Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgy, and particularly relates to a corundum boat for measuring the melting point and melting rate of slag. Background Art

[0002] The melting condition of slag plays a very important role in both ironmaking and steelmaking production. The properties of slag determine the composition of molten iron and the quality of molten steel in blast furnace production. It is often said that the key to blast furnace ironmaking lies in slag smelting. And the melting point of slag is an important index of slag, and the melting point is also the melting temperature of slag.

[0003] The general method for measuring the melting temperature is to grind the slag into fine powder, make it into a triangular pyramid shape, place it on an ash cone tray, put the ash cone tray into the card slot of the corundum boat and then put it into the test equipment for testing.

[0004] During the experiment, the corundum boat used in the experiment has a relatively high test temperature. If continuous testing is to be achieved and it is carried out under the condition that the temperature has not completely cooled and still has a certain temperature, it is a bit difficult to place the ash cone tray into the card slot. Because when the corundum boat is dragged out of the furnace after the test, due to the structural and dimensional limitations of the corundum boat in the prior art and the reason of gravity during use, the part of the corundum boat extending out of the furnace will tilt downward, making the ash cone tray also tilt downward and unable to maintain stability. It is not easy to keep the test sample stable when placed on it, resulting in difficulty in placing the sample and affecting the next test.

[0005] In view of the above factors, a corundum boat for measuring the melting point and melting rate of slag is specially designed to reduce the downward tilt degree of the part of the corundum boat extending out of the furnace body, ensuring the stability when the test sample is placed. Improving the structure and dimensions of the corundum boat will not affect the normal test of the test sample in the middle of the corundum boat in the high-temperature area of the furnace. Content of the Utility Model

[0006] The purpose of the utility model is to provide a corundum boat for measuring the melting point and melting rate of slag, so as to solve the problems put forward in the above background art.

[0007] The purpose of the utility model is realized by the following technical solutions: A corundum boat for measuring the melting point and melting rate of slag, including a corundum boat and an ash cone tray cooperating with the corundum boat. The corundum boat is detachably connected to the ash cone tray, and the corundum boat is in a semi-cylindrical structure or a concave structure;

[0008] The corundum boat is in a semi-cylindrical or concave structure, and a card slot is arranged on the corundum boat for cooperating with the ash cone tray.

[0009] Furthermore, the corundum boat is in a semi-cylindrical structure, the corundum boat is hollow, and a card slot is arranged at the end face of the corundum boat, and the diameter of the card slot is the same as the diameter of the ash cone tray.

[0010] Further, a support column with a triangular structure is arranged inside the corundum boat, and the support column is in plug-in fit with the grey cone tray.

[0011] Further, the corundum boat has a semi-cylindrical structure, is hollow, and a clamping groove is arranged at the end face of the corundum boat, and the diameter of the clamping groove is the same as the diameter of the grey cone tray.

[0012] Further, the main body of the corundum boat is 260 mm long and 35 mm wide.

[0013] Further, the corundum boat has a concave-shaped structure, is hollow, and clamping grooves are arranged at intervals on the inner wall of the corundum boat, and the length of the clamping groove is the same as the thickness of the grey cone tray.

[0014] Further, a plurality of the clamping grooves are arranged at intervals, and positioning holes are arranged in the vertical direction of the clamping grooves, and the positioning holes are matched with the fixing holes on the grey cone tray.

[0015] Further, the main body of the corundum boat is 260 mm long and 35 mm wide, and the height of a single clamping groove is the same as the thickness of the grey cone tray.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] In the present utility model, the blast furnace slag is ground into a triangular pyramid shape and placed on the grey cone tray. When the test furnace still has a certain temperature, the corundum boat is pulled out, so that the clamping groove and the part in front of the clamping groove are exposed outside the furnace and the corundum boat is kept stable, and then the grey cone tray is placed at the reserved position of the corundum boat. After being placed stably, it is pushed into the test furnace. As the temperature of the test furnace slowly rises, the conical sample gradually melts with the increase of the furnace temperature, and the test is completed according to the normal process.

[0018] In the using state of the present utility model, the downward inclination degree of the part of the corundum boat extending outside the furnace is reduced, ensuring the stability of the test sample during placement.
