Description

Technical Field

[0001] The utility model relates to the technical field of experimental molds, and more specifically to a refractory material pore penetration experimental mold. Background Art

[0002] Refractory material is a kind of non-metallic material that can withstand high temperature. Generally speaking, it is an inorganic material, and its refractoriness can exceed 1580 degrees. It has the functions of high temperature resistance, deformation resistance and erosion resistance. Refractory materials are needed in large quantities in the metallurgical production process, but the service conditions at different positions in the converter have different requirements for refractory materials. Refractory materials need to have certain air permeability. In order to detect the pore penetration performance of refractory materials, it is necessary to carry out pore penetration test on the processed refractory materials. This test is crucial for many applications, such as high temperature reactors, furnaces, kilns, etc., because the pore penetration performance can affect the thermal conductivity, thermal expansion and chemical reaction properties of the material.

[0003] According to a refractory pore penetration test mold and method disclosed in patent number CN 111678852 A, the invention includes a liquid inlet, a liquid reservoir, a bracket, a switch, a connecting pipe, a seal, a molding container, a detection container, a liquid inlet pipe, a guide pipe and a water stop valve. It uses liquid to penetrate the refractory material to simulate the penetration of the pores of the refractory material, and then detects the pore penetration of the refractory material by measuring the volume of the penetrating liquid, so that the standard of the pore inertia of the refractory material can be quantified. However, the structure of the existing refractory pore penetration test mold is relatively fixed and single, and the pore penetration of only one refractory material can be detected at a time. In practice, there are many types of refractory materials produced, and the workload of detecting one by one is large, and the detection efficiency is very low; and the existing device detects the pore penetration of the refractory material only by measuring the volume of the penetrating liquid to detect the pore penetration of the refractory material. The detection method is relatively single, and there is a large error in the detection result. For this reason, we propose a new refractory pore penetration test mold. Utility Model Content

The transmission rod 15 rotates to make the cam 19 at one end press the adjustment plate 11 downward. At this time, the spring 13 is compressed, and the adjustment plate 11 moves downward to drive the slide bar 12 to move downward.

During the process of the gas passing through the first connecting pipe 23, the pressure value on the first pressure gauge 24 is observed. The gas after passing through the first connecting pipe 23 enters the installation box 25, passes through the through hole of the refractory material and reaches the second connecting pipe 32.

[0054] Step 3: Continue to control the servo motor 18 in the driving mechanism to work, so that the cam 19 at the other end of the transmission rod 15 is pressed down, driving all the piston blocks 8 on the other side of the support plate 2 to move down, and detecting the pore penetration results of the three refractory materials on the other side of the support plate 2;

[0055] Step 4: Use liquid to penetrate the refractory material to simulate the permeability of the pores of the refractory material, control the piston blocks 8 on the left and right sides of the support plate 2 to be in a symmetrical state, at this time, the inner cavity of the liquid storage tank 7 is connected to the outside through the liquid inlet 20, and liquid is injected into the liquid storage tank 7 through the liquid inlet hopper 21, and the start time of the experiment is recorded; the liquid flows into the installation box 25 through the first connecting pipe 23, and part of the liquid that penetrates the refractory material enters the second connecting pipe 32, and enters the detection container 34 through the second connecting pipe 32, and the end time and the volume of the liquid that penetrates the detection container 34 are recorded;

[0056] Step 5: Combining the experimental results of the two detection methods, determine the gas penetration performance of the refractory material.
