Description

Technical Field

[0001] The invention belongs to the technical field of archway-type frame casting, and in particular relates to a casting system of the archway-type frame. Background Art

[0002] The arch, also known as the frame or frame body, is an important component of hot rolling, cold rolling, continuous rolling and other rolling mills. Due to the harsh working environment of the rolling mill, during the operation, the rollers will bring a great impact to the arch through the bearing seat, which requires the arch-type frame of the rolling mill to have good structural strength and internal quality.

[0003] In the prior art, during the production and processing of the arch-type frame, the frame is cast in a lying state. Due to the huge size of the frame, even if more risers are added to the casting system of the frame, after the molten steel is cast, shrinkage holes will still appear at the positions on the frame where no risers are set. The places where shrinkage holes appear on the frame need to be dug out and welded later, which will directly reduce the intrinsic quality of the frame and reduce the durability of the frame.

[0004] Since the rack itself is relatively large in size, and the size of the riser provided on the rack is also relatively large, the area of ​​the connection between the riser and the rack is relatively large, which will be disadvantageous for removing the riser from the rack.

[0005] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Summary of the invention

[0006] The object of the present invention is to provide a casting system for an arch-type frame to at least solve the above-mentioned problems existing in the prior art.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] A casting system for a memorial arch frame, the casting system comprising a frame body, a plurality of riser units being arranged on the upper surface of the frame body;

[0009] The riser unit comprises a cylindrical riser and a riser pedestal, wherein the cylindrical riser is located above the riser pedestal;

[0010] The riser seat is provided with convex shoulders on both sides, and the two convex shoulders of the riser seat are symmetrically arranged around the cylindrical riser. The lateral dimension of the riser seat is larger than the diameter of the cylindrical riser, and the height of the convex shoulders is smaller than the height of the cylindrical riser.

[0011] As described above, in the casting system of the arch-type frame, preferably, a main connecting channel is provided between adjacent riser units and between the bosses of adjacent riser seats, and the main connecting channel is used to connect the bosses of adjacent riser units.

[0012] In the casting system of the arch-type frame as described above, preferably, a branch channel is provided on the main connecting channel, and the branch channel is perpendicular to the main connecting channel.

[0013] In the casting system of the arch-type frame as described above, preferably, a transverse baffle is provided in the riser pedestal, the transverse baffle runs through the length direction of the riser pedestal, and the transverse baffle is located on the center line of the width direction of the riser pedestal.

[0014] In the casting system of the arch-type frame as described above, preferably, a plurality of through holes are arranged on the transverse baffle, and the through holes are used to connect two sides of the transverse baffle.

[0015] In the casting system of the arch-type frame as described above, preferably, a longitudinal baffle is further provided in the riser pedestal, the longitudinal baffle runs through the width direction of the riser pedestal, and the longitudinal baffle is located on the center line of the length direction of the riser pedestal.

[0016] In the casting system of the arch-type frame as described above, preferably, a plurality of longitudinal support plates are evenly distributed on both sides of the transverse baffle, and the longitudinal support plates are perpendicular to the transverse baffle.

[0017] In the casting system of the arch-type frame as described above, preferably, there is a gap between the longitudinal support plate and the edge of the riser pedestal.

[0018] In the casting system of the arch-type frame as described above, preferably, the transverse baffle, the longitudinal baffle and the longitudinal support plate are integrally pressed and formed by molding sand.

[0019] In the casting system of the arch-type frame as described above, preferably, the height of the transverse baffle and the longitudinal support plate located at the shoulder portion is higher than the shoulder portion, and the transverse baffle and the longitudinal support plate higher than the shoulder portion are pre-buried in the sand box of the frame.

[0020] Beneficial effects:

[0021] In this casting system, a riser unit with a convex shoulder riser base can compensate for the shrinkage of a larger area of ​​the frame body, which not only ensures the intrinsic quality of the frame, but also does not add too many riser structures, reduces the amount of casting molten steel, and further saves the production cost of the frame.

[0022] The main connecting channel has two functions. It not only ensures that the shoulder is filled with molten steel, so that the shoulder can better play its shrinkage compensation role; it also plays a certain shrinkage compensation role, which is beneficial to improving the internal quality of the frame.

[0023] The horizontal baffle and the vertical baffle cooperate with each other to divide the riser base into multiple small units, further reducing the connection area between each small unit in the riser base and the rack body, so as to reduce the connection strength between each small unit and the rack body, thereby making it easier to separate the riser unit from the rack body.

[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0029] In the description of the present invention, the terms "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention. The terms "connected" and "connected" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0031] According to a specific embodiment of the present invention, Figure 1-2As shown, the present invention provides a casting system for an arch-type frame, the casting system comprises a frame body 1 , and a plurality of riser units are arranged on the upper surface of the frame body 1 .

[0032] The riser unit comprises a cylindrical riser 2 and a riser base 3 , wherein the cylindrical riser 2 is located above the riser base 3 .

[0033] Boss portions 4 are provided on both sides of the riser pedestal 3 . The two boss portions 4 of the riser pedestal 3 are symmetrically arranged around the cylindrical riser 2 . The lateral dimension of the riser pedestal 3 is larger than the diameter of the cylindrical riser 2 , and the height of the boss portions 4 is smaller than the height of the cylindrical riser 2 .

[0034] In the casting system, the traditional riser structure is improved, a riser base 3 is arranged below the riser, and convex shoulders 4 are arranged on both sides of the riser base 3. The riser base 3 and the convex shoulders 4 on both sides greatly expand the lateral size of the cylindrical riser 2, so that the entire riser unit can cover a larger surface of the frame body 1, and then, without increasing the cylindrical riser 2 structure, a riser unit with a riser base 3 with a convex shoulder 4 can be used to compensate for a larger area of ​​the frame body 1, which not only ensures the intrinsic quality of the frame, but also does not increase too many riser structures, reduces the amount of molten steel used in casting, and further saves the production cost of the frame.

[0035] A main connection channel 8 is provided between adjacent riser units and between the convex shoulders 4 of adjacent riser seats 3 , and the main connection channel 8 is used to connect the convex shoulders 4 of adjacent riser units.

[0036] In one embodiment of the present application, a main connecting channel 8 is provided to connect the bosses 4 that are close to each other in adjacent riser units. The main connecting channel 8 has two functions. First, since the height of the boss 4 is lower than the cylindrical riser 2 and the lateral dimension of the boss 4 is larger, during casting, the molten steel can pass through all the bosses 4 through the main connecting channel 8 to ensure that the bosses 4 are filled with molten steel, so that the bosses 4 can better play their shrinkage compensation role. Second, the main connecting channel 8 covers the frame body 1, so that the main connecting channel 8 plays a certain shrinkage compensation role, which is beneficial to improving the intrinsic quality of the frame.

[0037] A branch channel 9 is provided on the main connecting channel 8 , and the branch channel 9 is perpendicular to the main connecting channel 8 .

[0038] In one embodiment of the present application, a branch channel 9 is provided perpendicular to the main connecting channel 8 so that the branch channel 9 covers the surface of the frame body 1 as much as possible, so that the branch channel 9 can compensate for a larger range of the frame body 1 to improve the casting quality of the frame.

[0039] A transverse baffle 5 is provided in the riser pedestal 3 . The transverse baffle 5 runs through the length direction of the riser pedestal 3 , and the transverse baffle 5 is located on the center line of the width direction of the riser pedestal 3 .

[0040] In one embodiment of the present application, a transverse baffle 5 is provided in the riser base 3, and the riser base 3 serves as a connecting part between the riser and the frame body 1. The riser base 3 is vertically divided into two parts by the transverse baffle 5, thereby reducing the connection area between each part of the riser unit and the frame body 1; after the casting is completed, when the riser unit needs to be removed from the frame body 1, the connection strength between the riser unit and the frame body 1 is lower, which makes it easier to remove the riser unit on the frame body 1.

[0041] A plurality of through holes are arranged on the transverse baffle 5, and the through holes are used to connect the two sides of the transverse baffle 5. In one embodiment of the present application, through holes are arranged on the transverse baffle 5, so that molten steel can flow through the through holes on both sides of the transverse baffle 5, thereby ensuring the consistency of the temperature of the molten steel on both sides of the transverse baffle 5 as much as possible, so that the cooling process of the frame casting is more uniform.

[0042] A longitudinal baffle 6 is also provided in the riser pedestal 3 . The longitudinal baffle 6 runs through the width direction of the riser pedestal 3 , and the longitudinal baffle 6 is located on the center line of the length direction of the riser pedestal 3 .

[0043] In one embodiment of the present application, a vertical baffle is provided in the riser base 3, and the riser base 3 is divided into two parts in the horizontal direction by the vertical baffle. The horizontal baffle 5 cooperates with the vertical baffle to divide the riser base 3 into a plurality of small units, thereby further reducing the connection area between each small unit in the riser base 3 and the rack body 1, so as to reduce the connection strength between each small unit and the rack body 1, thereby making it easier to separate the riser unit from the rack body 1.

[0044] A plurality of longitudinal support plates are evenly distributed on both sides of the transverse baffle plate 5 , and the longitudinal support plates are perpendicular to the transverse baffle plate 5 .

[0045] In one embodiment of the present application, since the transverse baffle 5 has a long span along the length direction, multiple longitudinal support plates are arranged on both sides of the transverse baffle 5, which is beneficial for further dividing the riser base 3 into smaller units, so as to further reduce the connection strength between each unit in the riser base 3 and the frame body 1, thereby facilitating the removal of the riser unit from the frame body 1.

[0046] In one embodiment of the present application, the transverse baffle 5, the longitudinal baffle 6 and the longitudinal support plate are formed by pressing molding sand. The transverse baffle 5, the longitudinal baffle 6 and the longitudinal support plate are coated with high-temperature resistant paint on the side facing the machine body to ensure the molding quality of the machine body surface. The transverse baffle 5, the longitudinal baffle 6 and the longitudinal support plate are pre-buried in the sand box of the frame.

[0047] There is a gap between the longitudinal support plate and the edge of the riser pedestal 3. In one embodiment of the present application, a gap is set between the longitudinal support plate and the edge of the riser pedestal 3, so that the molten steel on both sides of the longitudinal support plate can flow to each other, thereby ensuring the consistency of the molten steel temperature on both sides of the longitudinal support plate as much as possible, making the cooling process of the frame casting more uniform.

[0048] In other embodiments, no gap may be set between the longitudinal support plate and the edge of the riser base 3. In this case, a through hole may be set on the longitudinal support plate, and the molten steel on both sides of the longitudinal support plate flows through the through holes to ensure the consistency of the molten steel temperature on both sides of the longitudinal support plate, thereby ensuring that the cooling process of the large casting is more uniform.

[0049] The transverse baffle 5, the longitudinal baffle 6 and the longitudinal support plate are integrally pressed and formed by molding sand. Among them, the transverse baffle 5, the longitudinal baffle 6 and the longitudinal support plate are integrally formed and manufactured, which makes it easier to install the transverse baffle 5, the longitudinal baffle 6 and the longitudinal support plate in the sand box of the frame.

[0050] The height of the transverse baffle 5 and the longitudinal support plate located at the convex shoulder portion 4 is higher than the convex shoulder portion 4, and the transverse baffle 5 and the longitudinal support plate higher than the convex shoulder portion 4 are pre-buried in the sand box of the frame. In one embodiment of the present application, the transverse baffle 5 and the longitudinal support plate part higher than the convex shoulder portion 4 are pre-buried in the sand box of the frame, which not only facilitates the transverse baffle 5, the longitudinal baffle 6 and the longitudinal support plate to be fixed in the sand box of the frame, but also facilitates the transverse baffle 5, the longitudinal baffle 6 and the longitudinal support plate to be accurately installed and positioned in the sand box of the frame.

[0051] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
