Description

Technical Field

[0001] The utility model belongs to the technical field of steel ingot casting, in particular to an ingot mould chassis for pouring steel ingots. Background Art

[0002] The traditional casting hole in the chassis mold for pouring steel ingots is a tapered hole, into which a mold base brick (refractory material) is placed. The gap between the mold base brick and the chassis hole is generally filled with refractory mud or asbestos thread. Because the refractory mud is washed by the molten steel, it easily enters the molten steel, affecting product quality. Asbestos, a carcinogen, has restricted use. Furthermore, after pouring, the mold base brick often floats up, and the filling material falls off. This leads to severe melt loss in the chassis, widening the gap, and creating a vicious cycle that makes filling more difficult. This also poses a significant risk to the quality of the steel ingot and the safety of the pouring. The filling mud enters the molten steel, creating foreign inclusions, and the mold base brick floats up, creating the risk of steel running down the runner. Therefore, improvements are necessary.

[0019] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0020] An ingot mold chassis for pouring steel ingots according to an embodiment of the present application is as follows: Figure 1As shown, it includes: a chassis body 1, a flow channel 11 is longitudinally provided in the middle of the chassis body 1, and the flow channel 11 includes a first arc flow channel 12, a first cylindrical flow channel 13 and a second cylindrical flow channel 14 connected in sequence from top to bottom; the diameter of the second cylindrical flow channel 14 is larger than the diameter of the first cylindrical flow channel 13; a step limit is formed between the first cylindrical flow channel 13 and the second cylindrical flow channel 14 to limit the mold bottom bricks so that the mold bottom bricks cannot move upward during the pouring process to ensure safety.

[0021] In one embodiment, the center line of the first cylindrical flow channel 13 and the center line of the second cylindrical flow channel 14 coincide with each other.

[0022] As an example, the height of the second cylindrical flow channel 14 is 80 mm; the height of the first cylindrical flow channel 13 is 60 mm; and the radius of the arc of the first arc flow channel 12 is 470 mm. The inner wall of the first cylindrical flow channel 13 forms a predetermined angle with the horizontal plane. Furthermore, the diameter of the upper end surface of the first cylindrical flow channel 13 is smaller than the diameter of the lower end surface of the first cylindrical flow channel 13. The diameter of the upper end surface of the first cylindrical flow channel 13 is 125 mm, and the diameter of the lower end surface of the first cylindrical flow channel 13 is 161 mm; the diameter of the second cylindrical flow channel 14 is 165 mm.

[0023] In one embodiment, symmetrical hanging posts 15 are further provided on the sides of the chassis body 1 , and the ends of the hanging posts 15 form limiting blocks 16 to facilitate the limiting of the lifting rope.

[0024] In one embodiment, a mold bottom brick 2 is further included. The mold bottom brick 2 cooperates with the flow channel 11 , and the mold bottom brick 2 is adapted to the corresponding first cylindrical flow channel 13 and second cylindrical flow channel 14 .

[0025] Further, if Figure 2 As shown, the mold base brick 2 includes a mold base brick body 21. A through hole 24 is longitudinally formed in the middle of the mold base brick body 21. The centerline of the through hole 24 coincides with the centerline of the second cylindrical flow channel 14. The mold base brick body 21 includes a first mold base brick connector 22 adapted to fit the first cylindrical flow channel 13 and a second mold base brick connector 23 adapted to fit the second cylindrical flow channel 14. The first mold base brick connector 22 and the second mold base brick connector 23 are integrally formed. The outer wall of the second mold base brick connector 23 forms a predetermined angle with the horizontal plane. Furthermore, the diameter of the upper end surface of the second mold base brick connector 23 is smaller than the diameter of the lower end surface of the second mold base brick connector 23.

[0026] The outer wall of the first mold bottom brick connector 22 forms a preset angle with the horizontal plane. Furthermore, the diameter of the upper end surface of the first mold bottom brick connector 22 is smaller than the diameter of the lower end surface of the first mold bottom brick connector 22 .

[0027] As an example, the diameter of the upper end surface of the through hole 24 is 70 mm, and the diameter of the lower end surface of the through hole 24 is 60 mm, that is, the through hole 24 is a through hole with a variable diameter from large to small. The height of the first mold bottom brick connector 22 is 60 mm, and the height of the second mold bottom brick connector 23 is 80 mm; the diameter of the upper end surface of the first mold bottom brick connector 22 is 123 mm, and the diameter of the lower end surface of the first mold bottom brick connector 22 is 153 mm, that is, the outer wall of the first mold bottom brick connector 22 forms a preset angle with the horizontal plane; the diameter of the upper end surface of the second mold bottom brick connector 23 is 156 mm, and the diameter of the lower end surface of the second mold bottom brick connector 23 is 160 mm, that is, the outer wall of the second mold bottom brick connector 23 forms a preset angle with the horizontal plane.

[0028] In this embodiment, a step is added to limit the position of the mold, preventing it from moving upward during the pouring process, ensuring its safety. Furthermore, installation is simple and convenient. During mold assembly, the mold base brick 2 is placed within the runner of the chassis, and the lower half is secured with fire clay. The upper half does not need to be filled, making installation easy and convenient. Using the newly designed ingot mold chassis and its matching mold base bricks, the mold base bricks will not float upward. Furthermore, clay will not enter the gap between the upper half of the mold base brick and the ingot mold, i.e., the interior of the steel ingot. This greatly increases pouring safety and effectively improves the steel ingot flaw detection pass rate.
