Description

Technical Field

[0001] The utility model belongs to the technical field of slag erosion resistance experiment, in particular to a refractory material slag erosion resistance experiment device. Background Art

[0002] The slag erosion resistance test is an experiment used to evaluate the ability of refractory materials and ceramic products to resist slag erosion, penetration and scouring in high temperature environments. It is of great significance for optimizing material properties, improving production processes and improving product quality.

[0003] One of the most commonly used methods for studying the erosion mechanism of refractory materials in the laboratory is called the static crucible method, which is to make the refractory material into a small crucible or directly drill a concave hole on the refractory product, put a certain amount of slag in it, place it in an electric furnace and heat it to a certain temperature and keep it warm for a certain time, then take it out to observe the erosion situation, or cut the cross section to measure the erosion depth. In the current static crucible method experiment, the slag is loaded into the refractory crucible sample and placed in a high-temperature furnace. The refractory material and the slag are heated from room temperature to a certain temperature together, and then naturally cooled with the furnace after keeping warm for a certain time. In industrial applications, the refractory material and the slag are in direct contact and react at a constant temperature. Due to the long heating and cooling time in the current static crucible method experiment, the refractory material reacts with the slag during the heating and cooling process, and it is difficult to truly reproduce the slag erosion resistance of the refractory material in industrial applications. If the electric furnace is heated in advance, the furnace will have a higher temperature, making it difficult for the experimental material to be conveniently placed in the center of the electric furnace for heating. If the experimental material is not placed in the center of the furnace, the experimental material will be heated unevenly, thus affecting the experimental results.

[0004] To this end, the utility model provides a refractory material slag erosion resistance test device. Utility Model Content

When the temperature inside the heating furnace 1 is sufficient, a pair of electric cylinders 19 are started to drive the sliding partition 18 to rise, and then the first motor 15 is started to drive the screw rod 14 to rotate, thereby driving the carrier frame 16 to move toward the inside of the heating furnace 1, so that the experimental material above the carrier plate 17 is sent into the interior of the heating furnace 1, and then the electric cylinder 19 is started again to lower the sliding partition 18, and the heating furnace 1 is closed to reduce the heat loss inside the heating furnace 1. After the experiment is completed, the reverse operation is performed to take the experimental material out of the heating furnace 1. Through the above structure, when the temperature inside the furnace is too high, the experimental material can be automatically sent to the middle position inside the heating furnace 1, so that the experimental material can be heated evenly, thereby reducing the impact on the experimental results.

[0023] like Figures 1 to 4As shown, a second fixed plate 2 is fixedly connected to the bottom of the heating furnace 1; a second motor 21 is fixedly connected to the top of the second fixed plate 2; a rotating shaft 22 is fixedly connected to the output end of the second motor 21; the other end of the rotating shaft 22 extends to the inside of the heating furnace 1; a rotating rod 23 is fixedly connected to the top of the rotating shaft 22; a turntable 24 is rotatably connected to the middle of the carrier 16; a fixed column 25 is fixedly connected to the bottom of the turntable 24; when working, the experimental material is placed on the top of the turntable 24, and when the carrier 16 is sent into the interior of the heating furnace 1, the rotating rod 23 will come into contact with the fixed column 25. After the experimental material is moved into place, the second motor 21 is started to drive the rotating shaft 22 and the rotating rod 23 to rotate, so that the rotating rod 23 moves the fixed column 25, and then the fixed column 25 drives the turntable 24 to rotate, so that the experimental material can rotate while being heated, thereby improving the heating uniformity of the experimental material, so that the experimental material can be heated more evenly, thereby reducing the occurrence of the situation where the uneven heating affects the experiment.

[0024] like Figure 1 to Figure 2 As shown, a cover plate 3 is rotatably connected to the middle part of the side wall of the heating furnace 1; a pair of spring buckles 31 are fixed to the side wall of the first fixed plate 12; during operation, after the experimental materials are placed on the top of the supporting plate 17, the cover plate 3 is rotated so that the cover plate 3 closes the space between the heating furnace 1 and the first fixed plate 12, and the cover plate 3 is limited and fixed by the spring buckles 31, and then when the sliding partition 18 rises, part of the heat inside the heating furnace 1 will be blocked by the cover plate 3, reducing the influence of the external low-temperature air on the internal temperature of the heating furnace 1, reducing the heat loss inside the heating furnace 1, keeping a higher temperature inside the heating furnace 1, and reducing the influence of temperature changes on the experiment.

[0025] like Figure 1 to Figure 2 As shown, a fixed shaft 4 is fixedly connected to the middle of the heating furnace 1; a torsion spring 41 is installed in the middle of the fixed shaft 4; during operation, when the heat inside the heating furnace 1 is dissipated to the space between the heating furnace 1 and the first fixed plate 12, the cover 3 will heat up due to this part of the heat, so when the cover 3 is opened to take out the experimental materials, it may cause burns to people. Through the setting of the fixed shaft 4 and the torsion spring 41, when the restriction on the cover 3 is released by operating the spring buckle 31, the cover 3 will automatically pop open, so that the experimental materials can come into contact with the external low-temperature air, thereby quickly cooling down and reducing the occurrence of burns to people.

[0026] like Figures 1 to 4As shown, a first gear 5 is fixedly connected to the middle of the rotating shaft 22; the first gear 5 is located below the heating furnace 1; a pair of rotating rods 51 are rotatably connected to the bottom of the heating furnace 1; a second gear 52 is fixedly connected to the middle of the pair of rotating rods 51; the second gear 52 and the first gear 5 are meshingly arranged; two groups of fan blades 53 are fixedly connected to the middle of each rotating rod 51; the two groups of fan blades 53 are respectively located inside the heating furnace 1 and outside the heating furnace 1; when working, as the rotating shaft 22 rotates, the transmission between the first gear 5 and the second gear 52 drives the multiple fan blades 53 to rotate, so that the high-temperature air inside the heating furnace 1 flows, so that the temperature of the experimental materials rises more evenly, and the second motor 21 can dissipate heat at the same time.

[0027] like Figures 1 to 4 As shown, a plurality of heat-conducting fins 6 are fixedly connected to the middle of the rotating shaft 22; the plurality of heat-conducting fins 6 are located between the second motor 21 and the first gear 5; during operation, the heat inside the heating furnace 1 will heat up the rotating shaft 22, thereby causing a certain impact on the rotating shaft 22 under heat conduction. By setting a plurality of heat-conducting fins 6, the heat dissipation speed of the rotating shaft 22 is improved, and the heat conduction to the second motor 21 and the impact on the second motor 21 are reduced.

[0028] like Figures 1 to 3 As shown, a plurality of baffle bars 7 are fixedly connected to the middle of the carrier frame 16; the other ends of the plurality of baffle bars 7 are fixedly connected to the middle of the carrier plate 17; during operation, the setting of the plurality of baffle bars 7 can reduce the occurrence of experimental materials being thrown out from the top of the turntable 24 and falling.

[0029] During operation, the temperature inside the heating furnace 1 is raised to the experimental temperature through the heating component, and then the materials to be tested are placed above the carrier plate 17. When the temperature inside the heating furnace 1 is sufficient, a pair of electric cylinders 19 are started to drive the sliding partition 18 to rise, and then the first motor 15 is started to drive the screw rod 14 to rotate, thereby driving the carrier frame 16 to move toward the inside of the heating furnace 1, so that the experimental materials above the carrier plate 17 are sent into the interior of the heating furnace 1, and then the electric cylinder 19 is started again to lower the sliding partition 18, and the heating furnace 1 is closed to reduce the heat loss inside the heating furnace 1. After the experiment is completed, the experimental material is taken out from the inside of the heating furnace 1 by reverse operation, and the experimental material is placed on the top of the turntable 24. When the carrier 16 is sent into the inside of the heating furnace 1, the rotating rod 23 will come into contact with the fixed column 25. After the experimental material is moved into place, the second motor 21 is started to drive the rotating shaft 22 and the rotating rod 23 to rotate, so that the rotating rod 23 moves the fixed column 25, and then the fixed column 25 drives the turntable 24 to rotate, so that the experimental material can rotate while being heated, thereby improving the heating uniformity of the experimental material. When the experimental material is placed on the carrier plate 17, the rotating shaft 22 and the rotating rod 23 are driven to rotate. After that, the cover plate 3 is rotated so that the cover plate 3 closes the space between the heating furnace 1 and the first fixed plate 12, and the cover plate 3 is limited and fixed by the spring buckle 31. Then, when the sliding partition 18 rises, part of the heat inside the heating furnace 1 will be blocked by the cover plate 3, reducing the influence of the external low-temperature air on the internal temperature of the heating furnace 1 and reducing the heat loss inside the heating furnace 1. When the heat inside the heating furnace 1 is dissipated to the space between the heating furnace 1 and the first fixed plate 12, the cover plate 3 will be heated up due to this part of the heat, so when the cover plate 3 is opened to take out the experimental materials, it may cause burns to personnel. The setting of the fixed shaft 4 and the torsion spring 41 can make the cover 3 automatically pop open when the restriction on the cover 3 is released by operating the spring buckle 31. As the rotating shaft 22 rotates, the transmission between the first gear 5 and the second gear 52 drives the multiple fan blades 53 to rotate, so that the high-temperature air inside the heating furnace 1 flows, and the temperature rise of the experimental materials is more uniform. At the same time, the second motor 21 can be dissipated. The heat inside the heating furnace 1 will cause the rotating shaft 22 to heat up, thereby causing a certain impact on the rotating shaft 22 under heat conduction. The setting of multiple heat-conducting fins 6 can improve the heat dissipation speed of the rotating shaft 22.
