Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, and in particular to an explosion-proof baffle. Background Technology

[0002] Statistics show that approximately 20% of the production of 1 ton of stainless steel generates slag, with a metal content of about 10%. Stainless steel slag contains valuable rare heavy metals such as nickel and chromium. Improper handling can cause serious environmental pollution. Therefore, recycling the metals from stainless steel slag and realizing the resource recycling of stainless steel slag is an important issue facing steel companies.

[0003] When producing stainless steel using an AOD furnace (argon-oxygen refining furnace), the resulting slag is poured into a ladle, transported to a water quenching station for quenching, and then lifted by an elevator for recycling. During this process, the high-temperature slag can explode and splash when discharged into the quenching tank. Existing single-piece explosion-proof baffles suffer from uneven stress distribution and are prone to deformation and cracking. Damage to these baffles necessitates complete replacement, resulting in high maintenance costs and prolonged downtime. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an explosion-proof baffle for water quenching of steel slag that is easy to maintain and has a good slag-blocking effect.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing an explosion-proof baffle for slag interception in a slag quenching pool for steel slag granulation. The explosion-proof baffle is disposed on the side of the slag quenching pool and includes a support and hollow explosion-proof blocks. The support includes horizontal ribs, and multiple explosion-proof blocks are sequentially attached to and suspended on the horizontal ribs. The space inside the explosion-proof blocks is filled with fluid at a volume ratio of 0.3-0.6.

[0006] The beneficial effects of this utility model are as follows: The explosion-proof baffle of this utility model, by setting a segmented explosion-proof block structure, and each explosion-proof block contains fluid, each explosion-proof block is independently shaken and subjected to force, and the explosion-proof blocks will shake asynchronously, so that the force of the explosion-proof blocks acting on the support will cancel each other out, avoiding the problems of existing whole explosion-proof baffles being easily damaged by the overall force and difficult to repair and replace, and also improving the durability, safety and economy of the explosion-proof baffle.

[0011] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0012] This utility model provides an explosion-proof baffle for slag interception in a slag quenching pool for steel slag granulation. The explosion-proof baffle is disposed on the side of the slag quenching pool and includes a support and hollow explosion-proof blocks. The support includes horizontal ribs, and multiple explosion-proof blocks are sequentially attached to and suspended on the horizontal ribs. The space inside the explosion-proof blocks is filled with fluid at a volume ratio of 0.3-0.6.

[0013] The advantages of this invention are as follows: The explosion-proof baffle of this invention, through the segmented explosion-proof block structure and the fluid contained in each explosion-proof block, is independently shaken and subjected to force. The force exerted by the explosion-proof blocks on the support will cancel each other out, avoiding the problems of easy damage and difficult maintenance and replacement of the existing whole explosion-proof baffle under the force, thus improving the durability, safety and economy of the explosion-proof baffle.

[0014] Furthermore, in the aforementioned explosion-proof baffle, the top of the explosion-proof block is provided with multiple hanging holes, and the explosion-proof block is suspended on the horizontal rib by lines passing through the hanging holes.

[0015] As described above, hanging by lines is an economical and practical way to fix explosion-proof blocks.

[0016] Furthermore, in the aforementioned explosion-proof baffle, the top of the explosion-proof block is provided with two hanging holes, and a chain is installed through each hanging hole to suspend the explosion-proof block on the horizontal rib.

[0017] Furthermore, in the aforementioned explosion-proof baffle, the fluid is water.

[0018] Furthermore, in the aforementioned explosion-proof baffle, the fluid is sand.

[0019] Furthermore, in the aforementioned explosion-proof baffle, the explosion-proof block is made of heat-resistant ductile iron or high-temperature alloy steel.

[0020] As described above, heat-resistant ductile iron has good high-temperature resistance, strong resistance to high-temperature deformation, and is easy to clean as steel slag does not easily adhere to it.

[0021] Furthermore, in the aforementioned explosion-proof baffle, the explosion-proof block is a cuboid.

[0022] Furthermore, in the aforementioned explosion-proof baffle, the lines are stainless steel chains.

[0023] Furthermore, in the aforementioned explosion-proof baffle, the support frame is constructed from H-beams.

[0024] Furthermore, in the aforementioned explosion-proof baffle, the space inside the explosion-proof block is filled with half sand.

[0025] As can be seen from the above description, the explosion-proof block is best when it is filled with half sand.

[0026] Example 1

[0027] Please refer to Figure 1 and Figure 2 As shown, an explosion-proof baffle is used for slag interception in a slag quenching pool for steel slag granulation. The explosion-proof baffle is installed on the side of the slag quenching pool. The explosion-proof baffle includes a support 2 and a hollow explosion-proof block 1. The support 2 includes a horizontal rib, and a plurality of explosion-proof blocks 1 are sequentially attached to and suspended on the horizontal rib. The space inside the explosion-proof block is filled with half sand.

[0028] The explosion-proof block 1 has two hanging holes at its top, and a chain is installed through each hanging hole to suspend the explosion-proof block on the horizontal rib. The explosion-proof block is made of heat-resistant ductile iron or high-temperature alloy steel.

[0029] The explosion-proof block is a cuboid. The lines are stainless steel chains 3. The support frame is constructed of H-beams.

[0030] Use of the above-mentioned explosion-proof baffles:

[0031] The slag produced during the production of stainless steel in an AOD furnace is extremely hot, typically between 1500 and 1700 degrees Celsius. When this high-temperature slag is poured into a water quenching tank, it is dispersed by a high-speed airflow and explodes, splashing onto the explosion-proof baffle.

[0032] The aforementioned explosion-proof baffle is designed with a segmented explosion-proof block structure, with each block containing half sand. Under the influence of the force and the sand, each explosion-proof block will shake and be subjected to force asynchronously. The forces exerted by the explosion-proof blocks on the support will cancel each other out, avoiding the problems of easy damage and difficult maintenance and replacement of existing integral explosion-proof baffles. This also improves the durability, safety, and economy of the explosion-proof baffle.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
