Description

Technical Field

[0001] This utility model relates to a viscosity tester for continuous casting slag, belonging to the technical field of continuous casting slag testing equipment. Background Technology

[0002] Slag viscosity is an important physical property of the mold flux in continuous casting molds. Monitoring the slag viscosity of mold flux is essential in continuous casting production, as the monitoring results help producers and users correctly select and rationally control the quality of mold flux. Currently used slag viscosity testers require at least two feeding operations to meet the testing requirements. During feeding, the high-temperature crucible must be clamped in and out with fixtures, which poses drawbacks such as the risk of burns to operators, operational safety issues, and long testing times. Therefore, improvements are necessary. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a continuous casting slag viscosity tester that is convenient for feeding. This slag viscosity tester can feed without removing the crucible, which significantly shortens the testing time and improves the safety of operation.

[0004] The technical solution to the above technical problem is:

[0005] A continuous casting slag viscosity tester with convenient feeding includes a heating corundum tube and a high-temperature crucible. The high-temperature crucible is placed in the inner cavity of the heating corundum tube. The improvement is that a retainer is provided at the upper end of the heating corundum tube, and a feed pipe is connected to the retainer. The upper end of the feed pipe is connected to a feeding funnel, and the lower end of the feed pipe is opposite to the high-temperature crucible.

[0006] The aforementioned continuous casting slag viscosity tester, which facilitates feeding, features a disc-shaped clamping seat. The diameter of the disc is larger than the inner diameter of the heating alumina tube. The lower edge of the disc is stepped, with the circumference of the lower part of the step matching the inner diameter of the heating alumina tube. The lower stepped part of the disc clamps into the inner diameter of the heating alumina tube.

[0007] The aforementioned continuous casting slag viscosity tester with convenient feeding has a central hole in the clamp seat, the diameter of which matches the outer diameter of the feed pipe. The feed pipe is inserted into the central hole of the clamp seat and is fixedly connected to the central hole of the clamp seat.

[0008] The aforementioned continuous casting slag viscosity tester with convenient feeding has a handle fixed to the side of the cassette. The handle is a long rod, with the front end of the handle connected to the top surface of the cassette by bolts, and the rear end of the handle located outside the heating corundum tube.

[0009] The beneficial effects of this utility model are:

[0010] The holder of this utility model is placed at the upper end of the heating corundum tube and can support the feed tube; there is a feeding funnel at the upper end of the feed tube, and the protective slag can enter the high-temperature crucible in the furnace through the feeding funnel and the feed tube to be heated and melted; the handle can be placed and removed from the holder to avoid the high temperature of the heating corundum tube affecting the operator.

[0011] This invention has a simple structure and is easy to use. It eliminates the need to clamp the high-temperature crucible in and out when adding material, thus preventing the temperature of the high-temperature crucible from dropping, shortening the detection time, and improving the safety of operation.

[0013] The following are the markings in the diagram: 1. Heating corundum tube; 2. High-temperature crucible; 3. Holder; 4. Feed pipe; 5. Feeding funnel; 6. Handle. Detailed Implementation

[0014] This utility model consists of a heating corundum tube 1, a high-temperature crucible 2, a clamping seat 3, a feed pipe 4, a feeding funnel 5, and a handle 6.

[0015] The figure shows that the high-temperature crucible 2 is placed inside the heating corundum tube 1, which heats the high-temperature crucible 2. The holder 3 is placed at the opening of the heating corundum tube 1, and the feed pipe 4 is connected to the holder 3. The upper end of the feed pipe 4 is connected to the feeding funnel 5, and the lower end of the feed pipe 4 is aligned with the high-temperature crucible 2. The feed pipe 4 is made of high-purity graphite and will not be affected by high temperature.

[0016] As shown in the figure, the holder 3 is a disc. The diameter of the disc of the holder 3 is larger than the inner diameter of the heating alumina tube 1. The lower edge of the disc of the holder 3 is stepped. The circumference diameter of the lower part of the step matches the inner diameter of the heating alumina tube 1. The lower step of the disc of the holder 3 is locked in the inner hole of the heating alumina tube 1, which can ensure that the holder 3 will not move and can also be easily removed.

[0017] As shown in the figure, there is a circular hole in the center of the card holder 3. The diameter of the circular hole matches the outer diameter of the feed tube 4. The feed tube 4 is inserted into the circular hole in the center of the card holder 3 and is threadedly fixed to the circular hole in the center of the card holder 3.

[0018] As shown in the figure, a handle 6 is fixed to the side of the card holder 3. The handle 6 is a long rod, and its front end is connected to the top surface of the card holder 3 by bolts. The rear end of the handle 6 is located on the outside of the heating alumina tube 1. The handle 6 can be used to place and remove the card holder 3 to avoid the impact of the high temperature of the heating alumina tube 1 on the operator.

[0019] The usage process of this utility model is as follows:

[0020] The operator holds handle 6 and places the clamp 3 on the upper end of the heating corundum tube 1, with the lower step of the clamp 3 locking into the upper opening of the heating corundum tube 1. The lower end of the feed pipe 4 connected to the clamp 3 is aligned with the high-temperature crucible 2. The operator pours the decarburized protective slag into the feeding funnel 5 using a cup. The protective slag enters the high-temperature crucible 2 inside the furnace through the feeding funnel 5 and the feed pipe 4, where it is heated and melted. The above operation is repeated until the melted crystallizer protective slag meets the detection requirements. This operation avoids the need to repeatedly add material after clamping the high-temperature crucible 2, shortens the detection time, improves operational safety, and thus increases detection efficiency.

[0021] An embodiment of this utility model is as follows:

[0022] The outer diameter of the heated corundum tube 1 is 90mm, the inner diameter is 80mm, and the height is 800mm;

[0023] The high-temperature crucible 2 has a diameter of 75 mm and a height of 120 mm;

[0025] The feed pipe 4 has a diameter of 55mm and a length of 900mm;

[0026] The upper diameter of the feeding funnel 5 is 130mm and the height is 100mm;

[0027] The handle 6 is 150mm long, 30mm wide, and 20mm thick.
