous casting billet 4 to the feed end of the blowing cooler 2;

[0026] A air supply mechanism and a continuous casting billet pushing mechanism are arranged in the blowing cooler 2;

[0027] The horizontal conveyor 3 is arranged at the discharge end of the blowing cooler 2, and the horizontal conveyor 3 conveys the continuous casting billet 4 to the continuous casting billet aerosol cooling device.

[0028] The purpose of such a design is that by arranging a blowing cooler and a horizontal conveyor behind the discharge end of the original crystallization blanking device, the former can relatively gently reduce the temperature of the outer billet shell of the continuous casting billet through flowing air, so that the temperature difference between the outer billet shell and the inner core is not too large. The latter further cools down in an open and exposed environment after relatively gentle cooling, facilitating subsequent aerosol cooling treatment.

[0029] In this embodiment, a guiding mechanism is provided. A guiding wheel 6 is arranged at the discharge end of the crystallization blanking device 1. The guiding wheel 6 can contact the lower part of the continuous casting billet 4. A fixed seat 5 is arranged at the discharge end of the crystallization blanking device 1. An elastic movable platform is installed on the fixed seat 5. The guiding wheel 6 is installed on the elastic movable platform, and the guiding wheel 6 can vertically move on the elastic movable platform.

[0030] The purpose of such a design is that since the uncooled continuous casting billet has large plasticity, the arranged guiding wheel can connect the crystallization blanking device and the blowing cooler to avoid deformation during the entire conveying stage.

[0031] It should be noted that regarding the elastic movable table, it is an existing design which generally includes a table body and springs arranged under the table body. When bearing weight, the table body will squeeze the springs downward, and when the weight becomes lighter or disappears, the springs will reset.

[0032] In this embodiment, the air supply mechanism includes an induced draft fan 14 arranged on the top of the blowing cooler 2, and the induced draft fan 14 can discharge the air introduced from the air inlet end and the air outlet end of the blowing cooler 2.

[0033] The purpose of such design is that since the feeding end and the discharging end of the blowing cooler are not completely sealed, external gas can enter the blowing cooler through the gap and then be discharged through the induced draft fan. Of course, the air induction direction of the induced draft fan can be to introduce gas or to discharge gas, and on-site workers can adjust it according to the actual situation.

[0034] In this embodiment, the continuous casting billet pushing mechanism includes a first pushing wheel 7 arranged at the feeding end of the blowing cooler 2 and a second pushing wheel 8 arranged at the discharging end of the blowing cooler 2, and both the first pushing wheel 7 and the second pushing wheel 8 can contact the upper part of the continuous casting billet 4. A first mounting seat 9 is arranged at the feeding end of the blowing cooler 2, a first driving motor 11 is arranged on the first mounting seat 9, the first pushing wheel 7 is arranged below the first mounting seat 9, and the first driving motor 11 can drive the first pushing wheel 7 to rotate;

[0035] A second mounting seat 10 is arranged at the discharging end of the blowing cooler 2, a second driving motor 12 is arranged on the second mounting seat 10, the second pushing wheel 8 is arranged below the second mounting seat 10, and the second driving motor 12 can drive the second pushing wheel 8 to rotate.

[0036] The purpose of such design is that by arranging the first pushing wheel and the second pushing wheel, the continuous casting billet can be pushed to move in the blowing cooler, providing it with certain power.

[0037] In this embodiment, auxiliary pushing sections 15 are arranged at intervals on the horizontal conveyor 3, and auxiliary pushing wheels are arranged in the auxiliary pushing sections 15.

[0038] It should be noted that since the temperature of the entire working conveying area is relatively high, water tanks are usually laid under the crystallizing blanking device 1, the blowing cooler 2 and the horizontal conveyor 3 to reduce the temperature of this area. The horizontal conveyor is arranged above the water tank, and grid-shaped partition plates are usually laid for support and ventilation. The arranged auxiliary pushing sections are mainly used for conveying longer continuous casting billets to avoid accumulation due to their excessive length. The auxiliary pushing sections usually also consist of a pushing motor and a pushing wheel, which push the continuous casting billet from above and / or below, and the design of the first pushing wheel or the second pushing wheel can be referred to.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
