Compressive strength is one of the important standards that reflect the quality of refractory materials. Compressive strength refers to the ultimate load that refractory materials can withstand per unit area at a certain temperature. It is an important performance indicator for measuring the quality of refractory materials and indirectly reflects the organizational structure of the product, such as density, uniformity, sinterability, etc. It is usually divided into room temperature compressive strength and high temperature compressive strength. Room temperature compressive strength refers to the value measured at room temperature for the product; the sample is heated to a specified temperature for a pressure test, and the result obtained is called high temperature compressive strength at that temperature.

The right end of the test shaft 7 passes through the main body 4 and is fixed to the pressure head 3.

[0029] When in use, the refractory material is placed in the blocking device, and then the pressure sensor 6 is continuously pushed through the output end of the hydraulic device 1. The test shaft 7 of the pressure sensor 6 slides to the right, and the test shaft 7 drives the pressure head 3 to continuously push to the right to apply pressure to the refractory material in the blocking device. When the pressure head 3 applies pressure to the refractory material, the pressure sensor 6 will detect the corresponding pressure value and feed it back to the data display 5. After the detection is completed, the hydraulic device 1 stops and the pressure head 3 returns to the initial position.

[0030] The first embodiment of the blocking device includes two clamping plates 71 and a baffle plate 72 fixedly arranged horizontally on the right side of the body 4. The two clamping plates 71 are arranged in the up-down direction. The upper end surfaces of the right ends of the two clamping plates 71 are provided with clamping holes 75. The baffle plates 72 pass through the clamping holes 75 of the two clamping plates 71. A force-bearing head 73 is fixedly arranged on the left side of the middle section of the baffle plate 72. The bottom end of the baffle plate 72 is plugged with a bottom block 74. When in use, the baffle plate 72 is passed downward through the clamping hole 75 of the upper clamping plate 71 and the clamping hole 75 of the lower clamping plate 71, and then the bottom end of the baffle plate 72 is plugged into the bottom block 74. , place the refractory material between the two clamping plates 71 between the pressure head 3 and the force-bearing head 73, and then start the hydraulic device 1. The output end of the hydraulic device 1 continuously pushes the pressure sensor 6. The test shaft 7 of the pressure sensor 6 drives the pressure head 3 to continuously push to the right, exerting pressure on the refractory material. The refractory material is forced to move to the right and is blocked by the force-bearing head 73, preventing the refractory material from moving. When the pressure head 3 applies pressure to the refractory material, the pressure sensor 6 will detect the corresponding pressure value and feed it back to the data display 5. After the detection is completed, the hydraulic device 1 stops and the pressure head 3 returns to the initial position.

[0031] In this embodiment, the pressure head 3 and the force-bearing heads 73 and 83 are all blocks of 40 mm*40 mm*40 mm.

[0032] The second embodiment of the blocking device, the blocking device includes two clamping plates 81 and a baffle 82 horizontally fixedly arranged on the right side of the main body 4, the two clamping plates 81 are arranged in the up-down direction, the upper end surface of the right end of the upper clamping plate 81 is provided with a clamping hole 85, the bottom end of the baffle 82 passes through the clamping hole 85 of the upper clamping plate 81 and contacts with the upper end surface of the lower clamping plate 81, a force head 83 is fixedly arranged on the left side surface of the middle section of the baffle 82, and a bottom block 84 is slidably arranged on the lower end surface of the lower clamping plate 81 in the left and right directions.
