DETAILED DESCRIPTION

[0030] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0032] In the metallurgical industry, the temperature of molten iron and steel is crucial for subsequent production processes. To reduce heat loss during transportation and storage, insulation materials are installed inside the ladle lids. Good insulation can reduce energy consumption and improve production efficiency. For example, in the steelmaking process, from tapping from the converter to the continuous casting step, effectively maintaining the temperature of the molten steel can reduce subsequent heating steps, saving significant energy.

[0033] Properly installed insulation ensures temperature uniformity in molten iron and steel. Stable temperatures improve the quality of metallurgical products and reduce defects caused by temperature fluctuations. Good insulation reduces heat loss to the surrounding environment, lowering the temperature in the work area and improving the working environment. Furthermore, reduced heat loss reduces thermal pollution. From a safety perspective, lining insulation lowers the temperature of the covering surface, reducing the risk of burns and other safety incidents.

[0034] However, the conventional method for installing thermal insulation materials is a welding fixation method, in which the lining and the cover are connected together by welding. Once the welding is completed, the lining is difficult to replace and lacks flexibility.

[0035] Based on this, the disclosed embodiments provide a method for quickly installing and repairing the inner lining of an iron ladle or steel ladle cover. This technical solution improves production efficiency: rapid installation reduces equipment downtime, improving steel production efficiency; the modular design and rapid installation of fixtures reduce installation and maintenance costs; and the modular lining allows for individual replacement of damaged modules, facilitating maintenance and management. The precise positioning and excellent sealing of the individual insulation material modules by the first and second fixtures improves the service life of the iron ladle cover and product quality.

[0036] The following is a detailed description of the method for quickly installing and repairing the inner lining of the iron ladle / steel ladle cover through specific embodiments:

[0037] Reference Figures 1 to 5 As shown, in a first aspect of the present disclosure, a method for quickly installing and repairing the inner lining of an iron ladle / steel ladle cover is provided, comprising the following steps:

[0038] The thermal insulation material is laid out by determining the overall size of the thermal insulation material according to the size of the cover, dividing the overall thermal insulation material into a plurality of thermal insulation material unit modules 1, and laying them out along the edges of the large arc segment and / or the small arc segment of the cover until the entire range of the cover is covered;

[0039] Specifically, the standard insulation foam lining of the ladle / steel ladle cover utilizes multiple layers of zirconium-containing fibers bound with bands, with the height matching the ladle cover structure. The entire insulation foam block is disassembled into several insulation material unit modules 1, which are then tightened against the inner edge of the large arc section of the ladle cover, where the steel structure is intact. This tightening method can be pre-tightened using other mechanisms in preparation for the insulation step.

[0040] The thermal insulation material is fixed. Each time a group of thermal insulation material unit modules 1 is arranged, the thermal insulation cotton unit module is fixed along the arrangement direction of the thermal insulation material unit module 1 through the first fixing member 2. A fixing hole 31 is set at the position where the first fixing member 2 contacts the thermal insulation material unit module 1. After the thermal insulation cotton module is fixed to the preset position, the first fixing member 2 is fixed to the cover.

[0041] Specifically, in some embodiments, the insulation material unit module 1 of the present disclosure can be configured as a rectangular parallelepiped, cylindrical, or irregularly shaped structure. The present disclosure specifically configures the insulation material unit module 1 as a rectangular parallelepiped to accommodate most package shapes, making installation of the insulation material unit module 1 easier. The layout direction of the insulation material unit module 1 is the length and width of the insulation material unit module 1. As described above, the first fixing member 2 can be configured to secure the insulation material unit module 1 in the length and / or width direction, thereby securing the insulation material unit module 1 within the package for the initial tightening after pre-fixing. For example, when installing the first insulation material unit module 1, the first fixing member 2 is used to secure the insulation material unit module 1 in the length direction, so that one side of the insulation material unit module 1 presses against the inner edge of the package, while the other side presses against the first fixing member 2. Alternatively, multiple insulation material unit modules 1 can be arranged in a row along the length direction, and each insulation material unit module 1 is then tightened with the first fixing member 2. It should be noted that each thermal insulation material unit module 1 is not limited to using one first fixing member 2 , and adaptive adjustment is performed according to the size of the thermal insulation material unit module 1 and / or the size of the first fixing member 2 .

[0042] The thermal insulation material is penetrated by the second fixing member 3 from the fixing hole into the thermal insulation material unit module 1 , and after penetrating into the adjacent thermal insulation material unit module 1 , the second fixing member 3 is fixed to the first fixing member 2 .

[0043] Specifically, after one row of thermal insulation material unit modules 1 is set up using the above-described embodiment, an adjacent second row of thermal insulation material unit modules 1 is set up using one or more of the above-described methods. At this time, the first and second rows of thermal insulation material unit modules 1 are connected by the second fixing members 3 to achieve mutual pulling between the two rows of thermal insulation material unit modules 1, thereby preventing the thermal insulation material unit modules 1 from falling off. It should be noted that when setting the first fixing members 2, the first fixing members 2 of the front and rear rows are staggered as much as possible so that the second fixing members 2 can penetrate the adjacent thermal insulation material unit modules 1 through the fixing holes 31.

[0044] In some implementations, before the step of arranging the thermal insulation material, the bag cover is also cleaned to remove oil, rust and other impurities on the bag cover.

[0045] In some implementations, the insulation material unit module 1 corresponding to the small arc segment is trimmed so that the edge shape of the insulation material unit module 1 is adapted to the small arc segment, thereby improving the lining coverage effect and thus improving the insulation performance.

[0046] In some embodiments, the first fixing member 2 is configured as a rectangular stainless steel fixing member, and the height of the first fixing member 2 is 40% to 50% of the thickness of the thermal insulation material unit module 1 .

[0047] In this embodiment, the first fixing member 2 is configured as a rectangular stainless steel fixing member, specifically a rectangular shape. The height of the first fixing member 2 is 40% to 50% of the thickness of the thermal insulation material unit module 1. When the height of the first fixing member 2 is less than 40% of the thickness of the thermal insulation material unit module 1, the fixing effect of the first fixing member 2 is reduced, which is not conducive to the fixation of the thermal insulation material unit module 1. When the height of the first fixing member 2 is greater than 50% of the thickness of the first thermal insulation material unit module 1, the thermal insulation material unit module 1 has less space for the second fixing member 3 to penetrate. The penetration of the second fixing member 2 will inevitably squeeze the thermal insulation material unit module 1 from the inside to the outside. The small penetration position will cause local bulges of the thermal insulation material unit module 1.

[0048] In some embodiments, the fixing holes are located in the upper quarter of the height of the first fixing member 2. This facilitates welding of the first fixing member 2 and installation of the second fixing member. If the fixing holes are located in the lower portion of the first fixing member 2 (on the side close to the welding point), the operating range for installing the second fixing member 3 is relatively limited, making it difficult to install and secure the second fixing member 3.

[0049] In some embodiments, the second fixing member 3 is set as a steel bar, and the length of the second fixing member 3 is set to 1.3 to 1.5 times the width of the thermal insulation material unit module 1. When the length and width of the thermal insulation material unit module 1 are inconsistent, the second fixing member 3 of the present disclosure is all passed through the width direction of the thermal insulation material unit module 1, and the length of the second fixing member 3 is 1.3 to 1.5 times the width of the thermal insulation material unit module 1 to ensure that the second fixing member 3 can pass through the adjacent thermal insulation material unit module 1 and can fix it. When the length of the second fixing member 3 is less than 1.3 times the width of the thermal insulation material unit module 1, the second fixing member 3 does not firmly fix the adjacent thermal insulation material unit module 1; when the length of the second fixing member 3 is greater than 1.5 times the width of the thermal insulation material unit module 1, the length of the second fixing member 3 is too long, which is not conducive to passing through the thermal insulation material unit module 1.

[0050] In some embodiments, the thermal insulation material unit modules 1 are arranged alternately in the horizontal and vertical directions along the arrangement direction of the thermal insulation material unit modules 1. Specifically, the thermal insulation material unit modules 1 can be installed in a 2-layer horizontal + 2-layer vertical cycle arrangement, or a 2-layer horizontal + 1-layer vertical cycle arrangement; or a 1-layer horizontal + 1-layer vertical cycle arrangement; or a 1-layer horizontal + 2-layer vertical cycle arrangement. By arranging the thermal insulation material unit modules 1 alternately in the horizontal and vertical directions, the stress of the thermal insulation material unit modules 1 in the same direction is reduced to ensure the stability of the overall structure. The above-mentioned horizontal and vertical directions are understood to mean that the surfaces of the thermal insulation material unit modules 1 in the length direction are arranged in a longitudinal direction; and the surfaces of the thermal insulation material unit modules 1 in the length and width direction are arranged in a horizontal direction.

[0051] In the second aspect of the present disclosure, a device is provided for quickly installing the insulation material of the lining of the iron ladle / steel ladle cover, which is applied to the quick installation and repair method of the lining of the iron ladle / steel ladle cover provided in the first aspect of the present disclosure, including a fixed connector 4 and an operating rod 5, the fixed connector 4 is connected to the end of the operating rod 5, and the fixed connector 4 is used to fix the relative position of the first fixing member 2 and the insulation cotton unit module, wherein the operating rod 5 has an abutment surface, and the abutment surface is provided at one end of the operating rod 5 where the fixed connector 4 is provided; when the fixed connector 4 is in a connected state with the fixing hole of the first fixing member 2, the abutment surface is used to abut the first fixing member 2.

[0052] The diameter of the end of the fixing member 4 used to connect to the fixing hole should be smaller than the diameter of the fixing hole to ensure that it can be inserted through the small hole. After the end of the fixing member 4 is inserted into the fixing hole to form a connection, the position of the first fixing member 2 can be adjusted. After reaching the preset position, the abutment surface of the operating rod 5 is used to tighten the first fixing member 2 against the thermal insulation material unit module 1.

[0053] In some embodiments, the fixed connection member 4 includes a first fixed rod 41 and a second fixed rod 42. The first fixed rod 41 and the second fixed rod 42 are connected by an adjusting member 43. The first fixed rod 41 is connected to the operating rod 5. The adjusting member 43 is used to adjust the angle at the connection between the second fixed rod 42 and the first fixed rod 41.

[0054] The fixed connection member 4 disclosed in the present invention includes a first fixed rod 41 and a second fixed rod 42, and the first fixed rod 41 and the second fixed rod 42 are connected by an adjusting member 43, so that the angle of the second fixed rod 42 is adjustable so as to better connect with the first fixed member 2. Specifically, the angle between the second fixed rod 42 and the first fixed rod 41 can be adjusted to 150 degrees, so that the operator can obliquely embed it into the fixing hole, and the oblique force of the operating rod 5 is more conducive to tightening. When the thermal insulation material unit module 1 is disassembled or the installation space is relatively limited, the angle at the connection between the second fixed rod 42 and the first fixed rod 41 can be adjusted by the adjusting member 43 to meet the space usage requirements. Specifically, the adjusting member 43 can be selected as a rotating shaft or the second fixed rod 42 is hinged to the first fixed rod 41. The adjusting member 43 can be provided with a fixing portion, such as a bolt, a buckle or other mechanism to fix the relative angle after the angle between the second fixed rod 42 and the first fixed rod 41 is adjusted.

[0055] In some embodiments, the operating rod 5 is provided with an adjustment section 51 , and the adjustment section 51 is used to adjust the length of the operating rod 5 .

[0056] In this embodiment, the adjustment section 51 is configured as a telescopic rod to adjust the length of the operating rod 5, or the entire operating rod 5 is configured as multiple connecting sections, and the overall length of the operating rod 5 is adjusted by adding or reducing connecting sections.

[0057] The specific data embodiment of the present disclosure is that the thermal insulation cotton lining of the iron bag cover is zirconium fiber, the single layer is about 600mm long, about 25mm thick, and about 200mm high (consistent with the thickness of the cover structure), and 12 layers are tied with straps to form a 300mm thick module. The whole piece of thermal insulation cotton is disassembled into several thermal insulation material unit modules 1, which are pressed tightly against the inner side of the edge of the large arc segment of the iron bag cover with intact steel structure. A corner of the whole thermal insulation cotton module is sawed off to adapt to the shape of the edge of the small arc segment and press it tightly. A rectangular first fixing part 2 of 80mm×60mm×8mm is used to press the lower part of the thermal insulation material unit module 1, and a fixing hole with a diameter of 12mm is provided at the upper 1 / 4 position in the height direction of the first fixing part 2. One person holds a device for quickly installing the insulation lining of the iron / steel ladle cover. The operating lever is set as a 1300mm long lightweight steel pipe with a diameter of 20-30mm. A stainless steel bar 60-80mm long and 10mm in diameter is welded to one end. The part of the stainless steel bar longer than the steel pipe and the part welded to the steel pipe are bent at an angle of about 150 degrees. The stainless steel bar at the front end is passed through the fixing hole and firmly pushed in. A second person hammers down the first fixing piece 2. A third person welds the lower part of the first fixing piece 2 to the covering steel structure. A second fixing piece 3, about 450mm long and 10mm in diameter, is passed through the fixing hole and hammered down until it passes through the previous (adjacent) insulation material unit module 1 to a depth of 100mm. The steel bar is then firmly welded to the small hole of the fastener, completing a set of insulation material unit modules 1 fixed with the first fixing piece 2 and the second fixing piece 3.
