[0002] With the continuous development of society and the continuous advancement of science and technology, the technology related to the manufacture of fused corundum bricks is also constantly improving. The production process of fused corundum products is to clarify the liquid melted in the electric arc furnace and then cast it into a pre-formed sand mold. After cooling, annealing and insulation, it is processed into products using diamond grinding tools. The casting process is to pour the liquid from the electric arc furnace into the sand mold through the furnace nozzle.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

The top insulation material 17 and the bottom insulation material 23 simultaneously play a good insulation role for the product sand mold 18 and the slurry. On the one hand, it is ensured that the slurry has good fluidity as much as possible, and on the other hand, it improves the quality of the product and improves the product qualification rate. A casting pipe 19 is fixedly connected to the top of each product sand mold 18, and a casting frame 8 is slidingly provided above the insulation box 1, and a diversion cavity 22 is opened in the casting frame 8. A plurality of openings 9 are opened on the inner walls on both sides of the diversion cavity 22, and an arc guide pipe 16 and a plurality of groups of limit blocks are fixedly connected to the two side surfaces of the casting frame 8. Each arc guide pipe 16 is arranged directly below the corresponding opening 9.

[0031] Each set of limit blocks includes two limit bars 10, which are symmetrically arranged on both sides of the corresponding openings 9, and a blocking plate 13 is inserted between the two limit bars 10. Each limit bar 10 is provided with a positioning port 6 for connecting the blocking plate 13, and each limit bar 10 is provided with a locking assembly. Each locking assembly includes two screws 14 threadedly mounted on the limit bar 10, and each limit bar 10 is provided with two threaded holes 31 for connecting the screws 14. The surface of the blocking plate 13 is provided with a plurality of grooves for connecting the screws 14. The lower inner wall of each positioning port 6 is set as a slope, and the two slopes on each set of limit blocks are set in an inverted eight shape.

[0032] An appropriate amount of blocking plates 13 can be inserted into the corresponding two limit bars 10. When the blocking plates 13 are fitted with the surfaces of the two positioning ports 6, one side surface of the blocking plates 13 is tightly attached to the outer surface of the casting frame 8, and the connection is well sealed. At this time, the blocking plates 13 can seal and block the openings 9. Then, one end of each screw 14 is passed through the threaded hole 31 and threadedly connected to the threaded hole 31 until one end of the screw 14 is tightly attached to the inner wall of the corresponding groove. This can effectively prevent the blocking plates 13 from moving at will, so that the blocking plates 13 can effectively seal and block the openings 9 for a long time. The setting of the inclined surface on the positioning port 6 can effectively prevent the slurry from flowing into the positioning port 6 and accumulating.

[0033] The lower inner wall of the diversion chamber 22 is set to an arc surface, and two symmetrical positioning grooves 24 are provided on the inner walls on both sides of the casting frame 8. The lower inner wall of each positioning groove 24 is set to an inclined inner wall. Multiple positioning grooves 24 are connected by two sealing strips 12, and the bottom of each sealing strip 12 is fixedly connected to a sealing plate 20. The lower surface of each sealing plate 20 is in contact with the arc surface, and each sealing strip 12 is connected to the casting frame 8 by two bolts 11. Two connecting grooves for connecting bolts 11 are provided on both side surfaces of the casting frame 8. The sealing strip 12 is inserted into the inside of the two positioning grooves 24.

After that, one end of each bolt 11 is passed through the sealing strip 12 and threadedly connected to the connecting groove, so that the interior of the diversion chamber 22 can be divided into two parts that are not connected to each other.

[0034] The insulation box 1 is provided with two symmetrically arranged limit grooves 21, each of which is slidably connected to a slider 15 inside the limit groove 21, and the two sliders 15 are fixedly connected to the lower surface of the casting frame 8. A cross block 5 is fixedly connected to one side surface of the casting frame 8, and a through groove is provided in the cross block 5. A slide rod 4 is vertically slidably connected to the through groove. A limit plate 2 is fixedly connected to the upper surface of the limit plate 2. A plurality of equidistantly arranged card blocks 3 are fixedly connected. The bottom of the slide rod 4 is provided with a card block 3 for connecting The card slot of block 3, a rectangular slot 28 is provided on the slide rod 4, the inside of the rectangular slot 28 is slidably connected to the slide plate 7, and the one side surface of the slide plate 7 is fixedly connected to the plug shaft 25, and the inner wall of one side of the through groove is provided with a circular groove 26 for connecting the plug shaft 25, and the inner walls on both sides of the rectangular slot 28 are provided with sliding openings 27 for the slide plate 7 to slide back and forth. The cross section of the slide plate 7 is convex-shaped, and the inner wall of one side of the rectangular slot 28 is fixedly connected to the positioning rod 30, and the slide plate 7 and the plug shaft 25 are both slidably connected to the positioning rod 30.

[0035] The positioning rod 30 is provided with a spring 29, one end of the spring 29 is fixedly connected to the positioning rod 30, and the other end of the spring 29 is fixedly connected to the inner wall of the rectangular slot 28, pushing the casting frame 8, and the two sliders 15 will slide along the slide groove, thereby adjusting the position of the casting frame 8. At this time, one end of the plug shaft 25 is engaged with the circular groove 26. When the position of the casting frame 8 is adjusted, the slide plate 7 is manually pushed to move it along the rectangular slot 28, and the positioning rod 30 and the plug shaft 25 slide relative to each other at the same time. The spring 29 is deformed, and the plug shaft 25 is disengaged from the circular groove 26 after moving. Then, the slide bar 4 can be moved vertically downward until the slot at the bottom of the slide bar 4 is engaged with the corresponding block 3, which can effectively prevent the casting frame 8 from continuing to slide along the slide groove, so that the position of the casting frame 8 can be adaptively adjusted according to actual usage.

[0036] In the present invention, during casting, a rotary forklift is used to move the assembled insulation box 1 and the casting frame 8 simultaneously to the front of the electric furnace (not shown), the center of the casting frame 8 is aligned with the center of the electric furnace, and then the melted slurry is cast into the interior of the casting frame 8, and the slurry flows into the interior of the diversion chamber 22. The lower inner wall of the diversion chamber 22 is arranged in an arc shape, and the height of the middle part of the lower inner wall is the highest.

The slurry can be discharged through multiple openings 9, and then flow out from each arc-shaped guide tube 16, and enter the interior of each product sand mold 18 through multiple casting tubes 19 to complete the casting process. The effect of casting multiple product sand molds 18 at the same time can be achieved, and the casting efficiency is high. When casting multiple product sand molds 18, there is no need to move the insulation box 1 multiple times, which is beneficial to reducing the waste of slurry and is beneficial to the casting process of small-sized electrofused corundum products.

[0037] During the casting process, when it is not necessary to cast all the product sand molds 18 placed in the insulation box 1, an appropriate amount of blocking plates 13 can be inserted into the corresponding two limit bars 10. When the blocking plate 13 fits the surface of the two positioning ports 6, one side surface of the blocking plate 13 is tightly attached to the outer surface of the casting frame 8, and the connection is sealed. At this time, the blocking plate 13 can seal and block the opening 9, and then one end of each screw 14 is passed through the threaded hole 31 and threadedly connected to the threaded hole 31 until one end of the screw 14 is tightly attached to the inner wall of the corresponding groove, which can effectively prevent the blocking plate 13 from moving at will, so that the blocking plate 13 can effectively seal and block the opening 9 for a long time, and can also be adjusted according to actual use. According to the usage, the sealing strip 12 is inserted into the inside of the two positioning grooves 24. The sealing strip 12 has good sealing performance when connected to the inner walls of the two positioning grooves 24 and the inner wall of the diverter cavity 22, and the lower surface of the sealing plate 20 is sealed with the lower inner wall and the inner walls on both sides of the diverter cavity 22. Then, one end of each bolt 11 is passed through the sealing strip 12 and threadedly connected to the connecting groove, so that the inside of the diverter cavity 22 can be divided into two non-connected parts. The position of the product sand mold 18 can be cast according to actual needs, and the molten liquid can be cast into the corresponding part in the diverter cavity 22.
