Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments, but not all embodiments of the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Referring to the attached drawings 1-2, the tool for preventing the hot billet from deforming of the billet continuous casting machine comprises a handle 1, an upper contact end 2 and force bearing ends 3, wherein the force bearing ends 3 are positioned on two sides of the upper contact end 2 and are perpendicular to the upper contact end 2, the two force bearing ends 3 are parallel to each other, the force bearing ends 3 and the upper contact end 2 are connected to form a groove-shaped structure with a U-shaped cross section, and one side, far away from the force bearing end 3, of the center of the upper contact end 2 is connected with the handle 1.
The upper contact end 2 and the force bearing end 3 are made of metal materials.
The length of the upper contact end 2 is 1000-1020 mm, and the height of the bearing end 3 is 160 mm.
The connection mode of the bearing end 3 and the upper contact end 2 is welding or the bearing end 3 is formed by respectively bending two sides of the upper contact end 2 by 90 degrees.
The upper contact end 2 and the bearing end 3 are metal baffle plates or are made of a plurality of metal strips.
The handle 1 is made of steel bars and is welded in the center of the upper contact end 2.
The continuous billet caster requires continuous multi-stream production, so when equipment such as a casting blank separator or a cooling bed breaks down, the faults must be processed while production, before the equipment faults are processed, a hot casting blank produced by a casting machine must be lifted off by a crown block, the casting blank accumulation is prevented from influencing the continuous production of the casting machine, 6 casting blanks lifted off by the crown block are clamped, and when the 6 casting blanks are arranged on the ground, the total width of the casting blanks is as follows: 160mm is multiplied by 6 and is 960mm, because every 6 casting blanks clamped are not mutually abutted when falling to the ground, the error is 20-30 mm on the basis of the total width, namely the actual width is 980-990 mm, the cooling rate of the middle part and the edge part is different, the casting blanks on the edge part can be bent and deformed, thereby causing waste products, the tool of the utility model can be placed at the two ends of each casting blank clamped to forcibly prevent the two ends from being bent and deformed in the cooling process,
the length of the upper contact end 2 is 1000 mm-1020 mm, and the main reasons are as follows: firstly, every 6 casting blanks clamped by the overhead travelling crane are not abutted to each other when falling to the ground, and when a gap exists, the two ends of the casting blanks can still be placed to achieve the purpose of preventing cooling deformation; secondly, although the cooling deformation of the casting blank is slow, the deformation force is still larger, and the impact of the deformation stress on the anti-blocking tool can be reduced by a slow release interval, so that the anti-blocking tool is prevented from deforming. On the basis of 980-990 mm of the actual total width of 6 casting blanks, after the blanks are widened by 20-30 mm, the cooling deformation of the hot square blanks is 20-30 mm, the bending degree per meter of the square blanks is 1.7-2.5 mm/m through calculation, and the requirement that the bending degree of the casting blanks according to the national standard is not more than 20mm per meter is met.
When the tool is used, the tools are respectively installed at two ends of a casting blank, the handle 1 is held, 6 casting blanks are located between the bearing ends 3, the upper contact end 2 is in contact with the casting blank, the hot square blank is forcibly prevented from being scrapped due to cooling deformation, the resource waste caused by scrapping is avoided, the cost is saved, the national standard requirement is met, and the production quality and the production efficiency of an enterprise are improved.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
