[0002] With the development of technology and the increasingly fierce competition in the steel market, the requirements for the performance of steel products are getting higher and higher. High-performance steel requires scientific design on the one hand and precise composition control on the other hand. To achieve precise control of the steel composition and stable control of the quality, the RH vacuum refining process is an indispensable smelting equipment at present. During the refining process, a certain amount of cold steel will be generated in the middle and lower parts of the vacuum tank. If the cold steel is not processed in time, the whole cold steel will fall off, resulting in abnormal steel liquid composition, seriously affecting the production rhythm matching in the steelmaking process. At the same time, the falling of cold steel nodules will also affect the cleanliness and temperature of the steel liquid.

[0003] Through the operation of melting cold steel, the cold steel is melted into the cold steel bucket, and the cold steel is transferred to the designated area through the cold steel bucket. In the related technology, the service life of the cold steel bucket is relatively short. Utility Model Content

[0033] With the development of technology and the increasingly fierce competition in the steel market, the requirements for the performance of steel products are getting higher and higher. High-performance steel requires scientific design on the one hand and precise composition control on the other hand. To achieve precise control of the steel composition and stable control of the quality, RH vacuum refining treatment is an indispensable smelting equipment at present. During the refining process, a certain amount of cold steel will be generated in the middle and lower parts of the vacuum tank. If the cold steel is not processed in time, it will cause the overall shedding of the cold steel, resulting in abnormal steel liquid composition, seriously affecting the production rhythm matching during the steelmaking process. At the same time, the falling of the cold steel nodules will also affect the cleanliness and temperature of the steel liquid.

[0034] The cold steel is melted into the cold steel bucket through the operation of melting cold steel, and the cold steel is transferred to the designated area through the cold steel bucket.

[0035] In actual production, the applicant found that the temperature of the cold steel has little effect on the peripheral wall of the cold steel bucket, and problems such as deformation and cracking that affect the service life are not likely to occur on the peripheral wall of the cold steel bucket. The temperature of the bottom wall of the cold steel bucket is greatly affected by the temperature of the cold steel. Compared with the peripheral wall, the bottom wall of the cold steel bucket is more likely to deform and crack after being heated for a long time. Moreover, the long-term heating of the bottom wall of the cold steel bucket accelerates the corrosion and oxidation of the bottom wall of the cold steel bucket, and the bottom wall of the cold steel bucket is extremely likely to become thinner and unable to continue to support the cold steel, resulting in the cold steel bucket being unable to continue to be used, and thus the service life of the cold steel bucket is relatively short.

[0036] Therefore, in the related art, there is a technical problem that the service life of the cold steel bucket is relatively short. The embodiments of the present application provide a cold steel bucket, which can at least solve the technical problem of the relatively short service life of the cold steel bucket to a certain extent.

[0037] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0038] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown in the figures, the cold steel bucket 100 includes a cold steel bucket body 110, a plurality of anchor hooks 120, a refractory layer 130, and a plurality of lifting lugs 140.

[0039] The cold steel bucket body 110 has a steel storage tank 110a for storing cold steel; a plurality of anchor hooks 120 are arranged at intervals on the bottom wall of the steel storage tank 110a and are fixedly connected to the bottom wall of the steel storage tank 110a; the refractory layer 130 is arranged on the bottom wall of the steel storage tank 110a, and the anchor hooks 120 are located inside the refractory layer 130; a plurality of lifting lugs 140 are all located outside the steel storage tank 110a and are fixedly connected to the cold steel bucket body 110.

[0040] During use, the lifting device is connected to the lifting lug 140, and the cold steel bucket 100 is placed below the cold steel discharge port through the lifting device to receive the cold steel discharged from the cold steel discharge port, and the cold steel falls into the steel storage tank 110a. Since the present application is provided with a refractory layer 130 on the bottom wall of the steel storage tank 110a, the refractory layer 130 can isolate the heat released by the cold steel to a certain extent, so that the bottom wall of the steel storage tank 110a is less affected by the high temperature of the cold steel, and thus the bottom wall of the steel storage tank 110a is not likely to deform, crack, corrode, and oxidize, etc., improving the service life of the bottom wall of the steel storage tank 110a, and thereby extending the service life of the cold steel bucket 100.

[0041] The cold steel bucket body 110 is usually made of metal. The bonding property between the refractory layer 130 and the metal is poor. The function of the anchor hook 120 is to reinforce and tie the refractory layer 130, so that the refractory layer 130 can adhere more firmly to the bottom wall of the molten steel storage tank 110a, and the refractory layer 130 can form an integral body with the cold steel bucket body 110, which helps to reduce the probability of local or overall shedding of the refractory layer 130, and further extends the service life of the cold steel bucket 100. The structure of the anchor hook 120 is diverse and can be Y-shaped, L-shaped, etc., which is not limited in this application. The user can manufacture the anchor hook 120 in this application by using the existing technology.

[0042] The lifting lug 140 is arranged outside the molten steel storage tank 110a, which can facilitate the connection between the lifting lug 140 and the hook of the lifting device, and is convenient for the lifting operation.

[0043] The number of the lifting lugs 140 is not limited in this application and can be two, three, four, etc. Multiple lifting lugs 140 can be symmetrically arranged on the cold steel bucket body 110 to ensure the balance of the cold steel bucket during lifting and facilitate the lifting device to lift.

[0044] The material of the refractory layer 130 is diverse. In some embodiments, the material used for the refractory layer 130 is high-strength low-cement castable, and the refractoriness is ≥1760 °C.

[0045] After the molten steel storage tank 110a of the cold steel bucket is filled with molten steel, the hook of the lifting device can be connected to the lifting lug 140, the hook is lifted, and the movement direction of the lifting device is controlled to lift the cold steel bucket 100 to the position where the molten steel is unloaded. When the cold steel bucket is lifted to the designated position, some hooks can be separated from the lifting lug 140, and some hooks are kept connected to the lifting lug 140, and the hook is lifted to realize the tipping operation, so that the molten steel in the cold steel bucket 100 drops.

[0046] As Figure 6 shown, in some embodiments, the anchor hook 120 is in a w shape. The lower end of the anchor hook 120 is fixedly connected to the bottom wall of the molten steel storage tank 110a. In some embodiments, both the anchor hook 120 and the cold steel bucket body 110 are made of metal, and the lower end of the anchor hook 120 is fixedly connected to the bottom wall of the molten steel storage tank 110a by welding.

[0047] As Figure 4 shown, in some embodiments, multiple anchor hooks 120 are arranged in an array. In each row, two adjacent anchor hooks 120 are vertically arranged, and in each column, two adjacent anchor hooks 120 are also vertically arranged.

[0048] That is to say, in each row and each column, the anchor hooks 120 are arranged in the order of horizontal - vertical - horizontal - vertical... After such a design, multiple anchor hooks 120 can provide acting forces on various regions of the refractory layer 130, and provide acting forces in different directions, which helps to fix the refractory layer 130 more firmly on the anchor hooks 120, and adhere more firmly to the bottom wall of the steel storage tank 110a, further reducing the risk of local or overall detachment of the refractory layer 130, and extending the service life of the cold steel bucket 100.

[0049] In some embodiments, the cold steel bucket body 110 includes a bottom plate 111 and a plurality of side plates 112 that are sequentially arranged around the circumference of the bottom plate 111 and connected end to end. The bottom plate 111 is fixedly connected to the side plates 112, and the bottom plate 111 and the plurality of side plates 112 enclose to form a steel storage tank 110a; the anchor hooks 120 are fixedly connected to the bottom plate 111, and the refractory layer 130 is arranged on the bottom plate 111.

[0050] The number of the side plates 112 is not limited in this application. The number of the side plates 112 should be greater than or equal to three to ensure that the side plates 112 and the bottom plate 111 can successfully enclose the steel storage tank 110a. The number of the side plates 112 can be four, five, six, etc.

[0051] The plurality of side plates 112 are sequentially arranged around the circumference of the bottom plate 111 and connected end to end. The side plates 112 and the bottom plate 111 also need to be fixedly connected. The plurality of side plates 112 are sequentially arranged and connected end to end to form an annular structure. Then, under the action of the bottom plate 111, the steel storage tank 110a is enclosed. The upper end surface of the bottom plate 111 is the bottom wall of the steel storage tank 110a. Therefore, the refractory layer 130 and the anchor hooks 120 are arranged on the bottom plate 111 and located on the upper surface of the bottom plate 111.

[0052] In some embodiments, the side plates 112 are hermetically connected between the side plates 112 and between the side plates 112 and the bottom plate 111 to prevent small pieces of cold steel, steel slag, steel chips, etc. in the steel storage tank 110a from falling out through the gaps between the side plates 112 or the gaps between the side plates 112 and the bottom plate 111, endangering the safety of the operators, and improving the safety performance of the cold steel bucket 100 of this application.

[0053] In some embodiments, the side plates 112 are fully welded by welding between the side plates 112 and between the side plates 112 and the bottom plate 111, realizing a hermetic and fixed connection between the side plates 112 and a hermetic and fixed connection between the side plates 112 and the bottom plate 111.

[0054] In some embodiments, the bottom plate 111 of the cold steel bucket is rectangular, and the side plates 112 include two first side plates 1121 and two second side plates 1122. The two first side plates 1121 are arranged oppositely and are respectively fixedly connected to two short sides of the bottom plate 111. The two second side plates 1122 are arranged oppositely and are respectively fixedly connected to two long sides of the bottom plate 111. The lifting lugs 140 are arranged on the first side plate 1121 and / or the second side plate 1122.

[0055] In these embodiments, there are four side plates 112, two of which are the first side plates 1121 and the other two are the second side plates 1122. The two first side plates 1121 are arranged oppositely and are respectively located at two short sides of the bottom plate 111. The lower ends of the first side plates 1121 are fixedly connected to the short sides of the bottom plate 111. The two second side plates 1122 are arranged oppositely and are respectively located at two long sides of the bottom plate 111. The lower ends of the second side plates 1122 are fixedly connected to the long sides of the bottom plate 111. The adjacent first side plate 1121 and the second side plate 1122 are also fixedly connected.

[0056] The lifting lugs 140 can be arranged on the first side plate 1121, or on the second side plate 1122, or the lifting lugs 140 are arranged on both the first side plate 1121 and the second side plate 1122, which is not limited in this application.

[0057] In some embodiments, four lifting lugs 140 are provided. The four lifting lugs 140 are respectively installed on the two first side plates 1121. The lifting lugs 140 are installed on the side of the first side plate 1121 close to the second side plate 1122, and the lifting lugs 140 are arranged on the side of the first side plate 1121 away from the bottom plate 111.

[0058] After such a design, two lifting lugs 140 are respectively arranged on the two first side plates 1121. The two lifting lugs 140 on the first side plate 1121 are respectively installed on both sides of the first side plate 1121 close to the two second side plates 1122. That is to say, one of the lifting lugs 140 is installed on the side of the first side plate 1121 close to one of the second side plates 1122, and the other lifting lug 140 is installed on the side of the first side plate 1121 close to the other second side plate 1122. As Figure 2 shown, the two lifting lugs 140 on the first side plate 1121 are both arranged on the upper side of the first side plate 1121 and are respectively installed on the left side and the right side of the first side plate 1121 to ensure the balance of the cold steel bucket during the lifting process.

[0059] During lifting, the lifting device is simultaneously connected to the four lifting lugs 140 to ensure the balance of the cold steel bucket during the lifting process. The lifting lugs 140 are arranged on the side of the first side plate 1121 away from the bottom plate 111 to facilitate the operator to connect the lifting device and the lifting lugs 140.

[0060] In some embodiments, the cross-section of the steel storage tank 110a gradually increases from one side near the bottom of the tank to the other side far from the bottom of the steel storage tank 110a.

[0061] After such a design, the steel storage tank 110a has a shape that is larger at the top and smaller at the bottom. The size of the tank opening of the steel storage tank 110a is relatively large, which is convenient for receiving cold steel. And after such a design, the side wall of the steel storage tank 110a is in an inclined shape, that is, the first side plate 1121 and the second side plate 1122 are in an inclined shape. When pouring out the cold steel in the steel storage tank 110a, the cold steel can fall more quickly along the inclined side wall, which helps to reduce the residue of cold steel and ensure that all the cold steel is poured out.

[0062] As Figure 4 shown, in some embodiments, both the first side plate 1121 and the second side plate 1122 are in the shape of an isosceles trapezoid. The heights of the first side plate 1121 and the second side plate 1122 are the same. The upper base of the first side plate 1121 has the same length as the short side of the bottom plate 111, and the upper base of the first side plate 1121 is welded to the short side of the bottom plate 111. The upper base of the second side plate 1122 has the same length as the long side of the bottom plate 111, and the upper base of the second side plate 1122 is welded to the long side of the bottom plate 111. Between the adjacent first side plate 1121 and the second side plate 1122, the waists of the first side plate 1121 and the second side plate 1122 are welded together to form the cold steel hopper body 110 in this way. After such a design, the cross-section of the steel storage tank 110a gradually increases from one side near the bottom of the tank to the other side far from the bottom of the steel storage tank 110a.

[0063] As Figure 1 and Figure 5 shown, in order to facilitate pouring out the cold steel in the cold steel hopper, in some embodiments, the cold steel hopper 100 further includes a turning lifting lug 150. The turning lifting lug 150 is arranged on the first side plate 1121 or the second side plate 1122, and the turning lifting lug 150 is arranged close to the bottom plate 111.

[0064] The number of the turning lifting lugs 150 is not limited in this application, and it can be set to one, two, three, etc. The turning lifting lug 150 can be arranged on the first side plate 1121 or on the second side plate 1122. After the turning lifting lug 150 is arranged close to the bottom plate 111, when the lifting device is connected to the turning lifting lug 150 and the cold steel hopper 100 is turned, after the cold steel hopper 100 rotates around the turning lifting lug 150, the opening of the cold steel hopper 100 will face downward, which helps to completely pour out the cold steel in the cold steel hopper.

[0065] In some embodiments, the turning lifting lug 150 is arranged on the first side plate 1121, and the length direction of the turning lifting lug 150 is perpendicular to the first side plate 1121.

[0066] After such a design, the tipping lug 150 inclines downward, and the lifting holes on the tipping lug 150 can be closer to the bottom plate 111. When tipping the cold steel bucket, the opening of the cold steel bucket is more likely to face downward, which helps to completely pour out the cold steel in the cold steel bucket.

[0067] As Figure 2 shown, in some embodiments, there are two tipping lugs 150. The two tipping lugs 150 are arranged on the same first side plate 1121, and the two tipping lugs 150 are arranged at the same height and are respectively located on both sides of the first side plate 1121 close to the two second side plates 1122. That is, as Figure 2 shown, the two tipping lugs 150 are both located on the lower side of the first side plate 1121 and are respectively installed on the left and right sides of the first side plate 1121.

[0068] As Figure 2 shown, in some embodiments, the cold steel bucket body 110 further includes a plurality of support plates 113. The plurality of support plates 113 are arranged at intervals below the bottom plate 111 and are fixedly connected to the bottom plate 111.

[0069] The support plates 113 can be two, three, etc. The support plates 113 are located below the bottom plate 111 and are fixedly connected to the bottom plate 111, playing a role in supporting the bottom plate 111. The design of the support plates 113 helps to enhance the overall stability of the cold steel bucket 100 and helps the cold steel bucket 100 to adapt to different ground conditions.

[0070] In some embodiments, there are two support plates 113, and both of the two support plates 113 are parallel to the long side of the bottom plate 111.

[0071] In the description of this specification, the description referring to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application.
