Description

Technical Field

[0001] This utility model relates to the field of blast furnace ironmaking technology, and in particular to a modular blast furnace brick lining mold. Background Technology

[0002] Due to the extreme operating conditions (high temperature, high pressure, strong erosion, and frequent mechanical impact) constantly presented by the blast furnace taphole, the performance requirements for the refractory materials in the taphole lining are far higher than in other parts of the blast furnace. The taphole lining is not constructed from a single shape of brick, but rather from various irregularly shaped bricks laid in a staggered pattern to minimize gaps and prevent molten iron leakage. Existing brick production equipment often integrates mold frames and molds, with multiple molds on a single frame for large-scale mass production. The problem with this design is that if one mold wears out or deforms, the entire assembly must be replaced, easily leading to resource waste. Summary of the Invention

[0003] To address the above problems, this utility model provides a modular blast furnace brick lining mold.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A modular blast furnace brick lining mold includes a mold frame and a mold cover on the mold frame. The size and shape of the lower surface of the mold cover are adapted to the size and shape of the upper surface of the mold frame. It also includes cavity modules. The mold frame is provided with a number of cavity placement slots for placing cavity modules. The cavity placement slots are rectangular grooves. The depth of the cavity placement slots is less than the height of the mold frame. The shape, size, and depth of the cavity module placement slots are adapted to the shape, size, and height of the cavity modules.

[0005] Furthermore, the cavity module is a rectangular block, comprising a cavity module upper plate and a cavity module base. The cavity module upper plate is fixedly connected above the cavity module base, and the cavity module base is located at the center of the bottom surface of the cavity module upper plate. The shape of the upper surface of the cavity module upper plate is consistent with the shape of the bottom surface of the cavity module base, and the area of ​​the upper surface of the cavity module upper plate is larger than the area of ​​the bottom surface of the cavity module base. The shape and area of ​​the upper surface of the cavity module upper plate are adapted to the shape and area of ​​the bottom of the cavity module placement groove. A molding groove for filling molding material is provided on the upper surface of the cavity module, and the depth of the molding groove is less than the height of the cavity module.

[0006] Furthermore, the mold frame is also provided with several rectangular bolt slots, which are located at the top edge of the cavity placement slot. Mold frame bolt holes are provided in the bolt slots. Side ears are provided on the four outer walls of the upper plate of the cavity module. The shape and size of the upper surface of the side ears are adapted to the shape and size of the lower bottom surface of the bolt slot. A cavity module bolt hole is provided at the center of the side ear. The shape and size of the cavity module bolt hole are adapted to the shape and size of the mold frame bolt hole. The number and position of the side ears correspond to the number and position of the bolt slots.

[0007] Furthermore, at least two bolt slots are provided on each side of the cavity placement groove, and the bolt slots are symmetrically arranged along the center line of that side.

[0008] Furthermore, the mold frame is also provided with a number of pin slots for engaging with pins. The mold cover includes a cover plate and pins. The cover plate is a rectangular plate, and the shape and size of the lower surface of the cover plate are adapted to the shape and size of the upper surface of the mold frame. Pins are fixedly connected to the lower surface of the cover plate. The number and position of the pins are adapted to the number and position of the pin slots on the mold frame, and the length of the pins is adapted to the depth of the pin slots.

[0009] Furthermore, the number of the pin slots is at least four, which are respectively set at the corresponding positions of the four side lines on the upper surface of the mold frame.

[0010] Furthermore, the front end of the pin is provided with a chamfer or rounded corner.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The modular blast furnace brick lining mold of this utility model disassembles the integrated brick lining mold into several independent cavity modules. Compared with the traditional integrated brick lining mold, when a certain forming groove is damaged, the entire mold needs to be replaced. With this new model, when the forming groove is damaged, only the corresponding cavity module needs to be replaced, without replacing the entire mold, which greatly avoids the waste of resources.

[0017] Preferably, in order to enable the pin 302 to better perform its fixing function, the number of pin slots 104 is at least four, which are respectively set at the corresponding positions of the four side lines on the upper surface of the mold frame 100.

[0018] Furthermore, the mold frame 100 is also provided with a number of rectangular bolt grooves 102, which are located at the top edge of the cavity placement groove 101, and mold frame bolt holes 103 are provided in the bolt grooves 102.

[0019] Preferably, to ensure that the cavity module 200 is more securely installed on the mold frame 100, at least two bolt slots 102 are provided on each side of the cavity placement slot 101, and the bolt slots 102 are symmetrically arranged along the center line of that side.

[0020] like Figure 4As shown, the mold cover 300 includes a cover plate 301 and a pin 302. The cover plate 301 is a rectangular plate, and the shape and size of the lower surface of the cover plate 301 are adapted to the shape and size of the upper surface of the mold frame 100. A pin 302 is fixedly connected to the lower surface of the cover plate 100. The number and position of the pins 302 are adapted to the number and position of the pin slots 104 on the mold frame 100, and the length of the pins 302 is adapted to the depth of the pin slots 104.

[0021] Preferably, to make it easier for the pin 302 to be inserted into the pin slot 104, a chamfer or rounded corner is provided at the front end of the pin 302.

[0022] like Figure 5 As shown, the cavity module 200 is a rectangular block. The cavity module 200 includes a cavity module upper plate 204 and a cavity module base 205. The cavity module upper plate 204 is fixedly connected above the cavity module base 205. The cavity module base 205 is located at the center of the bottom surface of the cavity module upper plate 204. The shape of the upper surface of the cavity module upper plate 204 is consistent with the shape of the bottom surface of the cavity module base 205. The area of ​​the upper surface of the cavity module upper plate 204 is larger than the area of ​​the bottom surface of the cavity module base 205.

[0023] Preferably, to prevent the top of the bolt from protruding when the cavity module 200 is installed in the cavity module placement slot 101 by bolts, which would prevent the mold cover 300 from covering the mold frame 100, the side ear 202 is positioned close to the bottom surface of the cavity module upper plate 204 and away from the upper surface of the cavity module upper plate 204.

[0024] In use, insert the cavity module 200 into the cavity module placement slot 101. At this time, the side ear 202 is embedded in the bolt slot 102. The bolts are passed through the cavity module bolt hole 203 and the mold frame bolt hole 103 in sequence. The cavity module 200 is fixed in the cavity module placement slot 101 by the bolts. Then, the molding slot 201 is filled with molding material. Finally, the pin 302 is aligned with the pin slot 104 and inserted. The mold cover 300 is placed on the mold frame 100 to complete the overall closure of the mold.

[0025] As described above, the modular blast furnace brick lining mold of this utility model disassembles the integrated brick lining mold into several independent cavity modules. Compared with the traditional integrated brick lining mold, which requires the replacement of the entire mold when a certain forming groove is damaged, this new model only requires the replacement of the corresponding cavity module when the forming groove is damaged, without the need to replace the entire mold, which greatly avoids the waste of resources.
